Thanks Mike O. and Chuck H. I want to go the route of turning my own as that minilathe hasn't done much other than a couple of chamber plug gauges for metallic cartridge and an aluminum sleeve which combined with a dial indy has become a firing pin protrusion gauge. If I can make a plug gauge for .22 Hornet, I think I can see well enuf to handle something 5/8" in diameter. Anyone ever fabricated one of those opposed wedge rigs comparable to the mechanism in the cheaper sort of bicycle handlebar stems?
