I have my omega pro lab fastened to an old tv cabinet, I had to firm it up a bit and put on bigger casters but it works fine and the shelf and cabinet provide plenty of storage.
I use a regular kitchen timer for film development, i keep this in a ziplock bag that has a magnet inside which I stick in the fridge, the ziplock prevents moisture or chemicals from seeping in to the buttons (learnt this from ruining an expensive timer when in college). I use an old wall clock for print timing.
I built a sheet film drying cabinet from a plastic storage bin, used duct tape for the hinges. I use a quarter from a furnace filter on the bottom to filter the air that passes through holes I drilled in the bottom, two pieces of dowel to hang the film clips and an aromatherapy fan thingy that draws air over the film. I built it for my 4x5 negs but it can handle 8x10 negs too.
I built a led safelight from a light I found in the car section at wally world, it runs on 12v and so I got a psu from the thrift store, total cost under $10.
I love the us plastics catalogue! I keep looking at there poly tanks and thinking some 1/4 inch threaded nylon rod, some 1/4 inch i.d plastic tubing and some plastic sheets could make a nice basket to go inside one of those tanks and make a nice print washer

.
I also keep my mixed chemicals in water bottles afer my wife has drunk the fancy icelandic water from them!
best regards
Andy
