Bob,
Does the taper part of the bushing fit the hole in the template plate or the O.D. of the bushing? What method do you use for hardening the punch? What is the side hole in the bushing for, or maybe was there in the scrap piece?
Thanks,
Paul

The piece was scrap and i kept it for myself. Just something from the junk box. The punch is from a kit that has ones from 1/16-1/2". Now mine has a 1/4" hole and i filed the writing off an old tap and use it as a punch since it has a nice point already...Bob
