A lightweight composite camshaft has stamped sheet metal or other lightweight journal and/or cam elements having locating hubs and assembled onto a hollow tube. An economical and rapid method of assembly uses indexing balls pressed into accurately positioned blind holes in the tube and grooves in the bores or hubs of the cam elements to angularly locate the cams with precision prior to locking them tightly in place by expansion of the tube.
