Supergoose Seatpost Problem - A BIG ONE

<< < (6/9) > >>

750Rush:
I've no idea, but it's got to be worth a go. I don't want to keep it as it is because it's so dam heavy!

BENDYCAT ELEVENTEEN:
burner weight  ;D

well hopefully it is as i said - the cut in the top half of the seat post, should mean it had to slip over the metal tube and the metal tube should be hammered into a old bit of renthal post which is welded it's self into the frame - so hopefully it will desolve out and drop  ;)

750Rush:
I put some caustic soda granuels in the post with some boiling water and left it for the night. It hardly took any of the mixture as is seems solid about 1cm down into the frame. It fizzed a bit, but no frothing like in you Bendy's pic. I emptied the few drops this morning as I didn't want my kid to touch it today. I'll have a look when I get home tonight, but I think it might need machining out or something more severe  :'(

I have thought of getting in there with a small drill bit to see if they welded the iron rod in its central position within the frame tube. I thought I could drill small holes around it and try to get some more caustic mixture in underneath and around. If I can get enough drilled holes in there, it may weaken it enough to come out?

If it does come to machining it all out, and then getting it welded, can anyone recommend anywhere that could do it?

Discostu:
Yeah drill some holes around it if you can get a drill in to do it. Then the caustic. An impregnate it more.  :daumenhoch:
This is very much a waiting game. So patients is the word.

bobbbbsy:
the person or people who did this deserve an awards for being muggy c**tS !
