The thought never occurred to me: scratch-building your own turntable. Paulo Rebordao writes:
This is a record player complete with a servo controlled arm that I’ve designed and built during the last 10 months. It has a few unusual features and I think it looks Way Cool!!!
Besides some general info on the workings, I also made available the schematics and software for downloading.

Record, that is a SteamPunk thing? ;-}
That’s what we old timers used before compact disks. It relied not on the optical properties of a laser to read pits in a reflective surface, but instead measured the “valleys” and “mountains” encoded on a disk by scraping a probe over the surface with a diamond tipped probe.
Les Paul (yes, the same Les Paul who made all those guitars) built his own turntable back in the 1940’s using a flywheel from a Cadillac engine driven by an electrical motor salvaged from a dental drill.
I think that using a gear belt to drive the platter is a bad idea. Each time a tooth engages or disengages it will modulate the motion of the platter. Stepper motors are not ideal for the same reason- use a servomotor.
