Tim,
Just in case you are not familiar with the Jobo processors, they are
available with a gizmo called a "lift" that essentially allows you to
quickly fill and empty the drums whilst they are in motion.
I was suggesting that the film should be washed (following dev and
fix) in the (rotating) drum on the processor through a number of
water changes, then the film should be removed from the drum and
dunked in some photoflo rinse before drying.
Does your unicolor base have bi-directional rotation - ie does it
reverse during processing? The Expert drums are designed to work
optimally for a particular speed of rotation and frequency of
reversing.
You'll probably get the best out of the drums if you use them on a
Jobo processor (CPA2 or CPP2) with a lift.
Cheers,
Clive
