ABSTRACT:
A jig is structured to guide a grinder along the inner surface of the base or cover of a combustion turbine. The jig includes a base having a bottom surface with a plurality of rollers arranged in substantially the same radius as the portion of the casing being repaired. Side rollers locate the base horizontally during movement. A top platform may restrain the base vertically by supporting a pivot block that bears against the rotor of the turbine. The grinder may be moved vertically or horizontally with respect to the base upon which it is secured.
