Removing stuck or seized seatpost?

Cheers. Unless I am a success tonight, see you in the morning.

Tommy, thanks for the offer.

tried the vice, but the cut post plus chemicals ended up with the post breaking off like a stale crisp. i asked one of the techs and he suggested heating the seat tube, but you'll lose the paint job. just let me know if you want me to do it. text me if you get this in time.

Need the post out for a paint job, so try what you think? Reading this post earlier - think it needs cold to shrink the alloy as alloy expands quicker than steel?
Don't mind paint damage at all. Cheers

This is crazy stuff. It's like an operation.

It is indeed!!! Think it'll be on Casualty next weekend!!!!

let's hope the bike is on Casualty and not me. i'll give it a go and see what i can do.

Watch yer fingers... One day, I'll look back on this and laugh!!

ok. just attacked it with a brazing torch and the aluminium is too soft to get a proper grip on it. even tried a t-shaped reamer that wouldn't grab onto anything. the only thing that i can suggest now is to either get it drilled out or to take whatever is left of the sawn off seatpost and push it down into the tube so that you can at least get enough seatpost into the seat tube to have a working bike.

well...gave it a go...and was beaten.

Ha ha ha... Oh well, thanks for giving it a go!

Might be worth leaving the chemicals in over the weekend, really want it out if possible? And it was going so well - famous last words eh?

What time you around to?

i'll be around here until about five or so. the building shuts at six.

Yeah, should be able to get over before then.

shoot me a text when you get there.

Now your on the last ditch atempt of cutting it out. Good luck!

slowly slowly, catchy monkey!

It's out it's out out out out!!! It met it's day of reckoning yesterday, dropped off at Armortex this morning!

congrats! did you get it out by sawing or did the chemical finally do the trick?

The drama has endeth. What on earth did it take? (I can't imagine what it finally took to get that sucker out.)

2 days soaking in Caustic Soda - it was then thin enough to cut with a blade about an inch down, then used a hammer and 2 different screwdrivers to chisel it until I had a 5-10mm channel that allowed me to use brute force to separate it from the frame. Then used needle nose pliers to wiggle it out! It was a great moment!

i bet the whole process ended with a massive "nuuuuuurrrggggghhhhhha".

glad you got the post out.

Something like that... I have a pic, but no photosite to link to, it's on my drive?

i am so glad.

this post has been like an epic norse saga.

I think you should make some kind of sculpture out of whatever remains of the seatpost. Whenever life seems a bit crap, you can look at it and remember that adversity can always be over come, eventually.

Or maybe you should strap loads of explosives to it and make a massive, cathartic explosion :-)

Hey, I have a stuck seatpost on my (other) bike, maybe now you've got yours out you could come round and sort mine for me... I always like to go to the experts ;)

let's all go, bring the tools, dynamite, corrosive acid, tower crane, forklift, diamond-headed drills and sleeping bags.

Ha ha ha ha.... yeah, i'm gonna use it as fall back if my current profession fails!
I spent 18 months restoring a 1967 Lambretta, so a pesky seat post was a walk in the park!
Sometimes... you have to be patient, and sometimes.......... you gotta use a big hammer!
