I've made a few threads recently threading in reverse before it dawned on me... I've got a threaded spindle! I'm wondering how smart that really is on my lathe. Is it safer to use a 5C collet configuration to hold the work? No difference? Which might be prone to more problems? A 2 3/8-6tpi spindle or a 5C collet thread? Is it a non issue for threads smaller than say X diameter? What diameter would that be? Oh ...and always feeding in with compound set to 29.5001 degrees.
