Modifying a 70mm Hasselblad back for 35mm

Has anyone here ever modified a 70mm back to shoot 35mm film? I have seen conversions kits advertised on ebay and now someone is selling instructions. Seems like a good idea as I will probably never use the 70mm back otherwise. Thanks for your help. Richard

I know I've put 35mm through a Holga which is a 120 film 6x6 camera - You end up shooting right over the sprockets which is an interesting look -

The 35mm canister just fits into the gap for the usual 120 roll, from there you just wrap it around a 120 spool at the other end and away you go ... (you also have to cover up the red window and guess how far to wind it each time but its not too hard)

(darkroom/bag required)

perhaps you could just give it a go - maybe respool the 35mm into the usual 70mm spools ?

I'm going to stick 46mm into 70mm cans. I just bought a 2nd Graflex back just for this. Some how I bet it'll be more involved with the Blad. IIRC it needs perforated film?
