There is a first protrusion extending from around the bore on the first side, perpendicular to the first side, the protrusion sized to fit into a center hole on a the first rotary blade. A second protrusion extends from around the bore on the second side, perpendicular to the second side, the second protrusion sized to fit into a center hole on the second rotary blade. |
