Welcome back to the machine shop! This video I’ll be making a much needed metal lathe upgrade and machining an improved tool post nut for my Phase II quick change tool post. As usual I start the design process at the drafting table before moving over to the engine lathe. Seems simple enough of a project, but that doesn’t mean it isn’t ripe for a slew of machining fails. This was bound to happen when trying some new techniques for the first time. Like metric thread cutting, precision compound rest adjustment, taper turning, and some questionable setups on the vertical milling machine.
