Re: How to construct a turret?
We had a turret for Lunacy - essentially, we took a lazy susan and riveted some belting around the outside. That belting went out to a small sprocket on a slow turning motor. Hook up an encoder to that motor, and you have some great control - due to the size difference (12" outer diameter for the lazy susan, 1 inch diameter for the motor sprocket), it took a ton of turns of the motor to get the turret through its entire arc, which allows you a lot of precision.
