sawzall:
you could always drill out seat post if all else fails, i did one for darren on a rickman took about three hours  :santa_cry: post was made of a crumbly steel when i put it in the vice and twisted it it just tore so i had no option but to drill it!

Peanut:
ok, I tried everything, heated it up, cooled it down, kicked it, wacked it with a big bit of wood, stuck the seat between two brick walls and tried to rotate the frame, wacked it some more, soaked it in everything from the shed, hit it again, soaked it in everything from the kitchen, heated it up again and nearly set fire to myself and the garden.

While going to sleep I thought of one thing I haven't tried, placing a piece of wood on the top tube and bracing a car jack between the tube and the saddle.  :santa_angry:

oberonspacefruit:
good luck with that method

weld an enormous nut on the end of it.

ORB:
oh, here is how i did it on that DP Firebird I paid a tenner for.

-Stripped the bike down to just the frame, with the post jammed in.

-Cut the post off about an inch above the sop of the frame.

- Got some various grade hack saw blades (long)

- Sat infront of the telly with a beer and the frame between my legs and started to cut slots out of the inside of the post (takes about 2 hours to cut one slot)

- When i had four slots cut (all oposing each other) I took the frame out side and filled the tube with a VERY strong mix of caustic soda.

- Leave it alone for a few hours till the soda stops fizzing and then tip it out and add some fresh soda and leave it over night.

- Drain out again and rince with boiling water from the kettle.

- Get a drift and see if you can smack one of the quarters away from the other 3, if not, start cutting more slots, go nuts, cut diagnols, and verticles and try to get as many cuts rite through the post as you can.

- Bray with drift and mallet, nothing happening?

- Repeat caustic soda game

- Repeat all above till you can take it out in bits

- ( i had to get needle nose pliars and twist the post in on its self inside the tube and snap bits off), eventually it will all come out.

- When removed, get a stick with some glass paper wrapped round it and sand inside the frame to remove all traces of rustyness

- After refinish, or prior to re-assembly squirt tonnes of spray grease (not WD40, this stuff is the root of a lot of problems) into the tube.

Done.

Easy

:)
