ABSTRACT:
A cam shaft made from lobes having irregularly shaped apertures spaced along the longitudinal axis of a hollow tubular shaft. The method of making the cam shaft includes the steps of: inserting a hollow tubular shaft through the apertures of a plurality of the lobes axially and radially with respect to the longitudinal axis of the shaft. The method is characterized by flaring at least a first end of the shaft and backing the exterior of the first flared end to prevent axial radial movement thereof. In addition, a plug means is inserted into fluid sealing engagement with the interior of the first flared end to sandwich the flared end against the backing of the exterior thereof. The hollow shaft is filled with liquid and the opposite ends of the shaft are clamped between the plug means at the first flared end and a fluid sealing means at the opposite end of the hollow shaft. Hydraulic force is then applied to the interior of the shaft to expand the hollow shaft into engagement with the apertures of the lobes.
