On a few occasions, Bill Palumbo has displayed his handy work in marble. I finally found the time to do some tinkering today. I masked with adhesive shelf liner, 60 degree V bit at 13000rpm at 1.5 in/sec. I used two passes to get to the final depth. The only problem I encountered was that the tip of the bit did not hold up. McKenna was the first name I cut and the corners are nice and crisp. By the time I cut the third name, the tip if the 60 degree V went away and as a result, the corners are a little soft.
