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 Barnett Oct 18 '12 at 19:49

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.

Turntable

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.

    \$\begingroup\$ Unfortunately that teaches some unfortunate things. We close questions for a reason. Providing answers when you know the question will be closed partially defeats the purpose. \$\endgroup\$ – Olin Lathrop Oct 18 '12 at 20:28

    \$\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\$ – Olin Lathrop Oct 18 '12 at 21:43
