I never would have thought of that, Eric. Thanks! I'll try grinding
the top a little.

You usually don't want to grind the top especially if this is the long
blade type. Grind the front face back. Also, a machinest aquaintance
told me to experiment with the angle of the front face (i.e. front
clearance). There is an optimum for best cutting versus chatter. I
found this to be true.
