Doing some experimenting, I tried the following numbers on the threading dial.
1 - cuts overlapping threads.
2 - see 1.
3 - see 1. (this is the number I used when I cut the practice 10TPI acme thread)
5 - see 1.
Leaving half nuts engaged - see 1.
Clearly there has to be a gearing issue. I'm taking a break from this and then I'll go over all of the gears and levers once again for the umpteenth time.

P.S. By the way, the so called manual that came with the lathe is a far cry from being a manual. It has no content on operating the lathe and does not even include the chart shown on the front of the threading dial mechanism.
