Hi , in the past ive had success buy securing the frame in a vice (use ply wood in the jaws for frame protection) then use a large hammer and hit the top of the seat post into the frame, just to get the post moving (put a mark on it first to check for movement) . once you get a 2-5mm of movement , put the acutual seat post in the vice ( lengthways in the jaws) then wiggle the frame to see if it frees up. Ive had success like this before but you may lose the seat post as sometimes it gets really squashed, you could put a wooden dowel inside first to stop it crushing .

May be an option in the worst case senario but from a quick search to find the product the description says it unsticks all metals from anything including paint (which worries me about my original paint surface).

I'm still yet to find the time to collar a bag of dry Ice and give that a go.. plenty of it to go around at work just time to do so seems limited as we're busy busy busy coming up to a whole new computer system **eeeeek**
it wont touch your paint

People have an almost laughable faith in penetrating oil to free parts that are chemically bonded together. It doesn't work until you've broken the bond, after which you might be able to get some to penetrate to ease the movement.

That's what I suspect is my problem, hopefully dry Ice is going to help me break it,

That's re-assuring to know. have you had the same problem?

yes quite a few times

i had one cut out by lbs it took them 7 hours and loads of hack saw blades but the frame was worth it , others i have chopped off and then drilled slowly out or reamed out , then a couple of recent purchases came out after removing pinch bolt and gently teasing the seat tube shoulders open and getting some plusgas in there and then with a big pair of stilsons clamped on to the seat post top mount area and some gentle twists and repeat every couple of days and eventually they both came out without damage .

whilst others i have been unable to move at all tried coke and warming tubes up slightly and not moved at all .

I think I need to find time at a later date to really spend a couple of days attacking it. it's fine for now. just a shame the post is not adjustable for the angle of the seat as it's purely a half inch pointing to far forward... that tiny conflict can slow me down a tad! haha

It would be nice to shift the old post without damaging it really as it's an original part! but if I really really cant move it then I'll be cutting the top and sitting a adjustable seat on top so I can angle it the nose down or sit a thinner seat in it's place :smile: You seem to have a nice collection of bikes (on facebook) how many do you own?

I will have to give those a watch later :smile: thanks

thanks at the mo there is 4 working bikes , 3 Work in progress bikes then a tandem and my trusty old Marin Mtb with 5 nice frames in the loft

Just a couple. One of these days I'll have a garden then I'll erect a bike shed and start my collection... hopefully by then I'll be able to afford a real carbon frame racer :smile: You must have a nice stock pile of other parts then too?

why Carbon when there are proper steel bikes , yes there are a few spare parts in there too , but a couple of builds will dent the stock levels

I've always lusted one of those bikes like team sky ride (i know they're WAY out of my budget) but something I can lift with one finger and I can fancy up with racing stickers would do me fine! :smile:
I need to build my collection.. so far I only have my Peugeot and it's original parts. other than the seat (minus the post) everything else is on the bike.. but I will eventually replace pedals, seat and post and a few other little bits and collect spare parts for "just in case" moments :P
