ABSTRACT:
A system for aligning and regapping the guide grooves on a chain saw guide bar which includes a suitably adapted handheld swaging tool uniquely designed to return bent or worn guide grooves to the correct position and separation. The swaging tool contains a gauge which is adapted to fit in the center of the bar guide groove and a pair of swaging plates which are adapted to force the walls of the bar guide groove into proper relationship with one another upon the application of force to the swaging tool. The system may optionally further include a bar file guide which is adapted to file the peripheral edges of the chain saw bar.
