      Am I really going to need to allow for millionths of an inch ? I'm   
   looking at an 81 piece set from Shars , a grade B with the deviation   
   table for under a hundred bucks . Looks like the biggest variance is   
   .000034" , or about a third of a ten thousandth . I can't see any   
   project that I might get needing that kind of precision ...   
      I'm considering buying the set just because I've kinda wanted some   
   and I think they'll get me closer to perfect in my upcoming depth mike   
   project . Since they can trace back to a national standard I can also   
   use them to check all my other micrometers , none of which have been   
   calibrated for at least 40 years , and in some cases longer than that .

     It's great to be straight !
