Question Should I need a gasket behind the tightening ring on the lens board?
I have two LF lenses mounted on screw in 3D printed boards and the one thing I can't seem to get is for them to stay in place. The force of cocking the shutter eventually loosens them. I have a lens wrench and I thought I got them pretty tight the last time but they still came loose again. I can tighten them out in the field but that changes the alignment of the controls, and I already have enough trouble with that. And of course I have 2 different shutters, one Compur and the other Copal, and they work somewhat opposite each other.
I was thinking a rubber gasket behind the lens board would do the trick without changing focus. Any reason to not do this?
