Years ago I acquired a Sorby Eccentric chuck with a 1"x8 tpi insert. I've since upgraded my lathe and now have a 1-1/4"x8 tpi spindle. I cannot for the life of me find a dealer who sells just the inserts for this chuck. I can find adaptors for the Sorby Patriot chucks, but I'm not sure they'll fit the Eccentric. As near as I can tell, the Eccentric chuck has a 1-1/2"x6 tpi thread in the body. Does anyone know what the male thread size of the Patriot insert is?
