Abstract:
A method of reciprocating a spindle of a reciprocating saw, the reciprocating saw including a housing, the spindle having an end adapted to support a saw blade for reciprocating movement relative to the housing, said method comprising the acts of:reciprocating the end of the spindle such that the saw blade moves along a first path of travel relative to the housing during a first cutting stroke and along the same first path of travel during a first return stroke; and reciprocating the end of the spindle such that the saw blade moves along a second path of travel relative to the housing during a second cutting stroke and along the same second path of travel during a second return stroke, the second path of travel being different than the first path of travel; wherein the saw blade is selectively supported by the end in a first orientation relative to the spindle to have a first cutting direction and in a second orientation relative to the spindle to have a second cutting direction opposite the first cutting direction, wherein said first path of travel is characterized by movement at least partially in the first cutting direction during the first cutting stroke, and wherein said method further comprises the acts of: adjusting the orientation of the saw blade relative to the spindle from the first orientation to the second orientation; and changing the path of travel such that the end moves along a third cutting path relative to the housing during a third cutting stroke, the third cutting path being characterized by movement at least partially in the second cutting direction during the third cutting stroke.
