I just know there is a spreadsheet/calculator or software app. to calculate various parallel heel graver dual angle fixture settings, inputting different lift (relief grind), face angles ect. to give heel yaw angles...example inputting 4 degrees lift, 105 degree v point, 55 degree face to find optimum relief grind angle and optimum heel angle and proper heel yaw angle....
