    HC110!! Cheap as heck, can be diluted to any dilution from syrup, syrup lasts forever and has worked great in my rotary tank and hand tank systems! It is my go-to developer (I've even used it for paper in an emergency with good results)...

    Diafine works in rotary? I LOVE the idea of diafine and am actually a HUGE fan of acufine but found that acufine did not work well in my uniroller..

    I could never get HC110 to work but heck, i'll try again! I used to have half a dozen bottles of it and just swore it off (it's like molasses)

    Rodinal and Pyrocat sounds like the route I want to take. I've very familiar with Rodinal (Now it's called something else?) not familiar with pyrocat but am familiar with PMK Pyro which I _loved_. Awesome, thank you for the replies..

    Wildbill, I can't recall 'why' it didn't work (it's been years) but I do remember uneven development, even with a presoak. Could just be me.. It works for you? I must suck

    I use D76 1:2, Edwal 12, Microdal stock and 1:3, and Tmax 1:4 in both tanks and Unicolor film tank.

    Developers based on pyrogallol or catechol, especially in dilute solution and limited sulfite content, may not respond well to rotary processing. These developing agents are very sensitive to aerial oxidation. A rotary processor is constantly introducing oxygen into the developer.

    RE: HC110 - I have yet to have problems. Maybe the Unicolor rotating base is slow/gentle enough. I've used numerous dilutions (from B to H). I do drop the dev time by about 20% as per recommendations around the web though.

    EDIT: No presoak either.

    I don't understand your post since HC-110 does not contain either of the two developing agents mentioned. HC-110 contains Dimezone-S and hydroquinone which both seem to hold up well to aerial oxidation.

    I dont think I would use Acufine, or FG7 (if you any left) as the devleopmet times are so short you may get uneven development. I dont see any reason why HC 110, Tmax or DDx would not work in a roatery drum, I have used Tmax with good results.
