A cylindrical probe which will take more accurate hits on thread holes.

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.

  • The thread holes I'm checking are fairly small, 3-48, so the only styli that will enter is the 1 by 10mm. I know I am picking up high and lows but just trying to get locations. So far my readings have been within tolerance but again, someone says the cylinder styli's the way to go and now I hear the engineer's muttering, "cylinder styli" over and over like it was the Golden Calf. Anyway, the genius's will be here sometime today so I might learn a joke or two from them.
