According to exemplary inventive practice, a frame has a geometric vertical axial plane and supports a receptacle, four thumbscrews, and four dial indicators. Each thumbscrew has a dial indicator associated therewith and can be turned to move along its geometric axis, perpendicular to the vertical axial plane. The thumbscrews are paired, with respective axes aligned, on opposite sides of the vertical axial plane. The frame is placed upon a base, the body is secured to the frame using the receptacle to grip a portion of the body, and the dial indicators are calibrated for matching thumbscrew displacement measurements in each opposite thumbscrew pair. The thumbscrews are moved into contact with the base and are adjusted to align the body with the base, as indicated by matching dial indicator readings in each opposite thumbscrew pair. The aligned body is affixed to the base, and the frame (with accompanying components) is removed.
