Abstract: A pivoting ball mount provides four essentially equal and (generally) evenly spaced constraints on the ball, creating a ball and socket joint in which the “socket” is composed of four small constraining pads of equal size and equally spaced around the surface of the ball or sphere. If a sphere is constrained by four equidistant points, each point will exert the same amount of force on the sphere. If additional pressure is applied to one point, the pressure exerted by the other points will rise to match this increased pressure. The effect of constraining a smooth ball by four equidistant points is to create the equivalent of a ball and socket joint in which the force required to rotate the ball at a particular rate is about the same in any direction. The ball is constrained by four equidistant points such that the relative movement between the ball and housing is smooth and predictable in any direction.

In this way, the same mount may be used with either fine adjuster screw or ultra-fine adjuster screws by simply interchanging core bushings having the corresponding pitches.
