I agree that slicing the nut and stud off would "Git 'er done"
quickly.

I really like Jim Wilkins' idea of drilling
axial holes in the nut to weaken it then attack
it with the Mototool. That gives me a couple sections
of nut and an intact stud so I can satisfy my morbid
curiosity about why the fastener failed so miserably
under "weak old man" torque.
