    Patent number: 8904892
    Abstract: A mount for a shaft includes a collar, disposable around the shaft, a first mating piece and a second mating piece. The collar includes first and second tapered outer surfaces that taper away from each other. The first mating piece has a first tapered aperture that is configured to mate with the first tapered outer surface of the collar. The second mating piece has a second tapered aperture configured to mate with the second tapered outer surface of the collar. The first and second mating pieces are adapted to be aligned such that when the collar is mated with the first and second mating pieces, the shaft is substantially perpendicular to the first mating piece.
