That gets hung on the ceiling. Seriously.
My shop teacher (Motorcycle Repair) liked to say that "all expert mechanics are standing on a heap of broken parts". We just don't get to see them when we go to them for advice.
You Sir, are on your way to expert mechanic status!

^^^^ +1; ceiling / wall hanger. Just so you can say "really, I'm not making this up...".
Yeah, I remember your posting to the Catch of the Day thread, wondering what would happen with that seat post. Trek might just honor the warranty, but would you want to? And for what, some import frame glued together from old beer cans? No, this is a keeper.

The pictures would make a good public service announcement entitled "Didn't have the time to grease the seatpost - no big deal."

Maybe more of statement about the strength of that model of trek frame as I've found the seatpost lug usually shears off before the frame breaks or I give in and get out the mother of persuasion - ie the sawsall.

Or a statement of what happens when you use the frame as a 2' cheater bar.

Well, the seat tube should be stronger now with the added helix...

Exactly. Good frame ruined by impatience.

Just this evening I was thinking of this thread while trying to free a seatpost in a Trek. Had been soaking in Kroil. Felt it budge just a little. Then came a mental image of Sloar's bike...put it back in the stand and hit it with more juice.

These pictures frighten me. Did you soak the seatpost in anything or try to freeze it before attempting to get it out?
I have a stuck seatpost in an old bike I really like, but since the seatpost is at about the right height I haven't done anything about it. It's been stuck since I got the bike a few years ago.
At some point I will attempt to free it up. My plan will be:
1) Repeatedly soak for a month or so in Kroil.
2) Freeze the seatpost/top of frame with salt/ice in bags (or maybe dry ice) for a few hours
3) Clamp a large hardwood clamp around the post and attach a 10lb slide hammer
4) Wrap a towel soaked in boiling water around the seat tube (to quickly heat the tube relative to the post) and start banging away with the slide hammer
I'm hoping I can save the post and frame. I hate the idea of twisting the post to free it up, as frames aren't really designed to take forces like that. Most corrosion is brittle so any sharp impacts you can put on the post should help to break it free.
Is this considered best practice or is there something else I should do?

I stopped using excessive force on my vintage road bikes years ago, right after I totally screwed up this early seventies Torpado. As I twisted one way and the other, hoping for release, something released all right - snapped both seat stays free from their brazed attachment to the seat lug. Pooey stinko..!

Maybe a lye soak would have been your other option. That's pretty ugly. That hole in the lug where you heated it?

I soaked it 48 hours and heated it with a heat gun, not to extreme. I really didn’t think I applied to much force. Nothing I haven’t done before with success.

Heating would make sense if it were a steel seat post in an aluminum frame.
