Picture of Propeller: drill and attach blades

Stack the blades with the template blade on top, clamp them with at least two clamps, and drill 1/8" holes through the stack. Mount the blades on the wheel, starting all zip ties on the front faces so they can't snag the drive belt in a wind. Snug them down with low tension, and trim the loose ends.
