OK, so if one had a roll of 70mm film, how would one go about respooling it into 120 rolls? Assuming one had the plastic spools and some used paper backings.
You have to cut it down to use it as 120. I made a trimmer for that. Doesn't work worth a damn. 70mm is the right width for 116/616, though. It's not hard to wind up with the backing paper. The only reason I fool with it at all is because I got 100 feet free.
