Electronics is still not sorted out 100%, I discovered the minimum head speed is ~ 180rpm, too fast for threads..


It sounds like youre getting there, and by what you are doing will be way better than stock lathe. Imagine the person that cant problem solve and fix things would be getting sick of sending things back

My lathe has geared speeds and 160 is the slowest, no brake, so it just winds down when turned off. I thread away from the chuck. Same set up except tool is upside down and you run the lathe in reverse. Start from the run out for the thread. Make a carriage stop so you start in the same place each time. This way you can thread right up to big shoulders, or in bores you you can thread a blind hole up to the end. Much simpler and you dont have to worry about quick winding out or crashing the tool. (On bores thread off back face with an opposite hand bar and thread is always visable). Speed is then not an issue and most things cut better with a bit of speed.
