I have seen recommended this technique:
1: Find a washer with a hole a bit smaller then the bolt.
2: TIG weld it to the stump (through the hole).
3: Weld a nut to the washer.
4: Unscrew it with the net.
Unfortunately this assumes you have a TIG welder and you know how to use it...
If you do a lousy welding job you may just end up welding the stump to the
block!
