      Thanks for replying - I can definitely give that a shot. I was not sure if there as an actual need for the servo pot beyond centering the legs. If that is it, then I can definitely work with springs.

I have built the circuit and directly attached the legs to the shaft and they rotate back and forth, but of course there is no feedback pot as would be found in a servo. I can certainly use mechanical stops, but wondered how important it is to have the feedback pot and if I should improvise by adding one in some way.
