I like this arrangement: it's simple and common-sense.
It looks like your cork is missing some pieces.
-but even before I fixed that, I'd put a socket on that hex-nut and turn it gradually tighter while testing the effect on the spindle's torque, you know: for Science!
(Not too tight, though! this one needs some slippage.)

Very nice looking projector Dave. I love it's simplicity. Have you compared the rewind ASSY to the ST 1200? There is a service manual for the ST1200. As Steve has suggested perhaps they are close enough to have the same or similar adjustments... Although no guarantees.

Wow! That's late!
It's a shame I was poor and preoccupied in college in 1983: I would have loved to shoot some films with sound.

Yes,
The fork-thing is just for rewind. It does sound the clutch on your rear spindle needs some attention.
I'm not much help here because I've never had this problem, but if you search both versions of this forum (or Kevin comes on his thread), I'm sure you will get an answer.

If you loosen the screw and give it a little twist before re-tightening it, the drag on the rear spindle can be increased, just enough to make rewind work better.

Elmo ST100 takeup reel tension
I have an Elmo ST100 that appears to have very little tension (torque?) on the takeup reel. It’s (mostly) fine for playback, but upon rewinding it can get ahead of itself and start to dump film onto the table and also make for a very sloppy wind on the supply reel. Temporary fix is to use a finger to apply slight pressure on the takeup reel during rewinding to get an even wind on the supply reel. I’m guessing there’s a torque clutch that needs replacing or adjusting? BTW, all belts are brand new and have had no effect on this. I don’t have a photo right now, but it looks some sort of cork-like or old rubber material is dried out and cracked in the mechanism I’m describing as a torque clutch for the takeup reel. Is this easily fixed, or does it need professional care? I was actually going to bring this projector and my Bolex to a (rare) nearby repair shop for evaluation but I thought I’d ask here first.Tags: None
