    220 or 120 size bulk

    Has bulk film ever been available for 120 or 220 size rolls?

    Or am I just dreaming?

    You can get 70mm bulk and trim 4mm off the edge.

    4mm? That wouldn't fit on 120 reel though would it? Or by 70mm you mean the film is 65mm in width (as in '70mm' is 65mm for camera film, and 70mm for projection films)

    I thought that 120 film was 62mm? Can you trim it enough and get rid of the perfs? Or is there non perf available?

    Okay, maybe it is 62mm. I always thought 120 was 66mm wide. Either way, trim off the edge.

    There is perforated and non-perforated. I think an edge trim would get the perfs or pretty close.

    You can get 70mm non-perf and trim 9mm off, the film is about 61mm, I will be trying this soon when I have finished building a track and cutter to perform the task. The backing paper is a bit wider, maybe that is the 62mm.

    As for 35mm --- I have had good success modifying a Nikkormat to use non-perf 35mm film by wrapping some rubber tape around the middle of the advance cylinder, so that instead of moving the film by its sprockets, it moves by friction (plus the rather weak action of the take-up spool).

    It just isn't worth it. I'll just have to chuck my 220 inserts and buy some 120.

    Maybe I could remove the plastic piece that tells the camera it's a 220 insert and then
    cut the 120 paper backing out. Tape on a trailer paper and call it good.

    WAIT!.......... Wait...........wait. Please explain how you trim 4mm or what ever off of the edge of roll of film. Obviously in complete darkness. But if I tried doing that with scissors it would look like the straight line a drunk tried to walk in a roadside sobriety test.

    micwag2 check out the above links

    You can build a slitter and it's almost professional.

    Still to much bother
