Someone shoved a seat post that was too large into this Trek 460 frame. It’s been seized for who knows how long. Is the frame still safe if I can get this post out?

I’d argue it is not safe and not worth the trouble trying to take out the seatpost. The frame is already damaged beyond repair.
If it isn’t your late fathers special bike, let it die. You can still make a nice lamp out of it.

Ya, if this is seized due to corrosion and also mechanically wedged in, I don’t imagine you’ll get it out at all.

Is it safe? Most likely yes. The nature of the seat tube failure would not be catastrophic. But… let’s see the clamp-side of the junction lug.
However, you’ll never get a seat post to fit correctly in there again.

Bulging on the tube. It’s cooked. Really sad to destroy a frame over a few dollars

Did they pound it in with a sledge? That’s probably not coming out. I wouldn’t trust the frame even if you can get the seat post out and figure out how to get a new one in and stable.

New seat post would need to sit a good deal lower but the frame isn’t destroyed or unsafe.

That is a feat of effort! Unreal.

Seat stay bridge looks cracked at the weld, and the giant hole through the lug seems concerning. Depending on how it held up *after* removing the seat post, I may have thrown an extra long seat post in it and called it a day (assuming you can even find one/make it fit). But with the crack- nope.

as of now scavenge it for parts. but keep the frame, you never know what skilled people you’ll meet or if eventually a geenie in a bottle lands in your hands

Aluminium seat post in a. Steel frame will do that. Alu expands way more than steel so it probably welded itself together

Try clamping the seaport in a vice and work the frame free.

Ask Popeye if he can pull it out again. Easy!
Otherwise, yer screwed.

Not coming out unless you are prepared for even more damage to the frame. People do t realise that metal expands and contracts and can stretch too but when these things happen they lock. Same as when you tighten a bolt to the right torque setting or past it. What is holding it in place is the thread which has stretched.

Problem would be getting a seat post to fit as it is no longer the size that it should be.

You could probably film a YouTube series about this.

How the hell does this happen?

If you can get that post it’ll be ok. The key is buying the longest post you can find and insert it past the bulge.

Steel is an amazing material and can easily be worked with. It’s a question of how much effort and time you want to put into it. If you are skilled enough, You could find a way to make a jig to pull that seatpost then patch/replace/weld that bulge … but that’s a LOT of work.
I’d just find another bike that has the problems I CAN handle
