Guys I am going nuts. I have been trying to cut threads on my SB9a, and the pitch always comes out wonky.
In this instance, I am trying for 14 TPI but when I do a scratch pass, it doesn't fit the gage. At 7 threads its off about half a thread already and measuring it puts it at 14.5 to 15 TPI. I don't know how I could set up for this if I wanted to.
The odd thing to me is that its off but close so there isn't a gross error somewhere like I put on the 40 tooth instead of the 20 tooth stud. I have the levers in A-8.
Where do you think I should examine next?
