I HAVE THE STUCK IN SEAT POST FROM HELL. HELPPPPPPPPPPP.

[dordymush]

right then i've hammered it i've sawed it and i've left it to soak in wd40 for 3 days but its still solid.
other than me smashing the lot up in a minute  .
is there anything else i could try.
i've had hard ones in the past but this thing is a joke.
i was gonna heat it up but i think its brazed so will this fook the braze up if i do.
HELPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP

[dordymush]

I've done a few of these and I have two methods

1) The hook and pull.

A 10mm bar bend a hook onto either  end of it (might need a big vice) push it down catch on bottom turn bike upside down so its above the vice, or work mate catch frame or seat tube edges so they cant go anywhere and hammer the fook out of the other end of the hooked bar..

I've had fantasies about making a device that uses something like  one of those plasterboard fixing screws with two wedges so you can drop it down and it will open and catch on the bottom edges of the seat post but never needed it

If that doesn't work then

2) using a hack saw or dremel carefully cut through the inner diameter of the seat post to the out side, (like really carefully dont go all the way through, leave a sliver of thickness that can be broken with a stanley then peel the post inside itself with a hammer or stilsons. If its alloy then it a fook sight harder because its a thicker wall.

I that doesnt work then

3) Hide the frame in the attic, give up old school BMX live the rest of your life in shame..

You know it makes sense 

[monkian]

What about a soak in Diesel or Petrol?
...then chucking a flaming rag at it

[brummie]

been havin a think, if there is still some post showing could you drill a hole through it and stick a long bolt through? you could then hammer the bolt ( either sideways or down ) just a thought  

[tolaknawris]

grit & total determination is what is called for

I read somewhere the other day of a brilliant idea.


The bike was put in a vice then the guy bolted a spare handlebar stem on on to the seatpost, he then used a long hollow pole which he placed over the stem ( the part of stem that goes in to the head tube) and turned it using the long pole as leverage.  Every time it's been a success apparently.

  If it`s an alloy post you could plug the hole from inside the BB & dissolve it to death? The drilling and shoving a bolt through it has worked for me in the past

A guy did this dissolving thing on singletrack the other day http://www.singletrackworld.com/forum/topic/swollen-seatpost

I like the sound of the stem/big time leverage thing, I'm defo going to try that next time.

this has worked for me , clamp old stem onto seatpost , that whack it with the biggest hammer you got
its not subtle....but then neither am i


(i put the bottom bracket of the frame onto the base of a garden parasol thingy while i whacked it , he he he )

Seat post clamped in to the vice, then turn the frame

exactly word for word what i was gonna say

[stidds]

Is it a valuable frame Dave?

If not this is what it did to Jo's mid-school Redline when the seatpost wouldn't come out no matter what I soaked it in.

1) Drilled a hole through the seatpost that was visable.
2) Find a ballbearing that fits inside the seatpost and put it in.
3) Put a strong bolt through the hole I drilled in the post.
4) Turn frame upside down.
5) Drill a small hole in the underneath of the bottom bracket.
6) Put a metal bar though the hole in the BB and up-through the frame and into the seatpost which then rested against the ball bearing.
7) Hit the fook out of the bar.

Drastic I know, but it worked when all else failed.

it's a nightmare dave. got 3 myself at the moment. an alloy that's welded itself in. that's being melted out at the moment with caustic, one cro-mo and the fecker has snapped just at the top of the seat tube using the vice and frame turn method, heat didn't help before that. it's gonna be a carefull sawing job. one i haven't tried yet, 2 nighmares at once is enough
just keep at it dave, before this one, the vice and turn the frame method has always worked for me, good idea is to find something to put inside the top of the post so you don't crush it too much and cause it to split. good luck.

Hi all

I hope this helps.

I said this years ago, but as before - really stuck metal is broken by freezing.

I worked with the Environmnet Agency for a while and the engineers used to freeze lock motors / guillotines and other outside large machinery when replacing stuck and corroded metal parts.

nice one bud,going to have to get some of that

[Juju]

Can I ask, whats the frame, and what's the seat?

If it's corrosion expansion from rust, ie cromo to cromo, then try the above mentioned methods.

I seem to recall that if its ali to cromo, then its a chemical reaction between the metals, not rust expansion, and so something like amonia is the way to go.
