Measuring an internal thread
#6
I recently cut a special thread using this very technique. It was a .900-32 3B thread, so I calculated the pitch diameter of the external thread and made a gauge to the high side of the 3A tolerance, then cut the internal thread using the gauge to size it. Worked like a champ.
