ABSTRACT:
The invention provides a blade-rotating device for rotating a plurality of radially-oriented blades having a blade base with two grooved base sides. The device has a portion, such as a disc or a rotor disc of a turbine, for rotating the blades with the portion having an outer cylindrical surface. The device also has a plurality of steel steeples each having a steeple base and two opposite grooved steeple sides extending therefrom. Each of the opposite steeple sides complements at least one of the grooved sides of at least one of the blade bases. The steeple bases are linear friction welded to the outer cylindrical surface in an approximately longitudinal direction such that the blade bases are engagable with the steel steeples.
