I saw this extremely courageous (is that the right word?) guy with this router/lathe combo, and I thought, “Why not make a machine that can do that while you are at a safe distance away?”
If you added a piece of stock on a spindle, with all the lathe parts that requires, you could use the MPCNC to move the rotating bit (which he claims is much lower drag than a cutter) to make a turned piece. Not sure if that would work for aluminum, but it seems like it’s worth a try for some wood. Anyone want to figure this out so I can follow your example in a few months?
Maybe you could just embed one of these under an MPCNC? http://www.harborfreight.com/5-speed-bench-top-wood-lathe-65345.html
