Tips for avoiding fat rolls with Ondu cameras?

[chdorner]

I've been having issues recently with my Ondu 6x12 Multiformat (second version). Every time I unload the roll it isn't tightly wound and getting light leaks at the top and bottom for the last few frames. For example, I recently shot a roll with the 6x9 frame size and three out of eight frames ended up with light leaks.

Does anybody have some tips on having the roll tightly wound?

I use it a lot for travelling, so I'd rather not have to bring a dark bag wherever I go.

Sounds like this might be cured by, e.g., a flexible steel foil applying friction on the rim of the supply spool.

Look at Holga modifications. I have a tab made from card stock and Duck tape that puts a little pressure on the take-up film. Holdas are a problem with fat rolls too and this works for me. I don't have a photo handy so show unfortunately.

Thank you Bernard and Bruce! I've checked what I have at home right now and taped a cable tie to the side of the take-up spool chamber and bent it towards it to put some pressure on the take up spool. It worked perfectly.

Here's a picture if somebody else runs into the same issue:

That is a great idea!

Yes, simple and effective!

I'd love to see some sample photos taken with this camera- have you got any to post?

Here's a 6x12 shot: https://www.instagram.com/p/BXGKIuahtbG/
and here's a 6x9 shot: https://www.instagram.com/p/BTKDPvcjMNs/

I have some more on my Instagram, note that the ones that have a really noticeable vignetting on one side (usually on the left) have been taken with a faulty pinhole. Ondu sent me a new pinhole which fixed the problem.

This thread came just at the right time - I've recieved my Ondu 6x12 Multiformat just today.
