I'm working on threading for the first time and am having trouble getting the correct threads per inch. My lathe is a 10k and is missing the gearbox threading plate. I received a picture of one that says B and third one over for 20 tpi. I'm getting more than 36 per inch. I checked the stud gear which I think is the small hear attached to bottom of reversing bracket and it has 20 teeth. Please help if you can. Thanks!
