ABSTRACT:
A propeller is mounted on a vertical bolt on one end of a table. A horizontal radial wedge under the table is actuated by an hydraulic cylinder to tighten the bolt and clamp the propeller against rotation. A head frame is movable along the table by an hydraulic motor. An anvil beam and a presser foot beam are movable vertically in the head frame by hydraulic cylinders to clamp a blade of the propeller, remove dents, twist the blade and perform other operations as may be necessary to repair a damaged metal marine propeller.
