===================== Sounds like a good idea. Cutter will automatically be centered and both sides will be symmetrical. Does the tool have enough strength for anything beyond sheet brass? What is the working radius of the tool? Do you just have a flat on the tool to orient in the holder or is there some special technique?
Do you use soft drill rod / silver steel and harden or grind round hard tool steel? We are limited to a propane torch and a bucket of water for hardening (but if the old timers could do it ? )
