well done youngrichard! I like the paper shimming.
Steve knowing your skills in this area you'll find it kid's play and well worth the effort. I got mine done by someone with a laser cutter that cut plastic. Using pieces of both black and white plastic I find the paper slides easily and the guides for exposing each section a inch at a time show up very well.
Well. I have a laser cutter too!
Thank you for the plans. I have a few more weeks of night school left but after that, I intend to make one of these. There is a board we have that is dark on one side, light on the other so I can use the same material and simply flip it over to use the lighter/darker side where I want it. I have always wondered if doing test strips "across the board" of the whole image was giving me good cues about the printing I want to get. The way you explained this and its use makes much more sense to me and allows me to pick where I want to get a test strip and therefor get an accurate starting point to my printing. Having a home darkroom, albeit small, works well but works better with efficient tools. This is one such tool that I intend to get some good use out of. Once again, thank you.
Thank you very much for sharing the design Ralph. I'll make mine with foamboard & tape, I'm not good with handtools.
I made something similar some time ago from foam-board and hot-glue.
I found the corks from sherry bottles (they have a 'bulb' on them) make good handles - just hot glue the cork end to anything that needs a knob.
Durst made a version that had a sliding cover over the exposure slot: the cover had a pin you pressed into the paper and this advanced the paper under the slot each time the cover was moved.
