On the MUT a light under the table with a translucent window is handy when making splices. But for the love of God. Put a switch accessable from top side of the MUT, so you don't have to crawl around on the floor to turn it on/off. [Big Grin]

I'm not crazy about the multiple roller clusters on take up.
Maybe a slide bar assembly, like the Speco platter with a spring loaded pin that locks into a hole in the slide bar? That seemed pretty durable.

Also make sure that the payout provides at least a SMALL amount of back tension on the film, so you don't have the platter paying out faster than the projector can take it up (read Brad's review of the original SPECO payout review). Also, please please, make sure that in the payout that you don't have to "thread" the film underneath anything, like the Strong or unmodified SPECO pay outs. I do like the idea of rollers instead of just posts around the payout though.

I am not a fan of the internal drive wheel because if for some reason the platter deck becomes warped it hits the top of the drive spindles as it turns.

Bring up the payout directional roller so it is not at the very bottom of the tree.

I don't see how the connection from the platter to the MUT is done, but I'd like to suggest NOT having to plug the MUT cable in at the motors, as is done for Neumade/Potts. Having that cable hang down could mess up the decks below. I would prefer a MUT that plugs in at one place below the decks, like Christie/Strong AP platters.

MUT will plug in at the base of the column. Non-reversible, keyed AMP plug. The plug for the failsafe interlock will also be located there. All cover plates with plugs will be removable with screws (not rivets) for easier access.

There's nothing to grab onto for moving the brain. I like Kinoton's IMAX brain with the "fence" instead of using posts or rollers. People misthread on those, but a 180 degree "fence" around the backside would not only prevent that from happening, but also give something to grab on to.

We were thinking of under-cutting the block holding the rollers to give you a sort of handle, with your palm resting on the top of the rollers and fingers protruding into the undercut block. The perimeter fence would require two hands to lift it straight up.

Speaking of IMAX, what is the opinon on staggering the decks say 10-20 degrees side to side like an IMAX platter? It would give easier access to the feed plates/platter decks but increase the footprint.

Just out of curiosity Brad why do you want black rollers instead of grey? For those of us who don't filmgaurd all our prints (yes, we still exist) having the rollers a color other than black makes cleaning them much easier.

Please don't stagger the decks. 52" decks are fine so long as you don't make the top deck any higher than an AW3.

Any color roller other than black over time, with or without FilmGuard, will discolor. Black doesn't. The rollers continue to look like new 20 years later. It's a cosmetic thing.

Does the industry really need full 52" decks? I don't know about everyone else, but trailer placement has become a big issue with the distributors now, so it seems we're always changing trailers, sometimes simply rearranging the order because of a request by a distributor. Shorter people seem to have a tough time reaching in there. Could we measure "LOTR" and just add an inch? [Wink] I think I would rather be forced to have an intermission for the very rare 3 hour plus movie, but have it easier to reach in there to change/add trailers, snipes, etc.

I prefer the extra capacity of a standard 52" deck myself over a 48" deck. Anything smaller wouldn't work on those long movies, and you're only saving 2 inches. At that point, tell the short projectionists to use the bottom two decks on trailer changing days. It's good to use that bottom deck from time to time anyway. [Wink]

the staggering of the decks would allow better access of each larger deck for trailer changes I kind of like that idea

Brad,
I have to chuckle as you keep asking for an AW-3 [Big Grin] . Why not just stick with the real thing in the first place. Its already proven, tested, modified and has an excellent track record and its your very favorite platter [thumbsup] . I for one don't need any more new equipment that hasn't been field proven and that I may have to waste time going out to make warranty repairs to.....

Since Mark brought it up, I like the brain on the AW-3 really well. Extreamely easy to thread. No "brainwork" required!

Mark, you are correct I am perfectly happy with the AW3 as it stands right now. However the guys at MIT have already made some improvements to their design over the AW3. I just don't want to see something done that will make me continue to prefer the AW3, when they are trying so hard to improve on something that is already an outstanding design. If these guys didn't truly care, they wouldn't be here asking everyone's opinions.

Not to steer this thread off-topic too far, but lets say you are a die-hard Simplex man. Are you saying that you would not consider the Apogee projector simply because it has not been field tested and proven for many years, even though we all know it is a great improvement to the Simplex on many levels? That's just nuts.

Rollers should be conductive to provide a path to ground to help dissipate static.
