I recently bought a Jacobs chuck and a Morse Taper for my lathe. I think
I'm missing a step somewhere. When I mount it in the tailstock, it just

for.

I can make it drill by holding it still with one hand, but that doesn't
strike me as particularly safe, and it's certainly not comfortable.

What part of this am I missing?

My guess with the current info would be either the wrong size Morse taper for
your lathe (#1 #2?) or a dirty taper on your tail stock..

With a proper size and good fit, the chuck should only spin in the taper
(ass-u-me-ing that's what's spinning) if you bind the drill bit or didn't seat
the Morse taper well.. YMWV

Well I grabbed a couple of minutes to mess around with it, and the
likely problem seems to be the grease on the taper. I'll probably get a
chance to mess about with it this weekend, and I'll know more then.

Thanks for all the thought and ideas.
