Abstract:
1. An apparatus comprising: a substrate comprising a wall surface with an annular sidewall of a first aperture that extends through the substrate and has a first overall diameter; a rotatable member adjacent the substrate; an elongated member comprising a sidewall which extends adjacent the wall surface to form a first gap therebetween, the elongated member facilitating relative rotation between the substrate and the rotatable member about a central axis along which the elongated member is nominally aligned; and a reinforcement member comprising: wherein the substrate is characterized as a pole, wherein the reinforcement member is characterized as a spacer sized to nest within said pole, and wherein the elongated member successively and concurrently extends through a first side of the pole, through a first side of the reinforcement member, through a second opposing side of the reinforcement member, and through a second opposing side of the pole.
