"One must be patient" re: stem and seatpost removal.

Sorry, but I'm not patient. Most methods don't work because the vise being used is TOO WIMPY!!!

Yeah, I do dribble in some penetrating fluid from both ends and let the job sit overnight if I can. Eventually I clamp the seatpost in my bench vise attached to a very heavy weld table, grab the frame by the head tube and rear dropouts, and twist while pulling up. There is always some give and this is what you have to develop and work on. If the seat tube gets hot, and it will, sometimes after just a few twists, go away and work on something else for a while until it cools off. Repeat and repeat until the seatpost comes out.>

I second this. I also use AeroKroil http://www.kanolabs.com/ to remove frozen parts. For seatposts that have been cut off or broken, I use a dremel tool or a sawzall to slot the post and then I remove it manually. I know that these methods may sound like drastic measures but when you are working an event on the road, time is of the essence. I attach a 6" Wilton vise to a 2" receiver mount that is welded to the side of my work truck. There is nothing like a 20000# anchor to work with.

For frozen stems I spray the stem, let it soak for a few minutes and then use a 5/16" steel rod to drive the stem out from the bottom. No muss no fuss.
