I do the same thing. I'm not trying to win a race, and it's not like I'm earning money doing this stuff. And, I don't thread often enough to be fully confident with it.
Ed, you might try cutting the thread again WITHOUT releasing the half nut. Cut the thread, stop the lathe, back the carriage out, reverse the motor, re-zero the carriage, make another pass. Works much better if you have a foot brake on your lathe. This way, the relationship between the lead screw drive train and spindle is preserved.
