Eumig S 810 D advice

[Gary Roberts]

I am new to the group and little knowledge of equipment management .

my dad was a big 8mm fan but sadly died almost 30 years ago. We have loads of his films and a couple of projectors , one of which is the S 18-0 D . It’s mums 90th birthday next month and I wanted to show a few of the films at a party but find that longer films (larger reels ) tend to jump whilst small reels are ok. Looking for advice please

Greetings from Essex innit.
First off just love York.
My guess would be that the big reels have splices and the jumps are on the splices.
I assume you know how to load the film with the looper held down. Do the jumps correct when you flick the looper?
Are the films Std or Super? The later seems less tolerant of iffy ageing splices.

Hi David ,

Thank you for your response and kind support. My mum lives near Chester , both lovely cities .

They are Super 8. I have used projectors but not as competent or knowledgeable as my dad was.

There are instructions and I held the loop down until loaded. The small reels don’t jump but a larger reel does. I did try to correct by pushing the loop down but to no avail. I note the projector is self lubricating , it did take a while to get going and suspect that whatever it lubricates is struggling

Still haven't been to Chester Zoo.
Worth trying, take the back off and you will see two circular clutch plates and a brass drive on the motor.
With the power disconnected put the projector into play and the brass drive will contact the plate. Clean that plate with meths and wipe the brass drive too.
It maybe just losing friction. If the plate is shiny you could try some fine abrasive cloth to dress the surface but it could be in need of a service. My man is in Stanmore just near the end of the M1 and a few miles off the A1.
See how you go.

Thank you once again, will give that a try

Time is not with me to get it serviced and I am struggling to find anyone near me .
Dad used to go to a place in the midlands to bud on films and buy equipment, went with him a couple of times . My favourite film that he had is Titfield thunderbolt , although a short version

I agree with David, it sounds like bad splices. There should be no difference regarding reel size. The only difference is that a 50' reel has no splices and a larger reel can have many of them. There is nothing at all on a Eumig 800 series machine that can be affected by the length of a film because those machines are fully sprocketed. You may however want to check that neither sprockets can be turned by hand while the machine is not running. If either do then this can cause the problem you mentioned. In my experience it's almost always the upper sprocket that is cracked and loose. If you can turn it all by hand it is probably cracked and will need epoxy on its shaft....a very common problem with the 800 series machines.

I agree with Joseph's comments, and advice! He knows what he's talking about, and has a lot of knowledge with Eumig projectors. He helped me get two of mine up and running, and they are performing like new machines! These aren't hard to work on, but there are some things you must know before you tear into one. I would advise you to clean the rubber discs well with alcohol, then follow-up with a few applications of rubber restore or renew. This will give better traction against the motor assembly. Sometimes the plastic motor mounts are bad, and need replaced. I did this on both my Eumig Mark S 709, and Mark S Super 8 projectors. Good luck I hope you get those jumpy films figured out. My money is on splices that need to be redone. You may also want to lubricate the films. They may be dried out and this can cause unstable images. Filmguard is a good choice.

Thanks everyone for your support . Seems the issue is sorted as I found the small sprocket was not pushed back far enough . I took the back off but couldn’t see what I needed to clean but having replaced it there is now no sound
on the plus side , I have retrieved my S931 and despite it having not been used for about 25 years works perfectly .
any ideas regarding the sound ? How do I get the 810 D serviced ? Or is it worth it?

Forgot to mention . The TRIC light is on

Hi Gary,

Is there any hum from the speaker when you turn the volume up?

As you have removed the back, check that the speaker is still connected. This could be wired or bent contacts. If the latter, it’s worth cleaning and slightly bending these contacts to ensure a good connection.

If you have hum but no sound, without film in the projector, repeatedly press the red record key at the back.
It’s also worth switching the N/S sound selection switch behind the removable front panel.

The speaker socket at the back can also cause sound loss. Worth spraying contact cleaner into the socket.

Does the TRIC light meanit is in record mode?

No humming (there was before), I have tried bending the contacts without success. What would you suggest as contact cleaner?

I have been using this one…

If you have an external speaker repeatedly plugging and unplugging the two pin din plug might help to clear any oxidation.
