Abstract
A turbo-machine having a means for attaching the blade ring to the casing at a plurality of alternative radial positions to provide for a plurality of alternative clocking angles for a stage of stationary airfoils. The blade ring is provided with a plurality of notches that may selectively be aligned with a pin inserted through the casing. By rotating the blade ring so that a selected notch aligns with the pin, a selected clocking position may be achieved. Assembly with a different clocking angle is achieved by aligning the pin with a different notch. The notches may be provided at any location around the blade ring so long as they are separated by a radial distance which is a non-integer multiple of the segment angle.
