Chisels BEVEL • Edged chisels are slightly undercut. • Easy to push into corners. • They are normally used for finishing dovetail joints. FIRMER • Have a blade with a rectangular crosssection. • They are stronger and can be used for tougher/heavier work. PARING • A longer, thinner chisel which can be pushed into long joints such as housing joints. • It is used for cleaning up the joint and to make it an accurate fit.

Chisel Safe Always clamp wood down Never hold wood in your hands Use as many clamps as needed to prevent wood from moving Work with the grain when ever possible Keep both hands behind the chisel Use a rubber mallet only on chisels with metal tabs Keep your tool sharp

Hand saws Crosscut Saw The crosscut saw has teeth that is specially designed to cut horizontally through wood. All western saws cut on the push stroke • Saw length: 21 to 27 inches • Teeth size: 8 to 12 per inch • The teeth of the crosscut saw cuts wood at a right angle toward the direction of the wood grain. Rip Cut Saw Used for cutting with the grain of the wood. The blades are pitched between 85 to 90 degrees. This type of saw is specially designed to make what is called a "rip cut. " • Saw length: 23 to 27 inches • Teeth size: 5 ½ to 7 per inch

Back Saws that have smaller teeth; Length are shorter the typical saws. Have a metal backing rib to stabilize the blade. • Saw length: 7 to 15 inches • Teeth size: Varies per inch Dovetail saw, tenon saw and the miter saw. Coping Saw • Used to cut curves blade very thin. Break under tension • Saw length: 21 to 27 inches • Teeth size: 8 to 12 per inch Specialty Saws Japanese saw – cut on the pull stroke Frame saws; (keyhole saw or compass saws); hack saw

SAWS SAFTEY Handsaws • Select the right kind of saw for the job. • Clear the work area before you start to saw. Make sure that the material will not slip or fall. • The saw may jump out of the cut if you push too hard. When you start the cut, guide the saw blade with your hand. Begin by pulling the saw toward you. Move your hand away after the cut is started. • When you lay a saw down, put it where no one can brush against the teeth. • After you have finished with a saw, put it back where it belongs. • Keep your eyes on the saw teeth and the work. When you are nearing the end of a cut, ease up on the pressure stroke. • When completing a cut with a saw, ease up at the end. Hacksaws Select the right kind of hacksaw blade for the stock you want to cut. Look at the frame and make sure that the blade is installed properly. Hacksaw blades are made of hard steel. They will shatter if under high tension.

WOOD BLOCK PLANE: This type is old but is still used, due to the fact that they are lighter than steel planes and more comfortably for longer periods. JACK PLANE: This is the steel equivalent of the wooden block plane. Common in shop classes and garage. SMALL BLOCK PLANE: Used for light work such as producing 'chamfers'. Used for end grain. SMOOTHING PLANE: A shorter version of the steel jack plane. It is used for general work such as smoothing short pieces of wood. It is lighter and smaller than the jack plane

Planes, Scrapers, and Burnishers Guidelines • Be certain your work is securely clamped when using planes, scrapers, and burnishers. • Inspect wood for exposed splinters before using the scrapers. • Plane irons are very sharp do not run fingers along edges. • Keep your knuckles away from sharp edges of the wood. • Use the appropriate plane for the work at hand. • Use Bench planes for stock removal, smoothing rough surfaces, and fine finishing. • Use Jack Planes or longer planes for longer length planning (i. e. doors) to produce a straight line. • Use block plane for end grain. • Always keep the blade sharp. • Lightly oil the working surfaces after use. • Rest the plane on its side when not in use. • Store the plane with its cutter retracted to avoid premature edge wear.

Hand drills and bits • All work must be carefully secured on the drill press so that personal injury and damage are avoided. Use a drill vise, C-clamp, or V-block whenever possible. • When drilling thin metal, back up the material with a block of wood and clamp it securely. • ALWAYS BE AWARE of where your fingers are in relation to the drill bit • Bits get hot do not touch them after drilling • DO NOT USE bits that are dull, bent or damaged • DO NOT ATTEMPT to drill material that does not have a flat surface, unless a suitable support is used • DO NOT USE locking button unless the drill is mounted in a drill press stand or otherwise held stationary. ALWAYS unplug the drill when attaching or changing bits or accessories http: //www. youtube. com/watch? v=Csxgi. L 3 LN 50&feature=player_detailpage hand drill Brace drill power drill cordless drill

Screwdrivers Select the right kind and size of screwdriver for the job. Make sure the blade is in good condition. Never grind or reshape the tip without permission from your teacher. Do not use a screwdriver in place of a chisel. Do not use a screwdriver for checking electrical circuits. If you are working around electrical equipment, use a screwdriver with a rubber or plastic (insulted) handle. Never use pliers on a screwdriver for added torque. Clamp small work to the bench or in a vise when driving screws. Never hold the work in your hand. Wrenches Select a wrench big enough for the job. Never put a piece of pipe over the end of the wrench to get more leverage. If a wrench is too small, use a larger one. When you use an adjustable wrench, pull toward the movable jaw. This will keep the pressure against the solid jaw. Before you use a wrench, make sure the jaws fit tightly around the flats of the nut or bolt. Never leave a wrench attached to machinery that is on operation. Files Select the right kind of file for the job. Never use a file without a handle. Make sure the handle is secure. Be careful of the tang. Keep the files clean. A clean file will resist slipping on the work. Files are made of hard metal, but they are also brittle. They might break if you use them in the wrong way. Do not bang them against anything or pry with them.
