Fig. 116 illustrates the method of cramping up boards with rope and blocks. The wood blocks A, about 4 in. long and 1 1/2 in. square, are placed on the edges of the boards B, and a rope is passed round them twice and knotted. A small piece of wood is then placed between the two strands of rope and twisted round. This twisting draws the rope tighter on the blocks, there-by cramping the boards together. Three of these sets would be sufficient to cramp a number of long boards.
