What's causing this squeak?

Coopman, you are 100% correct about this. It was always amazing what a Morse taper could hold. I recalll clearly using a 6" drill bit in a vertical drill press... no problem holding it with a Morse.
One thing I'd like to add - the mating surfaces should be SMOOTH. Any marks remaining from polishing compound, etc. lessen the grip.

I wondered about that. Probably should have followed up with the fine grade compound. We'll see how it goes.
