Imagine a box built out of ABS, large enough to hold a water bath which in turn is large enough to hold three tanks for 4x5 film hangers comfortably. The box would have a light tight lid and the upper rim of the box would have one small notch to allow the lid to sit securely with the cord for my Zone VI Compensating Timer's probe running through the notch. The floor of the box would also be light tight but would allow water flowing from the bath to drain out. I'm still thinking about how I will make the incoming water supply light tight. I'm working up rough sketched for this box and when there's a draft, I'll scan them.
I'm envisioning a procedure along the lines of this:
Something, perhaps 1:1:175 pyro or 1:200 R09...with an N time of 1 hour. Semi-stand/EMA (after initial agitation) consisting of taking the lid off the box and and gently lifting and replacing each hanger one by one, slowly, at 15 minute intervals. Beginning at the 45 minute agitation, a DBI inspection of each sheet at each lift/replace cycle. Sheets would be moved to the stop bath tank as each is finished. When all the sheets are in the stop, they can all be fixed together.
Does this seem like a basis for a sound process?
