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 sidewalls with a space between them. Blades are located sequentially and adjacently between the sidewalls so that the blades are accurately and snugly located between the sidewalls. The top of the sidewalls has an arc of curvature representative of the arc of curvature for a rotor for accommodating the blades ordinarily. When the blades are located in the space, the curvature of the top of the sidewalls 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.
