great link idea...
Yea Sammas - that's a really dinky idea; proving that often some of the simplest ones are the most effective.
I wasn't too worried about the altitude control, I thought that there would be numerous options for that (but I'll most probably give that one, or a version of it, a try.)
But my idea of a motor that is spring-loaded pressing against the azimuth board (anchored via a plate to the base-board) is something I'll investigate further: because the (rubber?) roller on the motor shaft would be a much smaller diameter relative to the diameter of the edge of the azimuth board's circumference, you would have good gearing for finite control, with the added bonus of the motor providing a degree of friction (braking) control when rapidly hand slewing without having to disengage the motor. This could entail freeing up the azimuth board's current fairly stiff movement to facilitate this type of conversion. There are some cheap, relatively "pokey" little 12 volt motors around.....
