Hi
I have a nice Leningrad which is fully working. When shooting dry there are no issues at all. But when I put a film in, I can never go through a whole roll. Even if i am very careful and basically rewind the spring after every couple of rolls, after the first 10 or so frames i start having problems. The film will not advance, or will advance just a little. Then if i "rest' the camera and try again, sometimes i can get to the end of the roll. I thought I could use Foma 24 exp rolls as a sort of workaround. With the shorter roll I still get stuck sometimes, and even though i do manage to finish the roll i find I have some blanks, some streaks, some partial double exposures due to insufficient advance of the film.
As i said when shooting dry the film advances well and the spring feel really strong.
any ideas? I really do not know what else i can do… probably nothing eh?

Don't know about the Leningrad, but the problem of mid-roll transport failures is almost always due to some synchronisation issue between the perforation sprocket drum and take-up spool, most frequently a loose or entirely disengaged take-up clutch (resulting in the sprocket pushing more film towards the spool than the failed spool transport can pick up).

Leningrad has unique transportation system, no spockets. thanks for your info but does not apply to leningrad, which is somewhat of a unique camera.

Does it make an attempt at constant spacing? If so, that mechanism is what I'd be looking into first - in medium format cameras, that is usually the first thing to go bad. Or it might be a torque problem - as the take-up spool fills, more torque is needed due to the increased diameter, and a spring loaded or motor driven camera will become stuck as soon as the required torque exceeds what the drive can deliver.
