I'm afraid I'm not familiar with the lens & camera you're working on, but I regularly play with 100-year-old lenses that have never been disassembled, so I have a couple of suggestions:

The Flexi-Clamps from Micro-Tools are good tools. Get some rubber hose from an auto parts store, slit it lengthwise and put it over the handles to protect your hands. You can crimp some hose clamps to fit the Flexi-Clamps; run them up the handle, so you don't have to try to squeeze and turn at the same time.

Micro-Tools sometimes lists a nice small strap wrench that can solve some problems. Take care not to put so much pressure on it that you dent the part, though.

When all else fails, take a block of wood and ream out a hole to fit the part very tightly. You can put a piece of tape around the part to protect the surface and take up any slack. Cut the block in half and put it around the part. Clamp it there with a double-screwed wood clamp, then put the wood clamp into a bench vise. Now, you've got the part immobilized, and have two free hands to turn the opposing part.

Good luck.
