quote: Bernie Anderson Jr You're talking about splicing the remaining reels on while the movie is running. How do you splice the remaining reels on while its spinning with out the print brainwrapping. Interesting idea.
Interesting, but not fun, and you have absolutely no margin for error. Make one mistake, and you're screwed.
One. You need enough film on the platter, so that its weight will pull the new film off your mut without the pack shifting. For me, that's no less than 3 full reels worth... and you need to get to this before the projector pulls much of it off. The more it removes, the lighter that pack is. By the way... Film Guard on the platter reduces friction. In this case, friction is your friend. If you need to, clean off the platter.
Two. You have to free-wheel the mut. No spindle keys, drive motors, and the like. It has to pull off easily. the clutched spindle on the Strong mut works ok, at least the way I do it.
Three. You put the feed platter in makeup mode, and run it manually from the mut. With the backpressure from the film it's pulling, the autofeed won't keep up... at least not with a Strong platter (it's only deficiency, I might add!).
Four. You (or at least I) wind the film ahead a bit, so it doesn't wrap while the ends are spliced together. After splicing, you run the mut control so the platter keeps up with the projector. The control will need frequent adjusting, as the diameter of the feed pack, and backtension from the feed reel changes. Because the larger outer diameter of the pack is pulling the film off your mut, you'll be winding the film onto the platter faster than it's being drawn by the projector.
Since I do my inspection on the bench and splice 3 or 4 reels to a large one, this is pretty easy for me. After the first reel goes on, I only have one left (on most features).
You can see this is pretty hazardous. If you were to splice the sound track on the wrong side, you'd be screwed, because there's no going back. If you splice something out of frame (which none of us ever do), you'd have to deal with that at some point. too.
The biggest risk is not having enough film on the platter to begin with. If you don't have enough film (weight) to pull the film from the feed reel, or if you overdrive the platter and pull the film too hard, it will go off-center, and you will be honest and truly screwed.
This is something that happens to me once or twice in a season... usually due to late arrivals or us changing the order of one of our doubles. It's NOT something I look forward to, or am particularly proud that I've figured out. By its nature, it happens with a crowd outside, and any mistake on my part means they don't get what they paid for. It's a tool you can use if you absolutely have no option. Personally, I wouldn't advise that you look forward to trying it.
