摘要： This invention is concerned with a work holder for a slotted tube to be deformed, preferably by moving the tube to a deforming work station and preventing the tube from rotating. The tube is fitted with an internal mandrel which is held in a fixed position by a vice. The mandrel has an upright blade that extends through the keyway of the slotted tube so that the tube can be slid along the mandrel relative to the deforming work station. In one method, continuous lengths of hollow pipes, tubes and the like can be threaded or otherwise externally deformed by supporting the workpiece internally with the mandrel. By changing the mandrel size, tubes of varying diameter can be accommodated. The deformed workpiece can be used in a variety of applications, one of which is a threaded hollow tube or stem member that has a cap welded to the rim of the tube to provide a pedestal cap of improved strength.
