1. The adjustable stroke device for a random orbital machine comprising:
a housing having a central axis and a wall defining a cavity;
at least one counterweight movably disposed at least partially within the cavity;
a mounting assembly disposed at least partially within the cavity, the mounting assembly including a workpiece attachment mechanism; and
a stroke adjuster coupling the at least one counterweight with the mounting assembly, the stroke adjuster enabling the at least one counterweight and mounting assembly to move with respect to one another such that a distance between the at least one counterweight and the mounting assembly may be variably adjusted which, in turn, variably adjust a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing, the stroke adjuster including an adjuster ring and a cam mechanism fixed to the adjuster ring.
