<< < (3/4) > >>

Heres what u need to do- Drill a hole thru the post a few inches up from the frame and put a nut and bolt thru it.Clamp on some mole grips arond the bolt (this will stop them slipping). Get a blow torch and gently heat the frame to expand it. Tap the top of the seat tube with a hammer to crack the joint. Then try and twist the seat tube until it comes out. It can be a right barsterd but dont expect to save the post. If that fails, shout a load of harsh language and hurl the lot across the garden.I find that works....

markyp:
anyone ever thought about  smashing it back in?if there aint much of it still visible above the seat post tube meaning you can defo get another one in then what wont come out may as well be driven right in,or is this a dip shit idea????? :D

Copied this from singlereackworld, which was copies from elsewhere.

Copied from other forum but may be of use to someone in your position.

"Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker.

*Don't forget the April 2007 "Machinist's Workshop" magazine comparison
test.*
**
*They arranged a subjective test of all the popular penetrants with
the control being the torque required to remove the nut from a
"scientifically rusted" environment.*
**

*Penetrating oil ..... Average load*

None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds

*The ATF-Acetone mix was a "home brew" mix of 50% acetone - 50% automatic transmission fluid.*
*Note the "home brew" was better than any commercial product in this one
particular test. Our local machinist group mixed up a batch and we all now
use it with equally good results. Note also that "Liquid Wrench" is about
as good as "Kroil" for about 20% of the price. * "

So maybe some of that but failing the above get seatpost in a bench vice and use frame as leverage.
