Gunner, I think that mine has a BS #9 taper.

On top of the spindle, there is a square head, I think for tightening
the collets. First, is that right, and second, is that just a threaded
rod to pull the collet or something more sophisticated? The square
head turns half a turn and then it does not want to turn. All I have
is just about 180 degrees of turn.
