Patterson spiral

[Barney]

how many frames can you fit on one of those.

I inadvertently loaded 45 frames into a spool due to faulty counter on the film loader and I am wondering if it will fit on a spool or should I cut it and load onto two spools ?

I can't say for sure, but I can say that I've personally loaded a bulk-rolled film that had 41 full exposures, plus the leader and the waste frames at the end. I would say you'll probably be ok.

Even if it doesn't quite fit, the last couple of frames worth of film will be waste frames that were exposed to light when you attached it to the cassette in the bulk loader, so you could always cut that bit off in the darkroom / changing bag as long as it's not too long and not lose any pictures.

Even if you do leave any extra attached, it probably won't cause an issue because, even if it touches the film already on the spiral it will be the film base side, not the emulsion, so shouldn't affect development.

Thanks Nige,
Darkroom is back open !

If I were going to "cram" a nylon spiral, I'd be extra careful to make sure it was really dry.

It would be really annoying if the best picture on the film had a crease right across the frame!

IT didn't all go on, there was about 8 inch left I just wrapped it round best I could and stuck it in the tank, also it would not go in the drying cabinet so I had to cut it in half anyway. My fingers are crossed and I am hoping for the best. The canister was that crammed I could not get the fingers in of the leader removal tool, so expecting scratches from that as well.

I will be more careful with the loader now that I know that it cant count.
