Hi Roy and thanks - some good ideas here.
As a guide for people who go down this design path, how many degrees of alt (and az) do you move the scope for each full turn of the knob (and handle)?
Obviously people can design different rates by choosing different threads and sprocket sizes. Did you arrive at your choices through trial and error, or would you choose different ones if you were building version 2?
Cheers
Andrew
