Herein disclosed is a centrifugally cast pole having a substantially uniform wall thickness along the long axis of the pole. During centrifugal casting, molten metal is poured inside a rotating, tapered mold. As chilled liquid is poured over the outside of the rotating mold, the metal forms, or paints, to the contour of the mold interior creating a metal pole. By precisely controlling casting gyrations such as the spin, travel, pitch, and yaw of the rotating mold and the calibration and physical mechanisms of the casting machine, hollow, tapered, tubular metal poles are produced with previously unknown uniformity of wall thickness. The controlling principles, designs, and mechanisms of this centrifugal casting method enable wall uniformity to extremely high tolerances. By extension, the ability to precisely control the metal volume painted inside the mold allows, as a design choice, wall thickness variation in any embodiment if so desired.

1. A centrifugally cast, hollow pole comprising: an elongated, hollow, conically tapered pole member which is formed by centrifugal casting so as to have a substantially uniform wall thickness throughout the long axis of said pole member, said pole member comprising a plurality of asymmetric pimples extending away therefrom, that is formed by centrifugal casting. 2. The apparatus of claim 1, said pole member having a variable outside cross-sectional dimension that varies perpendicularly to said pole member's long axis. 3. The apparatus of claim 1, said pole member having a first end and a second end, said first end having an end cap. 4. The apparatus of claim 1, said pole member having a first end and a second end, said second end being flanged. 5. The apparatus of claim 1, said pole member having a first end and a second end, said first end having a slip joint with an internal cross-sectional dimension sufficient to allow said first end of said pole member to slidably receive the second end of another said pole member. 6. The apparatus of claim 1, wherein the apparatus is manufactured from a castable material. 7. The apparatus of claim 6, said castable material is selected from the group comprised of ductile iron, cast iron, steel or aluminum. 8. The apparatus of claim 1, said pole member including a panel to allow access to the hollow interior of said pole member. 9. A centrifugally cast, hollow pole comprising: an elongated, hollow, conically tapered pole member which is formed by centrifugal casting so as to have a substantially uniform wall thickness throughout the long axis of said pole member, said pole member comprising an outer surface comprising a plurality of pimples extending away therefrom, said plurality of pimples are formed during the centrifugal casting of said member.
