Another stuck seatpost thread...
Well it happened to me finally, I have a very stuck/rusted in seatpost the only upside is it's steel, and in a steel frame. So here's the deal, it's probably 5 inches over the seat lug, the built in seat clamp came off in my attempts to remove it, the top is developing a crack down what I assume is the posts actual seam which is why I am apprehensive and here for input before I go to "interesting" methods, I've tried PB blaster soaking it and "breaking" it with a hammer/small chunk of wood at the top.. I don't want to resort to a torch or soldering iron for heat since I like the paint on this bike, I have heard of using a hair dryer is this worth trying? And no I have not thrown it on the vice yet I'd like to break of the rust bond up if possible before being forced to do that as I value this frame...

and putting the frame in a dumpster with the seat post in place.

I think the OP means the seam of the seatpost which I find odd, especially coupled with a steel seatpost having an integral clamp
I think we need some pics

Correct seatpost not tube sorry if I mistyped, threw it on the vice and I messed it up royally... the seam folded and then broke then caved in quite a bit, making 2 flattish sides which still didn't help getting the damn thing to turn! Can't take pics right this second but am getting frustrated.

I have the same problem and I've never found a way to take it out although I tried my best. I'm still with the seatpost stuck in the frame. I think the case is hopeless

I'm not easily discouraged, still plucking away at it.

1. PB Blaster is mediocre at best for this job. Need to move up to Kroil, Acetone/ATF mix, and so on.
2. Whatever you soak it with, it needs time. Let it soak and sit, then soak it again, maybe a day total.
3. Assume you are going to destroy the saddle, you need a large vise, and a secure workbench.

So I've decided to get back to the MB-4, I've been doing my best to preserve the paint so I think I'm going to devote a half hour a day with a hacksaw blade until the damn seatpost comes out of the tube! I've been looking through other methods in vein, and I've tried soaking it for over a week with little result.
