is it F**ked ? can any one help !

[BENDYCAT ELEVENTEEN]

Was trying for the hundred time to shift the old renthal post in the Goose TS  - have nearly tried every thing - soaking it in vinegar - wd40 - coke - heat - cold
So the next thing was to drill a hole in the post (can always get another  ) then a bolt through it andhit with a hard plastic hammer - didn't shift at all  then it shattered and now has totally F*ing P*ssed me off as there is only a little bit in there  it must still go down for another 6 inches !!!
 
So how the F*&k do i get it out now ?

can anybody do it ?

can it be melted out ? drilled out ?

if i try to bang it back down - i think it won't go down far enough for a new post to fit !

please bloody help, as this is driving me nuts

cheers B

if its alloy then melt it with costic  or cut down it in 3 equal slices with a hacksaw blade

[Munnyella]

I think i'd take it to a local engineering machine shop and ask if they can drill it out for you.

I bet the hole through the post isnt big enough to get a hacksaw blade in is it? if it is, you could try to saw through the length of it, but it would take forever and you'd probably throw yourself under a bus instead of finishing it!!

Good luck with it anyway.

You have a case of electrollosis there i believe mate!

Thats where the alloy and steel react and semi fuze! remember seeing a bmw back in the late 80's early 90's drive with alloy wheels and no bolts to try and free a wheel of that had done this same thing!!

I would imagine that u need a pillar drill and some precise drilling to remove that !! heat would have helped a bit poss b4 it sheared of!

Costic soda as Dan says, then maybe get a large tap that fits the inner hole & try to turn it out 

[trasher]

i.d try the costic route

but another way is ,if your having a new finish on it is ,,drill a hole in the bottom bracket

then get a long bit of steel rod ,,,you  can get 6mm reinforcing bar ,,then twat the fooker with a hammer onto the bottom of the post

then reweld the hole up and get it finished

i'd use a pillar drill starting with a drill bit not much bigger than the hole in the post then going up one size at a time 

[sawzall]

i got one out by using an airsaw with a long blade and cut 4 slots around post and it came out in 4 bits
but if all else fails i would drill it out so there is only a small bit of post left and remove the last bit soaing it in caustic
this would save any chance of drilling the seat tube

it's a pain in the rectum, but there is no short-cut now. Caustic will work, but it's a awkward thing to get into a bucket of strong enough caustic. The sawing method works best if you can get the blade down the hole. I melted it away a bit with caustic and then used a boa saw to get it finished. Never again, i'd drill it at work first, but i wasn't working when i had this to do.
ahh well, hard work ahead.

what about a metal Dremel wheel and slice down where the slit is in the seat tube. That may loosen it to split it.

[BENDYCAT ELEVENTEEN]

so just to ask those who have used caustic soda - if i make a tube to hold the soda in and around the seat tube - will it eat the frame (gonna be re-painted) will it melt the seat post all away after a time or are we hoping to loosen it - drill a small hole in the post and hook it out ?

I just want to check before drilling !

to those who sent pm's cheers - will get in touch when i find out what peeps say

i will not be defeated 

cheers B

I melted one out of a Mk2 Cromo... with Caustic... turned the broken post into black mush...

[BENDYCAT ELEVENTEEN]

well cheers MartyC looks like that will be the way to go 

was a good read and very usefull - gonna try it when i get the right amount of time to sort it out - and with a bit of luck it should work the same and then i can start on the build

thanks to all and well done to MartyC for the very much needed info

now to melt 6" of stuck seat post 


cheers B 

[monkeybat]

Im so glad i found this thread. I have been doing something similar to this for the last month. Been soaking the seat post hole in WD40 and the next step will be getting it drilled but i might have a go with the caustic soda. It must be an alloy seat post cause it has welded inside the post and i feel steel would not stick like this. Let another botchet job boy have a go and i found he had drilled a hole in the bottom bracket to get it out. Any idiot could see it had a cable run accros the bottom of the seat post so it could not be done that way.
Cheers guys.

A hot mix of caustic soda and water will munch through this aluminium post and shouldn't touch the alloy or steel frame.

B, caustic soda, done it myself once and worked a treat 

[Nana]

Caustic.....Also good for your drains 

Suprised heat did not break that seal....one being steel and the other alloy 

[AKGOFF]

Why don't you try dumping it it in the neareset skip (Pooch's House) and getting something thats not fooked in the first place you tit.

[Pooch]

if its alloy then melt it with costic  or cut down it in 3 equal slices with a hacksaw blade

Soda trick works..hot water with it and away you go.. Did it on my hutch.

[B17SSY.T.A]

Lots of good suggestions there , just wanted to say " Good Luck " with what ever route you take and post some pics after you get it out  ... which you will
