Kiev Shutter issues

[TVphotog]

Okay, I have my Kiev 2. CLA'ed the sucker and did a bit of repainting. The first roll through, before the CLA, looked great. There was some frame spacing issues, but that was expected. The shutter though I believe to be the culprit of the spacing issues and not the advance fork as normal. The advance knob does two jobs in advancing and recocking the shutter. The first job/part of the turn is film advance only. The second job is recocking the shutter. This is where I run into problems. I can not for the life of me make the shutter 'mess up' with it out of the camera. Once I put the camera together the problem arises. About half way through the recocking of the shutter something stops either the shutter or the advance knob. If I back it up slightly it will continue on normal. The exposure following this looks fine, so it is not causing an issue with the actual operation of the shutter. On the frames that this happened it did cause the spacing issues. I am thinking that there is a screw that may be tightened to much or may be too long. Ruben and such, any hints or ideas as to the cause of this malfunction.

TIA
Ken

Hi Ken,
It is the technical issues that are still keeping me out of the Kiev project, meaning there are at the forum several more acknowledgeable folks than me.

Nevertheless I am curious about one thing. I understand you have disassembled the camera, separating the shutter from the front part. Now there is a thin pin on the side of take up spool, somewhere between the two big screws there attaching the top casting.

This pin is seen from the take up spool side as a very thin screw, but it raises up to the top casting upper floor. I have happened to notice that the pressure you submit it lifts the whole top casting a bit up, or leaves it too loose by not screwing it at all.

Therefore you may like to try it a bit upwards or a bit donwards, and observe its influence both in the curtains lifting as in anything else. Ussually the correct position will be having this pin straight and not oblique, and the screwing low end being somewhat at the same level as the surface from which you screw it up or down.

As always, don't get mad, don't screw the camera out of nerves, remembering that what is not clear today will be known tomorrow.

Cheers,
Ruben
