So, I want to CLA a problematic shutter on a lens bought on Ebay. Rear cell off, fine. Retaining ring and lens board off, fine. Now the only thing left is the front cell and the Copal #1. Yeah, yeah, I am a Wimp. I plan to find some latex gloves to help me grip the cell and the shutter. If it refuses to budge, the next thing I will try is putting the cell/shutter (inside ziplock bag) in the freezer to chill a bit, then trying again. If that doesn't work, what other options are there?.
I put some thick rubber bands around the front cell to get some more grip and cushion for hands.

Beyond rubber gloves and rubber bands, once in a great while I've found a strap wrench helpful.
Some caution is advised here.
Back when I was repairing shutters, I encountered a couple that had the front cells glue into the threads.
Apparently this was done to prevent the cell from loosening and changing position unknown to the shooter.
I guess it was a common recommendation at some point in history.

If you believe you can, or you believe you can't... you're right.
If you can't get it, Nancy, then bring it to the next MoNep meeting. Maybe me or one of the guys can get it loose for you. I have freed some that were seized before. Never ran into any glued together. Leigh can keep those!
Check for bottle and jar lid removers in the kitchenware section of department stores. Some have rubber padding that gives a good grip and the remover provides leverage.
Problem solved. Freezer plus surgical gloves did the trick.

Must admit I was a little sceptic about this, but just pulled a lens from the freezer and it came right out... Now to bang in another, somehow all my front elements seem to be stuck... Thanks for the suggestion.
Try turning in the correct direction.
You're welcome :-)
