Claim Text:
1. A method for determining internal diameter of a ring-shaped, dampening cone for gas turbine engine, comprising: providing a measurement fixture, which includes: resting an axial end surface of a ring-shaped dampening cone of a gas turbine engine upon the elevated, planar reference surface of the base, supported in an elevated position by hanging an inner radial surface of the dampening cone in abutting engagement with only the single locating pin's single contact surface, while an opposite side inner radial surface thereof abuts against and circumscribes the displacement indicator's displaceable point; and determining the dampening cone inner diameter by swinging, in pendulum-like fashion, the dampening cone relative to the locating pin single contact surface, the dampening cone inner diameter constituting distance from the locating pin's single contact surface to the displacement indicator maximum-extension displacement reading.
