D&A Posted October 23, 2009 Share #1 Posted October 23, 2009 Advertisement (gone after registration) Hi All, Just thought I might get some helpful suggestions I've had filters stuck to lenses before..which I'm sure at one time or another we've all run into that situation. This time it's a bit different. One of my Leica UVIR filters is screwed into the Leica thin adapter ring that comes with the current Leica polarizer-M kit and I cannot unscrew them apart. The adapter ring is sort of like a step ring for those that haven't seen one. Both of course have the correct filter thread pitch, so thats not the issue. I've tried most everything to get them apart without success. I even put them in a zip lock bag in the refrig. hoping "Cold" would cause constriction and make it easier to seperate the two. I got a good grip on both, but they seem as through they are perminanatly bonded to one another. Absolutely no luck. Any ideas would be appreciated..short of taking a sledgehammer to the two of them Dave (D&A) Link to post Share on other sites More sharing options...

zeitz Posted October 23, 2009 Share #3 Posted October 23, 2009 Yes, the trick is not to force the thin rings into an elliptical shape. Gripping with your fingers does that. And the harder you hold it, the more elliptical it becomes. I often use Craftsman rubber strap pipe wrenches. The kit I bought has two sizes. The smaller size would be useful on the filter rings. Since the rubber grips so well, you don't need to use much force. Link to post Share on other sites More sharing options...
rob_w Posted October 23, 2009 Share #4 Posted October 23, 2009 Ha ha! Hi Dave, forgive my laughter but I had exactly the same problem a few weeks back and posted the thread to which Bill refers you. In that thread I describe how I found the soft rubber heel of a shoe to be the best solution -- but I sympathise with your frustration before you do manage to get them apart. It is a strange problem in this age of modern materials. Good luck! Cheers Robert Link to post Share on other sites More sharing options...
pklein Posted October 23, 2009 Share #5 Posted October 23, 2009 Another possibility: Use rubber gloves, such as used for dishwashing, or unmentionable medical procedures... They should be dry and free from any residue from the above, of course... Link to post Share on other sites More sharing options...
clamcam Posted October 23, 2009 Share #6 Posted October 23, 2009 Actually, you want to warm them rather than freezing them. Carroll Lam Link to post Share on other sites More sharing options...
D&A Posted October 24, 2009 Author Share #7 Posted October 24, 2009 Advertisement (gone after registration) First I'd like to thank everyone for all their suggestions and I don't mind the "ribbing"..I deserve it! I probably overtightened the filter on the Leica adapter ring (which is paper thin) in the first place. I tried a rubber heal of a show, but that just slipped. Tomorrow after the filter/ring warms up to room temp, I'll try it with a pair of rubber dishwahing gloves and give that a whirl. I don't have much hope but its worth a shot. Does anyone thing I whould warm the filter in a slightly warm over (since puttting it in the refrig may have made chances of unscrewing more difficult? Last thing I want to do is put marks on either product. Anyhow, I'll keep looking out for suggestion and let everyone know what iof anything was successful. Thanks!

thrice Posted October 24, 2009 Share #8 Posted October 24, 2009 Rubber bands work well for me, just stretch one over the filter and one over the adapter before you twist. Link to post Share on other sites More sharing options...
d_brown Posted October 24, 2009 Share #9 Posted October 24, 2009 I'll offer my suggestion based on getting several very stubborn rings free. Holding the two parts with fingers, strap wrenches, etc. just deforms the parts and increases the friction. Heating or cooling just expands or contracts both parts equally and won't help. Try laying the pair down flat on a flat surface onto the gummiest rubber you can find (like the stuff the women use to line kitchen drawers). Then place another thin sheet of the rubber on top. Now, take a very flat surface like a small block of wood and lay it on top of that. Press the wood straight down very hard and twist. The parts will unscrew just like they were not stuck at all. I use a very tiny amount of Never Seez on the threads of aluminum rings to prevent this problem, but prefer brass rings, as they do not seize as easily. Good luck, and I hope this helps.
