Since there's no activity over here, I may as well direct you to an interesting project involving a stripped-down Lenco idler drive and platter, being coupled via an idler wheel to a second, passive platter on which records are played.
The only physical connection between the two platters are via the idler wheel, and the long-way-round via the shelves on which the mechanisms are mounted, and the wall on which the shelves are mounted.
Go over to Lenco Heaven (maybe that's where everyone has gone, anyway) and take a look:
