I have a Barracuda II.
you can get it on Amazon or PSI. I bought extra chuck bodies so I wasn't wasting time changing jaws all the time.
I hold from the center of the pot, forcing out, to do the outside. then switch chucks and hold
from the outside, forcing in. Little secret for ya. Find an old motorcycle inner tube. cross cut it to your desired width, making a rubber band, and use it on the outside of your pot when holding on the outside. Prevents marks from your jaws. Works great.
