Abstract: A method is provided for the fabrication of a steel propeller which is designed to have a final shape and size consistent with a conventional propeller design. The resultant formed propeller includes n individual blades, each having boss segments. When the boss segments of the individual blades are joined together they form a propeller having a center boss portion. A center aperture may thereupon be drilled or bored in the boss for mounting the propeller on the shaft of a marine engine. The propeller is formed, in accordance with the method of the present invention, by individually press-forging n steel blanks into individual blade portions which include boss segments. The press-forged blades are then ground with their lateral surfaces beveled to permit them to be welded together into a whole propeller. The center aperture is then formed and the propeller finally heat treated and finally ground.
