A workpiece positioner is provided including a positioner chassis, a specially designed rotary framework, and first and second sets of workpiece supports. In accordance with one embodiment of the present invention, a workpiece positioner is provided comprising a positioner chassis, a rotary framework, and first and second sets of workpiece supports. The rotary framework defines opposite rotary framework ends and is coupled to the positioner chassis so as to be rotatable about a longitudinal framework axis. The first set of workpiece supports is positioned on opposite ones of the rotary framework ends so as to define a first workpiece axis extending between the first set of workpiece supports. The second set of workpiece supports is positioned on opposite ones of the rotary framework ends so as to define a second workpiece axis extending between the second set of workpiece supports. The first workpiece axis and the second workpiece axis lie in a common workpiece plane. The rotary framework includes a crossing structure secured to the opposite rotary framework ends and extending along the longitudinal framework axis. The crossing structure comprises supportive sheet material. The supportive sheet material is arranged so as to be intersected by the common workpiece plane. A transverse cross section of the supportive sheet material converges in the direction of the common workpiece plane.
