Abstract
The method is performed on a cylinder having at least one end opening for receiving a flange forming tool. An annular shoulder is formed extending from the outside of the cylinder substantially perpendicular to the axis of the cylinder. Also, an annular extension is provided on the cylinder having an outside surface extending from the inside of the annular shoulder to the end of the cylinder. The length of the outside surface is formed to be greater than the radial width of the annular shoulder. A flange forming tool is then applied against the free end of the annular extension to move the annular extension until its formerly outside surface is against the annular shoulder to provide an end flange extending substantially perpendicularly to the axis of the cylinder.
