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
spins freely, leading to a less aggressive drilling action than I hoped
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?


Could be your morse taper's too long, your tail stock too dirty, or it
might be something more bizarre, as others have intimated. I'll trust
your good sense and assume Jacobs is the brand of chuck, whether or not it
threads on or seats in its own taper.

I'd clean both taper and socket, make sure the quill is not retracted and
ejecting my taper, and try again. Snug is a tap sometimes.

Hope you haven't messed up the taper with the spinning.

I got a #2 adaptor to hold a Jacobs taper #33 chuck in the tail stock of
my Delta midi lathe but the joker kept turning kinda like you described.
Then I diagnosticated that the adaptor had a "tab" on the end which
prevented the taper from seating all the way in the tailstock recess. After
cutting off the tab, it worked perfectly. So I will echo what has already be
said already and ask you to scrutinize your problem again and if need be
report back to the group. This is really a great place to glean information
and get answers.
