Vice/seatpost help in E9?

So i have a pretty stuck seatpost... coca-cola didn't budge it, plusgas didn't budge it, ragging on the saddle didn't budge it and a locking wrench ended with an ever-so slightly strained right arm, and what seems to be a deformed seatpost. The next option seems to be sticking it in a vice and getting more leverage from the frame.

Anyone in the E9/hackney area have the means to assist? LBS will probs charge up and above £15 to even look at it, so thats at least 13.5 polish beers up for grabs...

I'm in E11 but will be over in E9 in a day or so.
What materials are we looking at, frame and post?
Are you wanting to preserve the frame's paint around the seat tube?
I'll take this on... unless it's carbon.

Not carbon no... Steel frame + alloy seatpost. I've a feeling its a mix between rusty and old, and a 27.2 seatpost in a 27 frame. Either way its in there fast.
I'd quite like to save the paint if i can, but it might have to be torched out... Drop me a pm about how we can go about this... Ta!

I hope you get this mail before another trashed frame ends up on ebay!!! Its usually quite easy to get a stuck seat post out, it just takes a little time and patience and you don't need to bash anything or burn anything or wreck the frame in any way whatsover. I've done several over the last few years without damaging any tubes or paint.

Hacksaw the seat post off leaving about 30mm of post exposed. Find a nice new hack saw blade ideally you need a handle that holds on to one end but gripping with fingers works too, its just a bit tiring . Start gently sawing vertically down the inside of the seat post parallel to the seat tube - not at an angle. It takes time but you don't really need to worry about cutting the steel seat tube as you've only got a light grip and you're only able to apply enough pressure to cut the soft alloy of the seat post.
Once you've gone through at the front cut a similar slot at the back then crush the seat post halves together in a vice or with mole grips and pull the 2 halves out.

Sorry if the explanation is a bit vague, I think there may be better instructions around on the web.

Of course where you read about cutting or crushing allow seat tubes I mean seat post!!!

Dont worry Gordon, im not in the business of ruining a frame due to a rushed job. My concern is the tubing is pretty thin, so dont want to damage it via sawing... thats why im avoiding that route currently. The next option is freezing the seatpost with one of those dust sprayer things. The plusgas got rid of the rust by the looks of it, but im pretty convinced its just a super-tight fit via wrong seatpost.

Thanks for the concern though!

I won't be damaging anyone's frame. I'm a mechanical engineer with 30 years of experience doing "this sort of thing".

I won't be doing that ^^^^ jail break method, my hands are far too delicate.

Ok I won't panic. I've used this method on Condor 853 ProTeam frame - very thin tube, and a Cougar SLX frame - again very thin, without a mark on the steel. As I say, its just a light touch you use and you go slowly through the aluminium seat tube but it simply doesn't have enough force to touch the steel. I've been pretty cautious each time I've done it but pleasantly surprised by the results.

Just seen another trashed frame on the 'bay. Makes me really sad to see lovely steel frames ruined by clumsy folk with club hammers and angle grinders!
Best of luck with sorting this one, sounds like you've got it well under control.

Cheers Gordon, an yeah hawkes is going to give it a go. The frame is an 80's Aende, so i definitely dont want to be damaging her.

waltham forest bike recycling centre have an open workshop on a saturday morning, they have a pretty solid vice with decent teeth that hasn't been fazed by anything they've shown it
if all else fails they will assist you for a donation to the workshop

Progress... it moved! slightly. pretty much filled the seat tube with plus gas and left it for a few days, then big stick through saddle rails. I only got it from the 'a' of campAgnolo to the 'n', but its a start. thanks for the suggestions!
