I would just put some loosening oil around the seam and let it seap into the gap over night. Try wiggling around the next day, repeat until it frees up.
out of curiosity, which bike has the issue? is it frozen? left unused? or just general old stuckage?
Thanks Hughie. I've tried that a bit, to no avail. I'll keep going with it. I'm half wondering if my next step is to head up the seat tube and hope it get's hotter faster than the seat post, so it'll expand and I can quickly pull it out.
soak, soak, SOAK! liquid wrench type stuff, or anything like it. if you were to try heating it, you would have to heat the FRAME, not the seatpost, and if you have paint on the frame, well, it's done. the difficult thing about stuck seatposts is the huge amount of surface area for galvanic corrosion to form. there is a chemical bond there now. there were times in the bike shop we'd have to resort to a long monkey wrench; the harder you pull, the tighter it bites, so you'll either snap the post, remove it, or twist the frame out of alignment.

Hey Jerome,
Has it worked for you yet? If so what method did you employ.
