I need to indicate an internal thread. It is a 2 1/4-8 thread and it is on a backplate. Someone bored the register off center and I need to bore and resleeve the backplate but the register bore has got to be on the same centerline as the thread to make this work. I have the back plate set up in the 4 jaw now I just need to figure out how to dial it in so the bore and the thread centerline line up. Any suggestions greatly appreciated. Thanks, Steve
