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
