There are various appliances employed in cutting mitres, the simplest being known as the mitre block. The work is laid upon the rebate C (Fig. 55), and the saw kerfs A B serve as a guide for the tenon saw. The best form of mitre block is made from a piece of dry beech, about 16 in. long, 6 in. wide, and 3 in. thick. A rebate c is cut to about the size shown, care being taken that the angle is perfectly true. Lines A and B are set out to an angle of 45°, and they then are squared down the rebate and back of block. The lines are cut down with a tenon saw, and upon the accuracy of the sawing depends the value of the finished mitres. Fig. 56 is a section of the mitre block as commonly used by the joiner. This is merely two pieces of wood (deal, as a rule) planed up true and screwed or nailed together. This plan answers very well, as when it becomes worn and out of truth another can be made for a few pence. The block shown by Fig. 57 has a ledge on the bottom as shown; owing to the inward slant the work is more easily held.
