Now form the inside

With the outside of the bowl complete, remove it from the screw center, and remove the screw center from the chuck. To hollow the inside of the bowl, remount it as shown. When turning the inside, take care not to catch the tool. Chucks do not hold turning stock as securely as a standard faceplate where several screws secure the blank. A bad catch can dislodge the bowl from the chuck. Once the final inside shape and wall thickness of the bowl have been achieved, sand it and apply the finish. For a bowl gripped in a recess, simply remove it from the chuck.

I think that oneway in Canada made the ist of these. I never did much turning till I got the oneway chuck. There is only so much you can do between centers.

Very informative! Metalworking 4 jaw chucks work differently, but that is another ballgame.
