I'm working on a ST:TOS U.S.S. Constellation (battle damaged, of course), and plan to mount it on a Tamiya turntable. The idea is to show the ship slowly drifting in space. The problem is, the table rotates about twice as fast as I'd like it to. So my question is, has anybody here ever found a way to reduce the rate of rotation? Thanks.
Mark McG. It seemed like a good idea at the time...

I'm assuming it's a DC motor. If you can always add resistors in series to the positive side (trial and error) until you achieve the RPMs your looking for. You could akso add a potentiometer (similar to a volume control) and it would allow you to control the speed. Hope that helps.

Just make your own lazy Susan. You can get bearings from just about anywhere now. It's also easy enough to get a turntable type of device to put a bearing ring in/on? Any way - this would be easy to turn, and it wouldn't cost very much.

Maybe a picture of a squirrel playing a harmonica will make you feel better?
Thanks for the input, guys - I've never worked with a motor before, so any help is greatly appreciated.
RRA2,
Yes, it's a battery-powered unit; that's one of the charms of the thing, that it's compact and self-contained. A pot won't make the motor burn out, will it? I'm thinking of the dangers associated with running a home ceiling fan on a dimmer switch.
Mark,
The maximum a pot can feed the motor is only as high as what voltage you apply. In your case, it will be fine as you long as you don't exceeed the max voltage rating of the motor.
OH Boy! U.S.S. Constellation with turning; what more could one ask for?

this is what i'd do. half the voltage, half the speed.

You can try to find something like this on youtube, or try a VOLTAGE CONVERTER - to see what you need to do to get the correct voltage to keep your motor from burning up. https://www.youtube.com/watch?time_continue=6&v=HPhxSUlJRQI This should avoid some of the guesswork. I always use mechanical means whenever possible to avoid things like this. However, you can use whatever you feel comfortable with.
