Power Tools

OSHA 3080 defines a power tool as any tool requiring external electrical, pneumatic, or chemical power to function.



Main Article : Bandsaw
Delta band saw.

A bandsaw (also written band saw) is a saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw. Additionally since the blade is pulling the material into the table it is unlikely there will be kickback or ricochets. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of size and tooth pitch (teeth per inch, or TPI) which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.

Circular Saw

Main Article : Circular Saw
Circular saw.

A circular saw is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other common forms of circular saws. "Skil saw" has become a generic trademark for conventional hand-held circular saws. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for making rip-cuts, cross-cuts, or a combination of both.

Miter Saw

Main Article : Miter Saw
Miter saw.

A power miter saw, also known as a drop saw or chop saw, is a power tool used to make a quick, accurate crosscut in a workpiece at a selected angle. Commonly used for cutting of molding and trim. Most miter saws are relatively small and portable, with common blade sizes ranging from eight to twelve inches. The miter saw makes cuts by pulling a spinning circular saw blade down onto a workpiece in a short, controlled motion. The workpiece is typically held against a fence, which provides a precise cutting angle between the plane of the blade and the plane of the longest workpiece edge. In standard position, this angle is fixed at 90°. A primary distinguishing feature of the miter saw is the miter index that allows the angle of the blade to be changed relative to the fence. While most miter saws enable precise one-degree incremental changes to the miter index, many also provide "stops" that allow the miter index to be quickly set to common angles (such as 15°, 22.5°, 30°, and 45°). Compound-Miter saws add the ability to rotate the blade head at a range of angles from the board allowing you to enter the wood at an angle other than 90 degrees. Creates a ramp angled cut into the side of the wood. Allows for more complex cuts and is commonly used in trim work for homes.

Panel Saw

Main Article : Panel Saw
Panel saw.

The panel saw is any type of circular sawing machine with a sliding table or saw blade that crosscuts sheets into sized parts. The Idea Shop panel saw is a vertical unit with a sliding saw blade. This is especially useful for cutting down large standard 4' x 8' sheets of plywood, melamine, acrylic or cardboard. The saw normally operates in the vertical cutting direction, however the blade can be rotated to rip long steps from sheet material. Many circular saw blades are available to cut a variety of materials from wood to metals. Because of guards the panel saw is a much safer alternative to the table saw for making straight cuts, especially on large stock materials. The size of the stock normally requires two poeple to load the material safely into the machine.

Drill Press

Main Article :Drill Press
Drill press.

Drilling machines, or drill presses, are primarily used to drill or enlarge a cylindrical hole in a workpiece or part. The chief operation performed on the drill press is drilling, but other possible operations include: reaming, countersinking, counterboring, and tapping.

Sanders / Grinders

Belt/Disc Sander

Safety Instructions:

1. Always wear eye protection when using a belt/disc sander.

2. Remove ties, ring, watch and other jewelry, and roll up sleeves before using the belt/disc sander.

3. Make all adjustment on the belt/disc sander with the power OFF.

4. Make sure the sand belt or disc is not torn or loose before using the sander.

5. Always hold the work firmly when sanding.

6. Always use the backstop when belt sander is in the horizontal position.

7. Always hold the work firmly on the table when sanding on the disc.

8. Never wear gloves or hold work with a rag when sanding.

9. Do not sand pieces of material that are too small to be safely supported.

10. Avoid awkward hand positions where a sudden slip could cause a hand to move into the sanding belt or disc.

11. When sanding a large work piece, provide additional support at table height.

12. Do not sand with the work piece unsupported. Support the work piece with the backstop or table. The only exception is curved work performed on the outer sanding drum.

13. Always turn the machine off and disconnect the cord from the power source before installing or removing accessories or when making repairs

14. Never leave the machine work area when the power is on or before the machine has come to a complete stop.

15. Shut off power and clean the sander and work area before leaving the area.

Bench Grinder

Main Article : Bench Grinder

Instructional Video: http://www.youtube.com/watch?v=znnurySP3no Safety Instructions:

1. Always wear eye protection (safety glasses or a face shield).

2. Remove tie, rings, watch and other jewelry and roll up sleeves.

3. Make sure the wheel guards are in place. Grinding creates heat; don't touch any portion of the workpiece until you are sure it has cooled.

4. Adjust the spark guards to be close to the wheel, and re-adjust these spark guards as the wheels wear down to a smaller diameter

5. Be sure blotters and wheel flanges are used to mount the grinding wheels onto the shaft of the grinder.

6. Stand to one side of the wheel when turning on power

7. Tool rests should be adjusted close to the wheels and thoroughly tightened in place so they cannot shift position while in use

8. Inspect the wheels before turning on the power. DO NOT use wheels that have been chipped or cracked.

9. When grinding, use the face of the wheel only.

10. Dress the wheel on the face only. Dressing the side of the wheel would cause it to become too thin for safe use.

11. DO NOT use a wheel that vibrates. Dress wheel, replace the wheel, or replace the bearings of the shaft if these are worn. Grinding creates heat; don't touch ground portion of workpiece until you are sure workpiece has cooled.

12. Shut off the power and do not leave guards as the wheels wear down to a until the wheel has come to a complete stop and the work area is clean when finished using machine.

1. No attempt should be made to operate the lathe until you understand the proper procedures for its use and have been checked out on it.

2. Dress appropriately. Remove all watches and jewelry. Safety glasses or goggles are a must.

3. Plan out your work thoroughly before starting.

4. Know were the location of the OFF switch is.

5. Be sure the work and holding device are firmly attached.

6. Turn the chuck by hand, with the lathe turned OFF, to be sure there is no danger of striking any part of the lathe.

7. Always remove the chuck key from the chuck immediately after use, and before operating the lathe. Make it a habit to never let go of the chuck key until it is out of the chuck and back in its holder.

8. Keep the machine clear of tools. Tools must not be placed on the ways of the lathe.

9. Stop the lathe before making any measurements, adjustments, or cleaning.

10. Support all work solidly. Do not permit small diameter work to project too far from the chuck, (over 3X’s the work’s diameter), without support.

12. If the work must be repositioned or removed from the lathe. Move the cutting tool clear of the work to prevent any accidental injuries.

13. You should always be aware of the direction of travel and speed of the carriage before you engage the automatic feed.

14. Chips are sharp. Do not attempt to remove them with your hand when they become “stringy” and build up on the tool post or workpiece. Stop the machine and remove them with pliers.

15. Stop the lathe immediately if any odd noise or vibration develops while you are operating it. If you can not locate the source of the trouble, get help from the instructor. Under no circumstance should the lathe be operated until the problem has been corrected.

16. Remove sharp edges and burrs from the work before removing it from the lathe.

17. Use care when cleaning the lathe. Chips sometimes get caught in recesses. Remove them with a brush or short stick. Never use a floor brush to clean the machine. Use only a brush, compressed air, or a rag
