This Eumig 510D projector is starting to do my head in ... I'm either going to put it away for a while or bin it!
The hub wheels are not doing as they should.
The top full reel isn't constant so it loosens and then jolts the film causing the onscreen pic to jump.
And the bottom takeup reel is a hit and a miss!
The video shows the situation,adjusting the tension on the ends inside the projector haven't make it right.
Help please

What have you already checked Clinton? Have you removed the supply reel arm casing to see if there are loose belts?Gears that might need lubricating? On the take-up reel...What kind of gear assembly is it? If it's friction...has some oil gotten on it?

The video was very short and didn't show the upper movements of the reel assemblies...but everything else seemed to be running ok. It didn't look or sound like the motor was stalling.

Hi Janice,
I don't think it's the motor stalling either.
I took some screws off the back of the top arm as I wanted to see how it worked etc.But it looks like a bit more pulling apart is needed just to have a look.
I will step back for a few days then have another look and remove more to get to it [Smile]

Take a look at this video. It's not a Eumig projector...but the symptom is similar. This is why I suggested you look at inside the arms to see if something there could be the cause.

Report back what you find.

Thanks for helping me with this Janice [Smile]

Yes that looks exactly the same problem.
I've found that sometimes you have to stop working on it for a day or a week and then go back,like I did with a Tacnon sound super 8mm projector,I got frustrated with the belts and how to replace them etc and eventually it just "made sense" and taa daa .... a working projector.
This Eumig looks like it doesn't have top and bottom sprocket wheels,the film basically goes to the filmgate,and hence the jolt causes the picture to jump!
I will go back and think about it soon and report my findings or my frustrations [Smile]

You seldom get entirely smooth action from the feed spool if you have no top sprocket, let alone one without a bottom one also??

In fact, aside from an early toy projector I once had, I don't recall seeing a projector without either bottom or top sprockets, I have to say.

Ones without a top, tend not to like running full reels of film at the machines designed top end capacity as they age.
They invariably use some kind of flexible plastic arrangement to form or assist the flow of the film into the top loop and subsequent gate.
This is never anything like smooth in action though in my experiences, especially if the plastic has aged badly and lost any of its initial spring or now contains too much flexibility through usage over the years.

First try it by avoiding placing any heavy spools onto it and by using very small amounts of Film with it to begin with.
Say 200ft plastic reels with film on maximum to begin with,and see how it fairs at that point first.

From your short video clip, one of your belts apparently driving through to the take up spindle, appears very sloppy also. This will surely not help proceedings.

The Eumig 501 also was sprocketless and also gave a worse steadiness at the ends of reels. The 900 series members without top sprockets were bad enough.

I would think it was essential for the rewind through the gate for there to be no sprockets. I wouldn't like to have to design sprockets and drive that would move out of the way to allow that.

The Wizards from Vienna eh? [Big Grin]

Agfa managed it Brian or rather the parent company manufacturing these. They did it with ease and excellence on the LS models with one lower sprocket wheel.

I do the same thing Clinton...sometimes putting the projector back on the shelf and getting back to it months later. I'm usually in a much better head-space then and able to determine if the repair is worth it.

That's a good rule for life in general: I've banged my head on problems at work for hours and come up with diddly...

-get up, take a walk, and have a solution in less than ten minutes!

(-maybe that's why they assigned me a bike!)

If you can't get it sorted, Clinton, as it weighs over 17 pounds, it could be useful as a doorstop, something to hold stuff down on DIY projects or to build up your arm muscles. The drive belt fits the 501 and 502 models by the way. I have a couple of scrap projectors which I thought would make nice ornaments around the house but my proposal didn't go down well with my better half.

Do I have to take off this hub holder that has the coggs etc at the top of the picture to make it easier to get into the back of the actual arm where the belts are? And here's a better video,the cogs are turning as they should so therefore it must be in the arm?

Looking at my scrap 510, as far as I can see, the only way to open up the feed arm would be to remove the hub holder as you suggest but good luck putting it all back together again.The take up reel, though, has the same problem but that's a direct drive to the hub. The disks with the milled edges on the end of the hub shafts are used to adjust the tension by increasing/ reducing the pressure on springs. I think you said you'd that tried that adjustment but it made no difference.
