Need some ACME tap help.
As mentioned before I have to replace my cross slide nut. My screw major diameter (OD) measures @ .441" and the Minor (ID) is .336" The old nut Minor ID measures @ .341"
I believe and a quick search seams to confirm that ACME is measured on the Major diameter so I figured I had a Left Hand 1/2-10 screw.
Got a 1/2-10 left hand tap today and it is bigger than my screw and will not thread into the old nut. It Major measures .526" and the minor about .417".
What am I missing?
