Abstract
A damped drive shaft is produced by forming a cylindrical tube of selected length and diameter, inserting a damper into the tube and positioning it at a central location within the tube, fitting a deformable plug into each end of the tube, and swaging the ends of the tube to reduce their diameter and deform the plugs to effect a seal at the opposite ends of the tube. Following the swaging operation the reduced diameter ends of the tube may be faced and washed. Thereafter, the plugs may be removed whereupon the drive shaft is ready for further processing.
