ABSTRACT:
A tool for locating a predetermined number of turbine blades in relative operative position with each other includes a base with a space and walls with a space between them. Blades are located sequentially and adjacently. An arc of curvature is representative of the arc of curvature for a rotor for accommodating the blades ordinarily. When the blades are located, the curvature of the top conforms with the curvature of the rotor. The blades can then be adjusted and aligned such that when located in the rotor they will be accurately positioned. With a serrated root, the root is located near the plate and held with steeple screws. With a forked root, there is a post between the fork. A finger root is secured between sidewalls.
