Abstract
First and second pairs of rollers are adjustably positionable along a pair of guide tubes within a fluid-filled tank in aligned, end spaced relation. A cylindrical workpiece resting within the interstices of the two pairs of rollers is incrementally rotated by an electro-hydraulic step motor. A sonic transducer scans the workpiece longitudinally with the workpiece being rotatively indexed successively after each scan.
