Evening all,
Today I decided that I'd make a couple of thumb screws for my 260 so that I could easily zero my cross-slide and compound dials, replacing the grub screws that are barely long enough - Only problem is I can't determine the thread.
I know the diameter of the stud that fits is 180 thou (4.57mm) and its a 24TPI thread.
The closest Ive got so far is that it could be:
I have a No10 UNC die but that doesn't seem to fit - I turned the shaft down to that of the stud that fits and then ran the die down it.
Could anyone confirm what it actually is?
Thanks
Jon

The closest Ive got so far is that it could be:
- No10 UNC
- 3/16 BSW (But it looks like a 60 degree and not a 55 degree as BSW should be)
