Big, bigger and mind boggling..

What's the biggest nuts and bolts you've ever seen? A while ago someone asked what the biggest press was. Russia has a 75,000 metric ton forging press, that's 165 million pounds!!! Among the parts it produces are titanium aircraft components for the Airbus A380. The largest presses in the US are 2 seperate 50,000 ton(100 million lbs) at seperate locations. They were both part of a US heavy press program in the early to mid 50's. The Mesta machine operated by Alcoa needs repairs estimated around 68 million dollars. The machine has some threaded columns that are 40 inches in diameter with 52 inch diameter nuts. The heaviest of the nuts are 55 tons or 110,000 pounds each!!! Hard to fathom how big the wrench was to tighten them or what they were torqued to??? LoL Dave
 
The largest nut I have seen is 73" from top to bottom and weighs 235 pounds.

I see it every morning when I look in the mirror to shave.
 
The biggest nut I ever had the privilege of tighten was 8-inch. Had to make a box end wrench for it out of 1-inch plate. Can’t remember exactly what they were on it was in the mid 1970’s in a nuclear power plant.

I have never been around any really big presses or breaks. My brother-n-law was telling me he was involved in building a break that was used to bend 4-inch thick plate. He Tig welded all the hydraulic lines. Used consumable inserts, 100,000-PSI! :shock:
 
Worked in a very large power house. The high pressure steam turbine shell bolts were six in. in diameter and about 4 ft. long. I can't really remember what size the nuts were but I do remember we used a 3 1/2 in drive impact wrench to tighten them. We hung it from the overhead crane and it took three men to operate it.
 
Your Funny,,, and here I thought the nuts I had to deal with was Jimmy Howell and Dave2 ...
ha ha ha ha ha ha ha ha ha,,,,,
 
Those are impressive, to an old dog like me. Sad fact of the matter, the emphasis is on "old dog".
As America gave up her manufacturing might, the younger generations have no interest in things like that. This was becoming apparent in rhe 70s in high school. Films about manufacturing, steel making, mining and heavy industry were most fascinating to me. These days if you even see something of interest like that and point it out to a member of the youngers", you've won one getting them to look up from their gameboy or cell phone. I say this being the father of a 21 year okd kid in college who called me back in July and asked 'Dad both front tires on my truck are almost flat, what do I do?".
The most sadly hilarious example of this was last year. BIL has an 8 year old son who BIL got hooked on a gameboy. July 4th family picnic I mentioned to BIL that he should really limit that as those things are like crack to a kid, and I was speaking from experience. I was rebuked with BIL stating "I like them myself". So I shut up.
BIL is an avid deer hunter and deer season last year he took nephew hunting with him, the classic Father/Son scenerio. All went well, Dad watching for deer and son deeply immersed in his gameboy. A nice buck and 2 doe came into a clearing several yards away and stopped. BIL nudged nephew to look and nephew had a fit because Dad disturbed his game. Of course the deer didn't stick around to see what the fracus was about. I had to leave the Thanksgiving table for a few moments to maintain my composure.
These days hearing stories and seeing pictures and films of the things that made America the great country she WAS, are what grabs my interest. But sadly folks us "old dogs" are a drindling audience".
 
My dad use to work at Alcoa. He buddy that was a millwright. They would wrap a sling or cable around those nuts and use the O.H. crane to turn them.
 
Biggest nut I ever saw was the nut that hold the screw on to the USS JFK carrier I was on. Now as for how big it was I do not know but it was big and there where 4 screws on that ship. But on the other hand maybe it was on the USS SSBN633 sub I was on.. Hard to tell for sure which was bigger but both where big
 
you are right gotta balance that stuff. We let the kids do is some, not during the week and not if there is anybody around. Often tell them "I didnt have any grandfathers growing up, you do and put that away and talk to them." -they do and they like to do lots of other stuff too. Thing is it is the parents job to make sure they do, go to museums, shows, fairs, family trips, work on family projects together.
 
There is a fellow who serves on the Zoning Board with me that worked for Bethlehem Steel .. last nite he was teling us about the 300 hundred ton molten ladles they handled ,, Also told of winning a bid for scrapping 19 steam locomotives some 40 yrs ago , that got melted down at his plant ......
 
S.Crum I love your story!
I have four grandsons who are hooked on those game boys. We don’t get many nice days here in the NW, but when we do, those boys are in the house playing video games!!!!!! Drives me crazy!
When I was a boy my mom would throw me out of the house just after sunup, I could come back for lunch then off again until just before dark!
Kids now a days! :cry:
 
This isn't about nuts, just big stuff.

I once took an evening class in diesel injections systems at our local community college. The instructor told the class that in Saudia Arabia, and maybe elsewhere, on oil rigs they have diesel engines so big you could put a regulation poker table, with 4-6 players, on top of one of the pistons.

The instructor said they're set up to do all maintenance while they're running, they run about 200 rpm, and might run for years without stopping.

It is mind-boggling.
 
Yea, I guess ships propellors would have some really big nuts. With the largest container ships having 110,000 HP, I think you'd need a pretty big nut to hold the prop on. Dave
 
Check out Edmonton Exchanger's website. They have some pictures of their new monster rolls. The largest in N. America. 6 inch cold rolling capacity and 11 inch hot rolling capacity! They recently made 18 shells over 8" inches thick but used their older, small rolls. Dave
 
I heard about a large construction job that was about to start.The contractor was getting the tools and material together.One of the first orders was for a boxcar load of soapstone!
 

Boxcar full of soapstone :shock: ! I bought a box 10 years ago, used about half of it so far. :lol:

A few years ago there was a TV show, (Discovery Channel I think) it was on the Hyundai Corporation. The show was on how Hyundai builds super tankers. Amazing! If Hyundai gave tours to the public I would fly to Korea and spent a couple weeks walking through their facility.
 
When I was a kid, the neighbor 2 doors down had a shop/ small store behind the house with access to a side lane, same lane I still reside at, and in the shop was some( I did not know much about them at the time) turn of the century gasoline industrial engines, ( I have photos) meticulously restored and or maintained. One was a big General Electric, that powered the draw bridge over the nearby Hudson river, I took photos of everything when they had the auction, after his wife passed in '98.

Back to the point, Mr. Miller was just a genuinely great neighbor and a great friend of any kid interested in anything mechanical, I'll never forget him, as good neighbor, friend etc., I've often wished I could have gotten to have known him longer, he passed in '90.

In his shop, and I noticed this when I was a kid, was a giant nut, back then it was huge to a young kid like I was, thinking of all the things with nuts and bolts, nothing was even near the size of this one, and for some reason I marveled at it everytime I saw it. Many years later, just after his wife, "Pal" passed away, the neighbor to the left, daughter, was left with the estate and the disposal of same. In conversation with Elsa, about the Millers, I had mentioned my childhood memories of this giant nut, + many other things, she knew the previous owners of our farm and it was a great thing to have met and spoke with her as her parents were actually the neighbors to the left and I never had met her before.

The following Christmas, I went up the road to another friends, a small gathering of friends, exchange a few gifts, socialize, few drinks etc. Well my friend hands me this box, with a greeting card on it and says it's heavy, real heavy, so use care. I'm clueless, like what kind of prank is this..... ? LOL. Well you know, in that box was that giant nut from Lou's shop, and in the card was 2 old photos of our farm long before we owned it. Elsa had contacted and gave my best friend these gifts, as at the time I worked out of town and was not home often, what a surprise, what a great surprise, to have something from Lou's shop, as the things he had that were auctioned were very rare, unique and valuable, but this nut, was something no one was interested in and probably would have been scrapped or in the dumpster. All those years later, looking at the nut, does not seem as big as when I first saw it, but I just measured it, 5 1/2" across, and it's blank, no threads. It did have a purpose though, in Lou's shop it was a counterweight rigged to a chain, for a sliding door, as I recall, I have the chain too, kind of a silly thing, you can't imagine the expression on my face when I opened the box, was priceless, just like Lou was to all us kids back then, they never had any children, but were the kindest people, I only have 1 neighbor left from those days, nicest people you could ever know, seems that was a lot more common years back. I should scan the photos from his place, so glad I took those for the scrapbook.
 
You know I'm not 100% sure what years it was but would have been around 1976 give or take a year or so. If I remember right I was on the blue crew but it has been a few years and a lot of sleep and beer LOL. So why do you ask?????????????? Oh by the way I was a nav. E.T.
 
By the 80s I was back home here on the farm. I got out in July of 1980. I did like Scotland and on my 21st birthday I got so drunk I had no idea how I got up on my bunk that night and that was when we where switching crews so we where still in that bunking barge and I was on the top which as you know was 4 high
