22 53,732 ABSTRACT OF THE DISCLOSURE A method is provided for forming a circular array of rotatable blades from blades having an integral shroud with a leading planar surface and a trailing planar sur- face, the leading planar surface being generally parallel to an axial radial plane passing through the center of the root of the blade and the trailing surface, if extended, intersecting the axial radial plane passing through the center of the root of the blade to form an angle generally equal in degrees to 360 divided by the number of blades forming the circular array. Strict radial alignment is provided by assembling the complete blade row such that all blade center lines coincide with the groove center lines, with the shroud mating surfaces in complete contact and in tangential compression.
