Fool-Proof Way To Remove Bolts That Break Off Flush
Ronald J. Fitzgerald, Seely's Bay, Ont.: Ronald's come up with a fool-proof way to remove bolts that break off flush, such as broken bolts in engine blocks.
  "I take a nut the same size as the broken bolt and hold it over the bolt with a pliers. Then I take my MIG welder and weld the hole in the nut full, heating the nut red hot. When you're finished, just as the color's going out of the nut, take a wrench and turn out the bolt by the nut. It'll work every time, guaranteed.
  "In cases where you're concerned the weld will stick to the surface around the broken bolt, first place a brass or copper washer over the broken bolt end and apply a wee bit of weld to build it up. Then use the same procedure described above.
  "I've removed broken bolts this way ever since I got my first MIG welder years ago. It's never failed."
