Abstract
A cylindrical article is positioned relative to a support surface by supporting the cylindrical article from a first pair of ball bearings contacting the cylindrical article adjacent to its first end, and a second pair of ball bearings contacting the cylindrical surface adjacent to its second end. At least one of the ball bearings is moved relative to the cylindrical article to reposition the cylindrical article. The repositioning may be performed under feedback control of actuators that move the ball bearings. The article may be fixed relative to the support surface after it is properly positioned.
