Next beat down the depression in the plate. Draw a line with the pencil dividers where the depression starts; then hold the plate on the end of a block of wood and beat it down on the edge of the block with the ball-pein hammer along the pencil line, Fig. 63. If the plate is to have a deep depression, it will be necessary to anneal it, because it gets hard while being beaten down.
