Hack saw, coping saw.
A U shaped frame holding a very narrow, thin blade for cutting intricate shapes.
A 'coping saw' is a type of small frame saw with a U shaped steel frame holding a very thin blade. This blade can be rotated in the holder so the saw is capable of making very intricate cuts. -It is very similar to a fret saw.
A tenon saw has a rigid, solid rectangular blade about 12inches long and 3-4 inches wide, and around a 1/32 inch thick and has a reinforcing strip of metal along the top edge of the blade to keep it straight and rigid. It is used for cutting wood joints accurately, and can only cut in straight lines. A copingsaw, however has a much thinner narrow blade stretched in a frame shaped like a 'D' with the upright of the 'D' being the blade. The handle is in line with the blade. Coping saws are used for cutting round and complicated shapes out of wood (or, with a suitable blade, metal). The thin blade means that the saw is able to cut out complex shapes accurately as the saw blade can reach small corners and follow quite complex shapes. A fret saw is very similar to a coping saw except that the 'D' shaped frame is very elongated and the blade very fine and thin. This saw is used for cutting intricate decorative shapes out of thin wood. A scroll saw is a motorised fret or coping saw where the blade moves up and down through a metal table. Instead of moving the blade through the wood or metal, the wood or metal is moved round the moving blade, producing the intricate cut.
A Hacksaw has a thin, flexible blade - held under tension by a screw mechanism. A tenon saw has a broad, rigid blade.
There are four basic parts to a bow saw. They are: frame, blade, handle, and adjustment.
The frame, handle, blade and adjuster screw.
To perform a bow saw blade replacement, first loosen the tension on the saw blade by turning the tensioning knob or screw. Remove the old blade by sliding it out of the saw frame. Insert the new blade into the frame, making sure the teeth are facing forward. Tighten the tension on the blade by turning the tensioning knob or screw until the blade is securely in place. Test the tension by plucking the blade like a guitar string it should produce a clear, high-pitched sound.
I use a carbide tipped saw blade (100 tooth) to cut alot of aluminum, but you have irregular shaped and thin aluminum that can tear out very easily. Remember, the finer the tooth, the less tear-out, try a test piece first.
It is shaped like that because it is used for thin plywood. The coping saw also has a ''clamp'' to help cut plywood.
It is a hacksaw, which is a narrow fine-toothed blade set in a frame.
handle, blade and iron frameANS 2 - There are some really nice ones now. My current favorite is a German one that has a tubular steel frame, really light weight and keeps the blade very tight due to it's shape. -See the current Lee Valley catalogue.
the handle is usually made out of wood , the blade and frame are both made out of metal.
