Update on Plus-X Aero.

I attempted to slit down a 4 roll long length of 70mm down to 120 instead of going one roll at a time. It works with non-perf. With perforated film I do not suggest doing this. It was jam-o-matic central.

Oh nooooes

Yeah, it’s hard enough to do it with non-perf. There are a few spots where the film got off-canter and caused rough spots. Can’t emagine doing it with perfs. I will be so happy if this lead on 61.5mm film pans out.

Developing a roll of the bad batch now. Might have been light stuck too. I had bad luck with that session.

I am making a cutting table with guides and levers around te cutter box to align the film properly. And yes, I have film with perfs that didn't like the half a millimeter of uncalculated varnish coating. A some point the film bent and one of the cutter didn't cut properly. But my guess is that if you hold the film in your hand the pulling is not even enough and can lead to desasters. I will test the mkII soon :smile:
