Plaza Machinery sells new made in USA (That's what Joe told me) threading dials for 120 bucks postage included. Seems like a more suitable choice to me on an old American lathe. Never could figure out why they sell for so much used on ebay?

I've never seen one made in China and it would not be a profitable venture. The ones that come up on E-Bay are from lathe that lost there's. Yes $100,00 is quite pricy but that is what they go for. Keep your eye out, and maybe you will come up on a deal. Cutting threads with out is very risky and like you said 25 passes could get confusing.

Yeah, I guess
the trav-a-dial is kinda
old school, but I've always wondered how they work
no mechanical connection to the bed. I came to trust
because I was doing a lot of shaft work and had
nothing else that
would measure that long. $45 is a lot cheaper than the
if you can even find one. Out of habit I keep looking
out of the
corner of my eye where it would be.
I also _need_ a threading dial. I've been
considering all the
possibilities, from making one to using one from
that isn't quite in such demand as to promote
highway robbery. In
the end I'll probably cough up 100 more tear
stained dollars. You
can thread without one, but some of the workarounds
pretty tedious for 25 passes with certain tpi.
It's not that hard
to screw up the routine as it is.
Even the little 7x14 came with one, but I did have to
buy one for
the craftsman for a princely $20. From the number of
looking for one on the net, you'd think they would
be coming from
china by the container load.

Last winter I rebuilt a 9A UMD (that I
converted to 10K as I
had the tailatock and headstock available)
It is the second SB I rebuild. (I rebuilt
another SB 10K
