Damaged flying wire ends.

I've been offered a set of streamlined stainless wires for my bipe project
that have come off a ground looped airplane. The vendor says that only one
was very slightly damaged, the threaded end being bent just enough that the
rod end wouldn't screw in al the way. He straightened it with a plasic
hammer and says the rod end goes on fine now, but I'd be wondering....
Are these a bargain or a waste of money? they're virtually new aside from
this one defect. I'm considering getting them anyway and replacing the one
damamged wire if it comes to that, but in general, is this acceptable
practice?

Hmm, is it a flying wire or a landing wire? :-)

Seriously though, if you were to use it, would it thread in past the
area where it was bent? If so, how far? That to me might be the
issue. If there are enough threads above where the bend occured, and
you thread it in all that way then there wouldn't be much stress on
the part that had been bent.

The next question is: how many threads must be hidden for the wire to
be a good aircraft practice installation?

Good question! It's a flying wire, and not one that's paired. It is able to
be threaded all the way up now it's straightened. I'm thinking that it's
too good a dealto pass up even if I have to replace one wire.

I'd have some concern about whether the steel,
stressed beyond its yield point in being bent,
retains enough of its origional strength to be used.

I used to do a bit of sailing, and if you bent the "turnbuckle"
"screws" on the shrouds (trailerable boat), you could count on it
breaking in heavy weather whether you used it bent or tried to
straighten it. These were 300 series stainless, probalby 303.

It was "always" the non-wire attached one that bent, and they were
reasonably inexpensively replaceable.

I would NOT use it after it was bent.

I really thought this was a troll, but I see you are serious. My comment is
that you ought to replace that wire, and not even consider using it, even
though it looks good. Losing a wing, when a wire breaks, is a bad thing.
