This is the fourth part of my Atlas Lathe build series. I'm using a 3-phase motor. In this one, I install a new VFD to drive that motor. I also install a tachometer on the spindle so I can see how fast it's actually turning. I show how I made the brackets, installed the sensors, fitted the magnets, and how everything works. I even get make something. Hope you enjoy.
