Author Topic: How many hours of 35mm film will an AW3 platter hold? Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 06-19-2010 09:48 PM                        When we do the Twilight/New Moon showing on 6/29, I'm considering building the prints together and just setting the cues to bring the lights up and down. I would probably use trailers to build a 10-15 minute intermission between the two. As a side note question, has anyone ever run an interlock this way? I would be interlocking 2 projectors.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-19-2010 09:56 PM                        Film is much thinner now. Should work OK.

This is where SPECO came up with their platter name "LP-270" - 270 minutes (4.5hrs) of film on one of their metal decks. It's quite common to see a double feature stacked on one deck. "Twilight" was around 130 min and "New Moon" was around 126 min. Then add your 15min trailer pak inbetween, and it's gonna be a full deck. I'd recommend having a film wrap made to go around that entire roll so that end will definitely not go loose on you since you're gonna be right close to that edge. -Monte  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 06-19-2010 11:22 PM                     quote: Monte L Fullmer I'd recommend having a film wrap made to go around that entire roll so that end will definitely not go loose on you since you're gonna be right close to that edge. http://www.film-tech.com/products/safetyring.html  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

It takes only 2-3 minutes to rethread...  |  IP: Logged Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 06-20-2010 01:01 AM                        @Manny There are actually several different reasons why I would want to do it. The main reason is I will have so many film built up at that time I may need it just so I have enough platter decks and centering rings.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 06-20-2010 01:45 AM                     Forgot about that safety ring thingey. Was thinking on something that didn't have to cost - like a scrap piece of film and wrap this around the print and tape the end down securely and write on the tape what the title is. Some M/O's have to think, "not spending money" when what you got will do justice. thx-Monte  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 06-20-2010 01:56 AM                        A piece of film or nylon with velcro won't keep a print on the platter, though. It can't prevent it from moving... at all. The Safety Ring keeps it on the deck. I should find some of the video I took when testing the Safety Ring before it was released. It took quite a shock and yet the print remained on the deck.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-20-2010 08:49 AM                     I agree on the F-T platter ring. Best thing ever made for platters. It costs far far less than just one lost show due to thrown print or a tail wrap. A film ring is still does not offer enough safety factor.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 06-20-2010 09:01 AM                        Agreed here too. We've done two movies on one platter here since 1980. The platter ring took at least 98% of the worry out of it. One thing to keep in mind though, those are fairly long movies and it's possible the Film-Tech ring might not fit (it extends into the platter about 1.5" all around).  |  IP: Logged Galen Murphy-Fahlgren Master Film Handler Posts: 405 From: Canton, MI, USA Registered: Oct 2007 posted 06-20-2010 09:54 AM                     If your platter is timed spot on (20 rpm high, 1 rpm low), you may want to slow it down just a touch. In my experience, the "ideal" timing settings will try to fling a print of that size at some point after the two hour mark. While a platter ring should prevent it going over the edge, it is still preferable to keep it from moving in the first place.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 06-20-2010 11:41 AM                     We did extensive testing of the safety ring with all lengths of films with the worst possible timing settings we could manage, and also with 70mm film. We were unable to toss the film, even when we went in and intentionally jacked the last half hour of a long movie into an "S" and a "U" shape around the brain.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-20-2010 08:25 PM                     Galen... If you time your platters as per Brad's notes on the "Tips" page it won't throw a print. If you time them the Christie way it will throw a print.  |  IP: Logged Carl Martin Phenomenal Film Handler Posts: 1424 From: Oakland, CA, USA Registered: Feb 2002 posted 06-21-2010 06:11 AM                        twilight is about 2:01, new moon about 2:10. i'm planning on doubling them on a platter without joining them, so they take up less space and i have more control over when the second one starts. of course i'll have to thread twice that way. i assume i'll have 4 different films playing that day on that screen so i won't have platter decks to spare. glad to have a safety ring.  |  IP: Logged Galen Murphy-Fahlgren Master Film Handler Posts: 405 From: Canton, MI, USA Registered: Oct 2007 posted 06-21-2010 11:32 AM                     Well, I don't have platters anymore, as I am out of the biz now, but in my experience running Indian movies, I found that Christie spec was a surefire way to throw long prints, and using the timing method from the tips section was not foolproof either. On prints in excess of 8 reels plus rolling stock and trailers, in order to prevent thrown prints entirely, I timed platters using the Film-Tech recommendations, then dialed back the high speed to about 18 rpm or so. This is just what worked at my building for me. I've never had platter rings, nor was it possible for me to get them. I think it would still be preferable for the print not to move, because sometimes even if the print stays on the deck, it can start a brain wrap, but I could be missing something.  |  IP: Logged
