    The Plate-elevator is an instrument used for removing metal plates from the lead counter during the operation of swaging. It can be readily made out of a suitable piece of steel wire, or by softening and filing up an old six-inch rat- tail file. The end can be given the required curves (see]Fig. 15), by Fig. 14. bending it when red hot over a thick round rod of iron or steel. The point of the instrument is flattened somewhat on its upper aspect, and at the extreme point a slight notch is made to prevent it from slipping away from the plate, when the latter is being prized or lifted out. It should be hardened and then tempered to a blue colour. A handle can afterwards be fixed to the part that corresponds to the tang of the file. Fig. 15. A double-ended brass modeller, (see Fig. 16) is a most useful little tool. It is principally used for moulding up pattern lead, to make the pattern for the plate. It should be about half an inch longer than the illustration.
