I really thought I'd beaten this seatpost.
When I wedge the post in the storm drain on the road and twist the frame (don't have a vice) it now turns.
I really thought that when 'I broke the seal' I would be on the home straight, but I still can't remove the post from the frame-set. Tried belting it upwards with a heavy hammer using the clamp area. I'm getting a solid contact but it just won't budge.
@lynx it's a steel frameset, alloy post.
MrBaklava-
the only way is to wind it out while pulling. whacking it with a hammer won't work.

A vice and a heavy bench will really help. You need to encourage the frame away from the seatpost, rather than just twisting. Seatpost in vice, shoulder inside the frame, twist and stand up

PDry ice works. Especially as some people get food delivered in dry ice. Ally contracts more than steel when cold.

If t
Frame is steel and post is alloy then wrong or no grease. Water has got it and caused corrosion. Ally and steel corrode then expand.
