I HAVE THE STUCK IN SEAT POST FROM HELL. HELPPPPPPPPPPP.
stidds:
Is it a valuable frame Dave?
If not this is what it did to Jo's mid-school Redline when the seatpost wouldn't come out no matter what I soaked it in.
1) Drilled a hole through the seatpost that was visable.
2) Find a ballbearing that fits inside the seatpost and put it in.
3) Put a strong bolt through the hole I drilled in the post.
4) Turn frame upside down.
5) Drill a small hole in the underneath of the bottom bracket.
6) Put a metal bar though the hole in the BB and up-through the frame and into the seatpost which then rested against the ball bearing.
7) Hit the fook out of the bar.
Drastic I know, but it worked when all else failed.

it's a nightmare dave. got 3 myself at the moment. an alloy that's welded itself in. that's being melted out at the moment with caustic, one cro-mo and the fecker has snapped just at the top of the seat tube using the vice and frame turn method, heat didn't help before that. it's gonna be a carefull sawing job. one i haven't tried yet, 2 nighmares at once is enough :LolLolLolLol:
just keep at it dave, before this one, the vice and turn the frame method has always worked for me, good idea is to find something to put inside the top of the post so you don't crush it too much and cause it to split. good luck. ;)

Hi all
I hope this helps.
I said this years ago, but as before - really stuck metal is broken by freezing.

I worked with the Environmnet Agency for a while and the engineers used to freeze lock motors / guillotines and other outside large machinery when replacing stuck and corroded metal parts.
