I have been using Jobo Expert Drums for 8x10 and 5x7, and I just got another for 4x5. I don't have a processor so I have simply been rolling the drum back and forth in my darkroom sink (which is empty). I have been thinking that for longer development times in particular, the temperature of the developer could change more than I would like. I tried letting the drum float in a water bath, but it seems to take on a bit of water, not in the development tubes but in the drum itself, through slits in the bottom. I have never used an Expert Drum with a processor but I am assuming this has some purpose. In any case, it makes rolling the drum a little wonky. Also, water could easily leak in the top, so this method clearly is not going to work.
Have any of you had similar questions about using the drum without the processor? How do you use your Expert Drum?
Should we call ourselves, collectively, the Drum Corps?
