    Questions regarding some details on the C1

    I have some detailed questions about the Calumet C1 (Magnesium) AKA the green monster:

    1. There is a piece of stainless steel sheet metal "washer" on the outside of the front rack (both sides) it has three holes in it. I thought it might be for reversing and permanently joining the front and rear rack, but the hole distances would not work for that..... What is this detail for?

    2. The steel retaining pin that goes into the front standard (secured by stop screws) that lock the rear rack when folded up..... are the pins threaded into the magnesium chassie?

    3. On top of and on both sides of the rear standard on the sides (vertically) there is a cast protrusion with a threaded hole in it. What is the purpose of this?

    4. Anyone has a full C1 service manual and parts list, exploded view drawing etc?


    Thanks!

    1) the tabs hold the rear extension up when folded.
    2) I think they are pressed in.
    3) that is where the GG frame screws into.
    4) http://www.cameraeccentric.com/, just hunt around for Calumet 1965.

    Paul,

    1. Ok, got it! One washer is broken one is bent a bit. But it fits. The folded position is a bit rickety right now since the stop screws for the steel pins are gone ( 1 MISSING 1 broken)

    2. Yeah, look like it... *could* be threaded maybe

    3. No, not the GG frame screws. These are vertical holes on the stationary standard, on the outside edge. I was thinking for some kind of wire frame to hold up the dark cloth maybe??

    4. Ok.

    Re: Questions regarding some details on the C1

    Ok, thanks everyone!

    Continuing the interrogation:

    1. Short of strip and repaint what's the best method of cleaning it up?
    The magnesium surfaces are a bit "corroded" - or just have this whitish covering of the bare grey metal. Not really pitted - corrosion is maybe too strong a word.

    Basically is seems to me friction surfaces needs polish and lubrication. Especially the focus rail. Advice?

    2. Same for painted surfaces, at this point it's probably best to give a gentle cleaning with a general purpose spray cleaner and soft cloth?

    3. The bellows have been black-gunk-painted in few places but is generally in good shape. Probably have some pinholes, haven't checked yet. Any advice?

    The ol' lady is good to go, but I want to give her the respect she well deserves!

    Re: Questions regarding some details on the C1

    Another newbie questions:

    The tab in the bellows to hold up the bellows - straighten the "sag" :

    Is it designed to hook onto the front standard, either directly or with a variable length chain?

    That seems to work best.

    With the tab hooked directly to the front standard you can extend the bellows at least to the maximum with the rail in the non-extended position. Quite a lot of force on the tab though.

    How do YOU use it?

    You are right about the holes on the top of the rear standard, they are for mounting a wire support for the darkcloth.
