So, are you suggesting the film is not tight at all?
It should be tight. From the pictures I see, I understand you located the possible culprit, yet:
1 - this part is called "gate" and not shutter,
2 - in your case, there is no apperent reason to assume the problem depends on it, in fact it looks like new with no signs of wear.
But you can do a very easy test to assess if you can absolve this part:
put a piece of film ( 4-5 cm, framed, white leader) in place and hold the gate against a light source: the film should offer some restraint in being let pulled but not too much; also the adjustable part of the gate should be set so as to have the frame line parallel to the film aperture AND the sprocket hole should be a little more than a hair off the aperture (OK let's say two hairs).
That's all I can suggest at this point, but also check to what extent the claw tooth protrudes into the gate: if it's too little, then wear of the claw arm peg has occurred and the tooth will never protrude outwards enough any more: it's time for replacement.
Good luck and let me know.

Hi Ilias,
As Maurizio said.......
"Look at the metal part: right around the film aperture, there two side guides, one fixed, one elastic"
Check that the film guide without the screws is free to slide freely on its track. I have seen quite a few of these that look Ok, but when tested they are stuck or tight, and wont slide freely. They provide the correct side pressure to the film. If they are tight or stuck then the film wont slide freely through the gate. Use a penetrating cleaning spray to dissolve any debrie behind the guide or in its track. Then try it again with your finger to ensure it slides freely under its spring pressure.
It uses a hairline spring which is very thin & must be spotlessly clean to work properly. Many are not cleaned properly for years & become tight, due to dirt, debris or wax deposited there by the film.
Also, check that there isn't a ball of fluff caught on the claw finger tip. This builds up slowly till there is a birds nest on the claw tip & it prevents the claw from penetrating the film sprocket hole sufficiently. Then it will start causing problems till its cleaned off.
let us know if that helps. ![[Razz]](tongue.gif)

Thanks for your replies guys,
i'm already looking for a new more reliable projector, but nevertheless I definetely want to repair this one.
@ Frank: thanks a lot for your films. The "elastic" part of the gate works ok, I've checked it and is moving without any hassle, in any case i've also cleaned it, as well as the rest of the moving parts, so no fluff either.
@ Alexander: I have been started to think that what are you saying is the problem. I've noticed that the film from the reel sometimes is not totally parallel to the reel when entering the projector, so a possible deformation not allowing the film to be released evenly sound possible to me.
I'll try looking for the parts, any chance anyone has any of the said part?

Hello Guys,
Today I am happy again!!!!!
PROBLEM SOLVED!!!! I still can't believe that the whole problem was created by the "fluff" around the claw. I couldn't even see that there was fluff aroung the claw.
So I took a toothbrush and some alcohol and cleaned it well, I've tested the projector with 3-4 reels that used to have problems and voila....the projector is working like a charm ![[Big Grin]](biggrin.gif)
I really want to thank Maurizio and Alexander, guys your help was very valuable and I really hope I can do something to help you in the future.
I have some more news though, I was at the local flea market yesterday and I picked up a real bargain. I got a eumig 810D for like very very cheap. I wasn't expecting it to work and I actually bought it thinking that I might be able to maybe use some parts.
I was more than lucky with that, came home opened the projector and it was impressively clean on the inside. Tested it with a crappy film and it was working like a charm. Even the lamp was working. Added bonus was the 1.3 eumig lens that came with the 810D, which is a great upgrade compared to my old 1.6 eumig lens.
This is the real dual unit, not like my frankenstein 802D.
The only problems with the 810D is
a) it misses the two wheels used for the normal 8mm (however it has the gates)
b) the plastic part with the silver metal that holds the reel on the bracket is broken or missing on both brackets. I checked the inside of the machine and it seemed almost impossible to change the complete bracket with all these sprockets that has inside, but I was hoping there is a way to change or fix the plastic.
I'll come back later, probably with a new thread and post some photos of the problem.

Hello again,
this is actually getting seriously on my nerves.
Last night, while thinking that the projector was fixed now, I tried to watch some films.
I watched 3 silent films without any problems, was very happy with the result, picture was steady and no tremling of the film.
Then I went to watch a sound super 8....
DISASTER....
when I turn up the volume, even if no film is loaded or playing I get a very loud humming drone sound.....The same happened with film.
I'm not sure if it means anything, but I remembered that when I was cleaning the projector to repair the previous problem I had accidentaly pressed a couple of times the red recording button on the back of the projector.
So, yesterday, after discovering the sound problem.....I was trying to figure out what was wrong and pressed the rec button again...and the humming sound stopped....
Any chance when I pressed the button while cleaning something went wrong and shortcircuited? I'll open today the projector to check the inside for any visible problems...
I am seriously starting to wanna throw the projector out of the window.....
