[Woodworkers] Bowl Turning

[John McCaskill via Woodworkers]

Some people start with a faceplate to do all the rough turning and shape the outside of the bowl, others do that between centers. Either way works. The faceplate goes on the end which will wind up as the inside of the bowl. 

While doing the outside of the bowl, turn a tenon (OD mount) or mortise (ID mount) to fit your chuck. This is the outside bottom of the bowl. You should basically do almost all of the turning on the outside of the bowl at this point. 

Then reverse the bowl into the chuck. Keep using the tail center until you get all the OD work done, then remove it and turn the bowl ID. Finish sand and apply your finish to the bowl. Once you're happy with that, reverse the bowl to turn the tenon off or finish the mortise. 

At this point, you mount it on cole jaws (which fit on your nova chuck), or a jam chuck, or a vacuum chuck, or jammed between your chuck (with closed cell foam on it to keep from damaging the bowl inside) and the tail stock. Or, as Joseph said, a donut chuck or Longworth chuck. Lots of ways to get there. 

I use a flat point on my tailstock to avoid indenting the wood. Or, if you don't have a flat point, put a small scrap piece of wood between the tailstock and the bottom of the bowl. 

Turn the bottom of the bowl to suit. As I mentioned, turn it concave in the middle of the bottom so it only sits on a circle. Won't rock then, even if the wood moves a bit. Chisel off the last little bit of wood in the middle. Then sand & finish the bottom of the bowl. 

Voila!

Of course I talk to myself, sometimes I need expert advice.

A life? Cool! Where can I download one of those from?

Jam chuck donut Chuck's etc. I have a Longworth chuck which helps a lot. If you have a 4 jaw chuck you can use the Cole has that you can buy for a lot of 4 jaw chuck.
