hmmm... interesting.... i've checked all the splices. clean, smooth, double spliced, no residue or tape goo... the projector does not leak oil... and i haven't had any seizing problems.
sadly it is not a motorized looper... i almost got one of those, but it was booked before me.... so it's rollers are passive and the loop is being moved entirely by the projector. i do have one more print... clean and never before used.... but i'm not sure if this looper has enough diameter to handle more film.... so hmmmm.... my guess is that the tightness of the loop itself is uneven... so.... i think i will add one more wind.... and if that doesn't do it.... then i'll take the whole thing off, inspect the film, and reload. for those of you who have used these, or other styles of loopers.... does it usually take a few days to find the right balance? or is it possible to get it working at the initial time of install? xoadc On 2014-10-12, at 2:04 PM, Julian Antos wrote: > Running anything over 10 minutes I would recommend using a failsafe system or > have the projector under constant surveillance.
