Folks,


Emergency call from a friend that has a bit of metal corrosion between
the stem and frame of a bike - It's well and truely immovably stuck :-)


Things tried include Heat, Coke & WD-40. Not tried is an Angle Grinder,
Plusgas or Tomato Ketchup.


Any ideas?


I recently had a sheared off bolt on the ally SD1 engine. Only thing that
did shift it was welding on a nut so the remains of the thread got cherry
red with the heat. It then came out easily. So heat does work - but you'll
need a lot of it. Likely so much you'd damage any paint finish. Otherwise
it will be down to drilling it out.
