    Purchased 2 Mamiya RB67 lenses last week. Both are 127mm

    One lens was $13, and the other $14. They were ugly.

    Completely tore one down lens/shutter and rebuilt is last night. It is now CLA'd.

    I start the other one tonight.

    I love having the 127mm. Great lenses. They were rated ugly at KEH, because of their condition, but the glass was pristine. Got to love a great bargain !

    A friend gave me a pile of odds and ends. Found a Canon 102 speedlight (circa 1970?). Battery terminals horribly corroded. Used some Liquid Wrench (tm) and a screwdriver and scrapped the mess away. Result-- one perfectly working non-auto speedlight. I'll probably use it on my M3 when I need a small, simple flash unit.

    Mamiya & Compur Rapid

    Tore down and completely rebuilt a Mamiya 127mm lens and shutter. Works great.

    Repaired a Rolleicord II Compur Shutter Timing escapement gearset and flat spring. Now to reinstall and set...that's tomorrow.

    I can't wait to get this running again. It's been 6 months.

    I tore apart my 28/2 Kinon and relubed the helicals. In the process, I found out why they have the rep for oil on the blades (which mine doesn't)--the auto diaphram mechanism just inside the mount, running the lever that interfaces with the camera's stop-down mechanism and runs on a circle of ball bearings--was absolutely sloppy wet with oil, which was running all over the inside of the lens in places it didn't belong (and which I cleaned out). Now it works great!

    I attempted to fix my Hasselblad Distagon 40mm f/4 "C" lens focusing issue, but failed... Now I'm trying to fix my lack of posts so I can start a thread here with more details..

    A Balda Super Baldax.

    Cleaned up the shutter and sparingly lubricated anything which looked like it needed it. The shutter was taking about five seconds to close regardless of setting due to oil on the blades. It now seems to run perfectly.

    This is the first time I have attempted a clean out and re-lubrication of a shutter. My previous attempts at cleaning only have had limited success. It took me a long time to work out how to put back the ring which adjusts the shutter speeds and once it was all back together I was surprised at how easily and smoothly this ring turns. So much so that at first I thought I had not done it correctly and it wasn't engaging on anything. However, all speeds appear to be correct.

    The arrangement to lock the folding mechanism in place so it can't be folded up when focused anywhere but infinity needed some re-alignment and the viewfinder and rangefinder needed fifty years worth of dust cleaning from them.

    I also had a look at the overly complex auto spacing wind on mechanism. I was trying to see if I could simplify it and just use the red window to align the frame numbers but I ended up putting it back together as intended. These mechanisms are first turned the wrong way until they stop then turned the right way, also until they stop. The wrong way turn engages a drive pin at a different place for each frame to compensate for the gradual buildup of film on the spool and the correct rotation advances the film an amount pre-determined by the pin position. However it tends to stop too early so frames overlap. I have read that it is because the spool diameter is smaller now than it was fifty years ago and some people put tape on the spool to increas its size. I think I will just open the window and wind it on a bit to the next number.

    It is now ready to test.

    This camera came from an old chap who lived at the retirement home my wife used to work at. She brought it home for me to look at as it was not working. I lent him a 6x6 Zeiss folder to use whilst I had his camera but it turns out that he has now moved several hundred miles away to be closer to his family so we have ended up in possession of each others cameras. If the family ever get in touch, I will gladly give it back but until then, I will get some use out of it on his behalf.
