Simon is correct here. It is not so much that the disc drive is the problem but rather the mountings of the motor which deteriorate over time and affect the precision of the contact between the spinning rubber disc and the metal drive wheel. I have encountered this problem quite a few times over the years and when the mountings are replaced the problem is solved. It is possible to make your own replacement mountings with resin and so long as the original mounts are not too badly deteriorated you can use them as proformers to make replacements. It means removing the motor, which is not so much a problem, but the internal (rearmost mount) can be fiddly to remove and replace, but not impossible by any means. well worth doing because they are a great machine and so well engineered.

Hello, Terry and everyone

One can say that the Eumig Mark S projector is well engineered. Four bores in the roof leading to the main shaft bearings plus felt lines would complete the refurbishment.
