Go for it!
One really doesn't need the octave markers on every setting...I figured that I would know if I turned past a + or a - that I would be in that specific octave.
Hell, I probably could have omitted the U on each of those too.
This one got a little...eh...I tried milling the holes with the CNC. Maybe my speeds and feeds weren't set right...but my bits couldn't hang. I ended up rounding over the flutes after the first hole.
Gonna try a different approach next time.
