That makes sense. OTOH, I bought my Stubby from Larry Osterman, who had
been using it to turn stone, and I have never detected any after-effects.
He sold the Stubby because it wasn't heavy enough for the pieces he was
spinning, and upgraded to a custom-build Nichols. It was awesome--even had
a crane built on.
