I think a combination of materials would be nice.Although the clasp in "D" is secure, it seemed that you had to bend it out a significant distance for it to unlatch. "A" seems like one of the better choices to ensure that reels comes with the pin holes lined up. "B" still has the chance of not having any holes lined up for breakdown. I have seem a few times with "C" that the reel has snapped off at the center leaving just the fastener. Also, fasteners "C" and "D" require that you flip the reel for final separation. As far as the plastic is concerned, I would vote for either "C" or "D". "A" and "B" are very soft and if they get warped from storage, then more care needs to used during buildup / teardown because you are having to compensate for warpped plastic possibly scraping against film.

Has anyone ever seen a split reel that will work on a Christie MUT? Neither the Goldberg nor the Neumade ones have the hole for the "drive-dog" (and only the 4" cores have this hole, anyway). As a result, it takes significantly longer to break a film down onto cores, as one must first break it down onto house reels (6000' or 2000') and then rewind it onto cores on the rewind bench. I suppose one could drill a hole into a normal split reel, but not everyone has a drill in the booth.  Even in a reel-to-reel booth, it can be annoying to deal with film shipped on cores, as one must have two good split reels (most places are lucky to have one) to take up on, unless one wants to rewind everything again after the last show. Why do Christie platter MUTs use "dog drive" anyway? Obviously it's needed for 1/2" shaft reels, but why didn't they use the standard "key"-type drive for the 5/16" reel shaft? (obviously, the shaft would need to be re-designed, as the single screw that holds it in wouldn't work if that shaft were keyed).

The physical properties of plastics can also vary with temperature and age. How do the various materials hold up when stored and shipped under very cold (sub-freezing) and very hot conditions? Plastics containing solvents or plasticizers may become brittle with age. Finally, the plastics should not "outgas" chemicals that may harm the film during long term storage (e.g., PVC is a no-no). And in an ideal world, plastic reels should be made of recycleable materials.------------------ John P.

I like reels C and D; however there is nothing wrong with A and B provided they aren't the flexible variety and they have the proper cores, which doesn't happen often.Anytime I get the C or D reels with 3 hole cores in them, I swap them for the two hole cores I have on hand so that I am prepared for the more common A and B type reels with two hole cores leaving no hole for the drive pin on my MUT! This morning I had to build 8 Legged Freaks and it was on A reels with cores that don't have holes at all, they have 4 wide tapered square openings.......the point is these reels are designed to locked together in a circular hole. This combo I received today fell apart when I picked up the reel. Some of us projectionists should go get jobs wrapping reels, that's the only solution I see to the problem.

Scott,Just about any well designed make up table will have a drive dog for breaking down film. The key is not designed to take too much torque. From shipping reels this is even more true since their keyways are often just sheet metal or other thin material that can really cut into the key itself. I believe on the Christie MUT, there are two tapped holes near spindle that will like up with the typical dog pin on a split reel...put the split reel on the MUT...screw the split reel to the dog plate and away you go. One of these days, I'm gonna try it myself! Steve ------------------ "Old projectionists never die, they just changeover!"

As Steve Guttag noted, shipping reels need to meet the specifications of standard SMPTE 192-1997 to properly interface with rewinds, make-up tables, and projector spindles/magazines. Before any design is finalized, it should be tested on the wide variety of equipment the reels will be used on.Copies of standards may be ordered from the SMPTE: http://smpte.org/smpte_store/standards/ BTW, the standard for the cores used by the labs is SMPTE 37M-1999. If you are using the cores as the reel hub, you need a copy of this standard as well. ------------------ John P.

Since my last visit, I have done a bit of research. First off, I WILL be making an adjustment to the "sharp edge" of my reel. I contacted Christie (Thank you, Brad) and they were kind enough to forward drawings of the drive pin in question. I am currently waiting for a physical sample. During my correspondence with Christie, we concluded that the "difficulty" of using the Transfilm reel with this MUT, stems from the lack of a "through-hole", when the reel is mounted onto a core with only 2 holes. (those cores are no longer being manufactured, yet I realize there are plenty in circulation) Here comes the fun part. The drive pin on the Christie MUT, is an aluminum shaft with 3/8 in threads, that stands off the plate, 1 3/8 inches. Christie has assured me that the length of the pin, "has no bearing on ANY functional aspect of their equipment, other than to obviously "drive the reel." " I won't insult you, by suggesting that you merely cut off the additional length, (in order that the drive pin stays beneath the middle of the core) even though Christie told me it WON"T affect any other aspect of their machine. For those of you that may be interested, I am hoping to make available shorter versions of the drive pin, that can be exchanged for the current pin. (simply unsrcrew the existing, and replace with the new) Ultimately, in trying to design a reel that is "universal" to existing 2 or 4 hole cores, I did not take into account that drive pins extended all the way through the reel. Lastly, The suggestions of consulting SMPTE 192-1997 was rather ammusing. Sure looks to me like a "KEY WAY" is called for on 2000ft reels. They even give dims. Why is there even a need for "drive-pins???? Anyone care to enlighten me??? Regards, and thank you again for your input.Helmut E. Dorausch Transfilm Inc.
