Tooling holds a workpiece for the performance of a work step thereon or thereby, which supercenters the workpiece relative to a concentrically rotatable cylinder of an apparatus. A method of supercentering a workpiece utiliezs the tooling of the invention. The tooling has a workpiece clamping subassembly which is substantially centerable with respect to a centering member and then secured thereto forming a centering subassembly. The centering member has a centering projection which is supercenterable with respect to a holder by means of several axially normal adjustment screws engaging side surfaces of the centering projection. The holder has a cylindrical arm to be clamped in a collet chuck of the rotatable cylinder of the apparatus. The method utilizes slowly rotating the cylinder, thereby rotating the tooling and the clamped workpiece, and determining eccentricity of rotation thereof, and making appropriate incremental adjustments using the adjustment screws. Work steps may then be performed on or by the workpiece.
