Your comments about mechanical advantage make sense, I'm holding this bowl
on a 2" stub tenon and I'm making cut on a 10" diameter part of the bowl.
Therein probably lies the problem. Thanks.

That's a pretty small tenon for a 10" bowl. Either Mike Mahoney or Stuart Batty (I don't
recall which), at the AAW Symposium in Pasadena (2004) (where they recorded the Two Ways
to Make a Bowl video), says that the tenon should be about 40% of the bowl diameter. That
would be 4" on a 10" bowl.
