For those of you who followed my "just couldn't leave it alone" thread, you alre ady know how adept and handy I am. I also relish the idea of using off the shelf plumbing supplies for film processing, rather than spend 10 times that at photo supply store.
I spent many hours in the archives looking for answers, but I still need some gu idence.
1. I visited the BTZS darkroom website, and I think I understand the theory. But one thing kinda disturbs me. All the talk about rigorous consistancy with agita tion during development, and timing the agitation to within seconds, and warning s about "over agitation"....then the BTZS instructions say "don't worry, just ke ep the drums rotating". Question: isn't a more methodical, consistent agitation system required with tubes? I do have an idea to build a motorized tube roller f rom an old 33rpm record player. 16 rpms would be easy to achieve, thus having th e tubes constantly rotating.
2. If you have made your own tubes, could you contact me and kind of fill me in on what materials you used? Thin wall PVC, or schd. 40? Or, if folks could sugge st websites that may have more specifics on building developing tubes.
Thanks
