When only a fewsimple pieces are to bebent the cost of even asimple block would beprohibitive, but whenmany pieces are wanted all alike, elaborate blocks may be made. Fig. Ill shows a block for bending flat bars. It can be made for any radius or even for differently shaped curves, and the working edge (a) can be made with a T or L section; so that shapes also can be bent. The block consists of a heavy cast-iron plate of the desired shape with a means suitable for fastening it to a bench or leveling block. The end of the piece to be bent is held in the groove (a) by the clips (b), which are fastened to the plate by bolts or pins in some of the holes
