    Flip aperture lever 180 degrees on a Copal shutter

    Hello,

    Is there an easy way to flip (more precisely rotate) the aperture lever of a Copal shutter by 180 degrees, such that it goes to the "bottom" of the shutter, on the opposite side of the cocking lever?

    Thank you.

    Without knowing the exact shutter, I think the only way to find out is to take it apart and see.

    Thanks. It's just a generic Copal #0 shutter of the latest model.

    However, based on photos I've seen of disassembled Copals, it seems the aperture mechanism sits behind a host of other parts and would be a pain to extract. It seems to make much more sense to add a shoe to the little pin indicating aperture on the "bottom" part of the shutter.

    My goal is simply to flip the shutter upside down for ergonomic reasons--I like to cock with my left index finger and release with my left thumb cradling the lens.

    I put the shutter wherever I like it and that varies by camera and room.

    Some shutters have or had a locating pin/screw that many like me, remove and promptly lose. It's tiny!

    There are basically only 3 reasons why it canít be done:

    1 you already addressed with the screw.
    2 itís on a board with something like a Linhof cable release QR socket installed.
    3 itís in some recessed boards
    Otherwise they just need a Rodenstock/Linos lens wrench and loosen the Jam nut and rotate the shutter and retighten.

    You are correct, I forgot about the added complications.

    I do remember reading them now...

    To be very clear, I like the ergonomics of the cocking lever and the shutter release "upside down," but I like the ergonomics of the aperture lever right-side up.

    With the shutter "upside down," the aperture lever becomes hard to reach and move (one has to locate it by feel). That's why I was curious about the possibility of rotating the aperture lever internally (hence "the opposite side of the cocking lever" in my original message). This now seems clearly unnecessarily complicated.
