The Nikor reel comes with a metal band to keep them all in place. Or are you saying there would be so much drag it would collapse the sheets and let them pull out along the edges and get all crinkled in together in the cage?
Humm. I didn't realize there was a keeper band. That might work. But a Nikor tank isn't any cheaper than a Photo-therm insert. It just has more capacity.
Cutting up a Patterson us exactly what I have been thinking about. But I would sure like to see one someone else has done first.
