Security systems have become standard equipment in stores and other businesses, and they’re becoming increasingly common in private homes as well. If you’ve ever shopped for a home security system, then you know there are a wide variety of options available. These systems range from do-it-yourself kits you can pick up for $10 to sophisticated whole-house security networks that must be installed by professionals. But, as it turns out, most alarm systems are actually built around the same basic design concepts.

Breaking the Circuit

Other than the family dog, the most basic burglar alarm is a simple electric circuit built into an entry way. In any circuit, whether it’s powering a flashlight or a computer, electricity only flows when you give it a path between two points of opposite charge. To turn the electricity on or off, you open or close part of the circuit.

To open or close a flashlight circuit, you simply throw a switch. In a burglar alarm, the switch detects the act of intrusion — opening a door or window, for example. These sorts of alarms are divided into two categories:

In a closed-circuit system, the electric circuit is closed when the door is shut. This means that as long as the door is closed, electricity can flow from one end of the circuit to the other. But if somebody opens the door, the circuit is opened, and electricity can’t flow. This triggers an alarm.

In an open-circuit system, opening the door closes the circuit, so electricity begins to flow. In this system, the alarm is triggered when the circuit is completed.

There are a number of ways to build this sort of circuit into an entry way. Closed circuits are normally a better choice than open circuits because an intruder can deactivate the open circuit by simply cutting the connected wires.

A magnetic sensor in a closed circuit consists of a few simple components. For the most basic design, you need:

• a battery powering a circuit
• a spring-driven metal switch built into a door frame
• a magnet embedded in the door, lined up with the switch
• a separately-powered buzzer with a relay-driven switch.

When the door is closed, the magnet pulls the metal switch closed so the circuit is complete. The current powers the relay’s electromagnet, so the buzzer circuit stays open. When you move the magnet by opening the door, the spring snaps the switch back into the open position. This cuts off the current and closes the relay, sounding the alarm.

You can also build this sort of system into a window. If an intruder pushes a window open, the magnet slides out of line with the switch, and the buzzer is activated.

Another simple burglar alarm uses a small button as the switch. The button is embedded in the door frame, so closing the door pushes it in. When somebody opens the door, the button is released, changing the circuit and sounding the alarm.

With just a battery and buzzer, these designs make for fairly flawed security systems. After all, the burglar only needs to close the door again to turn the buzzer off. That’s why most modern burglar alarms incorporate another piece into the circuit — the control box.

The control box is hooked up to one or more alarm circuits, but it also has its own power supply. It monitors the circuits and sounds the alarm when they are closed or opened (depending on the design). But once the alarm is triggered, the control box won’t cut it off until somebody enters a security code at a connected keypad. For added security, the control box is usually positioned in an out-of-the-way spot, so the intruder can’t find it and attempt to destroy it.

Using this basic concept, you can create all sorts of alarm systems. Just imagine what a burglar might do to break into a house, and then turn that action into the circuit switch. For example, an intruder might break through a window, so you could make the glass itself a circuit. The easiest way to do this is run a current through a thin line of foil wire affixed to the surface of the glass. If a burglar breaks the glass, the circuit is broken, and the alarm is triggered.

Floor mats are another simple option. A basic floor mat uses an open circuit design with two metal strips spaced apart. When somebody steps on the mat, the pressure pushes the two metal strips together, completing a circuit.

All of these circuit systems are best for guarding the perimeter of a house or business — the points an intruder would enter the building. In the next section, we’ll look at systems that detect an intruder once he or she has already made it inside.

Detecting Motion

Circuit alarms are very effective for guarding the perimeter of a house, but they don’t work so well inside a building. This is because the intruder’s actions are highly unpredictable — you don’t know where they’ll go or what they’ll touch. A specific “trigger” isn’t very effective. To detect an intruder who’s already in the house, you need a motion detector.

Basic motion detectors are fairly common these days. You see them all the time in automatic doors, for example. There are several different sorts of detectors.

An automatic door opener is an example of a radar-based motion detector. The box above the door sends out bursts of microwave radio energy (or ultrasonic sound waves), and then waits for the reflected energy to bounce back. If there is nobody in front of the door, the radio energy will bounce back in the same pattern. But if somebody enters the area, the reflection pattern is disturbed. When this happens, the sensor sends a signal and the door opens. In a security system, the sensor sends an alarm signal when the reflection pattern in a room is disturbed.

Another simple design is a photo-sensor motion detector. These are the devices you might see in a store at a shopping mall. When somebody enters the store, the motion detector sounds a chime or bell. Photo-sensors have two components:

• a source of focused light (often a laser beam)
• a light sensor

In a home security system, you aim the beam at the light sensor, across a passageway in your house. When somebody walks between the light source and the sensor, the path of the beam is blocked briefly. The sensor registers a drop in light levels and sends a signal to the control box.

More advanced security systems include passive infrared (PIR) motion detectors. These sensors “see” the infrared energy emitted by an intruder’s body heat. When an intruder walks into the field of view of the detector, the sensor detects a sharp increase in infrared energy. Of course, there will always be gradual fluctuation of heat energy in an area, so PIR detectors are designed to trigger the alarm only when infrared energy levels change very rapidly. See this page for details.

All these motion detector designs can be combined in a house to offer complete coverage. In a typical security system, the control box will not sound the alarm immediately when the motion detectors are triggered. There is a short delay to give the homeowner time to enter a security code that turns the system off.

If the security code is not entered, however, the control box will activate various alarms. In the next section, we’ll look at some of the alarm types you might find in a typical security system.

Sounding the Alarm

There are several things a security system might do when it detects an intruder. In an advanced system, the control box will be wired to several different components. Typically, it will activate:

• a siren or other loud alarm noise
• flashing outdoor lights
• a telephone auto-dialer
• The siren and lights serve three functions:
• They alert occupants and neighbors that someone has broken into the house.
• They drive the intruder away.
• They signal to police which house has been broken into.

The telephone auto-dialer can: Dial the police directly, and play a pre-recorded message giving the address of the house and any other relevant information. This message will usually play over and over so that the police will still hear it even if the call is put on hold for some time.

Dial the security company that installed the equipment. In this case, the control box can feed specific information about the intrusion — which circuits or motion detectors were activated, etc. The security company then relays this information to the police.

Home security is a rapidly growing field, and there are new and improved burglar alarms popping up all the time. For the most part, these systems are all built around the same basic structure. A central control box monitors several motion detectors and perimeter guards and sounds an alarm when any of them are triggered.

Your transmission is a remarkable contraption. Somehow it can shift your car from gear to gear, knowing how fast you need to go and how quickly you need to get there. What goes on inside is a mystery to most. Unless your thirst for automotive knowledge borders on compulsive, you can leave it a mystery. The basics will be enough to have an intelligent (which translates to “not about to be ripped off”) conversation with your mechanic.

Basic Parts of a Transmission

While there are many, many little parts inside, your transmission is essentially made up of a few key parts of systems.

Bell Housing: This is the cone shaped metal case that you can see when you peek underneath your car. If you have a front-wheel-drive car, it is stuck on the side of the engine under the hood. If your car is rear-wheel-drive, the transmission will be mounted underneath the car behind the engine.

Gears: Even though you are not shifting them, an automatic transmission has gears. They are broken into main gears and planetary gears. You need all of these to be able to drive.

Fluid: Transmission fluid is very important to an automatic transmission. All of the magic happens in the fluid. Most cars come with red transmission fluid, good to know if you are looking for a leak.

Filter: All of that fluid has to be clean for your car to shift gears at the right time. To keep things fresh, your transmission has a filter to catch any gunk.

Now that you know a little about what is happening in there, you can try to figure out why your transmission is acting up, or at least understand what your mechanic is talking about while he tries to make your bill into his new fishing boat.

Transmission problems fall into two very similar categories:

1.     Won’t go.

2.     Won’t go smoothly

These two groups of problems are caused by the same faults in your transmission, so whichever your car is doing, the following applies.

Is your fluid level correct?

It is important to check your transmission fluid at least twice a year. Not only can a low fluid level cause your car to shift poorly, it can eventually lead to transmission damage, and a costly repair. If your car seems to be losing fluid on a regular basis, you may have a leak.

Is your transmission leaking?

Checking for leaks is not as trying as it may seem. The transmission is a closed system, so there are only a few places that can spring a leak. Unless it has been changed to a non-dyed fluid, your car will have red transmission fluid. Here are a few places to check for leaks:

• At the filler tube base.
• At the drain hole underneath the transmission.
• Between the transmission and the engine.
• At the selector shaft - the rod that connects your gear shift to the transmission.
• Speed sensor-mounting point. Either this will be your cable screwing into the transmission housing or an electronic sensor bolted to the housing.
• The radiator. If your car has a transmission cooler, it is possible that a leak will cause transmission fluid to leak into the radiator fluid. They do not mix well, so you will see it floating around in there.

Is your filter clogged?

Your transmission’s filer is vital to its performance. If you have not replaced your filter in a while (or ever for a lot of us), be sure to do this before you start talking about rebuilds or replacements.

Most transmission problems cannot be fixed by the average do-it-yourselfer. There are just too many specialized tools and pieces of equipment you will need, and buying this expensive gear just to screw up your first three tries at fixing the thing just doesn’t make too much sense.

Now that you are in front of the firing squad, it is time to drop some knowledge on your fix-it person. Tell him what the car is doing. Then tell him what you found out when you inspected the transmission. If there is a leak, let him know where and how much is leaking.

Time for a rebuild?

When your transmission gets tired enough, you will have to have it rebuilt. It is true. For some makes and models of car, it is true a little too often, but that is unimportant. The important thing is checking any other possible causes to your problem before you take the transmission apart, which is very expensive. That is why I am here to help. On Repairfinders.com, you will find an affordable mechanic who won’t overcharge you, and who will do the best work possible. If you have not replaced your filter yet, do it! This fixes a nice percentage of transmission problems. If your filter is good, and nothing simple is out of adjustment, be prepared to drop some serious dough on the rebuild. The good news is that most shops warrantee transmissions rebuild for a nice amount of time, and on Repairfinders, it so easy to find a hardworking professional, because every business listed is hardworking, honest, reliable, and professional!

After mechanical wristwatches enjoyed a long, long run of popularity, watches that sported battery-operated quartz movements eventually replaced them. However, many people still collect, and even wear, mechanical wristwatches to this day. A tiny battery does not power mechanical wristwatches, which are also known as “Wind Ups”. Instead, what “makes them tick” are coiled mainsprings that are run by a series of springs, gears, and wheels. If you have one of these timepieces, you can learn how to repair common mechanical wristwatch problems.

Replace a Wristwatch Crystal
First, a crystal is the clear piece that covers the face or the dial of a watch. If the mechanical wristwatch has scratches on its crystal, an experienced jeweler can buff them out. Deep gouges may sometimes be buffed out, but not always.

The crystals on mechanical wristwatches are typically made of glass, plastic, or a manmade sapphire. Replacement crystals can be difficult to find, especially if the wristwatch is very old. Therefore, you may have to replace a broken crystal with a different material than the original one was made with. Fortunately, most watch crystals are round. Nevertheless, some timepieces were made with odd-shaped crystals, and replacements can be even harder to locate.

Once you locate a suitable replacement crystal for the mechanical wristwatch, you will need to remove the broken or damaged one first before you can make the repair. To do this, you will need to carefully remove the back off the watch. Then, carefully take the movement out of the casing. You will probably have to remove the crown first. The crown part is the small knob on the side of the wristwatch you use to wind it. After the movement is removed, push the crystal out of the bezel and insert the replacement crystal. Reverse the process to put your mechanical wristwatch back together again.

Although natural gas is by nature colorless and odorless, scents in the form of traces of mercaptans are usually added, to assist in identifying leaks. This odor commonly takes the form of rotting eggs. If this scent is detected, it is recommended to evacuate the area immediately, usually to the outside. Do not light fires/cigarettes, and do not operate electrical appliances/light switches/phones, as these may act as points of ignition. Once in a safe area, contact your natural gas provider.

Because of the Pipeline Safety Improvement Act of 2002 passed in the United States within the past few years, Federal Safety Standards require natural gas providing companies to conduct safety inspections for gas leaks in homes and other buildings receiving natural gas. The gas company is required to inspect gas meters and inside gas piping from the point of entry into the building to the outlet side of the gas meter for gas leaks. This requires entry into private homes by the natural gas companies in many cases.

Most state and federal agencies have adopted the Gas Piping and Technology Committee (GPTC) standards for grading natural gas leaks

A Grade 1 leak is a leak that represents an existing or probable hazard to persons or property, and requires immediate repair or continuous action until the conditions are no longer hazardous. Examples of a Grade 1 Leak are:

1. Any leak which, in the judgment of operating personnel at the scene, is regarded as an immediate hazard.

2. Escaping gas that has ignited.

3. Any indication of gas, which has migrated into or under a building, or into a tunnel.

4. Any reading at the outside wall of a building, or where gas would likely migrate to an out-side wall of a building.

5. Any reading of 80% LEL, or greater, in a confined space.

6. Any reading of 80% LEL, or greater in small substructures (other than gas associated sub structures) from which gas would likely migrate to the outside wall of a building.

7. Any leak that can be seen, heard, or felt, and which is in a location that may endanger the general public or property.

A Grade 2 Leak is a leak that is recognized as being non-hazardous at the time of detection, but justifies scheduled repair based on probable future hazard.

Examples of a Grade 2 Leak are:

A. Leaks Requiring Action Ahead of Ground Freezing or Other Adverse Changes in Venting Conditions. Any leak which, under frozen or other adverse soil conditions, would likely migrate to the outside wall of a building.

B. Leaks Requiring Action within Six Months

1. Any reading of 40% LEL, or greater, under a sidewalk in a wall-to-wall paved area that does not qualify as a Grade 1 leak.

2. Any reading of 100% LEL, or greater, under a street in a wall-to-wall paved area that has significant gas migration and does not qualify as a Grade 1 leak.

3. Any reading less than 80% LEL in small substructures (other than gas-associated substructures) from which gas would likely migrate creating a probable future hazard.

4. Any reading between 20% LEL and 80% LEL in a con-fined space.

5. Any reading on a pipeline operating at 30 percent SMYS, or greater, in a class 3 or 4 location, which does not qualify as a Grade 1 leak.

6. Any reading of 80% LEL, or greater, in gas associated sub-structures.

7. Any leak which, in the judgment of operating personnel at the scene, is of sufficient magnitude to justify scheduled repair.

A Grade 3 Leak is a leak that is non-hazardous at the time of detection and can be reasonably expected to remain non-hazardous.

Examples of a Grade 3 Leak are:

1. Any reading of less than 80% LEL in small gas associated substructures.

2. Any reading under a street in areas without wall-to-wall paving where it is unlikely the gas could migrate to the out-side wall of a building.

3. Any reading of less than 20% LEL in a confined space.

Sometimes your guitar just will not sound right. Since guitars are usually made out of wood, it is affected by changes in temperature and humidity. A guitar that is not periodically adjusted properly will never live up to its full potential.

Intonation: Poorly adjusted intonation can cause a guitar to sound out of tune. It will make your guitar to sound messy when playing open chords, or sound slightly out of tune when you play higher up on the neck. Once you develop a good ear, this will drive you crazy. You can easily find a repairperson on Repairfinders.com to fix this for you quickly.

Intonation on a guitar should be adjusted if you ever change the gauge (thickness) of strings you use, if you change the action (distance between string and fret board) and at least twice a year (winter/summer). Some people suggest checking every time you change strings, although this is probably not necessary.

Intonation on an electric guitar is adjusted by moving its bridge saddles forward or backward. A bridge saddle is the piece of metal on the bridge that the string rests on. These can be adjusted with a small screwdriver (some guitars use an Allen wrench.) Your goal when setting the intonation is to make an open string sound exactly the same as the 12th fret on that string. In order to do this you will need an electric tuner.
In theory, the distance from the nut to the 12th fret should be the same as the distance between the 12th fret and the saddle. The 12th fret is supposed to be the halfway point. In reality, when we press down on the 12th fret, the string stretches, so it will generally sound a slightly higher pitch. To offset this annoying bit of physics we must adjust the ‘length’ of the string by moving the bridge saddles. If you move the bridge saddle back, you will increase the length of the string, therefore the guitar will sound less sharp when you fret notes.

If you are confused, forget about what I told you for a second, and follow the simple directions below or hop onto Repairfinders.com and have a qualified professional look at this for you.

Hit the 12th fret harmonic on your Low E-string. (You do this by lightly touching -not pressing- the string just above the fret. Chances are you probably knew that already.) Then press your finger down and play the 12th fret naturally. Your tuner (or your ear) will probably tell you that the two notes are (at least) a little out of tune.

THE BASIC RULE FOR SETTING INTONATION
If the 12th fret (pressed) sounds sharper (higher in pitch) than the harmonic, move the saddle back (away from the neck and pickups) and turn the screw clockwise.
If the note sounds flat, (lower in pitch) compared to the harmonic, move the saddle forward (toward the pickups)

Very Important: Remember to tune the string back to E each time you make an adjustment, before checking the intonation again. Often enough, the screws need to be adjusted very little. A tiny turn can make a big difference so start slow. Once you have properly intonated one string move to the next, until you are done with all six strings. The whole process rarely takes more than a half hour once you get used to it, but it may take a little longer at first, so hang in there. Once you are able, you will be proud of yourself.

Also, remember that the guitar, by its very nature, is an imperfect instrument. It is impossible to adjust intonation 100% perfectly. This might be obnoxious if you have an incredibly good ear, but you will just have to get used to it or give up the guitar.

It will be easier to get good intonation from your guitar if you use heavier gauge strings. If you use anything below, gauge .010 strings you may have problems. Personally, I use gauge .011 stings. Some people have trouble playing with heavy strings, but I swear, once you get used to them you will never go back. I strongly recommend using at least gauge .010

Also, do not adjust the action of your guitar or the truss rod after fixing your intonation. You would just have to do it all over again. If you need to adjust these things, do it first. These are other factors that affect the intonation of your guitar. If you use light strings, you may need to move the saddles back further, the same holds true if your strings are far from the fret board.

You must always keep your instrument finely tuned if you wish to receive many years of wonderful music from it. This is only an example of how easily someone in your area can assist you. However, no matter what kind of instrument you have, or whatever problem you may be experiencing, do not fear! On Repairfinders.com, it will take you only a couple of minutes to find a local business in your area to fix your guitar, piano, flute, saxophone, or any other instrument! So what are you waiting for? Jack is over and out.

If you are thinking about remodeling your home or office, there are many things to consider. One of the biggest is “should I do it myself?” There is no easy answer to this question, but you can help yourself decide by considering the following questions:

1. Do I have the time?

Remodeling can take a considerable amount of time, even for the experts. Most of the time remodeling is actually more difficult than new construction. One of the reasons for this is that you have to prepare the existing components of your structure to blend in with the new.

2. Do I have the know-how?

Your remodeling project will likely require some specific skills to ensure a successful result. These can include carpentry, painting, drywall finishing, flooring, plumbing, electrical, concrete work, excavation, etc. You’ll want to carefully assess your abilities in the skills you’ll need for your own project.

3. Do I have the tools and equipment needed?

Since so many skills are involved, most property owners do not have the needed tools and equipment. If you can get the tools by purchasing, renting or borrowing them, do you have the skills to use them effectively and safely?

4. Do I have enough help?

Remodeling can be very labor intensive; two hands are often not enough. You can always use someone to help carry materials or equipment, or you might need skilled help in order to complete the job in a reasonable time. If you need help, will you have access to the kind of help you need, when you need it?

5. Am I physically able to do the work?

Remodeling is usually strenuous work, involving climbing ladders, working on scaffolds or heavy lifting. You’ll need to decide if you’re physically able to do that kind of work for the extended period your project may take.

6. Do I have a clear idea of what I am trying to accomplish?

Can you draw the necessary building plans, or will you need to get someone else to do this for you? You may need to hire an architect if your remodel is very complex. An architect can help with traffic flow and other factors that may arise when you change rooms, or move walls and doorways.

7. What is my budget?

You should make a careful estimate of all the costs of your project before any work is started. Calculate the costs of all materials, equipment rental, tools, labor, subcontractors etc. Don’t forget to add a budget for any unknowns or surprises that may be revealed later!

8. What kind of subcontractors am I going to need?

You will probably need some skilled subcontractors to perform specialized work that you can’t do. Do you have the time to deal with those subcontractors personally, and do you have the knowledge needed to negotiate with them? If you are unprepared in this area, it can cost you a lot later on.

You may decide when you’ve finished answering these tough questions that you’ll need some help. If you decide to hire a professional remodeling contractor, you should expect someone with years of experience in construction who can provide all the services listed above, including management of all the necessary subcontractors. Your contractor should take care of everything, and manage your project until it is completed in a timely and efficient manner.

Here’s how to find a good remodeling contractor:

1. Go to Repairfinders.com

On Repairfinders.com you will find only the best qualified professionals in your area. All it takes is a couple minutes of your time to find the right one that is best for you.

2. Check out references

Get previous customers’ opinion of the contractor and the work that was done. Talk to local vendors and suppliers to see if that contractor pays his or her bills.

3. Is the contractor local?

Does he or she have a local office, address or phone number? It’s easier to keep track of a local contractor; avoid hiring from out of town or state unless you thoroughly check them out.

4. Look at the contractor’s work

Make sure you look at previous projects or photos of completed work.

If you’re looking for someone who has roots locally and is likely to be around to stand behind the work done on your project, you might also find out if the contractor you’re considering is involved in the community or in non-profit organizations, or provides support for community projects.

A traditional fountain is an arrangement where water issues from a source, fills a basin of some kind, and is drained away. Fountains may be wall fountains or freestanding. In fountains, sheets of water may flow over varied surfaces of stone, concrete or metal. Basins may overflow from one into another, or the overflow may imitate a natural cascade. Many fountains are located in small, artificial, ornamental ponds, basins and formal garden pools, and often they include sculpture.

One of the most common features of a fountain, if there is enough pressure, is one or more jets, in which water is forced into the air under pressure to some height. A famous example of such a modern fountain rises from the surface of Lake Geneva.

Early fountains depended on the natural gravitational flow of water, from a spring or aqueduct supplied by a distant and higher source of water, which provided hydraulic head.

Hellenistic hydraulic engineers employed great originality in designing fountains, where the water pressure might be employed to animate automata and water organs.

 

 

Iraqi engineer and inventor al-Jazari first described reciprocating motion in 1206 when the kings of the Artuqid dynasty in Turkey commissioned him to manufacture a machine to raise water for their palaces. The finest result was a machine called the double-acting reciprocating piston pump, which translated rotary motion to reciprocating motion via the crankshaft-connecting rod mechanism.

Other early fountains were geometrically regularized springs, developed in the classic Persian garden. These gardens were typically enclosed and were designed to provide relaxation. The effect of sunlight was the main concern regarding the structural aspect of the Persian garden design. Shapes and textures were specifically chosen for their ability to direct sunlight. In the 16th century, elaborate fountain displays were garden features of Mannerist gardens of Central Italy and the Mughal gardens of India.

 

 

Early Modern English employed fountain to refer to a natural spring water or source, which the 16th century garden fountain might consciously imitate in a grotto.

Christian allegory made much use of the concept of the fountain, specifically the Fountain of Life, associated with the rebirth that was intended to be experienced at the Baptismal font. The Fountain of Life appears in Christian illuminated manuscripts of Late Antiquity, and elaborate Gothic fountains formed centerpieces for enclosed gardens. An offshoot of the Fountain of Life was the legend of the Fountain of Youth, which Juan Ponce de León sought in Florida. From the Fountain of Youth one can drink to gain immortality, or to regain one’s youth.

The practical Romans marked the delivery end of aqueducts with a public fountain, a practice that was revived in Rome in the 15th century, when the restored Aqua Felice once more delivered a symbolic presentation of its waters to Rome in the original Trevi Fountain, since replaced by the familiar Baroque fusion of water, architecture and sculpture.

Animated fountains often use laminar jets that provide water that moves like ping pong balls in animation, so that it breaks up, as the height varies, and the behavior of each jet operates independently with up to 5 Hz modulation frequency (1/5 second), so that the water packets collide with themselves. For example, such fountains can spit up one ball of water, which then explodes, showering people with a fine mist.

A musical fountain is a type of fountain that dances in time with recorded or live music, controlled either by a computer or by a live “organist” operating the fountain through a switchboard. Notable examples of this are fountains on Vasilievsky Island in St. Petersburg, Russia, and the fountains of the Bellagio in the Las Vegas Strip.

 

 

A splash fountain or bathing fountain is a fountain intended for people to cool off in. Although many fountains were not designed as bathing fountains, children of all ages often use them for that purpose. Some fountains are fenced in, or have raised edges as a barricade to keep people out. In other situations, fountains are designed to allow easy access, and feature nonslip surfaces, so that people can safely use them to cool off in on hot summer days.

Splash fountains have zero standing water, to eliminate possible drowning hazards, so that no lifeguards or supervision is required. These splash pads are often located in public pools, public parks, or public playgrounds (known as “spray grounds”).

 

 

A recent example of a public splash fountain, intended for water play, is the one located in Toronto’s Dundas Square. It consists of 600 ground nozzles arranged in groups of 30 (3 rows of 10 nozzles). Each group of 30 nozzles is located beneath a stainless steel grille. Twenty such grilles are arranged in 2 rows of 10, right in the middle of the main walkway through Dundas Square. Both the architects and the designers have confirmed that these were intended for water play, and the facility operators have confirmed that the water is treated to pool water quality standards, and that the health department tests the water quality, at least once a day. The entire surface of Dundas Square is made of special nonslip square granite slabs that match the size of the metal grilles. The special texture on the slabs ensures that they are not slippery when wet.

Spray fountains are designed to serve as a play area where children (and sometimes adults) can run around and cool off under a canopy of water. Spray fountains are becoming popular in areas where the construction of public pools is difficult or costly, such as urban areas. However, spray fountains can also be used to enhance a pool’s surrounding play area.

A water fountain or drinking fountain is designed to provide drinking water and has a basin arrangement with either continuously running water or a tap. Modern indoor drinking fountains may incorporate filters to remove impurities from the water and chillers to reduce its temperature. In some regional dialects, water fountains are referred to as bubblers. Water fountains are usually found in public places, like schools, rest areas and grocery stores. Many jurisdictions require water fountains to be wheelchair accessible (by sticking out horizontally from the wall), and to include an additional unit of a lower height for children and short adults. The design that this replaced often had one spout atop a refrigeration unit.

In modern fountains, the traditional gravitational pressure from an unseen reservoir at a higher level is not always practical. In many circumstances fountains obtain their water from a closed, recirculating system that must still be filled at the start from the local water supply system and also topped up through its life to offset the effects of evaporation. Allowance must also be made to handle overflow in the case of heavy rain.

The pressure that causes water to move through the fountain may be produced instead by a motor-driven (often-submersible electric) pump. “Static head” is useful to quantify this pressure.

 

 

A water filter, typically a media filter, removes particles from the water — this filter requires its own pump to force water through it and plumbing to remove the water from the pool to the filter and then back to the pool. The water may need chlorination or anti-algal treatment, or may use biological methods to filter and clean water.

The pumps, filter, electrical switch box and plumbing controls are often housed in a “plant room”. Low-voltage lighting, typically 12-volt direct current, is used to minimize electrical hazards. Lighting is often submerged and must be suitably designed. Floating fountains are also popular for ponds and lakes they consist of a float pump nozzle and water chamber.

Many civic fountains in public parks are commissioned in commemoration of either national or public figures.

 

 

There are also some limited fountain day celebrations. The University at Albany hosts an annual “Fountain Day,” a day on which the university community comes together to celebrate the arrival of spring and the near-end of the semester. Drawing large crowds, the fountain-centered event creates something akin to an urban beach.

A hydraulophone is a fountain that can be played as a musical instrument. These fountains are like woodwind instruments, but using water instead of air. The embouchure of the instrument occurs at the finger holes (referred to as “mouths”). Hydraulophones often have multiple “mouths”, so that a player can put each finger into a different mouth at the same time, in order to play chords, while independently manipulating each finger for separate and individual control of the embouchure of each note in a chord. A skilled hydraulist can slightly “bend” each note in order to play just intonation in any desired key, or to gently and fluidly vary intonation or temperament as a piece of music changes from one key to another.

There is a need for good water quality in contemporary fountains, regardless of their avowed intended use. Regardless of the fact that some fountains are designed and built not as bathing fountains, but are rather used simply as architectural decor, people will often drink from, bathe or wash their hands in any fountain. Additionally, fountain spray can contain legionella bacteria and has been linked to Legionnaires ‘disease outbreaks. Therefore, minimum water quality standards are necessary, regardless of intended use. Guidelines have been developed for control of legionella in ornamental fountains.

In theory, a freestanding water feature should not have a bather load, and consequently, many builders would not choose to install filters or sanitation devices. In reality, however, people will interact with ornamental water fountains in the most surprising ways. In Disneyland, for example, people have been reported to change their babies’ diapers and then wash their hands in the water fountain (thus adding unexpected bacteria and organics into the water).

In July 1997, an outbreak of cryptosporidiosis was connected to an ornamental fountain at the Minnesota Zoo, which did not have proper filtration and water treatment. Children played in fountains and swallowed water, and spurted the water out of their mouths to mimic the way nozzles in the fountain spurted the water. It was therefore necessary to put a fence around the fountain to keep people away.

 

 

In the United States fountain operators and owners are legally liable for failure to either fence-in fountains, or to properly filter, chlorinate or otherwise treat the water, if the fountains are not fenced in. If the water is unsafe, fences must be designed to keep people far enough away, so that they cannot touch the water, otherwise children get water on their hands, put their fingers into their mouths, and end up getting sick, thus subjecting owners and operators to legal liability.

If you are interested in adding a fountain to your home or office, Repairfinders.com is the perfect place for you. With many qualified professionals in your area, it will only take a couple of minutes to find the right person for you. Not only will a fountain bring you peace and entertainment it will also bring elegance to your home office.

 

 

Pest control refers to the regulation or management of a species defined as a pest, usually because it is perceived to be detrimental to a person’s health, the ecology or the economy.

Pest control is at least as old as agriculture, as there has always been a need to keep crops free from pests. In order to maximize food production, it is advantageous to protect crops from competing species of plants, as well as from herbivores competing with humans.

The conventional approach was probably the first to be employed, since it is comparatively easy to destroy weeds by burning them or plowing them under, and to kill larger competing herbivores, such as crows and other birds eating seeds. Techniques such as crop rotation, companion planting (also known as intercropping or mixed cropping), and the selective breeding of pest-resistant cultivars have a long history.

 

 

Many pests have only become a problem because of the direct actions of humans. Modifying these actions can often substantially reduce the pest problem. In the USA, raccoons caused a nuisance by tearing open refuse sacks. Many householders introduced bins with locking lids, which deterred the raccoons from visiting. Houseflies tend to accumulate wherever there is human activity and it is virtually a global phenomenon, especially where food or food waste is exposed. Similarly, seagulls have become pests at many seaside resorts. Tourists would often feed the birds with scraps of fish and chips, and before long, the birds would become dependent on this food source and act aggressively towards humans.

In the UK, following concern about animal welfare, humane pest control and deterrence is gaining ground through the use of animal psychology rather than destruction. For instance, with the urban Red Fox which territorial behavior is used against the animal, usually in conjunction with non-injurious chemical repellents.

Chemical pesticides date back 4,500 years, when the Sumerians used sulfur compounds as insecticides. The Rig Veda, which is about 4,000 years old, also mentions the use of poisonous plants for pest control. Ancient Chinese and Egyptian cultures are known to have used chemical pest controls. But it was only with the industrialization and mechanization of agriculture in the 18th and 19th century, and the introduction of the insecticides pyrethrum and derris that chemical pest control became widespread. In the 20th century, the discovery of several synthetic insecticides, such as DDT, and herbicides boosted this development. Chemical pest control is still the predominant type of pest control today, although its long-term effects led to a renewed interest in traditional and biological pest control towards the end of the 20th century.

Types of pest control

Organic pest and insect control

While chemical pesticides may kill insects effectively, some may also be toxic to human beings and lead to severe environmental degradation if their use is not properly managed. By comparison, natural pesticides, which are usually eco-friendly, are more conducive to environmental sustainability and more beneficial to public wellness. Many species have anti-insect properties but are non-toxic to humans, including Arisaema jacquemontii, which has been demonstrated to have an anti-cancer potency.

Elimination of breeding grounds

Proper waste management and drainage of still water, eliminates the breeding ground of many pest.

Garbage provides food and shelter for many unwanted organisms, as well as an area where still water might collect and be used as a breeding ground by mosquitoes. Communities that have proper garbage collection and disposal, have far less of a problem with rats, cockroaches, mosquito, flies, and other pest, than those that do not.

Open-air sewers are ample breeding ground for various pests as well. By building and maintaining a proper sewer system, this problem is eliminated.

 

 

Poisoned bait

Poisoned bait is a common method for controlling rat populations, however is not as effective when there are other food sources around, such as garbage. Poisoned meats have been used for centuries for killing off wolves, birds that were seen to threaten crops, and against other creatures.

Field burning

Traditionally, after a sugar cane harvest, the fields are all burned, to kill off any insects, or eggs, that might be in the fields.

Hunting

Historically, in some European countries, when stray dogs and cats became too numerous, local populations gathered together to round up all animals that did not appear to have an owner and kill them. In some nations, teams of rat catchers work at chasing rats from the field, and killing them with dogs and simple hand tools. Some communities in the past have employed a bounty system, where a town clerk will pay a set fee for every rat head brought in as proof of a rat killing.

Traps

Traps have been used for killing off mice found in houses, for killing wolves, and for capturing raccoons and stray cats and dogs for disposal by town officials.

Poison spray

Spraying poisons by planes, hand held units, or trucks that carry the spraying equipment, is a common method of pest control. Throughout the United States of America, towns often drive a town owned truck around once or twice a week to each street, spraying for mosquitoes. Crop dusters commonly fly over farmland and spray poison to kill off pest that would threaten the crops. Many find spraying poison around their yard, homes, or businesses, far more desirable than allowing insects to thrive there.

 

 

Destruction of infected plants

Forest services sometimes destroy all the trees in an area where some are infected with insects, if seen as necessary to prevent the insect species from spreading. Farms infested with certain insects, have been burned entirely, to prevent the pest from spreading elsewhere.

In conclusion, there are many ways to get rid of the vermin that plague our homes. However, the best way for the modern citizen to go about this would be to go to Repairfinders.com. On repairfinders.com, you will find many extermination companies in your area that will make sure that your home or business is pest free.

Hey, folks at home, it is your old pal Jack! Carpentry is a very interesting profession. It requires skill, creativity, honesty, and reliability. It is a great career choice for anyone who is willing to put the work into being good at this. It pays well, and once you take the proper classes, and get your certificates and license, you can make your own hours. So let us talk a little about this today. Carpenters are involved in many different kinds of construction, from the building of highways and bridges to the installation of kitchen cabinets. Carpenters construct, erect, install, and repair structures and fixtures made from wood and other materials.

Each carpentry task is somewhat different, but most involve the same basic steps. Working from blueprints or instructions from supervisors, carpenters first do the layout-measuring, marking, and arranging materials-in accordance with local building codes. They cut and shape wood, plastic, fiberglass, or drywall using hand and power tools, such as chisels, planes, saws, drills, and sanders. They then join the materials with nails, screws, staples, or adhesives. In the last step, carpenters do a final check of the accuracy of their work with levels, rules, plumb bobs, framing squares, and surveying equipment, and make any necessary adjustments.

 

When working with prefabricated components, such as stairs or wall panels, the carpenter’s task is somewhat simpler because it does not require as much layout work or the cutting and assembly of as many pieces. Prefabricated components are designed for easy and fast installation and generally can be installed in a single operation.

Some carpenters do many different carpentry tasks, while others specialize in one or two. Carpenters who remodel homes and other structures, for example, need a broad range of carpentry skills. As part of a single job, for example, they might frame walls and partitions, put in doors and windows, build stairs, install cabinets and molding, and complete many other tasks. Because these carpenters are so well trained, they often can switch from residential building to commercial construction or remodeling work, depending on which offers the best work opportunities.

Carpenters who work for large construction contractors or specialty contractors may perform only a few regular tasks, such as constructing wooden forms for pouring concrete, or erecting scaffolding. Some carpenters build tunnel bracing, or brattices, in underground passageways and mines to control the circulation of air through the passageways and to worksites. Others build concrete forms for tunnel, bridge, or sewer construction projects.

Carpenters employed outside the construction industry perform a variety of installation and maintenance work. They may replace panes of glass, ceiling tiles, and doors, as well as repair desks, cabinets, and other furniture. Depending on the employer, carpenters install partitions, doors, and windows; change locks; and repair broken furniture. In manufacturing firms, carpenters may assist in moving or installing machinery.

 

Work environment. As is true of other building trades, carpentry work is sometimes strenuous. Prolonged standing, climbing, bending, and kneeling often are necessary. Carpenters risk injury working with sharp or rough materials, using sharp tools and power equipment, and working in situations where they might slip or fall. Although many carpenters work indoors, those that work outdoors are subject to variable weather conditions.

Most carpenters work a standard 40 hour week. Hours may be longer during busy periods. Carpenters learn their trade through formal and informal training programs. Between 3 and 4 years of both on-the-job training and classroom, instruction usually is needed to become a skilled carpenter. There are a number of ways to train, but a more formal training program often improves job opportunities.

Education and training. Learning to be a carpenter can start in high school. Classes in English, algebra, geometry, physics, mechanical drawing, blueprint reading, and general shop will prepare students for the further training they will need.

 

After high school, there are a number of different ways to obtain the necessary training. Some people get a job as a carpenter’s helper, assisting workers that are more experienced. At the same time, the helper might attend a trade or vocational school, or community college to receive further trade-related training and eventually become a carpenter.

Some employers offer employees formal apprenticeships. These programs combine on-the-job training with related classroom instruction. Apprentices usually must be at least 18 years old and meet local requirements. Apprenticeship programs usually last 3 to 4 years, but length varies with the apprentice’s skill.

On the job, apprentices learn elementary structural design and become familiar with common carpentry jobs, such as layout, form building, rough framing, and outside and inside finishing. They also learn to use the tools, machines, equipment, and materials of the trade. In the classroom, apprentices learn safety, first aid, blueprint reading, freehand sketching, basic mathematics, and various carpentry techniques. Both in the classroom and on the job, they learn the relationship between carpentry and the other building trades.

The number of apprenticeship programs is limited, however, so only a small proportion of carpenters learn their trade through these programs. Commercial and industrial building contractors with union membership offer most apprenticeships.

Some people who are interested in carpentry careers choose to get their classroom training before seeking a job. There are a number of public and private vocational-technical schools and training academies affiliated with unions and contractors that offer training to become a carpenter. Employers often look favorably upon these students and usually start them at a higher level than those without the training.

 

 

Other qualifications. Carpenters need manual dexterity, eye-hand coordination, physical fitness, and a good sense of balance. The ability to solve arithmetic problems quickly and accurately also is required. In addition, military service or a good work history is viewed favorably by employers.

Certification and advancement. Carpenters who complete formal apprenticeship programs receive certification as journeypersons. Some carpenters earn other certifications in scaffold building, high torque bolting, or pump work. These certifications prove that carpenters are able to perform these tasks, which can lead to additional responsibilities.

Carpenters usually have more opportunities than most other construction workers do to become general construction supervisors because carpenters are exposed to the entire construction process. For those who would like to advance, it is increasingly important to be able to communicate in both English and Spanish in order to relay instructions and safety precautions to workers; Spanish-speaking workers make up a large part of the construction workforce in many areas. Carpenters may advance to carpentry supervisor or general construction supervisor positions. Others may become independent contractors. Supervisors and contractors need good communication skills to deal with clients and subcontractors. They should be able to identify and estimate the quantity of materials needed to complete a job and accurately estimate how long a job will take to complete and what it will cost. Average job growth, coupled with replacement needs, create a large number of openings each year. Job opportunities should be best for those with the most training and skills.

Employment change. Employment of carpenters is expected to increase by 10 percent during the 2006-16 decade, about as fast as the average for all occupations. The need for carpenters should grow as construction activity increases in response to demand for new housing and office and retail space, and for modernizing and expanding schools and industrial plants. A strong home remodeling market also will create demand for carpenters. Moreover, construction of roads and bridges as well as restaurants, hotels, and other businesses will increase the demand for carpenters in the coming decade.

Some of the demand for carpenters, however, will be offset by expected productivity gains resulting from the increasing use of prefabricated components and improved fasteners and tools. Prefabricated wall panels, roof assemblies, and stairs, as well as prehung doors and windows can be installed very quickly. Instead of having to be built on the worksite, prefabricated walls, partitions, and stairs can be lifted into place in one operation; beams and, in some cases, entire roof assemblies, are lifted into place using a crane. As prefabricated components become more standardized, builders will use them more often. In addition, improved adhesives are reducing the time needed to join materials, and lightweight, cordless, and pneumatic tools-such as nailers and drills-will all continue to make carpenters more productive. New and improved tools, equipment, techniques, and materials also have made carpenters more versatile, allowing them to perform more carpentry tasks.

 

Job prospects. Job opportunities should be best for those with the most training and skills. Job growth and replacement needs for those who leave the occupation create a large number of openings each year. Many people with limited skills take jobs as carpenters but eventually leave the occupation because they dislike the work or cannot find steady employment.

Carpenters with all-around skills will have better opportunities for steady work than carpenters who can perform only a few relatively simple, routine tasks. Carpenters can experience periods of unemployment because of the short-term nature of many construction projects, winter slowdowns in construction activity in northern areas, and the cyclical nature of the construction industry.

Employment of carpenters, like that of many other construction workers, is sensitive to the fluctuations of the economy. Workers in these trades may experience periods of unemployment when the overall level of construction falls. On the other hand, shortages of these workers may occur in some areas during peak periods of building activity.

Job opportunities for carpenters also vary by geographic area. Construction activity parallels the movement of people and businesses and reflects differences in local economic conditions. The areas with the largest population increases will also provide the best opportunities for jobs as carpenters and for apprenticeships for people seeking to become carpenters. Therefore, as you can see it takes a lot of skill to become a carpenter. The only place to find the best in the field is at Repairfinders.com. We have the best in the business listed and you could never go wrong. Do not believe me check it out for yourself!

The television set has been and will continue to be the hub of the American home entertainment system for some time. Emerging technologies and expanded programming have driven consumers to purchase television sets with more features and at a higher cost. Knowing how to make a few basic repairs to your own television set can save you the time and money of consulting a professional over a simple problem, and even protect you from the unnecessary purchase of a new set.

However, home repair enthusiasts, experienced or otherwise, should note that television sets contain dangerously high voltages (more than 30,000) and even “quick fixes” should not be handled lightly. When making any repairs, wear safety glasses and work gloves at all times.

One of the most common malfunctions in cable televisions is a blurred (or snowy) picture. Most often, a flaw in the coaxial cable connecting the TV (or VCR) to the cable antenna causes this: the wiring itself may be flawed or the fitting may be loose. To determine if this is the case, turn the television on and wiggle the coaxial cable where it enters the television and where it enters the cable output. If the snow on the screen wavers (gets better or worse), you know there is a problem with the cable. In addition, you can try using the same cable on another television in your house. If it produces a snowy picture there also, you know there is a problem with that cable. Replacing the cable is inexpensive and easy: they can be found in the electronics section of most department stores and hardware stores in a variety of lengths and colors. Be sure to properly dispose of the flawed cable.

Another common malfunction that occurs in television sets is blotches of color, which may be particularly apparent around the edges of the screen. This can happen if the television screen becomes magnetized, which will occur if the television is placed near other electronic equipment, such as stereo speakers. While most televisions contain a circuit that will automatically de-magnetize the screen, this circuit may be damaged or otherwise malfunctioning. To de-magnetize the television yourself, you will need to purchase a strong magnetic coil: these can be found at most hardware stores. Hold the coil in the upper left hand corner, a few inches away from the screen (a rainbow pattern should appear on the screen). Making small circular motions move the coil around the screen, (the rainbow pattern should fluctuate). Increase the size of your circular motions until you have covered the entire screen and then slowly back away from the television set, continuing to make circular motions. When the coil loses contact with the screen, the blotches of color should be gone. In order to successfully de-magnetize the set, you may need to repeat these steps several times.

 

 

Replacing a television speaker that emits static noise can be simple, but requires caution because it entails removing the back cover of the television set, exposing the high voltage lead that runs into the top part of the picture tube. Even if the television is unplugged, the tube can shock you: do not touch it in any way. You will also be required to purchase a replacement speaker, which needs to match your current speaker in impedance, which will usually be indicated on the magnet. Begin by unplugging your television and laying it, screen down, on a soft surface. Remove any screws (usually Phillips head) from the back of the television shell. Then, pull back on the cover; if you feel resistance, you may have missed a screw or the cover may have snagged on one of the set’s internal wires. Carefully remove these obstacles and set the cover aside. Identify the malfunctioning speaker (whichever one usually emits static noise), and replace it with the new one. Reattach the speaker in the same manner the old one was attached. Replace the television cover and attach with screws. Important: During this process, it is very important to make sure none of the internal wiring of the television is jarred, twisted, or broken. Any damage to these components can irrevocably impair the function of the set.

If your television set has, a tendency to shut off randomly, it is probably overheating. Permanently remove any objects placed on or too close to the television’s ventilation slats. Use a small vacuum attachment to remove any dust that has built up there. This should successfully prevent your television from randomly shutting off again.

 

 

These four techniques will cure 50% of the problems that ail your television set, saving you time and money. If using these techniques does not work for you or if you feel unsure in performing any of them, a professional television repairperson should be contacted. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. If not, it may be time to shop around for a newer model.  This is a wonderful way to fix your TV yourself, but if you are like me and don’t have much time on your hands, or you just don’t think you can do it. Find a professional on Repairfinders.com with dozens of listings in your area, finding the right man for the job will be a breeze!

As most of you all already know, I enjoy informing you about many different aspects of the repair/skill/labor industry. I do this because I think it is only fair that everyone should know what is going on out there. Today I want to talk about construction. Many people do not know much about constructors, except that they build things. Well I can tell you they do more than just build things.

In general, there are three types of construction:

1. Building construction
2. Heavy/highway construction
3. Industrial construction

Each type of construction project requires a unique team to plan, design, construct, and maintain the project.

Building construction

Building construction is the process of adding structure to real property. The vast majority of building construction projects are small renovations, such as an addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, and design team for the entire project. However, all building construction projects include some elements in common - design, financial, and legal considerations. Many projects of varying sizes reach undesirable results, such as structural collapse, cost overruns, and/or litigation reason; those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome.

Building construction is procured privately or publicly utilizing various delivery methodologies, including hard bid, negotiated price, traditional, management contracting, construction management-at-risk, design & build and design-build bridging.

Procurement

Procurement describes the merging of activities undertaken by the client to obtain a building. There are many different methods of construction procurement; however, the three most common types of procurement are:

Traditional (Design-bid-build)

Design and Build

Management Contracting

Traditional

This the most common method of construction procurement and is well established and recognized. In this arrangement, the architect or engineer acts as the project coordinator. His or her role is to design the works, prepare the specifications and produce construction drawings, administer the contract, tender the works, and manage the works from inception to completion. There are direct contractual links between the architect’s client and the main contractor. Any subcontractor will have a direct contractual relationship with the main contractor.

Design and build

This approach has become more common in recent years and includes an entire completed package, including fixtures, fittings and equipment where necessary, to produce a completed fully functional building. In some cases, the Design and Build (D & B) package can also include finding the site, arranging funding and applying for all necessary statutory consents.

The owner produces a list of requirements for a project, giving an overall view of the project’s goals. Several D&B contractors present different ideas about how to accomplish these goals. The owner selects the ideas he likes best and hires the appropriate contractor. Often, it is not just one contractor, but a consortium of several contractors working together. Once a contractor (or consortium/consortia) has been hired, they begin building the first phase of the project. As they build phase 1, they design phase 2. This is in contrast to a design-bid-build contract, where the project is completely designed by the owner, then bid on, then completed.

Kent Hansen, director of engineering for the National Asphalt Pavement Association (NAPA), pointed out that state departments of transportation (DOTs) usually use design build contracts as a way of getting projects done when states do not have the resources. In DOTs, design build contracts are usually used for very large projects.

Management procurement systems

In this arrangement, the client plays an active role in the procurement system by entering into separate contracts with the designer (architect or engineer), the construction manager, and individual trade contractors. The client takes on the contractual role, while the construction or project manager provides the active role of managing the separate trade contracts, and ensuring that they all work smoothly and effectively together.

Management procurement systems are often used to speed up the procurement processes, allow the client greater flexibility in design variation throughout the contract, the ability to appoint individual work contractors, separate contractual responsibility on each individual throughout the contract, and to provide greater client control.

Residential construction

Residential construction practices, technologies, and resources must conform to local building authority regulations and codes of practice. Materials readily available in the area generally dictate the construction materials used (e.g. brick versus stone, versus timber). Cost of construction on a per square meter (or per square foot) basis for houses can vary dramatically based on site conditions, local regulations, economies of scale (custom designed homes are always more expensive to build) and the availability of skilled trades people. As residential (as well as all other types of construction) can generate a lot of waste, careful planning again is needed here.

Heavy/civil construction

Heavy/Civil construction is the process-adding infrastructure to our built environment. Owners of these projects are usually government agencies, either at the national or local level. As in building construction, heavy/civil construction has design, financial, and legal considerations, however these projects are not usually undertaken for-profit, but to service the public interest. However, heavy/civil construction projects are also undertaken by large private corporations, including, among others, golf courses, harbors, power companies, railroads, and mines, who undertake the construction of access roads, dams, railroads, general site grading, and massive earthwork projects. As in building construction, the owner will assemble a team to create an overall plan to ensure that the goals of the project are met.

As you can see, construction work is a very difficult job (but of course, we knew that already). The key point that I am trying to make is that, when someone is working for you, you want for him or her to do the best. Where can you find the best to get the job done? Mmmhmmm, I knew you knew. Repairfinders.com. It is the only place where you can find the very best in the business, in your neighborhood.

Do it yourself Auto bodywork was taken from: http://www.helium.com/items/1086080-auto-body-repair-and-repainting. It is a brief overview of how to do auto body work, yourself. It takes a lot of time, patience, and will power to get this done. Not everyone was made to do this on their own, so if like me you slightly cringe to the thought of having to fix your car up yourself do not worry. There is hope for us on repairfinders.com!

If one were to consider in doing-it-yourself auto body repair, you should have some basic interest in working with metal sheets. To do this kind of metal working the basic tools needed to repair dents and small rust holes are:

1. Ball peen Hammer

2. Rubber Mallet

3. Metal dolly

4. Tinsmith’s Spoons

5. Wire brush, steel or bronze

 

 

Working on dents does not necessarily mean hammering the body part to its original shape. All that is needed is to work back the dent to about at least 1/8 of an inch to its original shape. Making it shape to almost original will be completed by applying body filler and putty. In the process of gently hammering back the dent, paint will either chip-off or crack. It will be necessary to do the following:

1. Sandpaper away the paint and surrounding areas up to about 2 inches away from the exposed metal. Try to “feather-off” the paint meeting the bare metal to allow proper adherence of the body filler to be applied. Use 120 grit sand paper for this. Wet sanding is advisable then wipe thoroughly dry.

2. Dab the exposed metal with rubbing alcohol or anti-rust compound. Make sure to avoid applying it on the painted area.

3. If rust is evident, use steel brush or bronze brush to remove, if possible, all traces of rust.

4. It is at your option to thinly hand paint with primer the bare metal if it is not larger than the size of your palm.

5. Let the area dry completely before applying body filler. If you are a beginner, most body fillers come in two parts. The hardener, usually in a small plastic tube, is the catalyst to harden the compound. Use it sparingly because using too much will cause the filler to harden real fast in a couple of minutes. Mix the compound well and apply with gentle pressure in one direction to fill the depression on the body. Apply the filler close to the nearest undamaged paint.

6. After the body filler has hardened and dried wet sand gently with 320 grit sand paper to follow the contour of the body. Make sure that the body filler feathers where it meets with the original paint. Feathering means there is no ridge felt when you run your fingertips on where the ends meet. It takes time to be accurately sensitive to feel this difference to the touch. Running over the ends several times with your closed palm and fingertips will give you the “feel”.

7. To complete the filling, apply very thinly, glazing putting over the body filler to cover slight imperfections and pores. Again wet sand with 600 grit sand paper the entire area that you worked on. Overlap slightly sanding on the original paint. Let dry completely.

8. Apply primer surfacer spray (available in aerosol cans) with a color closest to your original paint. After the primer has completely dried, wet sand again with used 600 grit sand paper or new 800 grit sand paper. Wipe and let dry completely.

9. Apply paint color of your car from four to six coats letting each coat dry completely before applying the next coat. If the color code of your paint is available, normally you can get them too in aerosol cans.

10. After the final coat has completely dried, wet sand the finish very lightly with 1000 grit sand paper.

11. To bring out the sheen and luster of the paint job and blend it to the original, rub the entire work with fine rubbing compound with consistent light pressure strokes. Wipe off the repaired area and buff with circular motion.

Tips on Spray Painting:

NOTE: Know if your original paint is enamel, lacquer or acrylic. NEVER apply acrylic over enamel or lacquer finish. Enamel or lacquer over acrylic is just fine.

Mask off areas not to be painted.

Hold the spray about eight to ten inches away from the area.

Spraying motion should be back and forth overlapping each stroke by about 1/3 of its width.

Spray stroke speed should be close to 1 foot per second but not faster.

Release trigger or button away and past the work area if you need to stop or pause.

If a mistake or error was made and defect shows on paint applied, let dry completely then wet sand area with 1000 grit sand paper. When dry, resume painting finish.

To add shine and luster protect color, you can spray a clear coat to the last color coat.

Hello folks at home. I hope yall are having a wonderful day, wherever you may be today. I was thinking about children’s today, and how they all want to be musicians, actors, and fashion & graphic designers. But what I would like to know is whatever happened to the days, when kids wanted to be like their pa’s and become plumbers, engineers, carpenters, and such? Today let us talk about general contractors and so on; it is a nice aspiration for anyone who wants to live a comfortable life.

 

General contractors coordinate and supervise the work at construction sites from early development to final product. They own the contracting firms in charge of construction, or they may be salaried employees of property owners and developers. Sometimes they have different titles, such as construction managers or project engineers. While some general contractors undertake many kinds of work, most of them specialize in one type and size of construction project. Residential contractors may oversee some commercial buildings, for instance, but they rarely take on large-scale public-works projects, such as bridges, sewage systems, and industrial sites.

 

 

Before contractors begin a project, they must submit a bid or price quote to the individual, company, or government agency that will pay for it. To make an accurate bid, contractors study the building plans and specifications while keeping in mind material, labor, and safety considerations. They may hire a cost estimator to do this job. The lowest bid is usually, but not always, accepted. Other factors, such as the quality of a contractor’s past work, may be taken into account. Construction projects are usually a series of tasks, each completed by a different subcontractor. The bulldozer operators clear and level the land, so the structural steelworkers or the carpenters can put up the skeleton of the building. General contractors hire or supervise the hiring of the subcontractors who do each of the many tasks. Contractors must communicate well because they need to motivate many different types of people.

 

Contractors either own or rent the equipment needed for the job. They contact companies that supply concrete, steel, electrical equipment, lumber, and other building materials to arrange shipments, and they get the necessary permits and licenses for construction and see that building codes and safety regulations are followed. At all steps in the construction, contractors track and control expenditures. Depending on the job, contractors may have several people to help with management details. They may hire estimators to help prepare bids, expediters to oversee material shipments, various job supervisors, office staff, and others. However, contractors shoulder the full responsibility and risk involved. On repairfinders.com, you can find general contractors, in your area, so if you need a job done they can do it for you!

Hey folks at home, its Jack here. And today were gonna discuss landscaping. “Landscaping.” Sounds rather impressive, doesn’t it? You could spend years studying all the ideas in the field of garden or landscape design. But what about if you want to give your lawn a makeover, or you wish to tinker with designing your own garden? If you need to spruce up the landscape design of a house that you are about to sell, or if you simply want to enjoy an enhanced beauty in the privacy of your backyard, you could profit from a straightforward, no-nonsense look at the ideas behind designing a garden, supplemented with hands-on project guides.

Whenever you put something together yourself, you are engaged in designing, however humble the project. Sometimes we take our designing skills for granted, because what we are putting together is so commonplace for us that we are no longer conscious of the designing process. For instance, you are employing designing techniques when you compose a letter to send to somebody. Your basic “elements” to accomplish such a task include vocabulary, spelling and grammar. Somewhat more elements that are complex or “principles” build directly on the basic elements. Letter-writing principles include conveying your ideas clearly and coming across as a courteous, intelligent individual. Your success with these principles will largely determine whether your letter achieves its ultimate objective.

And that is how it is with landscape design. Do-it-yourselfers must first learn the basic designing elements that underline the discipline of landscape design. These fundamental elements will then serve as building blocks for learning and implementing the more advanced principles for designing a garden in the backyard. These tried and true principles are the cornerstones of the world’s picture-perfect gardens.

The basic elements of landscape design are Color (as defined by color theory), Form, Line, Scale, and Texture. These five elements must be considered in designing both the hardscape and softscape of your property, the latter consisting mainly of gardens, lawns, shrubs and trees.
