the lug is steal. the tubes are aluminum.
Update: Got it out.
used the hack saw method. Simple. I wish i would have done that a week ago. Nothing to it.
Here is the run down.
1. lop the seat post so you have about 1 inch sticking out.......(in my case that is where i broke it off trying to free it)
2. get a fine tooth hacksaw blade and duck tape it to a paint stir stick for a handle
3. stick it down there and get sawing. I tried to keep the blade as flat as possible on the length of the post vertically as i sawed. It only took about 30 minutes.
4. Once you get close to where you think the frame is.....stop
5. start another cut about a pencil width away from your frist one. Again cut to the frame or damn close and stop.
6. now you can take a break. Come back to it and carefully and lightly run the saw blade up and down a few more times in each slit and again...stop
7. Put a flat blade screwdriver in your exposed seat post and twist back and forth. The long narrow piece will snap off and fall down to the BB
At this point i had a long narrow chuck cut out but that sucker still would not move. No problem......I tried crushing it in on itself and twisting. Nope....the visegrip cracked the post all to hell after many attempts. I could not believe it.
at this point i thought.....what the hell.....and started doing the same process on the other side of the post....
I cut another notch out and it fell into the BB. At ths point the 2 remaining halves came out with the same twist of the screw driver.
Problem solved.
I went down in there with a small wire brush and cleaned up the inside of the tube real good where it was corroded and it is good as new.
simple process really. Glad i opted to try it. All the forum posts i read sounded like it was world war III trying to cut one out but it was very simple.
I can see if you had a steel one. That would be HARD to do.....very hard. Alloy was so soft and if you are careful and dont rush....its simple.
2 beers....some good tunes ......made for a productive saturday
thank you all for the help and suggestions!
