I think last time I made pie cuts on the inside and heated the metal and tapped it up.. Came out very nice.. Now I want to do it to my new quarters.. How did you do it and which way is best? I don't have a fender roller tool, cant rent one and I'm not going to buy one at that 250+ price. There is no paint on them right now, so it can't chip but I do not want to distort anything due to working so hard on gettin it perfect up untill this point. So the question again... How did you do yours? I know lots of people don't like to do this.. But I do.
