I'm contemplating motorising my DIY dome and have started searching for a suitable drive motor/gearbox. I plan to apply pressure to the final drive wheel to bring it up under the steel ring on the base of the dome, and hope that this method will provide enough friction to drive reliably.

Has anyone else found a suitable motor/gearbox combination, or would it be best to use a motor and pulleys? I would also be interested in a variable speed drive so that I could ramp up/down the speed, and use an appropriately low speed for tracking purposes, and a faster speed for moving the dome around to line up with a new target object.

Any thoughts welcome.
