Author Topic: Whats wrong with this picture Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 03-17-2003 04:55 PM                    I'm not sure I like the idea of the grooves flying by slapping the edge of the film that is taking up or working its way to the payout. I still advocate a platter disk especially designed for lifting off. All that is needed is a bit of modification to the hub and bearing arrangement, overall reinforcement, availability in several sizes so the smallest can be used, a special center ring that positively locks to the disk, and, for theatres which will be moving prints in a way that requires it to be carried on edge there could be an upper flange that locks to the center ring. This is basically combines the idea of the transport disk and the platter reel except that instead of laying it on a regular disk it takes the place of it and it need not be designed to run as a reel although that could be an option.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 03-17-2003 06:45 PM                        This sort of illustrates what kind of grooves I was thinking of (ignore the sawdust): The 90-degree corners at the top edges could be rounded if necessary, especially around the rim of the platter where fingers might come in contact while in motion. Would film catch on channels this small? What if channels are filled in during operation with either "fillers" or part of the clamp device?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 03-17-2003 06:54 PM                     Moving prints with 3 clamps sucks because one person has a clamp they can put their arm under (to make sure the print doesn't "fault"), but the other person has nothing to grab onto but the film. I always used 2 clamps, but if it was a large movie or I thought it would loose would use 4. Never ever odd numbers.  |  IP: Logged Daryl C. W.

Dave, that's the same thing I was thinking of. Provided the both edges of the entire groove are rounded or filed off I don't see there being a problem. It's only when there are bumps or burrs for the film to catch on that you end up with film bounce.  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 03-17-2003 08:15 PM                     I've got a replacement disk being shipped to an install i'm going to this week. I'll try to bring the bad disk back (it was going in the dumpster) and have our machinist look at it. I'm not sure how he could hold it on the mill to do any machining though. Don't the film clamps come in sets of 3? Rick  |  IP: Logged Daryl C. W.

Clamping it down would be a challenge though.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 03-17-2003 09:14 PM                        I move 2 hour + prints like that all the time by myself, provided that I feel that they have been wrapped tightly enough. When they feel even a bit loose, I get help. The problem's not putting the print down. That is the easy part. The biggest problem is picking the print up and making sure that it maintains its structural integrity. Once the print is vertical it's pretty much good to go. I would never attempt this with a print the size of God 'n Generals. The biggest print I moved by myself was Pulp Fiction. I am not advocating or promoting moving prints by one's self without clamps. That's just the way I do it sometimes. If you only feel comfortable moving 4 reel prints with 10 clamps and 6 big strong men to help, then continue doing it that way. It's your booth.  |  IP: Logged Michael Cunningham Expert Film Handler Posts: 186 From: Anchorage, AK Registered: Nov 1999 posted 03-18-2003 09:41 AM                     The only issue I see with moving prints by use of the 'Interlock' method is when do you find the time to do this? Since the final show of the print to be moved that night will undoubtedly be playing at the same time as the receiving platter's show, do you have to stay late and run an extra show? Or do you have the 5 deck, double variac platters at every screen? I love interlocking and horrifying newer Projectionists with it and this sounds like an ideal way to move prints about, but I just can't see how to accomplish it when the receiving platter's accumulator is already in use. - Mike  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 03-18-2003 09:52 AM                        I recall some companies are making "platter disks" that are thin rigid doughnut-shaped disks that can be placed on the platter when a print will need to be moved. The film is wound up normally on top of the disk, and the disk is simply lifted up with the film on top and transferred to another platter. Who are the manufacturers? Kelmar? Goldberg? Speco? Stuart A/V? Others?  |  IP: Logged Carl King Expert Film Handler Posts: 199 From: Saint John, New Brunswick, Canada Registered: Mar 2000 posted 03-18-2003 10:17 AM                     what's wrong? Everything. Projectionists should not be moving prints by themselves unless the print is clamped. An unclamped print can be moved by two people quite easily. The clamps are provided for a reason. USE THEM, PLEASE!!

USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 03-18-2003 01:29 PM                        Michael--I probably wasn't clear earlier with the "moving prints by interlocking" post. You don't actually interlock anything; the platters just need to be modified with 2x 35mm rollers on 70mm shafts on the payout side (think AW3 here) so that two different films can feed from one 3-deck platter. If the interlock rollers are lined up correctly, you should be able to feed one (of two) films from a given platter into another (non-adjacent) house. Essentially, the print "move" would be done as the films run on the first show in their new locations. It really only works right if you are moving only one print or swapping two prints between auditoria.  |  IP: Logged Don E.

Lucas George, the projectionist in the photo, just sat through the entire directors cut of (insert "Title "of your least favorite movie here) and he took the personal iInitiative to send the the film back where it should have originally been deposited , namely, the good ole dumpster back behind the theater. "Boy that sure felt good" he was heard muttering as he headed off to the snack bar for a Coke. My inserted title is "Heavens Gate."  |  IP: Logged Patrick de Groot Expert Film Handler Posts: 161 From: Sprang-Capelle, Netherlands Registered: Apr 2001 posted 03-18-2003 02:31 PM                     Moving prints without help isn't that difficult providing the takeup platter has winded the film tight together. We have to change films frequently and since their is only one projectionist at a time it is common practice in the 5 screen theatre I work at. Large prints are carried with 2 persons if possible) on a rectangular plank with three holes for the ring. Sometimes however I have carried HP and LOTR serveral times myself. I let it slowly fall over the border of the platter while holding it up. You should pay attention to the center ring. If that one slips away... btw we don't even have clamps...  |  IP: Logged Jean-Michel Grin Expert Film Handler Posts: 222 From: Geneva & Lausanne, Switzerland Registered: Jul 2002 posted 03-18-2003 02:57 PM                        quote: I recall some companies are making "platter disks" that are thin rigid doughnut-shaped disks that can be placed on the platter when a print will need to be moved.

Stuart A/V? Others? Goldberg make this type of disarmable reels. In ours multiplexes we just use one "half-reel" (a plate) to move the print from one screen to an another. The most important is to not forget to attach the tail of the feature with adhesive tape, and remove it when the film play in a another auditorium I let you guess what could happend if you forget that... at the next oportunity I will try to take a picture an place it here.  |  IP: Logged
