Hi Larry,
Threading 101:
The idea of 29 degrees is half the thread angle (usually 60 deg)
less a smidge. People never seem to express it that way but once you
understand what's happening it's obvious - and equally obvious how
it needs to be modified for a 55 degree Whitworth thread, etc.
Thanks guys! This has been an excellent thread (ahem) for a beginner like
me. The only thing I can't see with this technique is how to accurately set
my cross-slide to 29degs.
