Re: Broken stud extractor; now what?

[Keith Simpson <ksimp@cgrams.com>]

I used to use extractors - Now I use lots of heat before I do
anything - propane works fine, MAPP is better - if I had
oxy-acetylene I might use that - but that might be too hot - I
would next go to right hand drill bits - I know people that have
had great luck with them - sometimes hard to find.  What I have
done when they are flush broken (I don't have right hand bitss)
is carefully drill out with just the right size drill and then
tap out the old threads.  My heart goes out to you - this used to
happen to me alot in my younger days - now I go the the propane
torch whenever in doubt.  Good luck.
