acetone or nail polish remover... same stuff, different price.
lacquer thinner works the same if you have some around.
it was common for manufacters to use lacquer as a lock tite.

No experiments today - out of town.
Crazy glue, will often fracture if frozen. That didn't work when you tried it?

Well, end of this project :(
There was no way the front lens could come out the back of the cell, so that inner ring had to be a retaining ring. I threw everything I had at it. Heat, cold, solvents, vibration, and finally brute force. I eventually use a jewler's saw to cut slots in the ring for a lens spanner to fit into. Applying an entirely unreasonable amount of force, I got the ring to unscrew about 30 degrees before the lens spanner snapped in half and the shattered stub smashed straight into the center of the lens. So that Tessar is no more.
The price of a education can be dear.

Nail polish no longer has acetone on it. I once got my four fingers glued with Loctite while holding a bridge on a guitar that I was gluing. I used nail polish with no avail. Then my neighbors had acetone, acetone did it.Quote:

I'm glad I didn't have this happen to a more expensive lens though.Quote:
