I have a metal hole punch similar to this one, if not identical and was using it to punch holes in jar lids to make a fermentation chamber for veggies. The circular metal pieces get stuck in there and there's no real way to get them out, it seems. The only thing I can think of would be to use a drill, but without a reasonably-sized clamp (which I don't have) I don't know how I can get those out safely. I also tried using a smaller punch with no effect. via /r/DIY http://ift.tt/2B4ARLB
