Eumig 501 running slow?

Post by Westinghouse »

Hi all
Firstly - let me introduce myself as I've only just joined this forum. My names matt and I am a complete amateur with 8mm! I've picked up a few standard and super 8 films and the bell and howell projector I got is very fiddly to load so I got one of those eumig 501 machines as I read that they're pretty good.
Thanks to Hermes delivering, I had to buy a new bulb and have today successfully fitted it and gotten films running.

Anyway - when I run films (at the full speed according to the dial - not the slow option!) they don't seem to run at a normal speed and the footage seems to be slowed down slightly - I've tried several reels and they're all slightly the wrong speed.

Does anyone know what I need to do to rectify this problem? If people could use picture and laymans terms as I really am new to all this - that would be ace.

Many thanks in advance.

(P.S. Sorry if this has been answered elsewhere - I'm currently on a mobile and so browsing / searching the forum is very tricky!)

Hi Matt, I don't know the eumig 501 but I'll try to help. All projectors I've seen that have 2 or more speeds like that will either have a belt that shifts between pulleys or they do it electronically like a modern lathe does. If it does it with pulleys maybe the pulley is loose? Does it also run too slow for 9 frames per second? If it does it electronically there should be a circuit board inside with 2 adjusting screws, one for the 9fps and one for the 18. Just out of curiousity, which bell and howell did you have that you think this Eumig is better than?

Do you have a mauual ? , This you can find online if you don't , best to read/ will show you where to clean and check the belt .

Hi Slashmaster - thank you for the information. I shall have a look inside and see if I can see any sort of belt or anything that looks loose!
As the 9fps is a 'slow motion' option - its hard to tell if this is slower than it should be. How does one tell?

The Bell and Howell I have is a Bell and Howell Model 625 Standard 8 Projector. Its a nice looking bit of kit but fiddly to load the film through and I'm pretty sure it could do with new drive belts (the coiled wire type drive belts - one has been bent or stretched and it doesn't 're-reel' the film very well - so if you're not attentive, it very easily stops turning and spills film all over the floor!)

I don't have a manual - I did try looking for one but so far I seem to only be able to find them in german.

Many thanks to all for advice.

I had the same with my Beaulieu Projector, Only in German or french , Takes some time seaching , but is out there , A Manual is a must , To understanding how and what not to do .

I don't know how the 501 drive works, but the Mk Series have a friction drive "gearbox" by moving the driving wheel to a different radial point on the driven wheel. There are two of the driven wheels as the motor is tilted to one or the other for forward or reverse. If you have this type of drive system, you will see that the speed changer moves the drive wheel up and down the motor shaft. There is probably an adjustment for it to get the speed right. There is also a positioner for 50Hz/60Hz.

There's a picture of this mechanism for the Mk8 on my website http://www.cine2digits.co.uk, click on the Film Transport link and in the second picture down you will see the drive system in the top right-hand corner. In the first picture you can see the speed selector control and if your 501 looks similar then there's a chance it has the same mechanism.
Off all the things I've lost, I miss my mind the most.

Eumig 501 doesn't run at 24 fps, its top speed is 18 fps.
So, if the film shot at 24 fps, it will look like slow motion on your projector.
Are your films in 24 fps?

The 625 is awesome! If the lens is clean you get a killer image! Only use a proper lens cleaning kit though. If I were you, I would run all my standard 8 films in only that! Is the spring only stretched in one area? If so I would splice that area out, or if it's evenly stretched splice a section out. I know all kinds of tricks to force more performance out of those so you can private message me if interested. As for how to tell what speed your other one runs, make a continuous loop of leader film. Use a sharpie or pen to put a mark on the film every 9 or 18 frames and you can tune it right on.

Fantastic - thank you for this - I will have a look when i get a chance!

I'm not entirely sure - they're purchased ones... I've tried one of them on another projector - a Bell and Howell filmsonic - and they're still running slow on 18 and 24 fps?

What a superb idea - i will give it a go when I get a chance. How does one go about splicing out the spring-drive-belt thing on a projector? Cheers!

Yeah, now that you have that Filmosonic, you're going to want a loop leader with the number of frames that are a multiple of 18 and 24. For example, 18 x 8 =144 and 24 x 6 =144. You can mark it one color every 18 frames and another color every 24.

As for the spring belt, never had to do one but shouldn't be hard, you can see the joint where it was made when new. I'll take a look at one for you when I get a chance. Probably possible to do with needle nose pliers.
