Abstract

A slip joint including telescoped inner and outer members having substantially unstressed plastic material interposed therebetween. The joint is made by first telescoping inner and outer members with the plastic material interposed therebetween. The outer member is then deformed inwardly to place the plastic material under considerable compressive stress. The deformed area is then heated for expanding the plastic material and relieving the compressive stress by plastic movement of the plastic material. The plastic material is then cooled and minimal sliding clearance is provided between the inner member and the plastic material. The outer member is thus deformed inwardly in at least one localized area and the plastic material has a thickness beneath the deformed area which is substantially less than the thickness thereof beyond the deformed area.
