Acme & metric trapezoidal threads can be the trickiest to do because of the included angle being 1/2 that of a standard 60º thread.
When making them I find that there's a VERY fine line between "the gauge doesn't quite go though the nut" and "clink clink" looseness. Usually, that difference is nothing more than that last "spring pass."
Good job Ed!
