Sorry again, I was should have said hard tapping, not thread milling. My
mistake. I was also thinking in terms of what one could do with a CNC
lathe for threading. I have never done either with a CNC, but that doesn't
mean that I won't try sometime. It would involve setting up an encoder on
the spindle and having the appropriate software.

Thanks,
