    Film curtain crank on Mamiya 7

    The little fold-down tab for opening and closing the film curtain on the bottom of my M-7 split. I got a replacement from Mamiya, but no instructions on how to take the old one off. It appears to have a pin, similar to that which holds a watch-band on the watch, but the clearance is so tight that not even my tiniest jeweler's screwdriver will help.

    Anybody know the answer to this?

    Call the parts house you bought it from and ask them. I replaced a part on my M7 and they were most helpful.

    Hello

    just to let you know I make spare solid brass levers (crank) for M7 that last forever! I add a simple instruction document with photos for a step by step DIY job.
    if anybody would ever need one, just let me know!

    all the best

    I can only guess how that foldable crank is fixed. Most probably it is a plain steel pin (that has to be driven out to release the crank).

    At model-craft shops you shall find steel wires of apt thickness. Cut off a short piece, flatten the ends and use it as a driving pin.
    Maybe you'll find at your home a tiny nail or needle of apt thickness, then proceed as above.


    EDIT:
    I just had a more closer look at a photo of a Mamiya 7 II bottom plate; the crank seems fixed different from what I thought above.

    Can you take a digital picture of it? I've one like that.
