I like the freezer idea, has this ever worked for anyone on here?
You can buy a aerosol that contains some kind of freezing agent, for use by plumbers. I've seen someone use that to remove a stuck seatpost by warming the seat tube then spraying the seat post with it, and the subsequent contraction releasing the post.
