While flicking through the Axminster catalogue the other day (looking
for an elusive long 7mm SDS drill bit!) I noticed that they had a range
of drill bits with morse taper shanks designed to be inserted directly
into the quill of a pillar drill.

This started the train of thought - What is the "proper" way go about
removing something (i.e. the chuck for starters) from a morse taper
interference fit?

A taper separation tool. For some tool fittings that is a tapered wedge that
fits through a slot at the back of the female taper and bears on the back
end of the male taper. If you don't have that slot, it is a pair of folding
wedges with a slot in them to clear the neck of the taper.
