I'm trying to press a .4 inch diameter, .3mm thick copper disc through a slanted hole and bend it into a cup shape like pic related. I'm using a drill press with a common pin punch in it. The best I can do bends it a little, then punches straight through.
I know nothing about working metal. Any advice?
