Docket No. 0639-IR-TH The nozzle has a full complement of blades, for use, for example, in a compressed-air turbine. However, a pair of peripheral walls, at opposite sides of the nozzle platform block nozzle blade groups. The walls prevent fluid flow through those blade groups and, consequently, the nozzle has limited power. The method teaches the machining away of as much of the walls as is necessary to enhance the power of the nozzle by exposing more of the nozzle blades to free fluid flow therethrough. By providing such walled, fully bladed nozzles, and removing portions of the walls, one can meet any power requirement, from full power to any practical minimum; by removing the walls entirely, or removing only a minor portion of each, respectively.
