I wrote one and it's going through a revision. I'll post here again when it's finished and if anybody wants to look at it (and comment) then I'd be glad to send it in.I have the SMPTE book but I find it offers too much for beginners or min-wage multiplex operators...most of whom won't be sticking around long enough to make it worth teaching projection in that much detail. ------------------
And, hey! Let's be careful out there. ~Manny.

"most film scratching happens by misthreading the platter; if the projector is dirty the film gets dirty but not scratched!"I must strongly disagree. I have seen this happen before with prints that are ran on reel to reel systems where there wasn't even a platter in the booth. Projectors CAN scratch film just as easily (if not easier) than a good platter, inparticularly if they are misthreaded, but even just from the projector being dirty. Why? Most *good* platters have keeper brackets on every roller. Take a Christie AW3R or SPECO LP-280 platter and you have keepers on every roller and no way to mis-align the roller that feeds the film back onto the takeup deck. It is very difficult to scratch film on these during normal running. Scott, UA made themselves a trainin' video back in the day. (Early 80's I believe it was.) The thing was incredibly long and every step was painfully demonstrated in real time. The only problem was that the camera angles did not show what needed to be seen, the shots did not match what the announcer was talking about and the techniques in there were just horrible. My favorite part of the video was when they showed how to make up a print to the platter. They had the roller on the MUT so low that the film was getting scratched over the edge of the deck while it was loading. I guess they were too busy shooting the video to notice.  (I'll have to try and dig that up and get a screenshot.)

Sure you can find a case in point on reel-to-reel scratching but I can find far more scratches in platter based theatres!Oh, and it looks like I just turned 1000 (posts that is) Steve ------------------

I can't remember how to do a screenshot, but here is a 6 second QuickTime clip from that booth training video of the film getting scratched because the rollers on the MUT were not set up properly and the film was not threaded through the rollers properly either.(Note the shoe polish on the edge of the print that was in an earlier part of the video! My how times have changed.)

The scary part is that you all know that sort of stuff happens!!! In fact, everything in there was a parody of real stuff.
