It appears that the drawbar is too long and that means that when the
collets are threaded they can not be drawn up since the tabs are not
close enought to engage the flange because the drawbar is bottoming out.

So it sounds like if you inked the collet threads, you would see that
the drawbar female threads are completely engaged - that the end of
drawbar is hitting the thread relief edge on the collet.

If this is the correct collet setup for this lathe, what happened
that 'stretched' the drawbar? Or is this a retrofit, or a closer
off of a different machine?

One way to make this work would be to face off the end of the
drawbar, and cut the threads deeper in it. It's a bit tough
picking up fine ID threads like that, but it can be done.
