I would like to build a very simple, circular wooden platform that rotates automatically - no stopping. The torque is not very important, as it doesn't need to support much weight. As far as rpm, not too fast, but not incredibly slow - about the pace of a fast escalator? That's the only comparison I can make. It's for an art project. I know this is probably an easy one for most people, but I am starting from square one. Thanks for any help.

\$\begingroup\$ oh yeah and the platform is about 2-3 feet diameter \$\endgroup\$– Peter BarnettCommented Oct 18, 2012 at 19:49

\$\begingroup\$ Where is the electronics problem? This sounds like a mechanical problem, which is off topic here. \$\endgroup\$– Olin LathropCommented Oct 18, 2012 at 19:56

Why not just buy a record turntable? Stick a 3 foot platform on it. It's kind of fast, and doesn't support much weight.
Or get a small motor off eBay, and make your own.
You just need some bearings to hold the turntable, and a belt to connect the small wheel on the motor to the big wheel on the turntable.

1\$\begingroup\$ There was some electronic content in that question, which I answered. Also note that nobody is trying to close that question, whereas this one got closed quickly. \$\endgroup\$ Commented Oct 18, 2012 at 21:43
