But, unless you are using a pre-WWII made lathe, most modern lathes have a simple solution to switch between metric and "std" threads. Move a lever or at the most swop out the lead screw transfer gears and that takes seconds or at the most, 10 or 20 minutes.
I taught it to my machine shop students. If my "Juvenal Delinquents" could learn the procedure, certainly a practicing Gunsmith should be just as capable.
Apparently my gunsmith has a Pre-WWII machine!
He went on and on about how difficult and what a PITA it was to change the gears! Maybe its time I find a new Gunsmith!
