70mm : Movies :: 120 : Still Photography I use a Rolleiflex camera that takes 120 film so the scale is not totally alien to me. (120 roll film is approx 65mm wide.)
One cool thing about the Kinoton is that, when the projector starts up, the intermittent runs continuously until the machine comes up to speed. Then it starts moving in steps.
For some reason, the size of the loops seem to change a little bit once it starts up.
A question: Because the projector is driven by stepping motors instead of belts and gears, does this make it impossible to "bottom out" the intermittent?
On some projectors, if you thread way out of frame, with the framer racked one way or another, it is possible to get yourself into a position where it's very difficult to reframe.
Pressing the frame button on the Kinoton simply advances or retards the step of the intermittent drive motor. So, theoretically, one could roll the framing continuously without ever bottoming out.
Is that true or is there a limit to watch out for?

It's a lot more difficult to get the wide film to bend around the rollers and sprockets. Not hard, per se, but you can't just twist it around the corner like you can with 35. You have to, sort of, coax it.
The Kinoton platter is a 4-deck model. There is less than a foot of headroom from the top of the film roll to the top of the arm that holds the deck above. You have to take out the platter ring before you place the brain or else there isn't enough room to get the ring out. If you are threading the bottom deck, you have to get down on your hands and knees and stick your whole head into the gap to reach the center. It's like trying to cast a fishing rod while standing inside a phone booth.
When I worked for Cinemark, we would occasionally have contests to see who could thread a projector the fastest. I once threaded an entire projector in less than 90 seconds. It takes me four or five minutes to thread up the 70mm.
Okay, I'm not trying to thread fast. I'm trying to do it right. Speed isn't the point even though I'm sure I'll get better with practice. However, when I came in today to thread up the movie at Mercyhurst, zip, zip and I was done.
It's sort of like the way a baseball player warms up with a donut weight on his bat. When he takes it off it's a lot easier to swing the bat.
8mm film would seem like dental floss to me, now!

There are three movies, played in rotation, on the hour. They average 45 to 50 minutes long.
If there are no tickets sold, the theater will be dark for that show. We don't even thread the show unless there is somebody to watch. If somebody comes, we thread up and run. If there is nobody by ten after, we call it.
Yesterday, we had a mom and two kids come to see "Volcanoes of the Deep" but the next scheduled show was "Beavers." It was the last show of the day so I made her a deal. IF nobody showed by ten minutes after, I would play "Volcanoes." Nobody else showed so I did play the movie she wanted.
Long story short... I don't try to thread too fast and I make sure I have double checked and triple checked but, due to the way business is, right now, I might have to run at the last minute.
Business is slow, right now. When the weather warms up and more people come out to Presque Isle, there will be more traffic and shows will run closer to schedule.
Until then, nobody really cares of a show starts a couple of minutes after the hour.
I don't want to thread fast. Let's say I want to thread "efficiently."
