Thank you once again, Mike ! Watching this silent movie gave me all the confidence I needed to do the trick on my Synchro Compur for Xenar/Technika 6x9. Beautiful, I feel like a king... Thanks (in a big part) to you !
Hi Hou Sometimes i use Isoprophylacohol 99%, and sometimes "Lighter Fluid" (Zippo or other brand's). In this case i use Isoprophylacohol 99%, because i did not have more Lighter fluid. Lighter Fluid is also very good the clean the focus helicoid in lenses. This shutter wasn't that bad in the slow gear, so Isoprophylacohol was good enough. To lubricate the slow gear, use "Sewing machine oil" the thinnest you can get, so go to the shop where they sell sewing machine's. Cheers
I use zippo light fluid and acetone to clean the shutter parts. It works for simpler ones such as prontor or copal types. I have not tried in compur ones. But I always find there is trace amount of residue left from the fluid on surface of the metals. Does this matter? I mean would this affect the lubrication of parts? Also, I use clock oil in lubrication, but someone from internet forums says,'No oil in shutter' or 'compur shutter works without lubricant oil'. I do not have any experience with compur shutters, but in your video, trace amount of lubricant can actually improve the performance of shutter? Am I right to say that? Nice work from you. And do we need to re-adjust the speed after re-assemble?
Hi Hou It's good to use Zippo or Isoprophylacohol 99% to clean the shutter parts and escapement and other gear wheel's.., but you should take care when using Acetone because if there is ANY plastic part it can worn it or melt it ( you can actually "melt" plastic part together with acetone..!!! ) so in my opinion and experiens, do not use acetone for cleaning parts . The shutter part with the blades and the aperture blades should be FREE from oil.., well some older lenses do need some oil on the aperture blades only. It's correct that some shutter's do not need any oil in the shutter because some of them have brass bearing or other "Soft metal" bearing's. SO in the other hand, use as little oil as possible. Yes, small trace amount, as i would say it just need a thin film of oil, that's enough, the thinner the better. YES, you need to re-adjust the slow speed escapement after re-assemble, and use 1 second setting to make your adjustment, it's A LOT easy'er. When adjusting, remember to put on the thin disc with all the grooves and the lock ring, cock the shutter, fire it, and listen when at the same time you look at your clock (1 second hand of a clock ). cheers :-)
I have fixed my slow 150 Symmar, thank you for your video. So easy to follow.

Nicely Done!
Hey, might I know what is the liquid you used to wash the escapement? Light fluid? Ethanol or acetone? Thx
