Hi Chris! I've had similar experiences with naptha, it does clean old dirt and dried-up lubricants nicely, but often the mechanism remains 'too dry' and more or less 'stuck' after the naptha evaporates. Perhaps someone will enlighten both of us about proper lubrication for this type of shutter mechanism (oil or grease? do we put it only on the pivots or...?). I'ld just like to tell you that I got my shutter (in a 1918 Haeg 19x12cm folding plate camera) working again by immersing in petroleum (=kerosene, or paraffin oil, the liquid used as fuel in some lamps and heaters). It takes a longer time to evaporate than naptha, but leaves an oily film (I wiped off everything I could reach with a q-tip, especially the shutter blade surfaces). Probably not the best solution, also very smelly ... so, please, I'ld also like to read the proper way to lubricate shutters if anyone can tell us. For the helicoid ... helicoid grease...but what is it? Squashed bananas? Orca lard? I've read some warnings about fumes evaporating from the helicoid lubricant condensing on the lens glass, so if someone can tell us what the grease is (not only a brand name, which of course helps the people who can buy it where they live, but leaves some of us feeling frustrated ...). Thanks, Vlatko |
