Judy...I think it's Phil Davis who is the 'toobie' (err know tobe which
is your quest) He found that by using a small tube for 4x5 vs a tray or
hangers or tank that density was EVEN throughout. I assume this might be
extrapolated to your needed size by figuring the circumference (pi times
Diameter) and purchasing a PVC pipe @ a wholesale plumbing house.
Rotational speed would be important. I believe Davis says to roll it back
and forth normally ... it also uses a small amount of chemistry ... so I
assume it to be about 40 revs per minute (seems fast to me) and hence
you'd have to match that with a bigger drim and that gets more difficult.
Jobo processors solve that w/speed control.
I'm sure you'll more detailed info.
