318 and 10's
Ah, your a sheet metal worker......that explains it...
I'm truly just kidding SP. My mentor in the early 70's hammered tin as well. It was always a inside joke with us as I became a plumber for a years.
I really am interested in how you do things, although you are hesitant to divulge your secrets, which I understand. I'm sure there were some that wondered who I thought I was when I first came here. I'm willing to start with a fresh attitude and hope we can get along fine.
