Well we all now know the out come of Mikes dilemma. Most of us have been in
a similar situation.
The last time I broke an extractor in a bolt this is what I did. A little
micro surgery. I fired up my trusty Gibbonizer (that's a Dremel Moto Tool
or its equivalent). I used a very small diamond bit, I get these from my
dentist friend. Then I just removed bolt material around the broken
extractor. Eventually the extractor came out. Once the extractor was out,
the bolt was virtually hollow, I "crushed" the bolt and used needle nose
pliers to remove it.
As a result of this experience, I now drill broken bolts with the largest
drill I can, without messing up the threads. This works best if the item
can be placed in a drill press and the hole must be centered.
