    Using Paterson colour paper drum?

    Hi,

    I have an old Paterson colour print developing drum for 8x10". I have no other instructions than solution volumes printed on the side of the drum (90ml).

    The lid has kind of a cup where poured solution stands until the drum is placed on it's side, when the solution spills in the drum.

    The problem: There's small gaps on the lid's threads and developing solutions keep leaking thru them. But what is the purpose of those (see attachment image, it's upper right part). I can't figure the reason for them as the lid has already usual draining hole.


    Thanks,
    Jukka

    There probably should be a gray plastic gasket between the tank and the lid, just like their System 4 film tanks.

    I believe it does. I have one of these - I will check.

    I may still have the instructions and the temperature calculator somewhere.

    Hi,

    I got better pictures now. My drum has plastic gasket - perhaps it's not tight enough?

    But will the gasket sit tightly in any case as the top of the lid isn't even. There's a small cut out where the cutted thread's meet the lid's top.


    As I don't know the purpose of these cuttings, I assume that it's perfectly ok to just fill them?

    Put the gasket in the lid, I think you will see that it seals towards the inside of the lid, not where that small grove sits. Also that lid may work on a tank which has breaks in the threads, so it will drop down and lock in place within a 1/4 turn.
