I made this so called stamping die to make patches for the running boards on my 1950 and 1946 Chevy trucks (mostly the 46). Turned out fairly well, and the first piece I stamped is shown and fits the beads of the actual boards nicely. I only stamped a 4" long piece of 20 gauge just to see how it was going to do. I know the running boards are probably 18 gauge so I will try that next. I'm going to Alaska in two days so I probably won't get back to this project for two weeks.
