I've never seen any one do it, but I'm gonna give it a shot. I've done a little jewelry casting. So I've decided to try and cast some custom end pieces for a copper mod I'm working on. I don't have the machinery to turn metal, so I really have no other way. Figured I cast them and then use set screws to hold the caps on. Using silver for this. Would have been a lot easier to just buy that GG I like, but then I guess I couldn't say I did it. Besides $200 for the GG wowsa, that thing ought to be all silver for the price. Doing the burnout as I write so gotta go.
