Somewhere around here, someone had the idea of splitting some small plastic pipe. I tried it, slipped in four of my many screwed up negatives with these split pipe spacers (they clamp over the ridges real well) and shook the bageeses out of the tube while watching TV. nothing over lapped and the pipe did not come off. I put water in it and did the same thing. No leaks and no slippage. Took about two minutes to cut the little tubes. My hopes are up.

I am still trying for the rollers but until then hand rolling on the table is fine. the V thing sounds interesting but I would need to see one. I can't figure out how it would work.
