Hi,
Does the Eumig S 810 D Lux sound projector for all 8mm gauges have a way of adjusting the speed?
I just got it yesterday and it hardly moved so I gave the cogs etc a grease and now its going almost as it should.
I think it is running a bit slow.
I've looked in the back and found what looks like a speed pot,there's only one though.
Any advice?
Cheers,Clinton [Smile]

Clinton...You can adjust the speed with the front 18 - 24 switch by placing the switch at a position somewhere in between the 18 - 24. If it's not running at 24fps perhaps the motor needs some oiling. I know those pots you are referring to... but I don't recall anyone mentioning there was a way to internally adjust the speed. Hopefully some other Eumig experts can chime in here [Smile]

Thanks for the reply Janice,I had to grease the cogs etc to start with as it hardly moved in forward and slowed to a stop in reverse,that got it running as it should apart from the speed.Let's see what other thoughts are given and hopefully I can get it going right.It is Standard and Super sound which will give me a backup projector if my Elmo dies!

The manual says : "Important : Before changing the running speed, always turn the main switch to stop and connect the projector to the main supply. After switching from 24 to 18 fps, wait for a couple of minutes before projection to slow the flywheel speed to stabilise." Will probably not solve your problem but good to remind.

As these models get older and older it is important to give the motor a good run in the non-operating position to get it well warmed up before lacing a film.

Hello, Clinton. Please tell me: in NZ do you have 50 or 60 Hz mains? And where did your Eumig come from?

In the meantime, it is advisable not to lubricate ANYTHING at all more than you have rightly done yet: the motor does not need anything like that if it runs very siklently while in stand-by mode. Instead you should check that the pulley on top of the motor's shaft is clean and not slippery. Also the rubber covered discs might be hardened and/or somewhat dirty or greasy; in either cases this will cause the pulley to slip to a certain degree when transferring power to the mechanism hence (one) of the possible reasons for your Eumig to run a bit slow. And no, to the best of my knowledge there is no electronic regulation (trim pot etcc) to fine tune its speed: it's a totally mechanic contraption relying on manufacturing precision: both the discs and the pulley are slightly wedge-shaped and this lets the projector achieve the speed change. So both discs and pulley must be clean. If not use a cotton swab with some isopropyl alcohol. If the rubber is hardened, use the finest sand paper and rejuvenate their surfaces just a little so proper contact and grip between pulley and discs is restored. Also check the mains frequency: if the machines is set to work at 60Hz but you have 50 in your area, the projector wil lnoticeably run slower than due.

Speed potentiometer's are only ever necessary to trim the speed on D.C. motors not A.C. ones like are fitted to this machine.
As Maurizio points out, speed is mechanically governed on this type of machine, not electronically.
Maurizio, as always, offers some good advice here.

The electricity supply in New Zealand is 230volts @ 50Hz.

Mauricio is correct. Do not lubricate anything. There is no speed adjustment other than the 18/24 fps switch. The problem is the contact between the spinning disc on the motor shaft, which is critical. The circular plate that the spinning disc makes contact with is usually rubber coated, although I have seen older models that are plain aluminium. The spinning disc has an outer rubber ring which makes contact with the circular drive plate when the projector is switched to forward or reverse. This simply rocks the motor from a central neutral position to the drive position which brings the spinning disc into contact. The rubber on the spinning disc can be the problem, because unless it makes contact at the correct pressure, the speed of the projector will be slow. Try cleaning both the circular drive plate and the rubber on the spinning disc, this sometimes works. If not take a look at the motor mountings. They are prone to breaking up, in which case you may have to replace them with home made resin or rubber alternatives. Again these motor mounts will affect the critical contact of the spinning disc. It may sound daunting but I have undertaken it successfully.

Good to know about the motor guys. I'm making a note of this [Smile] When I've had issues with my Elmo's... the advice has always been to drop some oil on the bushings. I guess that's not the tactic with the Eumig. I also have this same model Eumig and did all the things you have suggested when I first got the projector. My machine is still running fine, so hopefully these steps will improve the performance of Clinton's projector also.

Rather than sanding the rubber disks, try using ordinary brake fluid (glycol-ether not mineral) left overnight. This causes the rubber to expand.

Here is a picture of the screw behind the 18 - 24 lever (centre of pic).
I noticed mine didn't go all the way to the top so I undid the screw and moved the back plate slightly,and it worked.
Thanks to this wonderful forum as always!

In response to Tom's post, I removed the motor on a scrap Eumig Mark 8 a while back pretty easily. There was a small spring on the reverse which came off and I couldn't make out where it fitted. Replacing the motor mounts looked to be straightforward but it could be a pig to put it back together. Glad you sorted your speed problem, Clinton. The lever operates a collar, from what I remember, which raises the motor drive to a different area of the disk drive to increase the speed. I guess that the rubber disk had worn at the original setting.

Great.
I've never seen a Eumig 810 with yellow/beige handle and other parts.

Maurice, i think you'll find thats what the years do to the white coating,(a bit like very early plastic windows, they go a wee bit yellowy) [Big Grin]

Hi Paul, that is a great YouTube video,my problem fixed now,I let the projector run for a few hours and everything seems good now.
I liked the way it actually showed the pads etc people talked about!

Tom,
years ago I replaced the motor mounts on a mk s using the parts supplied by John White.
it was quite easy except for the fine adjustment,ie exact position of motor in relation to its mounting.
I never got my mk s to run properly in reverse but managed to get it going ok for normal forward projection.
