Non reversing beseler drum basegreenspun.com : LUSENET : Large format photography : One Thread
I have recently purchased a Beseler motor base which I will use for 4x5 film processing with a Unicolor drum. My question is: this motor base does not auto reverse, it always rotates in one direction. Do I need to reverse the drum on the base during development? If I do, at what intervals? Any help will be appreciated. Thanks to the board for the eraser tip for four sheets of 4x5 film, I have already practiced my carving skills on some erasers and after a few attempts, I now have a great neg separator.

I've never tried a non-reversing roller; however, I'd expect some tendency toward streaks. I'd suggest end-for-ending the drum at least every minute.

I have the same motor base and have not experienced any irregular development with Arista 125 in D76 1:1 with presoak. I don't reverse the drum.

I have the same base and haven't experienced any streaking of Plus-X, Tri-X and Tmax films.
