Claims
- 1. A fixture for forming a turbine rotor having stacked axially aligned wheels and spacers, each of said wheels and spacers having a plurality of circumferentially spaced circular openings thereabout for alignment with one another, comprising:
- a support having an axis for registration with axes of the aligned wheels and spacers; a plurality of alignment rods spaced radially from and extending generally parallel to the axis of the support and circumferentially spaced from one another about said axis, said rods being located about said support for reception in the openings through wheels and spacers;
- each of said rods having a cross section normal to said axis and a maximum dimension in said cross section in a radial direction less than a maximum dimension in said cross section in a circumferential direction such that spacing between the rods and margins of the circular openings in said radial direction is greater than spacing between the rods and margins of the openings in said circumferential direction.
- 2. A fixture according to claim 1 wherein said rods having linearly extending sides.
- 3. A fixture according to claim 1 wherein said rods are generally hexagonal in cross-section.
