motor advice for rotating crt setup
bluevolume:
Any good sized 120v motor that includes the step-down gearing would probably work. I don't think a DC motor would be a good idea -- how would you power it? You'd need a pretty big transformer.
HarborFreight is a great resource for this type of thing, but make sure you wire everything up correctly and include appropriate fuses! HF stuff is a little "smoke and burn" biased.
DaOld Man:
If you use a 120 v motor, make sure it is reversible.

You're also going to want to be careful with the placement of the motor. If it is direct drive from the wheel to the monitor "frame" your motor (read big magnet) is going to be really close to your monitor. I would think this is a good argument for a belt driven system.
As far as size, you can get away with a fairly week motor since you are going to have some crazy reduction. If you have a disk supporting your monitor that is about 24" diameter and a 3" diameter drive wheel that's an 8:1 ratio.

Years ago I planned out how to do this, then lost intrest and just set up seperate vertical and horiz cabinets...My plan was to use a power window motor from a car. Just go to a junkyard and grab one out of just about anything. They are 12v and don't require alot of amps to move something geared down than much (probably cost you $10). Should be able to run off of a good 12v dc powersupply. My other plan was as allready mentioned, use a cordless drill, plenty of torque and easy to power once again. You can get a cheap one at any flea market or discount store.

i like your idea Sac01 of the power window motor from a junk yard. pretty much self contained. easy to power, reversable, decent speed, and already has a switch that can be mounted anywhere. although i have to admit if i was to do it myself i would be to lazy to take one out and end up buying an electric screwdriver to chop up.

is a pretty good shot of a stripped out window motor.
