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.

Having seen my fair share of tail wraps, I'm curious why you'd want to run the risk of disaster, rather than play it safe and prepare them on individual platters? It takes only 2-3 minutes to rethread...

@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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

sure, i could do that, but then i'd have to be there to stop it, which is just one more thing to remember.
