Barring tremendous catches, I think a 2" tenon would be perfectly adequate
for a 10" bowl.
I think I have gotten myself out of this mess. Last night, I used medium
viscosity CA glue and re-attached the tenon to the bowl. I finished
hollowing without mishap tonight. I have power sanded the exterior and
interior of the bowl. Now all that remains is to reverse the bowl and turn
the foot, which should be fairly straight forward. God bless the guy(s) who
invented CA glue.

I am uncertain if it translates over to your situation but some time back
I
recall reading that if you use a faceplate the largest diamter would be no
more than 3 X the isze of the faceplate, i.e., a 3" faceplate would allow
the turning of a 9" diameter bowl.
Also, as others have mentioned, a large factor in the determination of the
size of the tenon would be the nature of the wood itself. Hope all turns
out well.

I went to the shop to turn a bowl. I had a dry 10" X 10" X 4" Honduras
Mahogany blank that I bought some time ago. I turned the outside shape
with
a 4" foot and a 2" tenon. I power sanded the exterior and reversed the
bowl
to hollow it. After hollowing, I intended to reverse the bowl again and
turn away the tenon, leaving a simple 4" concave foot.
I trued the rim and started to establish the wall thickness, using my
new
Crown PM bowl gouge. All was going well. The bowl was hollowed about
halfway down when I got a king-sized catch and ripped the bowl from the
chuck, leaving the 3/8" X 2" tenon behind in the jaws.
The bowl is intact, except for a deep gouge in the rim, which can be
turned
away. I salvaged the tenon from the chuck jaws and carefully glued it
back
to the bottom of the bowl using medium-viscosity CA glue. I'm going to
leave it clamped overnight and try again.
Considering the ease with which I was able to rip the tenon from the
bowl
made me wonder, is a 2" tenon adequate for turning a 10" diameter bowl?
I
suspect that it may be on the small side. Thoughts?
