Hey Mike,
I think Cutter should do one of those machining books. We could all learn a lot.
I saw a you tube video of a hss cutter ground to the shape of a tangential cutter for a QCTP tool holder, 30 deg top rake, 30 deg back rake, 5 deg left side relief and 5 deg front relief. I am going to try it on a barrel as soon as I progress a bit. Will let you know how it works.
If Cutter is lurking, the Yoke is on him.
