[QUOTE="moonbase, post: 1124924, member: 178786"] Not everyone, see my reply in post 162 above. The two actuator fixing points and the bearing rotational axis point define the scalene triangle of the actuator plane. Two sides of this triangle are of fixed length that does not change. The remaining side of this triangle changes as the actuator arm extends and retracts and so does the E/W angle that the dish is aiming at. By adjusting the location of the actuator fixing points, the sensitivity of actuator movement and E/W sdjustment can be increased or decreased. It is simply a matter of how much the thread pitch inside the actuator moves the arm and how much change of E/W degrees are associated with the thread pitch for the scalene triangle setup on the mount. Different size scalene triangles on a mount will have different levels of sensitivity. [/QUOTE]
