Rh form of this is shown at Figs. 33 and 34. A block is screwed to the stop, and to this the nut of an ordinary shutter bolt is fixed. A slot is cut in the cheek of the bench, as shown. The shoulder of the bolt works against a large washer. This stop can readily be raised or lowered. Two or three steel nails driven in near the top of the stop and filed to form teeth can be used to hold the work. A very useful stop may be contrived, as shown by Fig. 35, by filing one end of a back flap hinge so as to form teeth, the other flap being screwed down to the bench. A long screw through the middle hole in the loose flap affords means of adjustment. By loosening this long screw, the front edge of the stop may be raised, but to retain it in its position it should be packed up with a piece of wood, and the screw tightened down again. A plain iron stop with a side spring to keep it at any desired height is shown by Fig. 36. This form of stop fits into holes mortised through the bench top. Figs. 37 and 38 show good forms of adjustable bench stops that are obtainable from tool-dealers; their principle is fairly obvious on reference to the illustrations.

Sawing Stools or Trestles.—The three-leg sawing stool is of but little service and almost useless for supporting work in course of sawing. Probably one of the best forms of this useful appliance is the four-legged stool shown by Fig. 39. This needs to be built substantially.

Cramps.—A hold-fast for temporarily securing work to the bench is shown by Fig. 40. The old-fashioned hand-screw cramp (Fig. 41) is made of wood entirely. It is a very useful tool in the joiner's shop, and is used for holding together pieces of wood when glued for thicknessing up. It is indispensable when glueing up face veneers for shop fittings, etc.; these screws are made in different sizes suitable for heavy and light work. Iron G-cramps are a very useful form, the smaller sizes being made with a thumbscrew (Fig. 42) and being used for light purposes. The stronger and larger kinds will take in work up to 12 in.; greater force being required, the screws are rotated by means of the usual lever. The many varieties of iron cramps include the Hammer instantaneous adjustment cramp and a sliding pattern G-cramp, both of which have advantages in many cases over the common G-cramp, a form of which, with thumbscrew, is illustrated by Fig. 42 (p. 10). Sash cramps and joiner's cramps (also shown on p. 10 — see Fig. 43) are in common use, a number of patent cramps with special advantages also being known. Figs. 44 and 45 show a useful cramp for thin work. The wedge cramp (Fig. 46), known as a cleat, is also very useful for holding boards together after they have been jointed and glued. The cleats are kept on till the glue in the joint is dry. The wedges prevent the board from casting. Iron dogs (Figs. 47 and 48) are
