C's Tree Needs
While learning to grind chain, I see that dad seemed to have used a wheel/disk angle of 70/75 instead of recommended 60 on both the 3/8 full chisel (w/no 10 tilt) and 3/8 lp chamfer/semi chisel.
He started tree work in early 80's, so some might call him "old school" in his ways. All I know for sure (through working for him for years w/o explanation of techiniques) is that his chains cut well, but were real "grabby" (he liked to take the rakers down quite a bit when he ground them).
Any insight as to why he did this? My only conclusion is that maybe he would get a little more life out of the chisel.
