There are many varieties of iron bench stops on the market, but the ordinary "knock up" stop, which is a piece of hard wood about 2 in. to 2½ in. square, and 9 in. to 18 in. long, fitting tightly into a mortise in the top of the bench, is still largely used. This is the best form of stop for all ordinary purposes. It is cut wedge shape, as shown by Fig. 32. This stop is raised and lowered by knocking with a hammer at top or bottom. The plane is not injured if it comes into contact with the stop, which also has greater strength than temporary stops screwed to the face of the bench top.
