I just picked myself up a new 4 oz ball peen hammer for pinning. I've been using an 8 oz up until now but i think i will get a smother result with the 4. I heard someone say that you should keep the ball polished. Ive given it a good rub with some 400 grit w/d and its pretty shiny and smooth. Do any of you guys think it needs anything more than that to achieve good results?
Thanks
Grant
