My father had an old pto driven buzz saw that we used when I was a kid. After he passed in 1999 I hauled it home to my place and parked it in a fence row. Got to thinking it might save me some labour cutting small diameter stove wood for my boiler. I hauled it out and am in the process of rebuilding it. It had a 4” tree growing thru the middle of it. Lol
I decided first off it needs a good sharpening. I scribed lines across the diameter to give me the proper angle of each tooth and then scribed another witness march at 43degrees from that mark for the relief and gullets. I hung a cable from the ceiling in the shop suspended the blade at the centre height of my wheel on the surface grinder and used a radius grinding wheel to grind the gullets free hand to my witness marks.
I ground the rake angle with a angle grinder and the cutting edge I filed by hand.
I had to remove the guard to have clearance for the gullets. A bit sketchy but I took it slow and steady.
I will post a picture of the finished sharpen tomorrow
Cheers
