Of the dozens of methods of cramping picture frames the following has been recommended as being cheap and efficient. After shooting the joints, glue them, and place the frame on the bench. With a piece of cord bind the frame three times round the outside; then lift the cord from the edge of the moulding, and between the cord and the edge of the frame insert eight wood blocks, 3/4in. or lln. square and 3in. long; see Fig. 1. Now with thumb and finger press the mitres into position, so that the members intersect properly, and then draw the blocks towards the mitres, as in Fig. 2; this cramps the whole. When the frame is dry, remove the cramp, and carefully brad the mitres, boring the holes first with a bradawl, with the frame flat on the bench.
