I've been having a crack at making some small custom parts on a lathe
It's a nice training piece, short threads running up to shoulders in internal, external and left-hand forms. If you're not already doing so, now would be an excellent time to start threading away from the chuck.
you thread left-to-right (away from the chuck) for left-handed threads
the tool keeps going on thread cutting operations because you have to auto-feed it, so it keeps going until you disengage the half-nut that binds it to the lead screw.
