Ok thanks, I did take 3 spring passes each time I adjusted the boring head out. I did only run it at 250RPM so that may have been way too slow! I will centre the piece back up in my mill and crank her up a bit and try again! Only thing I am worried about is making the hole bigger then what it already is.... Oh ya I would of tried to do all this in my lathe but the piece I am working on wouldn't fit in the chuck.

Is your boring head calibrated for radius or diameter cuts? If its calibrated for radius cuts and you had it set for .014, then it would had cut the hole .028 bigger (in diameter).
The fact that it cut .030 when you were expecting .014 sounds like this is worth checking.
