Watanabe thread size?

[John Formsma]

Hey...you mean there's a chance I could get paid for being anal
retentive??  Cool. <G>

It's that I don't know much about machining and how much might make
what difference.

OK, yes, maybe I'm being a bit too concerned.  Maybe. <g>  Just so
you'll know, I had already ordered a die for a Watanabe tip before I
asked the question on the list.  Just wanting to make sure I was
getting the right one.

Oh, I did some calculations, and it's definitely over 10º.

P.S.  Who can pass up a time like this for an engineer joke?

Q.  What do engineers use for birth control?

A.  Their personalities.
