Building your own plane?

Yup. Rag and tube fuselage, all aluminum flying surfaces - 2 seet
side by side STOL highwing. Power on dirty stall about 18MPH, normal
landing speed about 35MPH - max cruise on 90HP between 100 and 120MPH
- cruise all day at about 85. Land and take off on a football field
without turning around or backtracking. Got a bad cross wind? No
problem - land it ACROSS the runway.

It's called a Pegazair 100.

I'm he OP. It so happens that the rear bolt was the one that snapped,
which seems to contradict your assertion about the design's weak point.

And, if I remember correctly, after only 15 years too :-)

This is false logic. There are at least 15 parts on your bike; by your policy we should expect catastrophic part failure once per year.


I'm not quite sure what you are trying to say. A bolt that broke after
15 years of use is somehow associated with something that breaks
annually?


Exactly. If your stem fails once in 15yrs, on the average, and so does your seatpost, and so do your bars, forks, and crank, then something will fail every three years.

It is a ridiculously high failure rate.

No, the whole bike will fall apart every 15 years, so do what most
guys do and replace the bike every 12-14 years - and suffer no major
failures - - - -

Why do you equate the failure of one part to the failure of any other
part? Does the fact that the tree in your front yard fell down mean
that your house will fall down? Or that because Joe Boudrou was hit by
a car while crossing the street mean that you can't cross roads as you
are certainly next?

You don't have faulty logic. You have no logic at all.


My logic is perfect. I made no such absolute statements, my statement is prefaced with your 15 year period. You seem impressed with that as an MTBF for an 6mm bolt. I am reminding you that that bolt is not the only such part on the bike, (it has a twin in the seatpost, for example), and so to calculate your average E.T. between scary failures, you must divide that by the # of such parts on the bike.

Viewed in this light, 15 years is an unacceptably high failure rate.

Yes, I am assuming that you would be similarly impressed by a set that failed only once in 15 years, and by such a post, and such fork, and such a bars. Hence the opening "If". Again: IF your stem breaks once in 15 years, AND so does your seat, your post, your forks and bars, THEN, you will have a scary failure once every three years, on the average.


.... unless they were all perfectly designed with precise working lives
of 15 years, as in this classic poem:

Well, I guess I was probably aware that the bolt on the stem isn't the
only part on the bicycle, but your assertion that because one bolt
breaks it somehow relates to any, or all, other fasteners, or for that
matter anything else on the bicycle, is certainly not logical.

You seem to be arguing that one bolt somehow relates to all other
bolts and thus a failure of one bolt will be related to possible
failures of other bolts. It doesn't, you know. Bolts are of different
size, different materials, different loads imposed, etc.

As for 15, I'm not sure whether there are 15 bolts on a bicycle. Nope,
I just went out and counted the bolts on my road bike... only 10 :-)

Remember, our friend Jobst died recently from injuries resulting from a frame failure. He had been riding the frame since 1962 or something like that. Now, I'm not saying anything one way or the other about that event. I am not trying to argue that it should have lasted longer, nor, on the other hand, that he shouldn't have ridden it as long as he did. But I think that it provides an interesting reference point.

Quite typical of Nissan - possibly due to their alliance with
Renault. I see a lot of good looking Nissans in the wrecking yards
because when they start to fail it's a fast downhill spiral - so a lot
of people scrap them rather than starting to repair them.

Just an observation -

I suspect that it was the usual Japanese tactic of taking a design
which works and then figuring out how to reduce the cost of making
them without losing the quality (or much of it). The early days of the
35mm cameras is typical. The Japanese started making copies of
European 35mm cameras. Then when the Korean war started the news guys
discovered that they could buy a Nikon, just as good as a Leica, for
half the price.

fleet of Datsun pickup trucks at one site that failed in an almost
identical manner. If one major part failed you could be sure that
nearly all other major parts would fail in the immediate future.

Canny people those Japanese :-)

Quite typical of Nissan - possibly due to their alliance with
Renault. I see a lot of good looking Nissans in the wrecking yards
because when they start to fail it's a fast downhill spiral - so a lot
of people scrap them rather than starting to repair them.

Just an observation -


I suspect that it was the usual Japanese tactic of taking a design
which works and then figuring out how to reduce the cost of making
them without losing the quality (or much of it). The early days of the
35mm cameras is typical. The Japanese started making copies of
European 35mm cameras. Then when the Korean war started the news guys
discovered that they could buy a Nikon, just as good as a Leica, for
half the price.

More likely the french management. Toyota, Mazda, and Honda don't
have that problem. Mitsu deams to - and they have just been taken
under the wing of Renault/Nissan.

Default Selecting An Appropriate Bolt

With all ofthe replies about just about everything else, did you get a definitive reply that ANSWERED your question about whether to use a Grade 5 or Grade 8 bolt?

Sorry - I hadn't checked the newsgroup in a few days.

I was pretty well convinced to look for a Grade 8. Right now I took the
same bolt from another of the same stem that I had on a previous
bicycle, and am using that for the time being.
