Pmed you with regards to the chuck

Coomber; that was the plan but after weeks of trying with caustic soda its still not shifting enough of the aluminium to free it.

I didnt try it, not to sure about the frame builder. if not , I shall definitley give it a go when I get it home! I take it you can get it from any plumbers merchants?

they have tried cutting slits down it and peeling it away and it just wont budge. I will have it back at the end of the week and post some photos. The caustic doesnt touch the titanium but it has dissolved most of the aluminium shim (which taken several weeks to achieve).

Aye. I tried it before passing it on to the frame builder, and then he give it a go with both caustic soda and some other type of acidic dissolvent with not much joy. it goes; ti seat-tube bonded to alumimium shim bonded to ti seat post.

Cheers. sounds like he might be the chap for the job!

okay. And what would be your process for removing the remains of the offending seatpost?

Unfortunatley it wont shift down at all either. its fully bonded itself in there. the clamp will work just the same, the seat tube that is in there will have a slit cut in to it to match the seat tube split so the part of existing seat tube will hopefully work just the same as a shim would...

So. My old Sunn exact ti has a seatpost stuck in the frame. Has anyone ever had a seatpost thats stuck (chopped off to the top of the seat tube) and then used a smaller daimeter seatpost inside it as though the remains of the old aseatpost is a shim? please refer to this thread for my attempts...

Update! The frame builder has slowly been working away at it. Now the frame has killed two quality reaming tools and damaged the machine as well, this is some tough as f*ck titanium!! There is a possibility to use the stuck part remaining inside the seat tube as a shim and he thinks we could fit...

REDUCED T0 £220 FR A QUICK SALE. ABS0LUTE BARGAIN!!

Intense 5.5 evp medium in red. Comes with a pushed rp23 shock and newer shock block. The frame has been de-stickerd and has the odd scratch/chip or two but could be easily t-cutted up to look great. can be built up fast and light or burly and awesome. Plan was to raw the frame and build it back...

Re: 18" Sunn Revolt GP frame Fuji SL tubing - £35 + postage Pretty interested in this but just a bit worries it might be too small in the top tube. 18" is sweet for me in the seat tube but might be a bit short (im 6ft 1 ish). Is it 22"" ett? Let me check it against my old chameleon

Re: Cove handjob XC 17.5", Surly ogre forks. Splitage! whats the ett on the frame?

Re: I would be interested in the dx hub if its the back and red one? and if it can be easily converetd back to 110 old as this would be perfect for my sunn bmix build! (I dont suppose you have the front hub too?) Cheers

This has been dicussed as a (very) last option with the frame builder, but i think its drawing close to that stage! Eeek...

I will swap for a 90mm. At leat I think its 90mm (might be 100mm), I can check tommorow for you . Cheers

Re: For trade or sell: Mk1 Santa Cruz Chameleon frame Too small for me im afraid, would have loved another one too. They are amazing bikes built up, i would just keep it!

Re: Tasty. Ive still got a green mk1 lizard, ace bike! Whats the measurement from centre of the bottom bracket to the top of the seat-tube? I would love another to have as a single speed rigid. I will have a div around and see what i have to swap, unfortunatley just sold a load of parts at the...

Re: I should have probably left it over night as you say, 2 hours wasnt long enough. Im not sure why chopping the seatpost and pouring it in from the bottom bracket would have been any better other than completley losing the seatpost? It is the shim that is causing the problem and there is a...
