Checking My Nuts

I've checked the gearing and levers numerous times and they seem to be correct for 10TPI. I've ruined the first nut so I'm going to chuck up a piece of round scrap and cut an external thread and try to figure out why 10TPI threads are overlapping. Time to call it a day and take a fresh look at it tomorrow.

The chart for my lathe says for 10TPI I can use the numbers 1-8 on the half nut dial. Does that mean I can use any one of them or do I need to pick one and use only that one for the thread? I've always used the one I started with. It makes it a lot slower though waiting for the number to come around again.

I thought this sounded familiar. Not trying to crack wise Ed, but could this possibly be a case of Déjà vu all over again?

My lathe chart says I can use any NUMBERED line as well.
