    I'm trying to find out which current JOBO tank wil allow me to us my old-style reels.

    Could someone with a 1520 tank (2x35mm) please measure the inside diameter and depth, and reply?

    TIA

    Just retrieved a 1520 tank from my darkroom:

    Inside diameter = ~ 3.80"
    Inside Depth = ~ 3.75"

    I have a couple of unidentified JOBO reels ... their outside diameter is ~ 4.75" and the Inside diameter of the "spindle hole" is ~ 1.0".
    I don't know exactly what JOBO tank they are supposed to fit ... I picked them up at a flea market. They cannot be used in either the 1500 or 2500 series tanks.

    Hope this is of some help.

    Brian and Ed,
    Thanks so much for taking the time to check that for me. That info is hugely helpful.

    My reels are about 4.5" which will wastefully fit a 2500 tank and now I see will not fit a 1500 without the help of a mallet. I have a tank that will take up to five of these old reels or two old style 4x5 reels and would love to find one that would take a couple of 35's or one old style 4x5. Looks like I am out of luck unless I find something in a junk bin.

    Flotsam,

    The current series of Jobo tanks/drums were designed to be compatible with rotary processing in Jobo machines, while the previous series were not. While both generations of the smaller types are cross compatible, the larger types are not; the previous large type is actually smaller in diameter than the current one. So the spiral you have (which I think should be made out of transparent material for both spiral flanges) was for the previous larger series.

    I acquired a few of these old large series spirals but without a tank to use them with, then another large format photographer friend bought a tank of this type with only one 4X5 rack; he was grinning ear to ear when I presented them with what I had. Best sort of a deal: I reclaimed some space, and he owes me one!
