Cruisin' on my Bluebird
If all else fails, before you give up on it. Find an impact socket that fits semi-snug down over the post, weld it to the seat post, not completely but just enough that the welds wont break. Hook up an air impact to the socket and go to town. Once it comes out, cut your welds, clean up the metal on the seat post and bam!Ohhhh it doesn't feel like I'm wasting any time! I've enjoyed playing with it - unfortunately as Shawn mentioned that darn seatpost is still holding on but oil oil oil
Never failed for me and Ive done it on broken stems too.
Best part is, alot of the time, the heat from welding to the post will often-times help release the post.
