I'm currently dealing with the same problem. I've gone through the various l ubricants and the Kroil stage, and am finally considering simply cutting the post off then cutting it internally in two places, the length of the post, to remove it in pieces. 

A framebuilder friend has suggested using a torch with enough heat to melt t he aluminum post, since it will melt before the steel frame. Seems like a ra dical solution. I have some reservations about it, especially since that hea t will be near the very nice seat tube cluster and might weaken the brazed j oint.

If there's a better method, I'd really love to hear of it.

OK, time for the semi annual stuck seatpost thread.

Received a 70's Trusty-era Viscount today. The setpost is stuck, which ha d caused the seller to remove the saddle but leave the seatpost exposed, which

punched a hole in the box. The saddle is a nasty cheap steel and rubber Messinger and the post is a cheap aluminum straight post, so I dont care if I destroy both of them getting the post out. Reinstalled the saddle to use as

lever to try to move the post, no luck so far.

So any new magic formulas besides Coca-Cola, Ammonia, Kroil? I could cut off the post at the seat clamp, but that might just make it harder to get the remaining part out. Does the fact the straight post is aluminum, and theref ore soft, make it any easier to get it out? Any new suggestions or reposts of o ld ones?

Good news, I guess, is I only pait $86 for this, although the shipping was

almost as much. And it has a good set of wheels, Titlist deraillers and shifters and Viscount bars, stem, pedals and brakes, which probably is worth the $86, but the frame could be an interesting rider if I can get the damn post out.
