Patent number: 9216481Abstract: A method of creating an arbor mounting hole in a blade. The arbor mounting hole is created by making a first model of an arbor mounting hole that fits onto the asymmetrical mounting arbor. The first model has a first long flat edge and a first center of rotation. A mirror image of the first model is used to create a second model. The second model has a second long flat edge and a second center of rotation. The first model and the second model are superimposed so that the first center of rotation aligns with the second center of rotation and the first long flat edge aligns with the second long flat edge. The superimposition creates a compound model. A symmetric arbor model is formed about the compound model. The symmetric arbor model is cut into the blade.Type: GrantFiled: March 5, 2010Date of Patent: December 22, 2015Inventor: Edward A. Zuzelo
