Following up on the last thread about my problems with tearing tennons when turning alot of times. I have a SuperNova chuck with spigot jaws that i have and will expand out to 2 1/4" if i remember correctly. and down to 1.6" . Being that part of my problem could easily be the tennon is to small for turning the larger pc's 8" diameter to 16".
I contracted Teknatool and asked for their opinion on purchasing another set of jaws that could accomodate larger turnings. The technical person said that the best he could think of to get is supergrip jaws and it would handle anything. The powergrip jaws contract from 3-3.8"
Just wondering what other people think of these jaws or the idea of purchasing these jaws which from what i have been told will greatly help solve my tennon problem ?????????????
Thoughts ??? thanks Dan
