Soak it over night in penetrating oil, diesel etc put a solid bar down the middle of the post prevent it crushing then fix a stem/forks to it and give it some.

None of these methods seem to work on aluminium oxide as they do on rusty steel.

I tried the lot, turning in vice, Tw@tting with hammer, WD40, Plusgas, Coca Cola :-[ before I took matters into my own hands.

Heat the seat tube with a paintstripper or gastorch... and try to wrick the seatpost out while its heated... :coolsmiley:
but no overheating...  :daumenhoch:

allys soft.. drill a big hole in it enough for a screwy , insert and twist

You say it's a pivotal post. It isn't one of the types that has a wedge/quill type of bottom, like the bottom of a quill stem?
As some pivotals came like that. If so you will need to screw a threaded rod or bolt into the wedge and belt it down to free the post.

If it is a standard alloy pivotal post which has degraded along with the frame it could be a right bu66er  to remove,
Did you clamp the post in the vice and use the frame as the lever to twist it round?  I would probably go for this option after a bit heat has been applied with a blow torch to the frame seat tube to expand it.  :daumenhoch:
