Well, I started by making a couple of candidates to graft in where needed, but didn't like either one. So I switched to brute force. I have a modified tool I use in my air hammer. It can move metal with much more precision than a body hammer. I'd already used it to create the initial small dimples so it was just a matter of expanding and deepening the areas. You can see the results below. The deepest one on the left was moving pretty easily towards the last which indicated the metal was borderline overstretched. Or as engineers like to say, "The material was about to exceed its modulus of elasticity and suffer permanent deformation."
