Was cutting a female thread 3/4'' x 40 tpi. Male part was already threaded.
Did the calculations for how much to crank the cross slide for the proper thread depth. Couldn't see very well how the threads were forming so I trusted my calculations and hand wheel dial. I wanted a close fit so I stopped ,020'' short of my calculation to sneak up gradually on final dimension. Figured to do trial fits from there on and after each very shallow cut.
But the first trial fit perfectly. No need to make...
