A spindle, or an arbor? It sounds like you want to turn down an arbor
that originally FIT a morse taper spindle.


i know nothing about a mt spindle google gives all sorts of purchasing
info

i assume the spindle is made of very strong steel and cannot be cut
say with a carbide tool

It probably can be cut with carbide, but it will be hard to do so. You
probably
would do well to anneal it. That can often be done by heating it with a
propane
torch. The smooth ground surface will turn "straw" colored at a certain
point.
Heat it perhaps a little past that point and then let it cool slowly.
This should
reduce the hardness enough to make turning it easier with carbide. You
probably
are not going to be able to turn this on a jeweler's lathe, or at least
it would take
a long time to do so.

In all probability, what you have is a chuck mounted on a removable
morse taper/jacobs taper arbour. Check for manufacturer's information
from the maker of the chuck, then look for a suitable arbour to adapt
to your requirement.
