A reciprocating saw is a machine-powered saw with a cutting action that is achieved by a push and pull motion of the blade. The type of power tool is most often used in demolition work and construction work.
Some refer to this saw like the reciprocating saw, or hognose as it has a large blade that looks much like the jigsaw and its handle is oriented in a way so the saw can be comfortably on vertical surfaces.
The most common design for the reciprocating saw includes afoot by the base of the blade much like the jigsaw. When you use the reciprocating saw, you will rest its foot on the surface of the area where you are cutting so that the blade will push away from or pull it towards the cut as the blade goes through its movement.
There are a variety of designs and they vary according to the saws speed, and power. The designs also differ from the less powerful portable version to the handheld models that resemble the cordless drill, all the way to the corded models designed for the demolition work or construction site jobs. Modern reciprocating saws have variable speed controlled through a trigger or through a dial.
Another feature of the newer models is how they can be used in orbital action. Through this action, the saw oscillates the traversed reciprocation in an up and down motion, which causes the tip of the blade to create an oval pattern, back and forth, as well as up and down. The saw is primarily used for wood and allows for quick cuts. Popular uses for the reciprocating saw are with construction workers, window fitters, and many emergency rescues services.
Accessories and variants are available for many specialized uses such as long blades for cutting large pipes and clamps. The power tool known as the circular saw uses an abrasive or toothed disc or blade to make different cuts in material with a rotary motion that spins around an arbor. This is one of those power tools with a rotating blade used to cut a variety of materials such as metal, plastic, masonry, and wood.
The blades for the circular saw are specially designed depending on the material you intend to cut. The cuts this tool makes are considered cross-cuts, rip cuts, or a combination of both. The circular saw is commonly powered by electricity, but some models are powered by an engine or hydraulic motor to allow it to be fastened to heavy equipment so the need for separate energy sources is eliminated.
The material to be cut by a circular saw is typically secured in a vise or held by a clamp, so the saw can advance across it slowly. As each tooth in the blade hits the material, it makes a small chip in it. The teeth are what guides the chip out of the material, to it cannot bind the blade. Some of the circular saw features are that it cuts with teeth on the edge of an abrasive wheel or metal blade.
It will make narrow cuts that make a relatively smooth surface finish, and the cuts are accurate and relatively straight. The circular saw a lot of times leaves burrs on the cut edge of plastic and metal, which will need sandpaper to clean off.
A power tool saw, the miter saw, also known as the drop saw is used to make accurate crosscuts in your project at the desired angle. This useful saw is used for the cutting of trim and molding and is relatively portable and small, which comes with blades ranging from eight to twelve inches. The miter saw makes its cuts by pulling a circular saw blade onto your project in a controlled, short motion. Your project is typically held against what is called a fence, so you are able to achieve a precise cutting angle between the plane of the longest workpiece and the plane of the blade.
Standardly this angle is set to ninety degrees. This saw has the main feature that distinguishes it from other saws which are the miter index.
Most miter saws can create precise one-degree changes to the miter index, some models make it possible to stop and allow the miter index to be set to common angles such as forty-five, thirty, or fifteen. A band saw is a fixed power tool that has a sharp, long blade that has a continuous band of toothed metal that is stretched between two or more wheels and cuts materials.
These saws are principally used in lumbering, metalworking, and woodworking, but are able to cut a variety of materials. An advantage with the band saw over other models of power tool saws is its uniform cutting action that can evenly distribute its tooth load. The smallest radius of the curve on a band saw is determined by the width of the band and its kerf. Most of the band saws you will see have two wheels that rotate in the same plane.
One of the wheels is typically powered, however, some have three and sometimes four that will distribute the load. Blades of the band saw are available in different sizes and pitch of the teeth so that the machine tool can become versatile and perform cuts in a variety of materials including plastic and wood.
Most of the band saws on the market are powered by an electric motor, and the first models that used line shafts are now considered antiques. You can find a band saw in most residential workshops or garages and they are often used in light industry to cut through plastic, wood, or metals. Many owners of these light-duty projects leave a general-purpose blade in the saw, but the blades are easily switched out when you need to cut through different materials.
See what cool things you can make with a band saw:. A table saw is a fixed power tool sometimes referred to as a bench saw or sawbench and is considered a woodworking tool.
These saws have a circular saw blade mounted on what is called its arbor. An arbor is a round object that materials are pressed against so they can be shaped or forged. A table saw is powered by an electric motor, and has a blade that protrudes through the top of the table. With this design, the material you are cutting has the support of the tabletop while you make your cuts.
The depth of the cut you can make is determined by how you set your blade in an up or down position. If you have the blade positioned higher, protruding above the tabletop, you will get a deeper cut. The chain saw is a mechanical, portable saw which uses a set of teeth that are attached to a rotating chain. The chain runs along a guide bar and the machine is used for cutting projects such as pruning, bucking, limbing, or cutting down trees.
These cutting projects are often done for creating firebreaks during wildland fire containments, or for homeowners to harvest firewood for heating their homes. Chainsaws were designed with a chain and bar combination and are powerful tools that can also be used for chainsaw mills or in creating chainsaw art. Some special models of the chainsaw have the ability to cut through concrete, and there are some versions that can be used to cut through the ice for creating ice sculptures.
The engine of a chainsaw is traditionally either an internal combustion engine or the two-stroke gasoline version. The combustion engines are supplied either through an electronically adjustable carburetor or a traditional carburetor.
If it is constructed with a traditional carburetor, it needs to be adjusted when operating in low or high altitudes and the fuel, the oil-to-gasoline ratios have to be adjusted for proper operations. The engines on the chainsaw have been designed so the machines can be operated in different positions to reach those awkward types of cuts needed to be done.
The chainsaw can be rotated upside down or tilted at a ninety-degree angle. When chainsaws first hit the market, the engines would kill if the machine was not held straight. These tabs are chromium-plated with angular or curved corners and are extremely sharp.
Chains are available in different gauges and pitches, and built into each tooth of the chain is a gauge that goes ahead of the tooth to limit the depth of cut. In the line of power tools, the biscuit joiner, or plate joiner is a woodworking tool most often used to join two pieces of wood.
The biscuit joiner operates with a small circular saw blade that cuts a crescent-shaped hole, or mouth, in the opposite edge of two pieces of wood. The glue-covered biscuit is then inserted into the slot and the two boards get clamped together. As the glue expands, the biscuit improves the bond of the wood. The biscuit joiner is primarily used to join plywood, medium-density fiberboard, or particleboard.
It can be used with solid wood, as well to replace tenon and mortise joints which can make them almost as strong. This power tool can also align pieces of wood when you need them to join edge-to-edge to create a wider panel.
Biscuit joiners can be used to align workpieces when you need a ninety-degree angle between your workpieces and provide a quick way to achieve a perfectly flush joint while you reinforce a joint. These machines typically have an adjustable fence, so you are able to set an angle for putting together mitered pieces.
There are special types of biscuit joiners available including ones with removable panels, metal connectors, and hinged models, which make these machines more portable and flexible. The body of the biscuit joiner has a blade that is spring-loaded, and when in its normal position can be retracted.
To use the biscuit joiner, you align the machine and using firm pressure, you push the body forward against its blade.
This motion is what makes the cut, and the waste material gets blown out of a slot on the right-hand side of the base. The depth of the cut you make with the biscuit joiner can be altered with an adjustable stop, and you can rotate the base through ninety-degree turns to alter the offset of the base. Some models of this power tool allow you to cut angles other than at ninety-degrees, which will greatly speed up your assembly of projects such as making cabinets.
An angle grinder is sometimes called a disc grinder or side grinder and is a portable hand power tool. It is used to grind and polish, and although designed as a tool for rigid abrasive discs, it has an interchangeable source of power that allows for a wide variety of attachments and cutters.
The motor on the angle grinder drives a right-angled gear head that has an abrasive disc, or a thin cut-off disc, both of which can be replaced when worn out. Typically, the angle grinder has an adjustable guard as well as a side-handle so you can use it as a two-handed operation.
Some angle grinders, depending on how fast they operate, can also be used as a sander by attaching a sanding disc and a disc or backing pad. A backing system is normally made from hard plastic, medium-hard rubber, or phenolic resin depending on how flexible you want your project.
Angle grinders are standard equipment on construction sites, metal fabrication shops, and are commonly used in machine shops along with bench grinders, and die grinders. This power tool is able to remove excess material from your project. It has a number of discs you will be able to use in a multitude of tasks. One of the best-known uses for the angle grinder is for emergency rescues.
You will also see them in use at service garages, workshops, and auto body repair shops. When choosing an angle grinder, you want to make sure it has the right disc size and has a powerful motor. You will also want to check the power source, RPMs, and arbor size.
The disc size and power increase together, and the disc sizes, measured in either millimeters or inches will run from four inches up to twelve. You will want to ensure you choose the right disc size for the projects you will do, and it has the power to get through them. The larger version of these grinders are mounted on a pedestal which is often bolted to the floor, or sometimes sits on rubber feet. The bench grinder is most often used to hand grind cutting tools or to perform other rough grinding projects.
The bench grinder can be used to cut or sharpen tools such as chisels, drill bits, tool bits, and gouges. It can also be used to shape metal before it is fitted or welded. With the wire brush wheel that acts as a buffer and which can be interchanged on the grinder with the grinder wheels, it can polish your workpieces.
Typical wheels on the bench grinder are vitreous-bond wheels. A vitreous-bond wheel is made from green silicon carbide abrasive. These work best, but do have a tendency to crack. The grinding wheels when attached to the bench grinder, should not be used for grinding softer metals such as aluminum. Soft metal can become lodged in the pores of the wheel, which will then expand with the heat of grinding. These metal pieces that have become lodged in the pores can later dislodge from the wheel and cause serious injury.
You should never grind on the disk-shaped side of the bench grinder wheel as this side is designed for grinding periphery only.
Grinding of any other nature on this side increases the risk of a wheel explosion. With the bench grinder, you will need to keep the tool rest tight and with two to three inches from the wheel. This placement will prevent your workpiece from slipping down between the tool rest and wheel. This placement will also catch any stray sparks. A special kind of vacuum which is most often used in woodworking and construction is known as the shop vac.
The shop vac is a high-powered motor unit with incredible suction that can pick up chunks of building site materials, debris, and dirt. These vacuums feature a large, tough hose and an extra big canister to hold the debris it picks up. These may be screwed into plastic anchors. Usually the manufacturer will send some plastic anchors. With a drill bit slightly smaller than the anchor, drill the holes for the new base. Wire The New Thermostat Using the paper that you wrote the wire colors on, connect the wires accordingly to the new thermostat.
Remember, each color goes on only one terminal screw. Attach The New Thermostat Now attach the new thermostat to the base and install the cover. Depending on the model, this may be mounted with screws. Turn Power On The final step is to turn the power back on and test the thermostat. Check to see if the thermostat is functioning properly. As winter approaches and the temperature plummets, the need for heat in your home becomes more important.
Portable and fixed heating are used to heat the home. These heating and safety tips will keep the winter months both warm and safe for you and your family! Gas Space Heater Tips Both gas and electric space heaters are a great source of additional heat in a home when you want to heat just a room or two. Top Three Types Of Space Heaters Space heaters are an excellent way of warming up an individual room without turning up the thermostat to the entire house. These small portable heaters can be placed most anywhere in the house that flammable materials are not present.
What Is A Furnace Switch? Furnace disconnects sometimes incorporate both a fuse and a switch to disconnect power from a gas furnace. The fuse screws into the fuse socket and is covered by a metal lid that is hinged on one side. Danger of Overloading Electrical Circuits With Portable Electric Heaters As the extreme cold snap takes a grip on your area, many times people are tempted to plug in portable electric heaters to add a little extra heat to rooms.
The problems start when you connect too many heaters to the same circuit and cause a circuit overload. By overloading the circuit, the electrical wires and connection will heat up and trip the circuit breaker or blow the fuse it is connected to.
Obviously there is a problem, but too often, people will just go and reset the breaker or change the fuse. How To Wire a Baseboard Heater Thermostat Baseboard heater thermostats are a great way of regulating the temperature of a room. Baseboard heaters can have the thermostats connected directly to the heater or mounted externally on a wall. Either way, they turn the power on and off to the unit, like a switch turns a light on and off. What is a Baseboard Heater?
Baseboard heaters can add supplemental heat to a room that is drafty or colder than other rooms. They come in different lengths to accommodate almost any room or application. These electric heaters radiate heat into a room and are placed on the outside wall of a home, usually the coldest wall. Baseboard heaters are also used in areas like bathrooms in garages where a little heat would be nice. This includes the total living area of the room to be heated.
Remember that if you are in a particularly cold area of the country, check with your local inspector or heating and cooling contractor for correct sizing for you area. According to NEC article It delivers open neutral protection to safeguard plant personnel against the risk of electrical shock, while also protecting the connected apparatus against damage from short circuits and current overload.
In addition to use in hazardous locations, it also meets UL and CSA requirements for non-hazardous locations, including marinas, docks and other wet applications. A highly visible pilot light indicates the GFCI is engaged and that the receptacle is ready for use. Everybody is using some electrical equipments each day and thus electrical safety is something we need to pay attention to.
What are the safeguard procedures that could be obeyed to guarantee the electrical safety? Some guidance will be provided here and hope it will help you out. Replace or repair damaged equipment right away. Nails and staples can damage cords resulting shock hazards and fire. If you replace a fuse with a larger size, you are possibly to cause over currents in the wiring and thus a fire.
You may be need to install GFCI,as they will halt the electrical circuit before a current becomes sufficient to cause injury or even death. Also, never block access to circuit breakers or fuse boxes and do not touch a person or electrical apparatus in the event of an electrical accident.
You should cut off the current first. Electrical safety is easy. It should be kept in mind that everybody electricity shall take precautions to avoid injuries. Be careful and be safe. When you need a jump to start your car, it is time for you to change your battery.
