Cheers man I'll be taking extreme precautions if I attempt it don't worry!  Think I've got a tub of crystals do I make a solution in what? a plastic tub! or glass bowl ?
and then what do you reckon...drill down into the tube a bit to make a reservoir and just slowly add solution and let it do its stuff?

I'm worried just thinking about it  :LolLolLolLol:

Ok things have moved on...I've cut the mofo and the seatpost aint solid after all....



Some edjit has put their butt plug in the end of a normal seatpost...exhibit a:



and exhibit b - no further questions your honour...



So...that now rules out the caustic soda route and puts me back into 'normal' stuck seatpost territory.  Hasn't helped me get the thing out yet though.  I'm now trying to saw down the inside of the post with a hacksaw blade...it should work but christ it's hard going for precious little sign of anything happening.

Takes it out yeh this resto / salvage fun!

mate ive had a simalar problem with a post stuck in my dyno frame and ended up cutting the post down and cutting down the middle of the post at the back and pushing either side into the middle but still the fooker wont cum out i think its well seized in there so i guess i will have to try the diesel treatment my only hope now is that my cousin thinks he can do it and as he managed to get a stuck stem out of my mtb forks before i guess im gona let him try and hope he manages to do it good luck tho mate :daumenhoch: hope u get it out  ;)

I had a problem like this the other day. I ended up clamping the vice to the seat post (in mid air - and my vice is heavy duty!!) , tightening it up as much as i could and then I got my old man to move the post left and right as i sat on the top tube (bike was built). Took us half an hour using wd40 and twisting the vice left to right and pulling the vice upwards as we twisted. Post was fooked obviously afterwards.

Was sweating like a Muslim at customs but it worked. :daumenhoch:

fit another solid bar in the post, weld it with a arc on full to heat it right up, then while its hot stick it in a vice, the seatpost wont collapse like they do when they are hollow. soaking it with liquid wrench ( marketed as PLUSGAS) for a few days beforehand helps too. Also diesel has a similar effect.
