So, what's a good approach to getting it unstuck?Â* I've drilled out
most of the grub screw that should be holding it, I doubt that's the

The coefficient of thermal expansion of Aluminium is about twice that of
steel, so I'd try heating it.Â* Aluminium conducts much better too.

Hot oil might do it.
