Oops, my luck just ran out. MSC has no stock and isn't getting any
more, sigh. They're looking for me, they'll let me know tomorrow, but
as for now, I'm still looking for CBN plate mounted wheels.

Harold, please take it easy on me. I heard loud and clear that diamond
isn't the abrasive of choice for HSS, but lots of guys have told me
that borazon or CBN work really well for a finish grind. A Baldor No.
500 is a "carbide grinder" with tilting tables and plate-mounted wheels,
and it runs at 3450 rpm. which is *way* too fast to grind HSS with
diamond, yes.
