A tapered bushing includes a conical inner surface defining a conical axis, and a radial direction. The tapered bushing further includes an outer surface of revolution, and defines a minimum radial wall thickness that ranges from 3.0 mm to 15.0 mm measured from the conical inner surface to the outer surface of revolution. Also, the conical inner surface defines a draft angle that ranges from 2.0 degrees to 30.0 degrees.
