Zorki 3M full CLA, part 4

A short series on fully servicing a Zorki 3M.
In this episode I have the shutter completed and I'm talking about the way I've had it set up as well as the methods I use to test and adjust these shutters. I'm also comparing the rangefinders from Zorki 4 and 3.

Applause for the digression! I always wondered why the gap widens as the curtain travels. Makes perfect sense to compensate the increase of velocity by a proportional widening of the gap. // I mounted a RF from a 4 in a 3 with only two of the four mounting points. (The spring in the original RF had badly worn out.) At first, I felt a bit ashamed about this hack. But as it happens, it proved to be perfectly stable for all practical purposes. // Glad you solved the brake problem. // I also check the Zorki shutters by visual inspection only: B, then 25, then the top speed for capping. I tension just as much as to pass these tests. I am aware that the shutter is then a bit slower than what the norm would require. But if you keep that in mind when taking pictures, the results will be just fine. There may also be a hint of uneven exposure. But you will be hard put to actually notice it.

I've always had a tendency to underexpose so for me personally a camera biased towards longer speeds comes in quite handy. On the other hand I know that the A in CLA means getting the speeds as close to correct as possible. But on the other other hand I think that when shooting such an old camera the experience and feel is very important so I'd gladly trade even a full stop of exposure for the smoothest experience possible (for a soviet camera).
