The third and forth shots are of the grill with the chrome removed. I am going to try to repair this believe it or not.
The fifth photo is of a pattern that I made out of 1/8" steel. It has a radius of 22.5" and the notches that are on either side are to allow clamps to hold down a piece of 1/32" x 1-3/4"x 24" flat brass. The brass is annealed then folded over and hammered flat on the sides. This was my trial run and was giving me so much trouble prior to the annealing that I was ready to give up. After the annealing, it formed very quickly although I was too aggressive and made dents in the sides that are hard to smooth over. This was practice, but I think the process will work. O down and nine to go.
