Bumper Air Tanks Yea or Nay?

Paul, he is from Michigan, maybe that's got something to do with it...

It's obvious, Jeremy, that neither of them have bothered to try to understand a word I have written.

*sigh*

For crying out loud. Can you Indiana people not read? I never said it's not going to leak! I said it's not going to shrapnel!

... we've had 5 hard lines rupture in 4.5 years.

Right. And what happened when it ruptured? Did the whole shop air system suddenly fracture into eleventybillion pieces and kill everybody in the building? NO!!

The air came rushing out at the point of the leak, you fixed the leak and went along your merry way.

Whatever... I'm done trying to figure out what the color the sky is in your worlds.

Yep. Air bumpers are going to cause the downfall of civilization as we know it. Mass hysteria, nuclear war, dogs and cats living together... it'll be anarchy.

G'nite, johnboy...

thank you for reinforcing the fact that the dumbest people i know live in Michigan (though not ALL that live in Michigan are dumb).... apparently you missed a little something... something about beating a pressurized vessell on a hard surface vs a suspended airline that literally had not been touched by human hands for years.

Firstly this is officially the dumbest thread, with some of the most unfounded and foolish posts EVER.

Second, I can't believe I got sucked into it AGAIN. I'm so ashamed.

Third Jeremy that was pretty funny.

Fourth, Can, I'm always in agreement with you, and usually find you to be the pillar of sense and decency, so I'm surprised beyond words that you truly feel this mod out shines the risk factor involved with suspension, brake, steering mods that we consider typical here at CK5. How in the world do you defend that? Not that it matters you're still the bomb!

 

[beater_k20]

please, do tell what makes a spring swap or an upgrade from an inferior braking system comparable to potential shrapnel?

 

[fireplug]

right... i'm going to put 10x atmospheric pressure (we'll assume 14.7psi) into a large tube (which will look gay BTW)quote]

I'd better clarify that I meant this. The rest of it is all crap!

And this tops out the crap meter! I'll stop posting now.

Too be absolutely fair I'd say not only is he right and on the ball, but CK5 dances in, around, and on, WAAAAAY more dangerous modifications openly everyday. ie. disk brake swaps.

Apples and oranges, my friend.

99% of the modifications we do either used approved parts that are slightly modified yet still do the job they were intended for, ie disc brake swaps, or use parts that are specifically engineered with the particular modification in mind.

Most of this thread discusses homemade bumpers, which are A- not necessarily built by journeyman welders and B- not certified or inspected or built to any set standard.And therein lies the danger.

If we were discussing the installation of professionally engineered and built air tank bumpers, you would never have even caught me posting here in the first place.

Ok one more post !

My argument is that whether the mods are 'approved' or only 'slight' modifications, they are mods that if ill performed can easily and directly be attributed to injury and death for the operator, passengers and other road users.

There are far more unqualified shade tree mechanics than then licensed mechanics here choosing grades of metal, and hardware, welding, designing, engineering, and yes even driving, without the appropriate skill base to be doing so "safely", and yet it isn't questioned.

 

[fireplug]

And for what it's worth I'd rather "risk" following a guy with air in his homemade bumper, than yank someone out with the attachment points that everyone welds onto their homemade bumpers. That is a far more likely and realistic risk. One never mentioned in this post as far as I can remember.

Or how about following someone on the highway with their homemade swing out tire carrier bumper? I don't see anyone concerned about this!

I think the commonality of the 'usual' mods give the false impression of safety in contrast to the 'new' or less common mods.

 

[Can Can]

You're right on all accounts.

And if I saw a thread on a different topic that was as full of potential misinformation as this one, I'd be on it like a beaver on willow. When it comes to my attention that some half-truths or irresponsible info is being dispensed, I have an obligation to say something. That's what my point has been throughout this thread.

Luckily, it doesn't happen very often around here.

actually, it is, in the VERY post you responded to...

It's not "my decree", it's physics. Ask anyone with any engineering knowledge and you'll get the same story.

You've been getting the same story from me. Does my degree in Mechanical and Manufacturing Engineering not count?
If you truly understood all of the factors involved in a flat endcap welded joint I think you'd have a different opinion.
BTW, I asked about the Stress in the welds, not the Strength of the welds. That you appearently don't understand the difference is telling by itself.

snip....

If we were discussing the installation of professionally engineered and built air tank bumpers, you would never have even caught me posting here in the first place.

Nor would I. However the potential does exist for a brittle failure if certain conditions are met. Which will result in shrapnel.
It is prudent and responsible to point out the problems such a design has. Engineers call this being "Conservative."
If a person decides to go ahead and do it anyway, then they've been warned.

I think this thread has caused enough dis-harmony. Unless attacked I am thru with it.

 

[goldwing2000]

Yep. You're all right. You win. I guess I'm just "geographically dumb".

 

[tRustyK5]

All y'all have beaten the dead horse into a bloody lump. Everyone has had their say and then some...

At this point all I see is bashing from both sides so I'm going to lock this one up.
