[Frameworks] looper question

Sun Oct 12 16:56:13 UTC 2014

How well are the splices made? If they're sort of uneven and bulge out, or
if there's any tape residue on that area of the print, that will cause
problems. Tightness of the film pack is also critical. If the film is wound
unevenly in any way that will cause problems, and if it's wound too tight
it can seize up. I would pull the film off, check the splices for dirt
buildup and residue, and wind it back on as evenly as possible.

On another one of these installations it was necessary to use a roller with
a counterweight to even up the tension, but that was basically to get MORE
slack. It sounds like you have the opposite problem, so you may need to
give it a tighter wind.
