TRY- This is used to test that one surface is square (at 90 degrees) to another and for marking out lines square to the face-side or face-edge. Woodworker’s try-squares have a carbon steel blade and a wooden stock, sometimes with a brass face, while engineer’s try-squares have a carbon steel blade and stock.

SCRIBER This is used to mark lines on metal and plastic. Hold the like a . When using a scriber make sure that the point is pressed into the angle between the try-square and the material. The point is made of Tool steel and has a 30 degree point angle. A is used for cutting curves and awkward shapes in or plastic. It has a very thin blade which is kept in tension by the spring metal frame. If the blade breaks a new one can be fitted by unscrewing the handle. The blade of a coping saw can be turned to different positions. This allows you to cut in any direction.

HINTS ON USING THE COPING SAW 1 Hold the handle with both hands. 2 The material should be held as low down in the vice as possible. 3 Saw at a slow pace with the blade held horizontal. 4 Always check that the teeth are pointing towards the handle.

TENON SAW A Tenon saw is used for cutting straight lines in wood. The stiff metal back on the saw keeps the blade flat and straight. You should grip it as if you were holding a gun.

HINTS ON USING THE TENON SAW 1 Hold the handle with your forefinger beside the handle. 2 When starting a cut, use a forward stroke, lightly. 3 Cut with sawtip, elbow and shoulder in a straight line. (Accuracy). 4 Whenever possible use the saw vertically. 5 Use most of the teeth, not a few in the centre of the blade. 6 Always hold work firmly.
