Abstract
A method of forming tapered tubes for use as utility poles and the like comprises the steps of making a pair of cuts generally lengthwise of a cylindrical tube on opposite sides of the tube but offset at one end from a common diameter the same distance in the same direction and slanting the cuts so that at the other end of the tube they are on the opposite side of the same diameter, leaving a pair of tube halves having a small arc and a large arc at each end, reversing one of the tube halves to place both small arcs at one end and both large arcs at the other end, welding the halves to each other along the cut edges, and pressing the resultant tube to substantially circular cross section.
