Sometimes I'm good at that. Will I need to make one so there is a picture...even if the utility is only for a picture?Hey Paul, the title made me look.
I've watched a couple of videos on U Tube where an outside ring was held on the jaws so that the backlash was represented when tightening inward. This eliminates backlash floating and assures the jaws are biased in the clamping direction. For non-reversable 1-piece jaws, one could use appropriately sized beam clamps on each jaw since there are no reversing screws normally used with 2-piece jaws. Longer screws with sleeves in the outer holes of 2-piece jaws as well as beam clamps on 1-piece jaws will provide something for a ring to clamp onto when tightened inward. (edited)
Yes, thank you for reminding me. Basically, on 1-piece jaws there is nothing that would allow tightening the jaws on a ring to eliminate backlash. By installing beam clamps on each jaw, it becomes possible to clamp down on a ring on the outside with the inside of the beam clamps. It wouldn't require a great deal of clamp pressure for the grinding.Sometimes I'm good at that. Will I need to make one so there is a picture...even if the utility is only for a picture?
Uncle Harry, I think I saw a mrpete video like that at some point. I'll have to go back and watch it again. I have no idea about the second method.

I did find a video with the spacer method being used:
Still looking for the beam clamp method.
I understand the ring with the holes drilled in it. But my bolt pattern skills are pretty poor. If I had a rotary table for the mill
it wouldn't be a big deal...and dro. Just not to that yet.
