Bulk Loading 1000 foot load of 5222

[Donald Qualls]

I guess the cameraman can reloaded in a shaded area?

A 100 foot spool of 35 mm was for amateur cameras, almost all of which switched to 16 mm when it became available (much cheaper), and then 8 mm when film was good enough to support such a small frame, at least on a small screen.

Perhaps the Hollywood pros use small 100 foot spools in "crash cams" that they use to film car crashes and things like that that typically run only a few seconds.

Maybe. The modified Nikon SLR that was used to shoot frame by frame for the animated mine car sequence in Indiana Jones and the Temple of Doom had a smaller magazine, something like fifty feet IIRC (which was already an available part for Nikon at the time).

The daylight loading capability is/was generally unneeded for professional cinematography, though; they had the resources to handle loading magazines (which avoids having to cut off two or three wraps of edge fogged film from a daylight spool). These were still fairly common in 16 mm when I was a kid in the 1960s and 1970s (especially because Double 8 used the same film width and in some cameras the same spools) -- and 100 feet of 8 mm, doubled over, was a bunch.

Why would they use 100 foot spools? That's only a little over a minute at 24 FPS. 400 foot is good for 4 min 26 sec and 1000 foot is good for 11 min 6 sec.

The cameraman typically doesn't load film--that's the job of 2nd assistant camera, who is also known as a clapper/loader. They load/unload film spools into the film magazines in big changing bags (although bigger sets sometimes have portable darkrooms).

Don't do Cinema so going by what I heard from a Hollywood Cinephotographer . So I stand corrected.

Anyway, the black Kodak Spools I use came with 35mm hundred foot rolls of bulk film intended by Kodak for still photography. These work just great for respooling my 5222 and 5231, which I have in 400 rolls.

Actually, the 100 foot spools of 35mm were designed for volume portrait studio and identification cameras that took 100 foot rolls, but were in more recent times re-purposed for amateur use.
And the equipment used for creating them is old and expensive to operate and inefficient - at least Eastman Kodak's equipment is.

Sounds like I should get good measurements on one and 3D print it. Done in three parts and glued up, I should still be able to get it to fit inside a 100' loader.

Well they were used by both.

The B&H Eyemo 35mm camera came out in 1925, ostensibly as an amateur camera, but were quickly pressed into service by Hollywood for special shot use in aerial stunts, crash cams and other specialty shots.

1 minute of screen time is more useful than most imagine, especially in rapid paced action sequences.

But the 100 foot daylight loads were used for many applications such as Matt outlined, so I am unsure which came first...

I remember as a kid that some banks had a system that used 16 or 35mm for recording checks you deposited; you endorsed the back and then the teller placed it on a copy-stand like contraption that had two lenses. One of the lenses took an exposure of the check and one was oriented toward the customer and photographed them as well on what I assume was the same frame of film.

I have a 1000 split reel that I transfer the bulk film to then use a 16mm film rewinder clamped to the bench either onto a 100' reel (microfilm) or core. This can be done flat or upright, but with 1000 feet i recommend upright to eliminate friction from the weight of the film.

The first thing you should do is a clip test to see if the film is even any good. "Bought at a swap meet" usually means it has been exposed by some curious person. Or it might be old/cooked in an attic. Never know. Open the can in complete darkness of course, clip off a foot or two, then load and develop it like normal. If the film isn't fogged, then it should be worth your effort.

I like Saganich's setup. Mine isn't as sophisticated.

I spool down 400' rolls onto 100' bulk film spools I've saved over the years. The ones with sides work best but I haven't seen those in years now. Most bulk film comes on cores now. Shame. I use a film winder I think they are called (or maybe rewinders?). Two are attached to a 1x2 then clamped to the counter. My winders are for 16mm but I just put a clip on the end of the post to hold the spools on and it works well. Only takes a minute or so to fill the entire 100' spool. Then I put them in their cans and voila. It goes real fast. You can find the film winders for pretty cheap if you look around. If you respool the film manually you will be questioning your life by the time you get one 100' spool done. Takes forever. Better to use the Tom A method at that point.

This might be a good application for a set of IR goggles.

the 100ft 35mm spools are sometimes known as "Eyemo Spools" #10 Spools, and a few other names....

Microfilm in General used film on spools. Microfilm spools are generally plastic while movie spools are generaly metal. the microfilm spools have extra drive holes for some cameras. getting hard to find.

the Kodak bulk film that came on a spool was the #417 roll.

Here's a few shots of film-on-core measuring sticks we have around the lab to help with measurements. One is predicated on 2 and 3 inch cores and the other has a scale for 3 and 4 inch cores.

wow, those are neat!

Honeywell Nikor had a Film Processing Machine that would allow the loading of up to 100 feet of 35mm film onto stainless steel reels up to 17" in diameter. You would have to reverse the loading direction.

Yeah, they are handy for quick estimates!

Thought it might be helpful to answer the questions about diameter of film rolls. You can make your own based on these photos; should be close enough for Government work...
