Anyone try using the Graflex RH-50 6x7 back with 120/220 roll film? I'm experimenting with it on my Shen Hao. I tried manually rolling 120 onto the supply spool with the paper backing. That didn't seem to feed well, so I removed the paper backing.
I got the film to index properly without the paper backing, but I think there must still be a better way. Perhaps with a homebrew adapter for the 120 spools? I'd love to hear some tips from someone who has tried it.
Does anybody know if the 70mm film cartidges that used to be sold for these came with paper backing?
By the way, there are about 2cm between frames on this back, so I'm going to widen the opening about 1.7cm. That will give me a 6x9 graflok rollfilm back for under $50!
