(His was aluminum)
And use some liquid wrench or penetrating oil as well if you can.
There is another thread that is the same topic and the way TM mentions is the way it was solved.
I think if you can slice the tube as said and keep short of the frame, prying inward the remains to shrink away from the inside of the frame where the seat post is stuck, that is what I think was done.
Anyone know that other post?
