That's the email I got upon entering the shop today. I was using a 1 x 10 styli for a part with 3-48 & 6-32 threaded holes. Just trying to get a decent location within tolerance of +/- .005. Now, the customer (we are the sub-contractor) is "coming in today with a cylindrical probe which will take more accurate hits on thread holes". I checked some of the postings in the forum and it looks like there's a lot involved and the results are sketchy.
A "shank" probe will only give you the location of the minor diameter. I have watched thread locators pulled to one side, for a variety of reasons. How would one check an 0-80 thread using auto-circle/pitch, or similar threads. Engineers truly need to stop attaching unrealistic tolerances to thread locations. My favorite is when they attempt to apply MMC to a threaded hole. Good luck with THAT one.
