1.) Grind a flat on the stub end where you have been applying the
Vise-grips.
2.) Carefully center punch the flat.
3.) Using a small drill, start a hole, and point the drill to correct any
remaining centering error.
4.) Drill through the broken stub, using increasingly larger drill bits,
until you have removed most of the stub. Stop when your drill starts to
touch the threads on the turnbuckle body.
5.) Clean out the remaining shreds with a tap.
