Hi Folks,
I recently got a South Bend 9A lathe. It is a decent old machine with one issue and I thought if anyone here has a 9 perhaps they could help.
On the cross slide behind the handle is the dial with the 0.001" graduations. The dial should have a thumb screw so you can reset to 0. My thumb screw is missing. I tried to turn a 12x32 screw in the hole and the diameter seems to be correct but I can only turn in 1 turn so the thread is not 32tpi. I tried to figure out the tpi with a thread gage and I think it is 30 but it is hard to tell.
So if anyone has an SB 9 and you felt inclined could you get the tpi on the thumb screw for me?
I would definitely appreaciate the help.
