£20 at a good frame builder would have done it - there is a mobile guy up north who uses magic to get them out - £75 I think, and never fails!
It's all lies!

Yup. But I was lulled by the sweet words of everyone who's says hacksawing down the post works a treat! I only paid £40 for the bike so I don't want to chuck money at it, but it holds some sentimental memories for me and I'm keen to get it sorted. Looks like I might not have far to go now before I can safely put another post in.
Cool. I'm practically there!

Um, what's going on with your hand? are your fingers really Trumpian orange, and your palm a pale mauve?
(enjoying this thread in semi-mock horror. I would totally sever an artery with a hacksaw, the lost an eye - at least - to lye)
Ha! It's a weird white balance thing -- half my hand lit from the window and half from the fluorescent tube. Weird it's split my hand in two like that though.
I wish you good fortune with removing that last bit of the post. What is the process that causes aluminium posts to get stuck in steel seat tubes?
It's only by reading through some threads on this forum, that I'm reminded or informed of a job that needs to be done every so often on an old bike. My bike is 33 years old with a steel frame and an aluminium seat post and I had never loosened the post since I bought it new. I was much relieved to find that it was still free. Similarly I don't remember greasing the freewheel threads when I temporarily changed, then refitted, the block about 20 years ago. That, too is still easy to unscrew. My bike doesn't get ridden in the rain and when I cycled to work in bad weather, I used my even older gas-pipe bike. My bike's never had a hard life and has always been stored, either in my flat, or now, out in the garage. Is its easy life the reason that I've got away with skipping these maintenance tasks?

Essentially, when water gets between the post and tube, it forms aluminium oxide. This fills the small space between the two and binds them together. It may be that your post has been very well greased all that time, or that you've just been lucky!

No. Grease IS the problem, not the solution. We've written about it here often. Just search for the words "emulsion" and the problem should pop up.

So. Is it out yet?
I got a similar problem.
I have a Giant carbon frame with a siezed aluminium seat post. It fits me but i want to give it to No.1 daughter and i have no idea how to get it out without destroying the frame.
I bought a bottle of ammonia but then wondered about its effect on the carbon and never proceeded.
The frame still hangs from the ceiling of my garage like a anorexic Giant black bat mocking me.

The proper method has been described here. You'll find it somewhere in the archives. Search for something I posted with the words "sardine can" in there and you'll get it.
Don't do the ammonia thing.
Haven't had much time to work in it this week, so not yet. The chiselling is working - it's slow but I'm making progress. I wouldn't advise it though as there are easier solutions.

chiseling is not an option on a plastic frame so i was hoping some chatters had already encoutered and solved my problem and could enlighten me.
anyway good luck and keep us posted.
