    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 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.
