Dear friends,
a friend has kindly gifted me an ELMO ST-1200 projector. He bought it 40 years back and never got to use it, not once. I have a couple of 8mm films stored and I thought I could try and play them.
The projector is indeed shiny as new but four decades of disuse took their toll. The belts have been dissolved into tar and the lamp doesn't work eventhought it doesn't seem to be burned.
In addition, the 18-24 button (1) can't be pressed. That whole part that is supposed to move seems to be stuck.
I mean to give it a shot and try to resurrect this beauty and I thought I might get some useful ideas here, in your forum. On the net I found the service manual as well.
On ebay they sell belts but if I'm not mistaken, as long as there are capital controls going on here in Greece, I cannot pay via PayPal. I searched the net and I see there are local stores selling all kinds of belts but I need to know the sizes.
So, to make a start, can anyone tell me what the sizes of the belts are? (The upper one, with the cogs, seems to be ok).
And any ideas as to the stuck 18-24 button?
I'd appreciate any help.
Thanks in advance!

Thanks for the feedback, everyone.
@Dominique, not sure which part you mean with "lampholder". Here's a couple of pictures. As far as I can tell, there doesn't seem to be any visible rust.
@Andrew, I unscrewed the one screw that seems to hold the clutch mechanism but I couldn't get it off. Apparently, I'm not as handy as I thought. I'll have to retry it.
@Pasquale, I had gathered as much about alcohol as I had to clean my hands, the first time I touched the rotten belt. Indeed, I used alcohol to clean the wheels and now they're mostly ok.
@Thijs, thanks for the links. It's good to know there are all kinds of spares available, in case I need something. They are kind of pricey, though, and I had hoped to keep the budget low.
I think I'll print out the service manual and bring the machine to a technician.
As for the belts, I think I'll try and figure out which wheel is connected to which and use a piece of tow to find the length. Then I'll try my luck at local stores, in order to keep costs down. (I saved a piece and it's square, 3mm thick)

Dominique, only now did I realize that I could take off the lamp. And indeed, it seems you were right, there was rust, or rather salts, on the plugs. I've cleaned both the plugs and the lamp socket with vinegar and now the lamp works! That's one major problem solved. Next, I need to find drive belts.
Thanks a lot! ![[Big Grin]](biggrin.gif)

@Roger, not sure if you can still get a toothed belt. This one came with the machine and I'm sure it's the original one.
@Winbert, this machine has never been used before and all parts are the original ones. I understand, though, that there have been different variations of this particular machine on the market. See, for example, the picture I post below.
@Steve, indeed, there seem to be different variants of this very same model.

Further update:
Trying to figure out more about the drive belts so that I can use a tow to find the length, I came across this youtube video and noticed that my machine is different from the one there. The pulleys on mine (appart from a different placement) have one single notch when on that guy's machine they have two notches for two different belts. That explains, at last, why I have the feeling that I need less belts than ebay offers.
Anyway, I look at the service manual (which seems to illustrate the single notch variant) and I'm trying to figure out how the belt goes. Here below you see my suggestion on picture b, drawn with red.
Do you think that is correct?
Thanks
