I just received a die holder to use on my mini-lathe tailstock. I was
surprised to find it was only 1 piece - sort of a "t" outline, with a
1" recess for the die at the big end and a hollow shaft at the other.
I was expecting something with 2 pieces that slid as the die cut the
threads. Am I missing a piece? Should I make an "arbour" to go into
the tailstock that the holder can slide on? Is this a die holder for
something other than a lathe tailstock?

Thanks,
Chris

Mount it in a tailstock chuck, and leave the tailstock unlocked.

Mine has an MT taper, same deal less the drill chuck

Chris,

From your description it does sound like you're missing the arbor that
fits in the tailstock and the die holder slides on. Have you contacted
the vendor for clarification of what should be there. Do you have a link
to the item you bought.

I think what he has is

The sliding type is like this

(I suggest a set screw below the surface to retain the die to
avoid injury when the holder spins.)

If you like the sliding type, you can make a sleeve with a 1/2
diameter hole to slide along the guide and then just clamp your
existing holder in one end of the sleeve. Not as "shoppy" as a
custom piece that you knurled, but a lot quicker.

can't make a link for some reason. "http://www.kbctools.com/can/
main.cfm" gets close, then you need to go to page 129. It's KBC
part# 1-528-004.

I think I can make it work using the suggests made. I'll make an
arbour for it some time when I get a round tuit.

Hey, this thing works pretty well! I was a bit concerned about the
tailstock clanking once it was loosened to slide easily, but it didn't
seem to affect the results too much. Might chuck the holder in the
headstock and skim the "socket" for the die - it looks like it might
be a bit uneven.

Don't know if I'd want to make any big threads, but it does a better
job on small stock (1/4") than I can by hand in the vise.

The cheap solution under 1/2" or so is to chuck the workpiece in the Jacobs
chuck on the drill press and clamp the die in the drill press vice. Works
like a charm.
