I need to thread a piece of tubing and make a matching internal thread, I found formulas to calculate thread depth and came up with .047" for 13 TPI, I worked backwards from the ID of the tubing of 1.875 and added the wall thickness I want of .100" which gives me 2.075 for the minor diameter + .094 for the threads which gives me 2.169 for the major diameter. For the matching internal thread how do I calculate the initial bore size to start with?
I'm a threading novice, I just got my lathe set up to cut threads and cut my first one this morning.
