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 at least one counterweight and mounting assembly move with respect to one another to adjust a distance between the at least one counterweight and the mounting assembly which, in turn, variably adjusts 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.
