Chainsaw Repair

One glimpse at the grinding wheel in these pictures tells me that the all important corner is dull and needs to have the dirty color lightly dressed from the corner and another light pass taken on the cutters before the chain sharpening is finished. I can tell that the top angle on the stone is dull because it has a dirty look to it right at the corner.



Even watching this video of the German sharpener, I can see the grinding wheel is dirty in the corner as Rich is taking pretty healthy cuts on the chain. He will need to touch up the stone and make a light pass on the chain before it is finished. You will notice that the top side of the corner gets dull first as it has to do the most cutting.
