I am using two modified Jobo 1500 reels in a rotary processor. Then needed to be cut in the center (so they are 'Minox-only' now).
I suspect Patterson reels could be also modified.

If the emulsion touches the spirals, there will be un-even development, so I rig up a little piece of springy plastic that keeps pressure on the film to push it to the center of the reel and expand it so that the base is in contact with the spirals.
