At 8:51 at he bottom of the page he quotes a motor speed of 8000rpm (ish).

The recordings of it working would sound way more impressive if it was spinning that fast.

Also the quoted speed I don't think is a harmonic of 50Hz AKA 3000rpm.. And since at least one disc is being spun by an AC synchronous motor it needs to be... I'm no expert on synchronous motors, I only have a faint understanding so I could be correctable there.

I do have it on good authority that "ours wobble" (at least our early ones did) so it does have that going for it!
