Thank you guys so much!! I read each post and jotted everything down. Right after dinner today I chucked up some steel and turned it down to dimension. I adjusted the compound slide to 60.5 degrees and mounted a dial indicator.
After the initial scratch pass I disabled the motor and turned the thread by hand. I continued to turn the chuck and dial in the compound a little at a time until it started looking like a thread. Aside from my forearms aching I feel good about the end result. Not as finished as maybe it should be, but the nut fits and moves smoothly.
I feel confident the next project I need to make threads I will be a able to. Thank you!!!
