Many woodturning accessories (centers, arbors, etc.) have Morse tapers
with solid shafts and no tangs. Recently, in a junior moment, I put
such a center into a MT2 to MT2 extender. The extender has a tang slot,
but the center's taper did not reach it.
I really leaned on the handwheel to secure a heavy blank. Now I own a
dedicated extender with a built in Nova spur center.
So far heat, cold, WD40, pounding, hammer drill, cursing and sweet talk
haven't prevailed against that reluctant taper. I tried a short pin thru
the slot and into the hole to reach the center's tip so as to use a
drift. To get thru the slot the pin had to be so much smaller than the
hole that the drift canted the pin and it wouldn't budge the center.
Moral: when you insert a taper, be sure you have a way of removing it!

Fortiter,

How far below the tang slot is the end of the center?
Could you get a piece of steel the thickness of the slot and
narrow enough to reach the center and then use a steel wedge to
drive out the center? If you could rotate this rectangle of steel
when it's in the center of the extender it wouldn't come out of
the slot when you drive the wedge.

Just a thought
