Well I was going to spend a few hours doing a bit of turning and it turned out to be most of the day. I put a pc of Buckeye up on the lathe and made a tennon for my supernova power grip jaws. Then reversed it and noticed that I made it a bit to small - very slightly to small. So I thought what the heck let me try something.....I ripped several strips of duct tape and wrapped it around the tennon and thought it may hold without slipping. It did hold very well and gave me the extra thickness to hold the vessel. I got lucky because I really did not think it would hold up.
However, I noticed that when I tightened up the jaws they seemed to have a slight /\ v shape in the jaws so I opened them up and made sure the set screws were tight and they were. There is a bit of play in them when nothing is in them but - meaning if you grab one jaw with your fingers you can wiggle each jaw just a tad.................On the other side of things they seem to hold fine and no slipping........So im not sure if this is a issue or just the way they are.............Thoughts ???????
Hollowed with my Monster rig and the new laser Randy sent....nice to have that bright light back...old one was dimming on me......
