  • a first portion including a tapered stud having an outer surface;

    a second portion including a tapered cavity defined by an inner cavity surface which is sized to receive said tapered stud;

    means for securing said first portion to said second portion to provide discrete selectable angular orientations of said second portion relative to said first portion and for reducing angular motion between said first and second portions; and

    wherein said tapered stud is inserted into said tapered cavity to rigidly secure the second portion to the first portion by means of friction pressure between said outer surface and said inner cavity surface.
