That's what I call myself and my brother-and-law. I went at and cleaned up the winterizing grease on one of my XL's today and decided I'd run some film through it. Well, exactly 29 years from my own debut, I have run a 35mm cinema projector. Pretty cool. The dumb and dumber part was trying to figure out how to spool my selected victim (Shelley Long - Outrageous Fortune - bad career move, leaving Cheers?). I could not get my mind around how to run this through so it wasn't upside-down  !
So I ran it through right-side up  ! Looked good (no lamps yet, so I could see), but now I was running backwards ! Well, great, but how in heck does this thing read the sound ? I actually said to my brother-in-law (I'm dumb, he's dumber)
"What in hell, does this thing have some kind of weird lens or something?" So I grabbed a flat lens, cleaned it a bit, and looked through...........OOOOOHHHHHHHHH, I get it! Where is the little "smilie" for getting conked on the head with a hammer? Anyway, I learned that film properly threaded doesn't pull the picture out of frame like if the soundtrack is reversed. I also think I put the wrong oil in the projector. :hammerhead: Does anyone know who sells Strong parts and oil etc. here in Ontario? Thanks for all your help, I really appreciate it. Next up, wiring up the exciter lamp and AM transmitter (can you hear it? ..."this theatre is Radio-Active!"  )------------------

The picture will actually be upside down when running forward if you are looking at the apeture. The lens flips it.You're doing okay, just keep at it! I'll try to check back, but I am currently being scowled at because the new ceiling fan in the bedroom ain't turning yet. Some people just can't appreciate the need to take one's time with an equipment installation! Russ

Oh, I don't know, Barry. I might be winning the race to see who's wife will let them put a screen behind the house. I think your planners will be easier to convince than mine. Your website is impressive, the ideas just what you need to thrive. At first I just wanted to learn, but that's never enough is it? Making those machines go is a powerful thing, especially when the "local" drive-in doesn't give a sh** about presentation. Bet you beat me though! Yes, it's fun. What is the little dial on the gate numbered 1 to 5? Now, if I can just convince the wife, we have the hydro, a big enough building (workshop) for a concession and enough room for 3 screens  . I agree, industrial-park drive-in's never had much of an atmosphere, but it's nice to hear of somewhat friendly planners, some municipalities seem to regard a drive-in as undesirable. The thing I like about what you're doing (and I'd like to do) Barry is who in hell builds a drive-in theatre in 2000???!!! Remember, the world has enough lawyers, doctors etc. We need more QUALITY movie venues. ------------------

35mm release prints are well standardized by the Society of Motion Picture and Television Engineers (SMPTE). Because of this, you can (almost always) count on the following:The image will be upside-down in the projector gate. The projector lens "rotates" the upside-down image 180 degrees during projection, making it right-side-up on the screen. The emulsion side of the print will face the lamp. The base side will face the projector lens. The image on the print itself will "read" correctly if you look at it from the emulsion side. The analog soundtrack will be at the left hand side of the image. Sound film should run 24 frames per second, or about 90 feet per minute. The projector will pull the film down 4-perfs at a time, usually using a 16-tooth intermittent sprocket rotating 90-degrees per frame. A "Geneva" intermittent is driven at 1440 rpm (24x60=1440). The analog soundtrack will be on the outboard side of the projector (toward the operator) as you thread. The analog soundtrack will be printed 21 frames ahead of the corresponding picture frame. Keep these simple guidelines in mind, and the film will be right-side up on the screen, with the proper frame rate and the sound in sync. ------------------
