Abstract
Construction of impellers of various dimensions are manufactured from tubular hub stock and sheet-like blade stock by cutting a hub of particular length from said hub stock and blades of corresponding length from said blade stock and attaching said blades to said hub. The bore of the hub may be enlarged according to a specified support shaft diameter, and the overall diameter of the impeller may be altered, preferably by trimming ends of the blades prior to mounting on the hub.
