This is a good time to set clearances for different thicknesses of
metal. You
can take that 3/8 die to .525 or so for 1/8 thick or to .550 for 1/4
thick
with
a 1/2 punch..

3/8 die should be .387 for .125 thick material

LOL I just noticed that. Grant will probably want to place a radii on the
punch and die if he wants to do drawing with them (as the numbers above
might want to suggest).

But seriously, I suppose it depends on how nice Grant wants the slug and
hole, but perhaps closer to 20% total clearence?
