I didn’t spend too much time today on this. I spent alot of time trying to get the platform setup right. I started dimpling the trailing edge and it just didn’t look right. It was cupping and the dies were leaving marks on the skin. So I re-read the instructions for the C-frame and I decided to change hammers from my framing hammer to an 8oz ball pean hammer. I’m also swinging alot softer. It said that it would be a light hit. It takes two hits now to get the dimple done and they look right!

Dimples after the adjustment. MUCH better

My happy pose. This was very cathartic and I really enjoyed seeing how well the dimples looked
