rob_w Posted October 9, 2009 Share #1 Posted October 9, 2009 Advertisement (gone after registration) Hi, I was using my polarising filter recently and afterwards I found that the mounting ring had 'frozen' to the UV/IR filter on the front of my lens. No amount of force will separate the two, and I am scared that any further mechanical effort will just damage one or both components. Does anyone have experience with something like the photographic equivalent of WD-40 that will lubricate the threads so that the ring can be unscrewed from the filter? Many thanks Robert Link to post Share on other sites More sharing options...

dpattinson Posted October 9, 2009 Share #2 Posted October 9, 2009 Usually, this can be resolved by using some device to rotate the filters which doesn't deform the filter while operating. A camera repairer will probably have a couple of filter grabbers that will do the job Lens Filter Wrench Review The other approach is to jam the filter or the mounting ring against some non-slip plastic surface and rotate the other part. The plastic sheet prevents the other part from rotating, but doesn't pinch it in any way and may allow you to separate the two. Link to post Share on other sites More sharing options...

rob_x2004 Posted October 9, 2009 Share #4 Posted October 9, 2009 Your lens and filter will expand at different rates, and larger diameter. Put the lens in the sun for half an hour before using bills creeper. Oops. sorry Bill, lense for the sole of the shoei. Um ... Link to post Share on other sites More sharing options...
leicanut2 Posted October 9, 2009 Share #5 Posted October 9, 2009 I have a flat rubber ring that about 2 inches round by one inch thick it is made to remove filters I am trying to find the web site for it now. All you do is push the hard natural rubber against the filter and turn works better than a filter wrench I ever had. If anyone here knows what I have please post the web site incase I can't find it. Found it there neer the bottom of the page THEY REALLY WORK... Hint buy a large one thats bigger than you largest filter..They again work and are made from natural rubber. If two filters are stuck and come off the lens buy 2 rubber tools to seperate the two filters. http://www.micro-tools.com/Merchant2/e_lens.htm Jan Link to post Share on other sites More sharing options...
rob_w Posted October 11, 2009 Author Share #6 Posted October 11, 2009 Thanks guys, I will try these solutions and let you know. One question, should the foot be in the shoe when using it to free the filter? Hmmm! Cheers Robert Link to post Share on other sites More sharing options...
R.Julian-Huxley Posted October 11, 2009 Share #7 Posted October 11, 2009 Advertisement (gone after registration) large tie raps round each filter then turn in clock/anti/ wise directions with cloth or very tiny amount of wd/40 in thread groove warm up with hair drier works for me ! julian Link to post Share on other sites More sharing options...

underground Posted October 13, 2009 Share #10 Posted October 13, 2009 Here is a different approach. It works like a mini belt wrench. Use a pencil and a shoestring. The pencil gives you leverage and the shoestring tightens or loosens depending on the direction you set it up. (the spiderman pencil is the secret power tool for this method) Welcome, dear visitor!

rob_w Posted October 14, 2009 Author Share #11 Posted October 14, 2009 Love it. Thanks for the suggestion, I will certainly be trying it along with the shoe, the WD40 and a few choice English expressions this weekend! PS your photo exactly matches my dilemma, even down to the silver filter ring which detached itself from the lens rather than leave go of the step-up ring for the polarizer!

rob_w Posted October 17, 2009 Author Share #12 Posted October 17, 2009 Well, I tried most of these suggestions. And the winner is ... You guessed it, the shoe heel. WD40 and improvised slings failed to produce the desired result. So I cleaned the heel of a Rockport shoe. Firm rubber with just the right amount of give. Pressed down evenly on the offending filter, rotated carefully, and ... voila! ... movement. Now I have cleaned the escaped WD40 off the filter and all is fine. Thanks for the suggestions, guys. Next question: are there any preventative measures to stop it happening again? But I might make that a new thread. Cheers Robert Link to post Share on other sites More sharing options...
lars_bergquist Posted October 17, 2009 Share #13 Posted October 17, 2009 From a different but neighbouring thread: "1. A very thin film of Vaseline. Not more than a pinhead's worth, spread along the thread -- and spreading on the thread of the lens, too. 2. Soft pencil lead. 3. One of those soft rubber, saucer-like things that help old and feeble people to open screw can tops. None of the above points exclude each other."

Stephan_Chandler Posted October 18, 2009 Share #14 Posted October 18, 2009 I might recommend prevention. When I screw on a filter, I never tighten it beyond a fraction of an inch-ounce of torque. There's very little risk of it's unscrewing-off completely and falling to the floor: after all, the filter would have to go through several revolutions to unscrew completely. I do however, briefly and lightly unscrew and re-screw a filter from time to time to be sure it is securely on. Link to post Share on other sites More sharing options...
