Seatpost 1 - 10mm axle, me + hammer 0
bigsman:
Fook me I'm gubbed...just spent the morning knocking seven shades of you know what out of the 'seatpost' I mentioned here - http://www.radbmx.co.uk/forum/index.php'topic=90480.0
I know the stuck seatpost thing has been asked a fair few times but this ones a wee bit different because the post isn't a seatpost and its got a steel outer and alloy centre. I've drilled it through and put a 10mm axle into it, wd40d it from last night to today then spent the morning with my biggest persuader battering it and no movement at all :'(. Next I put some heat on it and then same routine but no dice. The axle now looks like a piece of macaroni so I'm looking for something stronger for phase 2.
Can anyone suggest anything that the home DIYer might be able to do before I give up and take it into a shop?
Cheers

have you tried costic soda , it will eat the alloy post away then just remove the metal bit..bung up any holes in the frame as best you can then apply costic
as long as the frames steel

the above sounds good, then seal b+b and fill up with diesel, this is supposed to do the biz :daumenhoch:

Aye cheers guys caustic is on the list of possibles but it is quite extreme and is gonna mean the garden becomes a kid/dog exclusion zone! Reading up I take it that the caustic won't touch the steel? So in theory I'll be left with just the steel outer post and the middle will disolve away....thinking this could be my next step. I've resisted the urge to lop off the visible bit of pipe cos I thought it would always be more likely I'd need to use it for some of these other ways of tackling it but as I try them and crash and burn I'm thinking about cutting the post down to the min before I try the caustic approach. Cheers for the ideas - keep em coming :daumenhoch:

it wont touch the steel, BUT do not inhale the fumes bad bad bad.
