ABSTRACT:
A method of forming a camshaft tube having a plurality of thinner wall sections adjacent to thicker wall sections. The diameter of a hollow tube is mechanically reduced with a retractable mandrel inserted in the hollow tube. The retractable mandrel has a first portion having a larger diameter than an adjacent second portion. To form a thinner wall section, the larger diameter first portion is positioned under a reducing tool. To form a thicker portion, the smaller diameter second portion is positioned under a reducing tool.
