Nipple.
Figs. 21 to 24.—Scalloping Irons.
A lead piece (Fig. 27) for punching on should be from 6 in. to 8 in. square, and about 1½ in. thick. Lead is used because, being soft, it does not damage the points of the punches; but if lead is not handy, a block of wood 5 in. or 6 in. thick will do, if set up on end so that the punch does not cut across the grain.
