Looking at the result of that I wonder if that's really the way to do it and if the quality of the dimples will be ok.
Hopefully Scott will weigh in here, but I have done this where the skins were thin and it was unavoidable. YMMV, though, so use some small pieces and verify for yourself. I am not shy about using the deburring tool for a final fit adjustment of the dimple.
