Scott,
I know this was a while back, but I just found it searching on "Good Wood". Were you using a 1/16 tapered ball nose with a 5% to 10% step over? I don't get as good a finish as you are and am trying to figure out why. I use a 1/16 tapered ball nose, 16,000 RPM, 10% step over, and I think 100 feed rate. Any suggestions?
