Of course, one must be careful not to unscrew the chuck on some lathes, like mine.
Has anyone devised an easy way to "lock" something (like a 4-jaw or a 5C collet chuck) to the spindle of an SB9 to prevent this? (other than over-tightening the chuck?)
I've threaded to a shoulder by running the tool upside-down and the lathe in reverse, and it works great otherwise. Oh, well the very first threads I cut were inadvertently left-hand thread, but that's another story.
Science. If you don't understand it, don't talk to me about how it's going to end the world.
