    Unicolor Motorized Base & Drum

    I have a friend who mentioned he had some old photo equip. his dad used at one time. Among the items was a Unicolor motorized base and a tube/drum of some sort. The base works. I thought, hmm, maybe I can do something with this to do just a couple of sheets of 4x5 at a time. I did some browsing re: Unicolor, and it appears there might be a cap or plug missing for the drum. One end has a funnel-like opening that appears to be light trapped and the other comes to a flat cone like shape with small holes in it. I'm thinking the funnel end is for filling and the other for emptying??? In any event, anyone know where I can find the cap/plug or have a suggestion for a work-around?

    What you have is complete. It's light tight as is. Theres no ribs to hold a 4x5 sheet in place so I'm not sure how you can make it work. Experiment some and see what comes of it.

    The tube/drum has a removable cap on only one end. I tried pouring water in the funnel (removable) end and all it did was pour out the other so I assumed it must have some sort of cap to use while filling. From research I gathered the drum was for prints, but I was thinking it could still be used for two sheets side-by-side with a round spring separator to keep them apart. Here are some pics. IMG 0199, on left, is the removable cap end.

    I used a drum that had a funnel so you poured the solution in, rolled it, and when you picked it up again it drained out the bottom. It was for paper processing one shot chemistry.

    The colour drums usally used on the likes of 70mL of chemistry for an 8x10 of paper. Ususally there was a cup under the funnel that held the small volume. Turn the roll on its side, and start timing. Turn drum up again at end and the small volume runs out of the drain holes.

    The Paterson tubes that I have has a plastic disc with a hole in the middle that goes over the end of the tube before the drain bottom is pushed on to make the light trap to cover the actual drain holes, and to let the tube hold larger volumes of warm up and wash water. Try making your own out of an ice cream container lid that you leave in a colour bleach solution, etc. to turn it dark/black. .
    my real name, imagine that.

    The motor will use quite a few other drums. A jobo 2551 or bigger for example. Can be found used. Plug the motor into a timer like the Gralab 300 and you've got most of an automated setup.

    Great idea on the timer. I have a Gralab and will give it a try once I sort out the drum issue. Thanks.
