Did bad rivets cause sinking of Titanic
The article does not amount to proof, but it is interesting. Another
one mentioned that if quality welding was available and used to make the hull, then it would not open up the way it did due to the collision. http://www.nytimes.com/2008/04/15/sc...15titanic.html |

Did bad rivets cause sinking of Titanic
Thanks for the post. I was one of the donors of period wrought iron
for the comparison testing. They (NIST)told me at the time that they'd keep me informed but I never heard from them.

So, did you provide a good rivet or the one with too much slag? Care to share anything? i Pete Stanaitis Ignoramus15568 wrote: The article does not amount to proof, but it is interesting.

Did bad rivets cause sinking of Titanic
I provided a sample of double refined wrought iron that came from bridge
spikes that were recovered from the Mississippi River where most of that bridge ended up after being dynamited to get rid of it. A guy up here "mined" these spikes from the head end of an island and tried to sell them as historical artifacts, but nobody was buying, so I bought several hundred pounds of them at about 8 cents a pound, 20 years ago. FWIW, these spikes are 3/4" square and vary from about 2 feet long to about 3 feet long. Most of them, as I receive them, are bent in "S", "U" and other shapes, for obvious reasons. They tell me that the bridge was made mostly from 12" square pine timbers. I never heard of this "best" and "best, best" rating. All I know is: Muck bar (right out of the bloomery) Double refined Triple refined Used (This is usually considered better than muck bar, since it has been worked more). For blacksmiths, this wrought iron, being VERY low in carbon content can be worked a high heat. It is soft and doesn't work harden. I am glad that none of MY early riveting was holding the Titanic together.

I think there also was a National Geographic article about the same time. Jon |

Even been on T.V. programs about the sinking. Post a question to him. I'm sure that you will get an answer. Bruce-in-Bangkok (correct email address for reply) |

First test was fine, sample bent a small, but measurable amount. The cold test, however, caused the piece to break like glass and bounce off the wall. They said the iron had a high sulfur content, that makes it VERY brittle when cold. This was with an actual sample of the Titanic plate brought up from the bottom. I think it was a Nova episode.

I think I remember seeing a painting of the other side with the plates separated along the seams. Maybe that was another shipwreck? Jim Wilkins |

Probably left there by the Spielberg crew during the filming for Titanic. You can see that same type of cup when they are working to raise the safe in the first part of the movie.

My "toy box" contains a small handful of crushed coal recovered from the Titanic. I purchased it from Ballard's group about ten years ago. Why? I dunno... Probably the same unknown reason why I bought a small piece of the Berlin wall when it came down... I can rationalize those purchases by saying that if I'd spent the same money on booze it'd have dissapeared down the drain long ago.
