[Closed] How salvageable is a bowed rim?

Never built a wheel before and bought a slightly bowed rim cheap thinking it could build back into something true.

At what point is it no longer true-able when you build a wheel? I've heard people saying that unless it's dented or fully taco'd then any rim should true. Is that right or bollox? Not sure whether to start on the build only to find, well, that you can't polish it merely roll it in glitter!

Should it be wall art and am I naive?

For reference:

Thanks

Ps yes for reference I have been trying to sell this rim but second guessing myself now whether it could actually work as a completely amateur first build.

Stw sense appreciated!

You would probably be able to build it and get it straight but the spoke tension would be all over the place because of the need to pull the rim back into the center.

Good for practice but don't get your hopes (sic) up about it being very tough.

That's well beyond its happy place IMO.

You might be able to get it vaguely straight with spoke tension alone but you'll have half the spokes too loose to stay put and the other half trying to rip the nipples through the rim, and as a result it'll probably go out of true on a daily basis. No matter how experienced you are at wheelbuilding, it'll be a piece-of-crap wheel. As a first build it'll drive you nuts and probably teach you bad habits along the way. What you want for a first build is a nice straight rim (and not too stiff).

You could bend it back into shape but you'll have to accept that the rim is weakened and will have a shorter life (and possibly a more exciting failure) as a result. And realistically you'll still have the previous problem, albeit to a lesser extent. To be honest, bending a taco back into shape is purely a get-you-home measure, not a let's-make-a-wheel-out-of-this measure.

I'd say it's hula hoop time.

If you want a well built, evenly tensioned wheel (which, let's face it, is what you want) then bin it! You could probably get it straight, but spoke tension would be all over the place, a minor hit would probably pringle it!

If you are desperate you can sometimes recover these by battering them against the ground with a tyre fitted. But it's never great and will make you cry for a first time build
