So no reactions to that video, eh?! Was it so offensive that nobody wanted to comment :-)

Sorry the lighting was poor.

Now I've added a squeaking sound that is pretty much constant. It sounds like something is not getting oiled properly...perhaps the vacuum 'roller'? I just put a newer vacuum pump on it recently, and it made the sound before and is still making the same sound, so I don't believe it's related to the pump.

Is there a mechanism that 'feeds' oil to the vacuum pump? Can it somehow *not* get oil? Or is that an impossibility given the way it's designed?

This video should reveal some light on the noise, although now it's turned into a full blown screeching noise:
