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.
I would still argue that the "Threaded Gage" method is the most accurate, followed by using "Auto Circle with a Pitch" as Ninja described with a Ruby Ball Stylus (We are going to look into that option today). For option #3 I would still go with the cylinder stylus (We are measuring holes as small as 2-56 with the stylus I described above).
