Yup,?
You are right. I just re-watched this video from Abom79. He does the metric threading on his imperial lathe, starting at minute 11:40.?
He does start at the same number (1 in his case, with the blue dot), but he DOES NOT disengage the half nuts.?

Small job requiring some 12mm titanium rods to be threaded on both ends for an M12x1.25 pitch. I wanted to show more detail on how I set up and operate the Victor lathe when I'm machining metric threads. I use the technique where I disengage the half nuts after
each pass. My Amazon store where I'm adding many of the tools and products I use in ...

Too bad it isn't true.

Yes, that is the plan, anyway. ?
Are you saying you can just disengage the half nut, hand crank the carriage back, and restart on the same number?

The only difference between metric and imperial on using threading dial is that with metric you have to start ON THE SAME mark, every time.?

I had that idea a while ago as I had some parts to make that would have been easier to leave in the chuck and go back and forth to the lathe and mill. I considered using carbide tooling to thread a commercial hex block as there was sufficient wall thickness
for the threads. I never got around to it but it is still in the back of my mind. If I had a surface grinder making one would be much easier. I have a 10k and have used the printed gears from Ebay with great success making metric threads. I believe I saw a
way to use the threading dial on you tube but never tried it. Something about using the same mark on the dial I believe but don't hold me to it.
