Hi Charles. Nothing in life is 100% accurate. Tolerances, limits and fits appear everywhere – see my opening sentence.

He is repairing an old pencil sharpener, not a micrometer, although even many of those have adjustable nuts !

My point was that it is possible to make the threads needed. Another job I did was for an adaptor for a digital camera, 40mm ID x 0.75mm pitch.

Needed to be more accurate and this was accomplished.

However, that is not actually cutting the odd thread.? It is just cutting something close enough to be "good enough".? While t is a valid solution in many or most cases, it is not actually cutting the correct thread.
