Jeff S Posted June 22, 2017 Author Share #21 Posted June 22, 2017 Advertisement (gone after registration) Before there was Loctite there was nail polish. Less hold than Loctitie but you're not putting any torque on the threads in normal use. And it's easily applied with the provided brush and available in hundreds of colours for the fashion minded. I prefer clear myself. Just a tiny dab on two sides of the thread is more than enough. Gordon Any concern applying so close to the VF? Any secret to removal, if desired? If removal requires a small wrench tool anyway, then maybe the tool can suffice without polish. Thanks. Jeff Link to post Share on other sites More sharing options...

mdemeyer Posted June 23, 2017 Share #22 Posted June 23, 2017 Nail polish generally uses Acetone (or something similar) as a solvent which can be bad for paint and some plastics. Not for me... Link to post Share on other sites More sharing options...
pgk Posted June 23, 2017 Share #23 Posted June 23, 2017 Loctite or equivalent thread locking compounds are available in different grades and on fine threads only a very, very small droplet would be required. This is what I would use. Over-tightening a thread simply makes it difficult to undo whereas loctite enables it to both hold in place and undo. I use it a lot.

CJJon Posted June 23, 2017 Share #24 Posted June 23, 2017 If one does go with threadlocker, make sure to get the removable Loctite type 242. It's blue. Never use the red stuff as it takes heat and tools to remove. Link to post Share on other sites More sharing options...
Jeff S Posted June 23, 2017 Author Share #25 Posted June 23, 2017 Thanks to all for the suggestions. With the many people who use diopters and magnifiers, I wonder if I'm the only one careless enough to lose one. I expected more to chime in on what they actually do for protection, if anything. One thing is for sure, I'll be very conscious of any loosening going forward. Jeff Link to post Share on other sites More sharing options...

Never use the red stuff as it takes heat and tools to remove. That's the one! For delicate, fine threaded parts which its essential not to overdo the application I usually use a toothpick to transfer a very small amount onto exactly where its needed. Works well for me. I transfer several small drops onto whichever thread is the one which allows any flow outwards rather than inwards, so for a male thread being inserted into a female thread on the camera say, I'd put small drops on the male thread.

Alas, I never could get those to stay screwed on. I'd lose one every few months - and so always kept a few spare in my bag. I like blue Loctite just fine... on my motorbikes. But then I've also got a really nice, digital Snap-On torque wrench I also use there. For tiny, delicate fasteners that have their torque listed in ounces (or grams), I wouldn't dare. There are obviously a lot of guys who have good results with doing it - good on ya. But I'd give it a pass. Link to post Share on other sites More sharing options...
friedeye Posted June 23, 2017 Share #28 Posted June 23, 2017 Lost 2 1.25 magnifiers that way. Took a break, and discovered I really don't need them. Maybe in another 10 years.... Link to post Share on other sites More sharing options...
Jeff S Posted June 23, 2017 Author Share #29 Posted June 23, 2017 I shot with Ms for over 30 years before using a +.5 diopter, which makes enough difference to figure out how not to lose it again. Never liked magnifiers.... have a 1.25 sitting in a drawer. Jeff Link to post Share on other sites More sharing options...

Jeff S Posted June 23, 2017 Author Share #31 Posted June 23, 2017 No bag at the time. It just worked its way loose... my own negligence for not tightening sufficiently. Jeff Link to post Share on other sites More sharing options...
FlashGordonPhotography Posted June 24, 2017 Share #32 Posted June 24, 2017 Nail polish generally uses Acetone (or something similar) as a solvent which can be bad for paint and some plastics. Not for me... Acetone is used to clean up nail polish, however we also use acetone to soften the holding glue for a rangefinder adjustment, which I have don on my old M9. No damage if a cotton tip is used to apply and clean up. Gordon Link to post Share on other sites More sharing options...
Guest Posted June 24, 2017 Share #33 Posted June 24, 2017 I noticed today that focusing my M10, which had been a delightful experience, was somehow a bit off; focus just wasn't locking in crisply (bad). Instead of a recent camera or eyesight problem, I discovered that my .5 diopter lens had somehow fallen off, likely at the end of my last shoot (good, considering the alternatives). Now, due to my own lack of attention, I'm having to spend another $175 (bad). Should I also invest in some Loctite, or something else, or just pay more attention to the tightness? Jeff Loctite is ok but I would use PTFE tape,or should I say a narrow strip of the tape.Loctite can be a bit permanent but PTFE tape is easily removed and will not leave any residue when you want to remove your diopter. This tape was originally sold for sealing thread connections on pipe installations. Link to post Share on other sites More sharing options...

Neither seems very elegant, but maybe I'm missing your suggestion. Jeff Link to post Share on other sites More sharing options...
microview Posted June 24, 2017 Share #36 Posted June 24, 2017 Around the thread if very narrow PTFE, experiment wit the shortest possible length. Won't do anything once the dioptre is in place, will just fall off the outer, I would think. Actually mine (new M10 type, not the adapter ring) isn't coming loose at all once screwed in by hand.

Wrap it round the male thread and the screw on the diopter. If that amount does not tighten the tread enough redo with a little more tape. Link to post Share on other sites More sharing options...
Guest Posted June 24, 2017 Share #38 Posted June 24, 2017 Threads are too fine and shallow. The teflon is too thick for that. I have PTFE tape which is very thin , pos only o.002 ins or certainly in that order. Link to post Share on other sites More sharing options...
jdlaing Posted June 24, 2017 Share #39 Posted June 24, 2017 I have PTFE tape which is very thin , pos only o.002 ins or certainly in that order. Still you have to make more than one wrap or al least overlap it to keep the threads from walking it right off. Pipe threads have a lot more tolerance than machine threads and Leica has very little tolerance. Link to post Share on other sites More sharing options...
