Zorki 4 slow speed mechanism

[avidmaster]

Any tips on re-installing the slow speed mechanism on a 1957 Zorki 4? I think I’ve tried about 50 times now without getting it right. And I don’t have any hair left to pull out! 🤪

Thanks,

Mike

Last time I tried it, it has to be tensioned.

You could also try the guide I wrote some years ago:

Ko.Fe. is right, you need to tension the spring and hold the tension in the right place as you re-fit it.

Tension it by turning the ring cog and then put it back with the shutter cocked.
