Rant: A seized seatpost on a vintage steel frame ate my whole afternoon
It was a 1985 Miyata with an aluminum post, and the corrosion lock took over 4 hours of heat, penetrating oil, and careful twisting to finally break free. Anyone have a better method for these old bonded posts that doesn't risk the frame?

Man, that sounds like a brutal day. Had a stuck post on an old Peugeot that fought me for hours. What finally got it moving was a ton of liquid wrench left to soak overnight, then clamping the post in a big bench vise and carefully turning the whole frame. The extra leverage from the vise was the key, but you have to be super gentle to not tweak the frame tubes.

Clamping the post in a vise and turning the whole frame is a bold move. I'd be really worried about putting that much twist force into the seat tube, even if you're gentle. It can ovalize the tube or damage the braze-ons. I've had better luck using a long pipe wrench on the seatpost itself, after a good soak, so the force stays on the part you're trying to remove.

Tbh my vise skills are a safety hazard.
