Author Topic: MiT platter design review Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 01:03 AM                     Steveo, you're missing the point. Bevan has the opportunity to take the best aspects of all the platters on the market and incorporate it into one. The AW3 is not perfect, but it's awful close. MiT could've outdone it without too much effort, but they haven't and I was hoping they would produce the platter to purchase. Oh well. So does anyone know if the motor have to be disengaged for breakdown or not?  |  IP: Logged David Yauch Expert Film Handler Posts: 206 From: Mesa, AZ, USA Registered: Oct 2004 posted 01-03-2005 03:33 AM                     Brad from the looks of it, the only suggestions of yours that haven't been implemented 100% have been the black rollers, vertical MUT(which is on the "to-do" list), and the lessening of the take-up rollers(which have been modified to swing out of the way, though we have yet to see a pic). Other than that a LOT of improvements have been made over the AW3. If MIT provides a vertical MUT, would they then be the platter of choice in your opinion? It seems that that is just about the only thing left.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 04:38 AM                     Nope, there's the flimsy center rings that I pointed out at ShoWest, the brain perimeter rollers, and I don't know if I like the idea of rollers swinging out of the way or not. I'd need to see it's implementation. But yes, it *could* be the platter to have...we'll see once they get the bugs worked out of it.  |  IP: Logged David Yauch Expert Film Handler Posts: 206 From: Mesa, AZ, USA Registered: Oct 2004 posted 01-03-2005 04:44 AM                     Fair enough, although the brain is sounding better than the AW3, especially since it seems like it will be easier to avoid dumbass projectionists threading on the inside of one of the posts like we get with AW3s. Bevan, post the damn picture already, I'm growing impatient! Just kidding. But seriously, my curiosity is getting the best of me.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 04:59 AM                     Anytime there are rollers (or posts) around the brain, misthreads can and will happen. I have also seen a movie jump over a roller on a Strong platter and cause a brain-wrap in the last part of a movie (no way it could have run that long). At least the Christie posts are pretty tall and that can only happen during threading. The MiT rollers are short and until they implement the "fence" idea like in Kinoton's IMAX platter brains, it can happen.  |  IP: Logged Bevan Wright Expert Film Handler Posts: 176 From: Fountain Valley, CA, USA Registered: Sep 2003 posted 01-03-2005 09:22 AM                        Clusters swing 270deg out of the way against the back of the column. Shows the round MUT plug, resetable breaker and two pin interlock for failsafes.  |  IP: Logged Jason Black Phenomenal Film Handler Posts: 1723 From: Myrtle Beach, SC, USA Registered: Nov 2000 posted 01-03-2005 11:21 AM                        That 'arm' under the deck is ala a Christie unit, correct? Pardon my ignorance.. it's been YEARS since I've seen, or worked with, a Christie platter... and, for the life of me, I can't recall what function it serves... And, as others have said, that's a TON off rollers on the tree... I see the potential for misthreads with such a large number of rollers..  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 04:10 PM                     I can tell from the picture I don't like that "swing-away" concept at all. That is just a film damage incident waiting to happen. It's no different than the early SPECO LP270s where you had to make sure the rollers were turned a certain way so they would be "out of the way" of the film path...but people scratched tons and tons of film on them anyway. Bad, bad idea. Also the lower roller that receives film from the projector is too high. That's a major twist going on there, and not very gentle on the film. quote: Bevan Wright Shows the round MUT plug, resetable breaker and two pin interlock for failsafes. On the flip side, these items are well thought out.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-03-2005 06:35 PM                     I have some customers that can't stand the take up roller slider concept (anyones) so separate rollers are a plus for them. I agree, though...the potential for misthread or rubbing the film over somthing increases the chance of film damage dramatically.

It is pretty difficult to misthread our design .... fact is that you can only do so much to equipment then you need to have some level of competence in an operator. (I have yet to see an automobile that someone cannot crash. ) Steve also made the point that there is no sense in duplicating 100% something that already exists... we took the top 15 or so issues/complaints and are addressing them in our design with the input from the industry. We appreciate all in the constructive input.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 08:19 PM                     Bevan, you can get your point across better if you don't conceal it in pretty verbage. Please allow me to assist. quote: Bevan Wright we took the top 15 or so issues/complaints and are addressing them in our design with the input from the industry Translation = "screw it, it's good enough". ----- I've seen FAR more damage to film ran on platters with permanently mounted takeup rollers due to misthreads than I have seen problems regarding a pin on a sliding track design. Besides a misthread = $3000 print. A replacement sliding bar of some sort is (or should be) under $100. And even if you had to replace the slide bar every 15 years, how many times a year will a print get damaged because one of the candy counter kids got confused as to which rollers he was supposed to run the film over or not??? Do the math. (Heck, for the savings in 6 extra rollers, you could toss in a spare slide bar with every new platter.) Sure you can only idiot-proof a piece of machinery so far, but the idea is to idiot-proof it as much as you can, which has not been done here. This should have been one of the "top 15". By the way, your "swing away" design prevents a top feed on takeup. Not every theater has the return film running next to the floor. The two rollers that have been swung out of the way are now in the way. I have asked this a couple of times now...on breakdown are the motors pulled away from the platter deck or not? Please answer this. There are enough crappy platter designs on the market right now as it is. Please don't go adding another one, further giving platters a bad name.  |  IP: Logged Bevan Wright Expert Film Handler Posts: 176 From: Fountain Valley, CA, USA Registered: Sep 2003 posted 01-03-2005 08:35 PM                        That is not what I meant, we are very open to suggestions and are keeping an open mind - a slide bar design was just discussed today as a matter of fact. Teardown can be accomplished either way with the motor engaged or disengaged, I did respond to this in an earlier post.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-03-2005 08:43 PM                     Ok, good to know. I must've missed your first response on that. (Hopefully the manual recommends against pulling the motor away to prevent film damage from occuring.) I presume the backdrag is the same as on an AW3 or SPECO? What about the rubber center rings? When will these be made sturdy like Christie's or SPECO's new rings? Those bendable rings cause cinch scratches during print moves and breakdown, you know. ...and don't forget the latch.  |  IP: Logged Andrew McCrea Jedi Master Film Handler Posts: 645 From: Winnipeg, Manitoba, Canada Registered: Nov 2000 posted 05-15-2005 02:13 PM                        With that top picture that Bevan posted of the platter with no discs on it... What are those arms to the right, that would be directly under the disc, for? Has anyone used MiT equipment yet, and what do you think?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-15-2005 02:20 PM                     They are the takeup speed control  |  IP: Logged
