Bolts to your workbench. Use guides to set perfect alignment for the blank, and strike the stamp with a solid blow with a 2-lb. hammer or maul. For bold images, consider stamping hot. The thumb screw lightly holds your stamp up in the jig and allows quick access for your hot blank. Slide the hot blank into its pre-aligned position and strike the stamp. It's not necessary to loosen the thumb screw holding the stamp in place before striking.
