Thanks RRR!

I posted that because some on the forum think CNC is the be all- end all, but anybody with actual experience with his stuff knows that you can still get good results with these stone aged machines, if you take care of them and take the time to set things up right. The CNC surely would save time though. I know you and YR and some others get it.

Well WTH did guys do before CNC? Old school, that's what. Some argue with the coveted Serdi machine against the old Sioux stone type valve dressing machines. How many millions of valve jobs have been done with stones and are perfectly fine?
