Tim, when I posted this link before, in 2002, there was some speculation
that a tap this size could be used to make large valves such as those used
in oil fields.

Nice pictures. Interestingly, their grinder was imported by Shars,
which we just discussed here.

That seems right Bill, on one of the photos "copes vulcan valve" can be seen
etched into the tap.

I'll stick with small hand taps thanks!

I notice that everyone who is shown working on it where you can
tell seems to be old enough for gray hair.

I wonder whether there are younger people working there, or
whether the entire skill of the company is in old farts like most of us?

Enjoy,

also interesting - I always figured you would first turn threads, then cut
flutes, then harden, but clearly that is not the way it's done - cut flutes
and heat treat, then cut threads

Somewhat unrelated, but my guess is that it is for a pipe inside a
pipe type of situation, maybe a huge heat exchanger.

well, if "I" had to guess, I'd say it is used on a christmas tree
(http://en.wikipedia.org/wiki/Christmas_tree_(oil_well)) but I'm not an
expert on oil field technology
