Grimes Expert Film Handler Posts: 247 From: Lunenburg, MA Registered: Apr 2000 posted 08-13-2000 03:17 AM                        Hey there fellow projectionists I have a rather quick question - I have never seen or operated and Christie projectors other than the p35gps... Is there anywhere I can read or even see them or did Christie just make platters and lamphouses for the past thirty years? Any help would be great.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-13-2000 04:17 AM                     Sean, Christie's original version was simply called the P-35 and I do not remember the exact year it was introduced but I want to say early to mid 80's. It had only two timming belts in it and used a right angle shutter gear box and a reversing 1 to 1 gear set to drive the intermittant. The very first machines also used a Simplex E-7 intermittant instead of the ultramittant. Early machines had single lens mounts, a sound drum that supported only the outer edges of the film, and a very long straight gate, Actually, these older machines in general actually run better than the gearless version, and seem to have fewer breakdowns. The one problem was that the gears in the right angle shutter gear box are so small that they used to wear out fast. But no where near as fast as the present shutter belts(yearly). I suppose the biggest problem was that one could not tell when the gear box would wear out. At any rate there are a fair amount of these machines still in daily use that have the shutter gear box with the Ultramittant driven by the reversing gear set. I have one thats in the low 40's serial number range ant it runs great. BTW: These also have a two blade shutter.

I think that it was introduced as early as '79. We just took some out of a theatre a few months ago, and replaced them with even older Centurys. That tell you something?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-14-2000 08:59 AM                     Kevin, Actually the new machines with the single blade - double speed shutter have considerably more light than the older machines with the standard shutter. They also have no ghosting or shimmering problem either.

I do not currently service any of the new versions of the Christies. But the old bow tie shutters suck up a lot of light. Beven, I am sorry, and thanks for correcting me via email. It is nice to know that you lurk around here. But why won't you participate?  |  IP: Logged
