The flange 50 extends to a rim 58 and has a plurality of pairs of first and second weight-mounting fastener apertures 80A,82A,80B,82B. A plurality of first recesses 84 are provided in the rim 58, each position between an associated first and second aperture 80a,82A of an associated one of the aperture pairs. A plurality of second recesses 86 are provided in the rim 58 each positioned between an adjacent two of the pairs 82A,80B. Also disclosed is a method for remanufacturing existing turbine disks. |
