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.

Claims (12)

1. 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.

2. The method of claim 1 , further comprising:

attaching, by an attachment member of the saw chain sharpening fixture, the saw chain sharpening fixture to the nose of the guide bar, wherein the attachment member of the saw chain sharpening fixture includes at least one guide pin and at least one latch pin.

3. The method of claim 2 , further comprising:

guiding, by the at least one latch pin, the sharpening element along a predetermined linear path to facilitate the sharpening.

4. The method of claim 1 , further comprising:

providing a spark arrester of the chain sharpening fixture to help resist emission of sparks from exiting a housing of the chain sharpening fixture.

5. The method of claim 1 , further comprising:

guiding, via one or more guide members of the saw chain sharpening fixture, the sharpening element of the saw chain sharpening fixture along a predetermined path to facilitate the sharpening.
