man, is that a giant PITA!)

I'm willing to bet that they are really metric screws (4.25mm pitch
(0.1673"
per turn, instead of 0.1667"/turn)). Of course, neither is very useful,
but the 4.25mm might be better with metric dials. :-)

No, surprisingly, they're actually 6 TPI - and the hand wheels go up to .166
... with a bit of extra space after the last division. Yech!

O.K. I've seen ones which were marked for 0.125" (with a little
extra unmarked space) for a full turn, but which were in reality 3.25mm
pitch (0.127953"). Really a crazy one, and a pain to use.

I would like it -- but I'm on the wrong side of the country.

I guess I'll be holding on to it. I'll justify it by saying that if I do
some little production run I can leave tooling set up on it.

Good!

And even if I were local to you, I would feel guilty taking something
out of the family. The only power tool which I got from my father was a
6" grinder -- which he got in trade for an anchor. However, *I* got use
out of it as a kid and later.

Some kids are tool users, and some aren't, I guess.

Yep. I've been as long as I remember. I moved back to my
parent's house after going part-way though high school in South Texas,
with a step-grandfather who was a tool user. When I got home, and
started looking for a hammer to do something simple, I found two -- both
tiny claw hammers with one or both claws broken off. That Christmas, I
got him a *good* claw hammer -- which I still have.

I also talked him into some other power tools for maintenance on
his all wood sailboat.

Enjoy,
DoN.
