How do you remove a glued in endpin jack on a vintage mandolin?

Howdy,

I was wondering what might be the best way to go about removing a glued in pick up jack from a 1912 Gibson A mandolin?  Drilling it out or using heat are both options, but both scare me a bit!  In case it matters the pickup is a Hot Dot and I am pretty sure it was installed in the 1970's.

Thanks much,

Ryan

StewMac's knob and busing puller might work. I had an oddball guitar with a frozen stud and bushing that was too small for the puller so I cut some washers into Cs, slid them under the head, then slid the box (to the right below) under the washers. Came right out.
