...But it's enough for the board house to balk at, even if they can't mfg to those tolerances.  Oh well, released a slightly modified Gerber to deal with some "roundingness" in the mfg outputs and ensure things are a little cheaper overall (under 5 mil costs more).  Bugger.  Nothing like a finicky board shop to slow you down.  Bet that eats into my "rush" time.   pfft  :|
