1. An adjustable stroke mechanism for a random orbital machine comprising:
a housing having a central axis and a wall enclosing a cavity;
at least one counterweight movably disposed within the cavity;
a mounting assembly disposed within the cavity, the mounting assembly including a workpiece attachment mechanism;
a stroke adjustor coupling the at least one counterweight with the mounting assembly, the stroke adjustor including an axially movable element that is rotatable around the central axis, the stroke adjustor enabling the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.
