What I want to know is if anyone has had any luck with this and if so how. He said there was never a rotary base with his. And can I use it for 5x7 negs?

How necessary is the base?
Mark, From what I gather that your dad said, he was basically using the Unicolor drum in the same manner that BTZS tubes are used. They have been used by many over the years with good results.
