Great idea! I was just making some 510+ posts and wanted to shim them up a bit. GMTA. Only, I didn't have a sheet of teflon. And I didn't have a 1/8" hole punch. So I drilled a bunch of 1/8" holes in some plastic and then chased them down with the 1/4" hole punch. My material kept jumping into a parallel universe and disappearing. So, I put blue tape on that catcher part of the punch, and it would grab my washers as I popped them.
