A “donkey’s-ear” is used for mitreing or bevelling the edges of wide but thin material, with the cut at right angles to that adopted for stouter mouldings. Fig. 70 gives an idea of its form and construction. Fig. 71 shows another handy form of mitre-shoot for wide surfaces that have to be edge-mitred. This also is known as a “donkey’s-ear,” and it consists of a rest A for the material to be mitred, a bed B for the shooting plane, a guide C for the plane, and a frame D for the purpose of elevating the appliance to a convenient height by fixing it in the bench-screw or to the tail of the bench. The rest A is made of a piece of deal 1 ft. 3 in. long, 4 1/2 in. deep, and 3 in. thick, and has a rebate run along two of its edges (see the section), Fig. 72. The bed B should preferably be of teak, as this wood is of a greasy nature and does not cast. It should be about 2 ft. long, 3 in. wide, and 2 in. thick. The guides C are 1 in. thick, and project about 1/2 in. above the bed. The frame D is made up of 3-in. by 1-in. deal, and tenoned through the bed with barefaced tenons, with shoulders towards the rest.
