A method of manufacturing a turbine nozzle for obtaining a predetermined value of throat area between adjacent ones of nozzle vanes includes providing a first vane, providing a datum for locating the first vane relative to an adjacent vane in the turbine nozzle, and fixturing the first vane relative to the datum for providing a trailing edge nest having six supports for predeterminedly locating the first vane relative to the adjacent vane. The trailing edge nest includes four trailing edge supports for locating the vane trailing edge to define a hinge axis extending along the trailing edge about which the vane is rotatable. A radial support radially locates the vane, and a throat support predeterminedly locates the vane about the hinge axis for obtaining the predetermined value of the throat area.
