Thanks Echoman.
Even if the tooth didn't appear blue from heat, it can still be hard on the surface.
Gday Echoman
Red here
I have a cheap grinder and have only sharpened about eight times with it
so far all is good
I see what your saying about blueing and curling
Its not as bad on the side of the chain where I cutting outside in with stone rotation but when you have to cut inside out as once you've rotated to the other side angle I tend to see a little more burring of the gullet or hook and the top plate
I did try to rum the grinder backwards but it didn't seem to like it much so didn't push the issue as I didn't want to blow the motor
I sharpen at 25 and 55 degrees for the most part they chains cut well and hold edge as good as any anyone else has done for me
I don't like seeing blueing at all but get some
sometimes
also how would a 20 degrees top plate angle go in dry hard wood would it slow the cut down n load to saw ?
I wondered also about cooling with either air or milling oil/water or just water
or do you think Im being anal and just to heavy handed with the feed
thankyou mate yeah
