A spacer for attaching a first rotary blade and a second rotary blade to a rotary blade saw comprises a main block having a first side and a second side, the first side and the second side being parallel and the main block having with a bore through the center of the block in a direction perpendicular to the first side and the second side, the bore being a center point of the first side and the second side. 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. |
