Large developing trays for roll paper 47" wide

[simonbrismo]

I'm searching for large developing trays that can swallow paper with the width of 47". Happy to get to know where I can buy em?

Talk to Bob Carnie.

No one manufactures trays like this. Instead of trying to make them yourself have a sheet metal job shop make them out of s.s. - acrylic and fiberglass weigh too much. Ask for beveled edges - will make scrolling easier. Mine are a little over 50" long x 10" wide x 3" deep and are designed to work with one gallon of working chemistry.

Well, if Bob doesn't weigh in to correct me, the ones I've seen in his postings seem to be as mine, the largest Cesco's available, and they are tight with 42" rolls. I need 2 gallons of chemistry in mine to get minimum coverage. frotog is probably correct that you may have to make your own a la Clyde Butcher.

Make a frame of wood, cover it with plastic and get to work. I hve used them like this up to 6' wide.

FWIW we used to make large troughs for "rolling" processing large prints. We made a frame of 2x4s and put thick vinyl into it and staples it to the frame.

I've never succeeded reliably in rolling and transporting mural sizes of fiber paper through 4 or 5 changes of chemistry without crimping, folding, or otherwise injuring the emulsion. RC plastics are easy to do though.

You can get a rough idea of what these guys are talking about in the beginning of this short video below:

I would prefer one large SS tray that drains out the bottom, so the wet paper does not need to be moved. The tray however would rock on a spindle welded on the center point forming a hinge so the whole tray will allow agitation. Timing pouring and draining chemistry is less an issue than crimping a large expensive sheet of exposed paper.

Unless custom, commercially available drkrm sinks will only fit two mural trays. Use the first for dev. and fill the second with stop. Have your gallon of fix ready to go after manually dumping the one-shot stop. Having one tray with a tap as suggested by Greg would lead to excessively slow chemistry exchanges which would introduce all kinds of unnecessary problems. Also, processing flat will inevitably lead to a crimped print - even if you're using just one tray - most likely during agitation and most definitely in removing the flat print from the tray. There's a reason to scroll - simple tools and a modicum of technique will yield the best results.
