Abstract
Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
Claims5
A method, comprising:
- pressing an actuator of a saw chain sharpening fixture against an environmental object to apply a linear, non-rotary actuation force directed toward a nose portion of a guide bar in a direction parallel to a longitudinal axis of the guide bar,
- wherein the actuator is to, upon receipt of the actuation force, linearly move a sharpening element of the saw chain sharpening fixture towards one or more cutting links of a saw chain as the one or more cutting links traverse the nose portion;
- and
- sharpening, by the saw chain sharpening fixture, the one or more cutting links of the saw chain.
