How would you measure the angle of the thread?

Only two ways I can think of. One, an optical comparator is the quickest and likely most accurate. I don't have one of those either. Yet.

Other than that, grind a HSS tool at 29º and one at 30º and see which fits better?

If you send me both parts I can make a nut to fit the otherwise good screw.

Or, take this opportunity to fit a ballscrew? Or is that "as casting pearls before swine"?
