ABSTRACT:
A saw-chain sharpening device is provided which is releasably attachable to a portable chain saw to enable routing-type saw chain cutters to be sharpened in situ on the chain-saw guide bar. The sharpening device comprises a support bridge clampable to the saw guide bar in a position straddling one pass of the chain. This bridge supports a grinding-wheel mounting arrangement which can be set up to orientate a grinding wheel carried thereby into the plane of the routing-edge face of a cutter to be sharpened. Once correctly orientated, the grinding wheel is driven in rotation by external means (such as a conventional electric drill) and approached towards the cutter along a path lying in said plane. This path is defined by a linear guide of the mounting arrangement, the guide being slanted at the undercut angle of the cutter face.
