An apparatus and process is disclosed for spinning circumferential articles with constant length end surfaces. The article is first spun to define the circumferential surface, and a mandrel is then introduced, whereby the mandrel has a shoulder positionable adjacent to the end surfaces. The end surfaces, while supported by the mandrel, are further spun, and the material is flow formed into the shoulder, to define a constant and defined length to the article.
