Claim 20:
21. 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; and
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,
wherein the at least one drive comprises:
a first drive coupled to the head by a shaft and configured to impart the rotation to the head in a first rotational direction about the longitudinal axis, and
a second drive coupled to the housing and being configured to impart the rotation to the housing in a second rotational direction, opposite to the first rotational direction, about the longitudinal axis.
