Tools Needed:             You will need the following tools:

      • Center Punch
      • Drill
      • Small Drill Bits
      • Left-Handed drill extractors
      • Mapp Gas Torch

Step-By-Step:             Here's step-by-step instructions on how to get it done:

          • If it is sticking up at all, tig weld a nut onto the end of it. The heat will shock things a bit and help the bolt break free
          • If that option isn't available, do your best to grind end flush
          • Take super-extra-care and use the center punch to get a punch in the exact center (or as close as you can)
          • Drill a tiny pilot hole all of the way through - taking care not to break off this pilot drill bit.
          • Step up through different drill sizes until you come to the one you use for the broken bolt extractor you are using.

          • Grab the torch and heat the holy hell out of it and then try to remove it.
          • Most of the time, the heat will help guarantee success. 

 


Notes:

Most of the time, the heat will help guarantee success. However, when that doesn't work then you need to press ahead an install a TimeSert. How To - Thread Repair
