bent frame.....what now??.....pics.............
I started a thread in C & V to ID a $10 Peugeot..
https://s246.photobucket.com/albums/g...geot%20Course/
only to realize it has a bent frame from a front impact collision. No great loss; only $10 in. So I stripped all the stuff I wanted and now I have this bent frame. Is it repairable? I have no intention of repairing it, but I don't wanna pitch something usable or valuable. I also don't want some kid finding it in the trash, building up a ss only to get hurt because the frame fails or the geometry is screwed and causes a crash.
Destroy and pitch?? Sell/give away with disclaimer??

I think cudak888 on C&V had an old park tool frame straightening tool he wanted to try out.

I would think that the frame is still rideable. Those old steel tubes are strong as hell and the geometry is already so relaxed that it might aid from this adjustment hahaha. Sell it with a disclaimer.

Toss it. Salvage the fork, and sell it on ebay with a disclaimer.

The fork is almost surely bent back too.
The most you can lose on this bike, until you try to fix it, is $10.00. There's a lot of wisdom in knowing when to walk away. If you're worried about some kid trying to salvage it you can hacksaw the top and down tubes.

I was wondering about the fork too. I'm no engineer; but I'd be concerned about the integrity of everything forward. Thinking it through I realize that it took quite a lick.
Im thinking about some kind of "found art" project.....a mural...or lamp........maybe a hood ornament!!
Thanks for all the input...

i would not worry about the forks or the frame. i would drive it like that. it looks safe to me. if the top tube and bottom tube were bent then i might be a bit worried.

It can probably be fixed. There is a tool that is/was available where a bar goes into the headtube and a threaded rod pushes agains the bottom brakcet shell to push the head tube back to it's home position. THe frame has been damaged and will never again have the same straght as when it was new, but it will likely be ok to ride.
If the fork is not bent (put it on its back on a flat table and see if it is at all arched such that the crown is lifted off the table. If it is bent, toss it and get a replacement. If it is not bent, ride it.
Disclaimer: Check very closely for cracks in both the frame and fork. Riding a damaged (or undamaged) bike can cause injury or death in any number of ways. Take you life in your own hands. I would ride that bike after repair, but that doesn't mean you should.

Keep in mind that not only may the fork be bent back but it the blades may be bent back unevenly or to one side and the spacing may not be correct. That is not a problem you are going to be able to fix, period, as there are too many variables and too many specialized tools required.

It's scrap.
If the impact was hard enough to bend the frame the fork is also bent.
Throw it in the bin.
If you want to keep a kid from building it up pop the headset out.
Enjoy

In general, it should be possible to straighten the frame (perhaps using a tool like Cudak's Park frame straightener), but what concerns me in your case is that the upper head lug appears to have separated from the top tube:
This raises concerns for the integrity of the joint itself, and may mean a proper fix will cost more than the bike is worth.
There are some decent components on the bike; you might do well to transfer what you can to a different frame.

Bicycle Repair Man !!!
Can it be straightened ?
Probably.
Should it be straightened ?
Only as a practice exercise.
The frame is toast as the integrity of the joints has been compromised.
This is bad advice...

John knows more about frame building than most... his advice is solid.
When we get frames like this at the shop we strip the useable parts and then cut up the frame so that no-one pulls it from the scrap bin thinking it can be built into a rideable bike.
