Steering wheel removal secrets

["Chris King" <cbking@alum.rpi.edu>]

Listers,
 
What's the secret to removing a steering wheel? I've tried pulling, and
smacking the column with a hammer, a little PB blaster, more pulling,
more hammering, more hammering while pulling, and the thing refuses to
budge. What have I missed? Or am I gong to need to spend a month at the
gym first?
 
It's a '79 four spoke wheel, if that makes any difference.
