Abstract:
A method for positioning a cutting blade mounting boss on an exterior surface of a circular rotor block having a polygonal center bore, comprising the steps of:establishing an axial center of said rotor block;establishing a pair of vertex points for a face of said polygonal center bore;defining a triangle between said axial center and said pair of vertex points, said face of said polygonal center bore establishing a base of said triangle;bisecting said base to establish a facet centerpoint, said facet centerpoint and one of said pair of vertex points defining a base segment;bisecting said base segment to establish a facet quarter-point, a radial projection from said axial center through said facet quarter-point defining a facet quarter-line; andcentering said cutting blade mounting boss over said facet quarter-line on said exterior surface of said rotor block.
