A common form of joiner’s bench screw is shown in general view by Fig. 89; Fig. 90 is a view looking from the inside, supposing the top, leg, and bearer of the bench to be removed, and Fig. 91 is a sectional view. D is the side or cheek of the bench to which the wooden nut A is screwed. The box B, which accurately fits the runner shown inside it, is fixed to the top rail connecting the legs, and to the top and side of the bench. Care is taken to keep the runner at right angles to the vice cheeks. To fasten the vice outer cheek and screw together so that upon turning the latter the former will follow it, a groove E (Fig. 91) is cut. Then from the under edge of the cheek a mortise is made, and a hardwood key F is driven to fit fairly tight into the mortise, its end entering E. The screw cheek is usually about 1 ft. 9 in. long, 9 in. wide, and 2 in. to 3 in. thick. The runner is about 3 in. by 3 in. and 2 ft. long. The wooden screws and nuts can be bought ready made.
