I have a Revere 85 regular 8mm projector that's been in the family for 60+ years. The fiber gear on it stripped. Anyone have a good one they'd be willing to sell? It's one of the key drive gears inside and one of the few that's not brass/metal. I guess it was made to self-destruct after 65 years. Well, it did. If you need a picture, let me know.

Hi Ken. There is a Revere 85 8mm projector listed on the Minneapolis Craigslist. It's been listed for 11 days already. He is asking 50.00 or offers. He will not get 50 for it so maybe you can offer him 15 or so and he will bite. If you are intent on keeping the family projector for sentimental reasons, you can swap out the gear, otherwise, just use it instead. I've sold a couple of that model on Craigslist and I think it was for 15 or 20 bucks. I'm in Burnsville.

Thanks, Barry. I've picked up one via eBay that should work. Why did they build them with a fiber gear? I suppose to "blow out" before other components got wrecked.

That's a possibility, but there was a lot of experimentation done in those years. Bakelite, nylon and brass gears were all being used.

This one's either bakelite or nylon, I'd guess the latter, but I'm not sure. It's dark and kind of fibrous. After 66+ years of use off and on, and hardly any for the past half dozen it just decided to strip about 1/3 of the teeth. End of film drive! Do you know how that gear comes off? I've taken the projector apart to the point that I can see the gears etc. but I'm not sure how to detach it from the "gear-box" if I do decide to repace it. I'll probably just go with the other one and save myself the hassle.

That's the problem with what we do and when we are doing it.

-If the salesman had told the original buyer that the gears would last 66 years it would have sounded spectacular!

("By then people will drive atomic rocket cars and live on the moon!")

-yet here we are 66 years later...

You should look at websites like McMaster Carr, with a little luck maybe your gear is a standard size and there is a modern replacement available. (No harm in trying.)

I'm not familiar enough with the internals of that projector to be able to say how the gear comes off. If there are no retainers visible, it may have been pressed on.
