Due to all of the hole punching we were doing (my hands were aching Saturday night after all of the holes I punched) we designed and built a little fixture to bolt my hand held hole puncher into. This clamps to the grinding table or the jig tables and sure does make 18ga. an easy job...

It's just some scrap 1/4" angle and plate and a 4 x 4 drop. The verticle plate under the handle keeps the punch from rotating.

Welded up and primed with the Eastwood self-etching primer.

I sprayed the base with some of my "signature" Hammered Black from Rustoleum.

The handle is a left-over chunk of 1 1/4 tube (with a bend on it). I painted it red (for effect).

All set up and ready to go! This makes punching holes FUN!
