Claim 0:
1. An apparatus for removing rubber stator material from inside a housing, the apparatus comprising:
at least one drive configured to impart rotation about a longitudinal axis;
a head being passable at least partially inside the housing along the longitudinal axis of the imparted rotation;
at least one blade pivotably connected at a pivot point to the head, the at least one blade being pivotable about the pivot point at a plurality of pivot positions relative to the longitudinal axis and being configured to remove the rubber stator material at least partially from inside the housing along the longitudinal axis of the imparted rotation;
an actuator associated with the at least one blade and being configured to adjust the at least one blade to any one of the pivot positions relative to the longitudinal axis, the actuator comprising:
a piston having a shoulder disposed on the head, the shoulder being movable against the at least one blade; and
a source disposed in fluid communication with the piston and supplying fluid pressure to the piston, wherein the shoulder is movable against the at least one blade in response to the fluid pressure supplied from the source to the piston; and

a shaft on which the head is disposed, the shaft communicating the fluid pressure from the source to a pressure chamber of the piston disposed on the shaft.
