Has anyone tried freehand grinding of lathe bits (those with inserts

Still, from hanging out on the
Quorn groups and such, I see that people use diamond wheels on HSS.

Only those with little in the way of brains. As you alluded, diamond is

VERY low. The change in grinding ability of a diamond wheel that is so
abused is readily noticeable--assuming you understand the difference.
