Author Topic: Strong platter help, problem with take up. Matthew Stevens Film Handler Posts: 37 From: Colorado Springs, Co Registered: Jan 2004 posted 05-04-2004 01:08 PM                        We were running a print from the top to the middle platter, and apparently the wrap is very loose on the up take. We have strong platter with potts brains (or something like that). We think it could be something with the brains but not for sure. Anyone have something similar? I also have a question about a douser (I can't spell, sorry) plate that keeps sticking on the opening, I cleaned it and it works for a while, I also sanded it down a little. Anything else I could do? Thank you for taking time to help.  |  IP: Logged Chris Hipp Phenomenal Film Handler Posts: 1462 From: Mesquite, Tx (east of Dallas) Registered: Jul 2003 posted 05-04-2004 01:26 PM                     the changeover model would help.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

If the latter, which model projector and changeover?  |  IP: Logged Paul G.

It sounds like a timing issue to me, possible a motor tracking pressure adjustment. Remember, those platters are variac based. The take-up sets the reference for the payout speed. The take-up will always be slower than the feed-out because of a ballast resistor in series with the motor on the take-up mode. That allows a little better headroom so the pay-out can run a little faster when the phase control or micro switch closes. As far as the douser is concened - if it is a "Zipper" such as the Century used, the cable gets a little sluggish. The ball and spring may also be set too tight. Or, someone used too much WD-40 to free it up once before. The more you use WD-40, the more frequently you have to use it. A good cleaning job of the cable, tube, ball, and spring shopuld fix the problem unless the tube is kinked. Check for build-up of crud in the douser slides if you have a Century, Cineshittie, Brenkert, Etc.  |  IP: Logged Dominique Replogle Film Handler Posts: 61 From: Highland Utah Registered: Apr 2004 posted 05-04-2004 07:02 PM                        For your douser problem, try cleaning the slides realy well and aplying new grease.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 05-04-2004 08:40 PM                    Grease?

We grease ours. We have a CDC 15/70 with dousers powered by the air compressors.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-04-2004 08:53 PM                     "The more you use WD-40, the more frequently you have to use it." I just gotta get T-Shirts made with that slogan _________________________________________________________________ Steve, If you'd take 4 days off and come to Utah I can show you the CDC dowsers and why they need to be greased . And a few other interesting things not film related.

People who have compressed air C/O's now have their own forum.  |  IP: Logged John Walsh Film God Posts: 2490 From: Connecticut, USA, Earth, Milky Way Registered: Oct 1999 posted 05-04-2004 10:05 PM                     Matthew, are you saying the platters used to wind tight, but suddenly started winding loose? We have Strong AP platters. From what I can see, they all just wind film loose. People have hung weights on the carriage to make it wind tighter, since prints were too loose to 'trust' sliding off to place on another deck.  |  IP: Logged Dustin Mitchell Phenomenal Film Handler Posts: 1865 From: Mondovi, WI, USA Registered: Mar 2000 posted 05-05-2004 08:56 PM                     Is the problem just with the one deck or all decks? Did the print become damaged in any way-moore specificaly sprocket damage? Or perhaps there is a static problem? If you're not sure about it being a print problem you can always swap prints and see if the problem persists.  |  IP: Logged
