Here's a short video of my first mill/turn part. Worked out surprisingly well. Annealed 4140 running 1500 RPM @15ipm. These used to take me over an hour to cut on the mill using a collet spin index fixture and cutting SEVERAL flats then blending them on the lathe. Code was generated with Fusion 360. I had to modify the post to allow it to spit out turning code for Milltronics post.
