Last nbight I ran into a major problem with my Chinon, but I may be able to fix it.

The story is as follows.

I was going to screen my brand new never screened print of "Something Short of Paradise (optical feature), and the leader that i had attached had the label on it, but it had a "bump" on the label, (where it didn't stick together right).

Without thinking I started to thread the film, and it wouldn't go through, even with some coaxing. So, I took that portion of the leader with the bale and cut it off.

Now, when I loaded it, the picture, while going through, was quite jittery and kept on loosing the image, (just becoming a blur, as the claws teeth were not connecting with the film.)

This had happened to me with a Eumig optical sound projector before, but I never figured it out.

Thankfully, I kept myself from drop kicking the projector across the room, (I did that once and strangely enough, that projector never worked again), and fumed as to why this would happen with a brand new projector! (it is new, out of box).

I took a flashlight up close and examined it. Sure enough the claw and teeth are just fine and not only that, going in and out as they should. So I was stumped.

Then a car analogy occurred to me. It's all about "timing of the engine".

I'll explain.

I'm wondering if, by trying to get that "bump" to slide through the projector, I may have altered the "timing" of that first wheel (where the film feeds in) by just enough so that it doesn't make the sprocket holes of the film, line up with the claw and teeth, and since they don't line up, the teeth can't "shutter" the film through image by image, thereby giving us the movement we know and love.

My theory (and possibly fact) is that the first wheel, (up there where the film feeds in, is crucial, for it must bring the sprocket holes at the right timing so that they can shutter that image one at a time.

Therefore, the analogy of the timing of the engine!

I'm going to test my theory tonight, as I'm really flustered by : One, my stupidity up attempting to get the film to go through and not knowing just how delicate that "timing" is.

Having still many other optical sound prints that I haven't even watched!

What do you lads and lassies think?!

Your story reminds of the time I was running a brand new film through my Eumig 802, and as the tail end of the film went through the projector there was a loud metallic noise. I found out that this brand new film had a metal staple punched into the tail end of the film! [Eek!]

Hey Paul, that story sounds hauntingly familiar! Was it a certian print that you bought from someone if I remember correctly.

More importantly, did you remove the staple. (now there'e a stupid question, eh?

and ... just who, in the "right mind" (that may say it all) would splice a film with a BLOODY STAPLE!!! ???

I was fiddling with it last night but didn't get anywhere with it. When I had watched that first reel of "Something Short of Paradise", wqithin a few minutes of the first reel, it starts to jitter a lot, then loose the loop, so to speak, or , as I think the problem is, the out wheels and claw arm are out of sync.

Any advise on that? It's really a bummer as I just recieved my Optical print of "Pale Rider" (magnioficent L.P.P. color on this!) and I can't watch the bloody thing.

Does anybody have any advice on this Chinon 9500? I know at least a few people have them, on the forum.
