Anodized aluminum post stuck in steel seat tube. Have tried the ammonia trick and the gently prying the split at the top of the seat tube trick. FRom what I've read, a solvent won't help. I half-heartedly tried a hairdryer, and an inverted dust-off spray (cold!)....I think I already started bending the seat rails.
Is there, perhaps, a plumbing-type tool that would clamp 3-4 inches of the seatpost, and allow me to twist the post with minimal damage to it? I have a bench vise but that would kill the post.
Any help appreciated!
Yes I already read the 14 ways....and yes I need to save both....

When I've needed to pry a stuck post, I have clamped the post in my stand. If you've got someone to help provide the stand some stability, using the frame itself as leverage, you can accomplish great things. Add some heat too.

I guess I could adjust the stand clamp to a stronger position. I usually run it fairly loose. I can't believe this happened! It seems like just a few months ago that I removed the post and frame-savered the seattube....so, I'm thinking that it just needs a good solid twist...I don't want to wreck the post (thudbuster), but will if I have to in order to save the frame.
I got out of the habit of greasing seatposts years ago when I had trouble with a slippy USE post....
I do have a new bike coming but I'm losing sleep over this until it's done!

How much heat can I add before compromising the frame? (I don't care about paint)

Are the frame tubes sealed? (Indy Fab & others do this...ie no breather holes in BB)
