[Frameworks] "New" lomo tank filling with 16mm film

[Super8 Reversal Lab]

What I do is that I use multiple tanks next to each other. Every tank has 1 chemistry. I start and lift the top of tank 1, place the spiral inside, close the top and start agitating. When the time is up, I lift the top, take out the spiral and so on and so on. I do not fill/empty each tank, but leave them full. That works much quicker, there is less chemistry waist, you can wash the film far better and some more benefits...

    Hallo everybody

    I've been happily using a 50ft Lomo tank for years, mine is the "old"
    model (UPB-1 - version 1). Now a friends of mine bought the "new"
    model (UPB-1A or version 2) and I'm teaching him how to use it.

    As some of you probably now, the "new" one has a lower body than the
    "old" one (70mm against 78mm, here's the difference explained:
    https://sites.google.com/site/olexserviceskinor/processing-of-a-cine-film-in-home-laboratory/spiral-processing-tanks/upb-1-upb-1a-spiral-tanks?authuser=0).

    In the past I processed only super8 also with a "new" model, and it
    worked fine, but now, processing 16mm, I realized that a problem
    arises: the "new" one leaves a very tiny room for liquid to pass, so
    it takes a very long time to fill the tank, a problem that I never
    experienced with my "old" one. Long filling time makes developement
    uneven.

    When processing 2 x 16mm the problem is even worse: the gap is really
    thin, liquid takes ages to enter, and is also impossible to move the
    spiral up and down (my way of agitation).

    I thought of filling the tank first with liquid, and then dropping the
    spiral in the dark in the liquid, but is quite an hassle.

    Did you have the same issue? And what's your trick?

    Best
    Livio
