Abstract: A method for producing a scaled-up solid model of microscopic features of a selected surface. A selected surface on a piece of metal exposed to friction, for example, is scanned with a profilometer along X, Y, and Z coordinates to obtain measurements of surface features. A 3-D high resolution spatial map of the surface features is made and the X, Y, and Z measurements are scaled up as desired. The spatial map is transposed into a high resolution 3-D scaled-up meshed surface. A data set of printing instructions is made from the 3-D scaled-up meshed surface acceptable for use in a 3-D printer. A solid scaled-up model of the selected surface is manufactured in the 3-D printer in any desired size using the printing instructions. The method provides a physical hand-held model of the selected surface that can be used to demonstrate accurately the effectiveness of lubrication and anti-friction products, both visually and by touch.

Abstract: Disclosed is a utility pole formed as a hollow tube having a pentagonal exterior surface with the junctions of the sides of the pentagon each forming a dove tail channel. An interior surface of the hollow tube is round to allow insertion of round reinforcing sleeves. A mounting member is configured for attachment to the dove tail channel on an exterior of the hollow tube by means of a cam fastener system in an interior of the mounting block. The cam fastener system has a plurality of cams mounted rotatably on a pair of hinges, configured to allow the cam fastener system to open and close in an interior of the dove tail channel. The cam fastener system can be directly inserted into or removed from a dove tail channel anywhere along the length of the dove tail channel by closing it. The cam fastener system fastens the mounting member to the dove tail channel by opening the cam fastener system when it is in the interior of the dove tail channel.
