Back in 1968/6th grade I was the nerdy kid who helped out our less-than-technical teacher. I grew to be familiar with those projectors. The trackway behind the lens needs to be very clean. There should be a loop of film above it just before it enters (you can see it on the projector) to buffer the jerks and help ensure a straight in approach. Oh, and the really big reels never worked well. Too heavy, even when those projectors were new. We often had to help them along by hand the whole time. I know we had them at least when I was in 4th grade. Lots of good educational films from AT&T and Bell Labs. Weather, phone systems, health (smoking, alcohol), can't remember what else. Thanks for the memories!

Ha - I was that kid 10 years later! I'll bet you had the previous generation of Bell and Howell projectors that were built into the case and had much more nicely machined parts and film spool holders that you had to take out of the projector and stick in holes on the top and sides. There were a few of those left in the 70s - I wish I had one - but most were like the one in the video. We were overseas a lot so a film was an extra special treat since TV was nothing like at home if available at all. And today most kids wouldn't understand the joy of watching a movie in class now that a million videos are available at their fingertips. Glad it brought back some memories!

Hi Thanks for the video I still have one of these Bell & Howell 16mm projectors. But haven’t used it for years.

Glad you enjoyed the video! Sadly, as a number of commenters have pointed out, some of the plastic gears in those Bell and Howell projectors deteriorate and crack over time. Cracks are visible in some shots of the projector in this video. So if you do have issues whenever (if ever) you use the projector again, the good news is that replacement parts are being produced by various individuals and are available online at times.

Great stuff.I could spend a whole Sat afternoon with you tinkering with those old projectors.I was VERY into Super8 for many years,but always dreamed of having a 16 mm.Mainly because of the much better picture quality.Many memories from school regarding these 16mm projectors.One of my fondest memories was 11th grade(1982 for me),when the last few days of school,our science teacher would bring in prints of Star Trek.I sat in awe of the big ,clear picture.It looked so much better than watching it on tv. But for sure,that projector needs alot of work.

They are really neat technology. I wish I had one of the previous generation B+H before auto threading. They were really well built - all metal construction and no plastic work gears to deteriorate over time. Print of star trek - wow - must have been fabulous to watch those. What lot of people dont appreciate was how back then standard definition TV was way poorer in quality than what it is today with digital signal processing. From the time period you mentioned we must be almost the same age and had the same TV and film experiences. Its funny - I have also dreamed of having a 16mm camera. Maybe one of these days - I was looking into it a few months ago and while film+ developing is crazy expensive these days, 16mm seems to be only a bit more expensive than super 8, so thats really the way to go these days. Thanks for comment - always great to hear from someone who know the old analog technology!

Interesting. Just take out the sound bulb and shine a strong flashlight into the photo cell to restore the sound.

@@joshhoman I think it has more than half a chance! Looking at the size of the original bulb and how its housed (ie no much opportunity for heat to escape) I would guess its about as powerful a vintage Christmas light bulb - maybe 5 watts. I sure a modern LED flashlight would do it. Sometime I will have to get the old projector out and try it and make a video .....

24 volts, 250 watts definitely seems like an odd ball rating, maybe that's common to all projector bulbs. Another rating I common see in office depot and staples, is 82 volt 360 watt, for use in overhead projectors, the kind with the transparent film where the teacher would write on with erasable markers. I remember those being used throughout the 90s and well into the 2000s. I went to a two year trade school for industrial electronics from 2013 -2015, and they still had a few in use, though by that time most of it was digital and used the LCD projectors with HDMI inputs, wifi connectivity what have you. Speaking of the compact filament size, many modern projectors use metal halide lamps or, in the case of very large projectors used in theaters and drive in movies, xenon short arc lamps, which consume several thousands of watts and often requires water cooling, the brightness is comparable to a welding arc.

24V was common in 16mm projectors 50 years ago. I think partly because the film frame was so small you wanted as small a source of light as possible. I guess I didn't mention it - the bulb for this project was halogen, used there before they became common for household lighting. I never heard of a 82 volt 360 watt bulb - thats is an odd voltage. Was there a power transformer in those projectors? Or did they use some sort of triac based dimmer type arrangement to keep the weight and cost down? I have never seen a xenon bulb in real life other than photo flash units which of course are only operated for 1/1000 of a second at a time. I remember reading how early Imax projectors used a xenon bulb type that was used by the US Navy to burn barnacles off the sides of ships and submarines in dry dock. Apparently they had to jump through a number hoops to get permission to use it for civilian uses. It also cracked the condenser lens the first time they tried it. Did you get to work with any of the larger movie projectors you mentioned in the industrial electronics program you were in or elsewhere? I always though they would be interesting to take a close look at!

@@ElectromagneticVideos not sure about how the 82V bulbs were powered. If I had to guess, it was probably a resistor, or maybe an autotransformer, I have never worked on those particular overhead projectors, but the 82V 360W seems to be pretty common here in the U.S.A anyway, for overhead projectors. My uncle Chuckie worked in a theater while he was in high school in the late 40s /early 50s. The old theater had been demolished about 15 yrs ago, around 2007 or '08 after having been abandoned since the late 1960s. Anyway when he worked there it was used as an Oprah house, and he worked with carbon arc fellow spots, and salt water dimmers, as well as resistance dimmers aka rehostats, and autotransformer dimmers aka variacs. A salt water dimmer was a container of salt water with two electrodes, one fixed and one movable. Moving them closer decreased the resistance and made the lights brighter, and vice versa. He also used to call them piss pots, for two reasons. One being the ammonia like odor as the salt water boiled away from the large currents flowing. Second reason, legend has it that operators and projectonists would sometimes replenish the salt water by urinating in the container. If that's true, hopefully it was done with the power off😵

@@Sparky-ww5re Salt water dimmers - that a new one for me! But it did suddenly remind me of a humidifier we had when I was a kid. It had two electrodes that dipped into the water and heated it up from the current between then. My guess is salt was put in the water. I'll bet that salt water dimmers or humidifiers would not be close to passing any safety regulations these days - and thats a good thing. At least the dimmer was in a "professional" environment. I wonder how many humidifiers were knocked over (and the containers was breakable glass) with salt water and energized electrodes landing on the floor and zapping people. I'm sure the only thing worse than electricity + water is electricity + salt water! I do wonder about the urinating story - I would think the resulting smell would be a deterrent to doing that more than once! Working with carbon arcs must have been interesting - I'll bet a lot of delicate adjustments as the carbon rods gradually got shorter.

I have another old one that actually was from the military and is more of camouflage green than this one. I'm guessing that since the military was a major purchaser of projectors and had a specific color requirement, the easiest thing for the manufacturers to do was to simply make them all them all a color that was acceptable to the military since other customers really weren't too concerned about the color.

Question- does your bell and howell 2585 projector get hot. Mine tends to get very warm to the touch. Is that normal? Thanks

Cracks are visible on that worm gear.

Bell & Howell 16mm Filmosound projectors exist in two states. 1. they either don't work because the plastic worm gear has failed, or 2. they are about to fail because the plastic work gear is about to disintegrate. In your movie, at around 18:12, you can see the cracks in the worm gear. They are ALL like that. The worm gears on these fail due to age (and not because of use). They are now all about 40-50 years old, and basically junk unless the gear is replaced. There were better projectors coming out of Japan such as the Eiki machines. Obviously, the Swiss Bolex machines were many times better, and will last forever.
