I am in the process of getting a project together. I need a round ball in the .420-.425 diameter range for the project. Ptching thickness can adjust for whatever size I can find reasonably. I found a .424 2 cavity round ball mold on evilbay but the price is quite high. Since I'd be happy with a single cavity mold, is there a source for such oddities at a fairly frugal price? Just figured I'd use the brain trust here to save a little time and energy.
