Only if you have a lathe with a fly cutter and are willing to do some fancy setup work. Kozo shows how to do this in his books with a faceplate, but it requires carefully counterbalancing the work so the headstock doesn't bounce around. I used the sandpaper-on-a-disk trick and it didn't take too terribly long. I made the carrier with a hole cutter (trepanning tool) and a piece of 2x4 pine, with a 1/4-20 bolt through the center hole. Sometimes, doing it the "right" way involves much more time and effort than just doing it the "cowboy" way. -vance-
