Description

I made a couple of classic captured nut machinist puzzles on the lathe to practice single point threading and making multi-start threads. It was also lots of fun learning about thread milling as a method for cutting threads with a cnc machine. A good project to advance my skills with both manual machining and some cnc machining as well.
