Thanks Ken,
The blade sticks out of the holder only 1/8" beyond what's needed, there is no compound and the whole setup seems rock solid and over-engineered.
I can cut steel even stainless easily with the same setup.
Also I'm not new to using a parting tool, my first time was 45 years ago although I'm not a machinist. It really sounds to me like I need to change the top rake is the answer.
I'm finished with that little job and going into milling mode but when I get back to lathe I'll try a new grind and report what I find. I'll also reduce the clearance angle as suggested. That may be a biggie. The carbide tips that work so well for external turning have no clearance angle.
