Typically, when the film is dry, I set it to somewhere between 12:00 and 1:00 position. (No numbers or clicks -- Century SA-TA)If the film is FG'ed, it likes to be between 4:00 and 6:00, depending on whether it's Kodak or Fuji film. (Fuji, being a hair-bit thinner, I believe. -- Therefore needing a bit higher setting to get the same tension.) I've learned just to take care of it myself because most people just don't understand what it means. It's a mental bandwidth problem, I guess. PS: I have noticed that FilmGuard has a little bit of a "residual" effect. If you just ran a FG'ed print for a while and then you run a dry one, the projector STILL runs a lot smoother and quieter. You still get some dust but not quite as much as before. By the end of the day it does wear off, though

Sounds like the unsteadiness was printed in. Often such unsteadiness is due to the common practice of using a continuous contact printer for printing the short-pitch camera negative to a short-pitch master positive to a short-pitch duplicate negative. A pin-registered step printer should ideally be used when printing short-pitch to short-pitch. For a discussion of the "Optimum Pitch for Printing", see Kodak Publication H-1: http://www.kodak.com/US/en/motion/support/h1/sizes.shtml One quick way to determine if the unsteadiness is due to your projector would be to pull the aperture plate, such that you can see the corners of the print film perforations projected to the right of the screen. If the perfs on the print are steady, but the image is jumping relative to it, the projector is doing its job correctly. If the print film perfs are not steady, print lubrication and tension adjustment should help, unless the projector needs repair. ------------------
