It's the only sensible way to drill holes IMO. But drilling before 
etching makes no sense to me. CNC drilling seemed to have been high on 
wish lists in the group until the resident machinist declared that any 
backlash greater than .001" (or some similar nonsense from his 
textbook) just wasn't going to cut it. Surprisingly, he seems to still 
drill by hand.
