Today i decided to have a play with a little bit of yew. The small bit of branch I had had a knot so settled on making a small natural edged bowl. Wonderful stuff to cut. All went well until I removed the rough blanks from the chuck to store for drying.

Normally I use a mortice for the chuck, being small I spindle turned the bottom and used a tenon ?

So what's the best way to remove the tenon???

Hi

Turn a spherical cap form in the chuck to match the profile of the inside of the bowl, pack up with tissue to get a snug fit, bring up the tail centre for support and turn away as much of the tenon as you can. Tidy up what remains with a sharp knife / skew.

And that's called a jam chuck (or friction chuck). You could also buy cole jaws that clamp typically with rubber nubbins on to the outside of the reverse facing bowl to turn off the tenon.

Or you can make an mdf circle that's wider than the diameter of your bowl and reverse the piece. Then bring tail stock up and "pin" it to this large mdf/ply/whatever you have wheel and as long as you take light passes you should be ok.
 
I usually cut the bulk away with a saw [I use my bandsaw but it's a bit precarious so don't tell anyone] you could use a pull saw. Then I sit it on the bench sander untill it's flat, an upturned belt sander would do if it's clamped securely.

You just need to arrange a friction drive with the tailstock for support whilst turning off the bulk of the spigot.
The method can be seen near the end of this post showing the cleaning up the base of a natural edge piece.
Finish off any small central nib left with a sanding disc.

But you may wish to consider leaving the spigot in place until the piece has dried and use it to hold the piece while you clean up the turning and thinning the cross section.

Hi Bob

Whilst the methods you describe are fine for reverse mounting bowls with turned rims neither will work very, if at all, well with natural edged bowls due to the irregular nature of their rims.

Leave it on until you have dried the blank and turned to final size then use the method that spindle has suggested. That is what I would do
