This weekend's project was an Olympus 35RD with sticky shutter. There's a good on
kyphoto.com for this very repair, and just like Henry Taber, mine had a front lens cell which proved very difficult to remove. In fact, it seems that the factory applied some sort of adhesive to the threads. Fabricated a clamp wrench from a bit of birch ply, wrapped a rubber band around the unit for additional traction and
finally it yielded but even so it was much more difficult than it should have been. Made a couple of mistakes which required a a full teardown, and yup, the blasted lens cell was stuck again. Removed the adhesive as best I could and on the final reassembly, just tightened the assembly by hand.
This was my first time working with a leaf shutter, but I encountered no real difficulties there. Cleaned the blades with naptha then burnished them with pencil graphite for the heck of it.
Shutter and aperture rings felt very rough. Cleaned and lubed with a tiny bit of Molykote which helped greatly.
Light traps: Replaced with strips hand-cut from a larger sheet purchased at least 2 decades ago! But it's still pliable and non-sticky/crumbly after all these years.
Really kind of amazed at how they achieved functional auto exposure using nothing more than a single resistor, CdS photo-resistor and galvanometer! All else is accomplished via a perforated metal mask which varies the amount of light striking the photo resistor. That plus a sort of stepped guillotine blade whose ultimate height is determined by the position of the galvanometer needle. If I decided to, this would probably be the easiest camera to convert to 1.5V as that single fixed resistor couldn't be easier to reach.
In the end, the CLA took a lot more time than I expected, but now it's ready to use, auto-exposure and all.
