Darrell... I thought you might be interested in a tip that I picked up yesterday at the club meeting, regarding care and feeding of 3 point tools..
The guy doing the demo (a retired shop teacher) had a hex nut on the shaft of his 3 point tool.. looked sort of strange until he finished showing how to cut a bead and went to sharpen it... the flats of the hex nut sat on the grinder tool rest and lined up with the faces on the tool with the grinding wheel... Seemed pretty clever to me..
He said that you put the nut on before you shape the faces when you make the tool.. which would be a lot easier than the several ways that I tried, as you might remember.. *g*
