      @John S he worked in the Cols. Oh plant, it was a typical war era hell hole. 100* or better and oil vapor and burning metal from the heat treat area hanging in the air, Dad said oil would drip out of the ceiling and into their food at times and that they carried guys out of there feet first plenty of times. He set the grinders up, it would be a Sun evening supper time and the phone would ring, it would be his boss asking if he could come in and help them get the machines set up right. He went every time, if I was half as tough as he was I’d be happy. He just turned 85 and has had Parkinson’s for a few years which I’m sure his job had something to do with that but he’s hanging in there. It was better than the coal mines of SE Ky but still a hard way to make a living. If you ever listen to the song readin writing route 23 by Dwight Yoakam it’ll tell you the story of thousands of guys like him. Sorry to ramble, I’m just pretty damn proud of my Dad and all the blue collar people that bust their asses for every cent they make.

      I probably use some of the machines you built! Cant say where I work or what I make, but I use some ancient Cincinnati grinders that have been retrofitted several times over with new technologies to automate it. CNC controlled dresser profiles, automatic diamond turners, servo driven infeed and plunging, variable mag chuck power, the work speed, finish speed and the whole grinding process can be altered in seconds with a few taps on a touch screen. Roller dressed cutters for conjugate parts. We can maintain a precision of nearly 1-2 tents between pieces.
      They are old but in a single 8 hour shift I can easily produce over a thousand pieces (when my coworkers aren't holding the cell back).

      Warning: The next generation might just be the biggest pile of idiots in U.S. history

      I have this ongoing discussion with a longtime reader who also just so happens to be a longtime Oakland high school teacher, a wonderful guy who's seen generations of teens come and generations go and who has a delightful poetic sensibility and quirky outlook on his life and his family and his beloved teaching career.
      And he often writes to me in response to something I might've written about the youth of today, anything where I comment on the various nefarious factors shaping their minds and their perspectives and whether or not, say, EMFs and junk food and cell phones are melting their brains and what can be done and just how bad it might all be.
      His response: It is not bad at all. It's absolutely horrifying.
      My friend often summarizes for me what he sees, firsthand, every day and every month, year in and year out, in his classroom. He speaks not merely of the sad decline in overall intellectual acumen among students over the years, not merely of the astonishing spread of lazy slackerhood, or the fact that cell phones and iPods and excess TV exposure are, absolutely and without reservation, short-circuiting the minds of the upcoming generations. Of this, he says, there is zero doubt.
      Nor does he speak merely of the notion that kids these days are overprotected and wussified and don't spend enough time outdoors and don't get any real exercise and therefore can't, say, identify basic plants, or handle a tool, or build, well, anything at all. Again, these things are a given. Widely reported, tragically ignored, nothing new.
      No, my friend takes it all a full step - or rather, leap - further. It is not merely a sad slide. It is not just a general dumbing down. It is far uglier than that.
      We are, as far as urban public education is concerned, essentially at rock bottom. We are now at a point where we are essentially churning out ignorant teens who are becoming ignorant adults and society as a whole will pay dearly, very soon, and if you think the hordes of easily terrified, mindless fundamentalist evangelical Christian lemmings have been bad for the soul of this country, just wait.
      It's gotten so bad that, as my friend nears retirement, he says he is very seriously considering moving out of the country so as to escape what he sees will be the surefire collapse of functioning American society in the next handful of years due to the absolutely irrefutable destruction, the shocking - and nearly hopeless - dumb-ification of the American brain. It is just that bad.
      Now, you may think he's merely a curmudgeon, a tired old teacher who stopped caring long ago. Not true. Teaching is his life. He says he loves his students, loves education and learning and watching young minds awaken. Problem is, he is seeing much less of it. It's a bit like the melting of the polar ice caps. Sure, there's been alarmist data about it for years, but until you see it for yourself, the deep visceral dread doesn't really hit home.
      He cites studies, reports, hard data, from the appalling effects of television on child brain development (i.e.; any TV exposure before 6 years old and your kid's basic cognitive wiring and spatial perceptions are pretty much scrambled for life), to the fact that, because of all the insidious mandatory testing teachers are now forced to incorporate into the curriculum, of the 182 school days in a year, there are 110 when such testing is going on somewhere at Oakland High. As one of his colleagues put it, "It's like weighing a calf twice a day, but never feeding it."
      But most of all, he simply observes his students, year to year, noting all the obvious evidence of teens' decreasing abilities when confronted with even the most basic intellectual tasks, from understanding simple history to working through moderately complex ideas to even (in a couple recent examples that particularly distressed him) being able to define the words "agriculture," or even "democracy." Not a single student could do it.
      It gets worse. My friend cites the fact that, of the 6,000 high school students he estimates he's taught over the span of his career, only a small fraction now make it to his grade with a functioning understanding of written English. They do not know how to form a sentence. They cannot write an intelligible paragraph. Recently, after giving an assignment that required drawing lines, he realized that not a single student actually knew how to use a ruler.
      It is, in short, nothing less than a tidal wave of dumb, with once-passionate, increasingly exasperated teachers like my friend nearly powerless to stop it. The worst part: It's not the kids' fault. They're merely the victims of a horribly failed educational system.
      Then our discussion often turns to the meat of it, the bigger picture, the ugly and unavoidable truism about the lack of need among the government and the power elite in this nation to create a truly effective educational system, one that actually generates intelligent, thoughtful, articulate citizens.
      Hell, why should they? After all, the dumber the populace, the easier it is to rule and control and launch unwinnable wars and pass laws telling them that sex is bad and TV is good and God knows all, so just pipe down and eat your Taco Bell Double-Supremo Burrito and be glad we don't arrest you for posting dirty pictures on your cute little blog.
      This is about when I try to offer counterevidence, a bit of optimism. For one thing, I've argued generational relativity in this space before, suggesting maybe kids are no scarier or dumber or more dangerous than they've ever been, and that maybe some of the problem is merely the same old awkward generation gap, with every current generation absolutely convinced the subsequent one is terrifically stupid and malicious and will be the end of society as a whole. Just the way it always seems.
      I also point out how, despite all the evidence of total public-education meltdown, I keep being surprised, keep hearing from/about teens and youth movements and actions that impress the hell out of me. Damn kids made the Internet what it is today, fer chrissakes. Revolutionized media. Broke all the rules. Still are.
      Hell, some of the best designers, writers, artists, poets, chefs, and so on that I meet are in their early to mid-20s. And the nation's top universities are still managing, despite a factory-churning mentality, to crank out young minds of astonishing ability and acumen. How did these kids do it? How did they escape the horrible public school system? How did they avoid the great dumbing down of America? Did they never see a TV show until they hit puberty? Were they all born and raised elsewhere, in India and Asia and Russia? Did they all go to Waldorf or Montessori and eat whole-grain breads and play with firecrackers and take long walks in wild nature? Are these kids flukes? Exceptions? Just lucky?
      My friend would say, well, yes, that's precisely what most of them are. Lucky, wealthy, foreign-born, private-schooled ... and increasingly rare. Most affluent parents in America - and many more who aren't - now put their kids in private schools from day one, and the smart ones give their kids no TV and minimal junk food and no video games. (Of course, this in no way guarantees a smart, attuned kid, but compared to the odds of success in the public school system, it sure seems to help). This covers about, what, 3 percent of the populace?
      As for the rest, well, the dystopian evidence seems overwhelming indeed, to the point where it might be no stretch at all to say the biggest threat facing America is perhaps not global warming, not perpetual warmongering, not garbage food or low-level radiation or way too much Lindsay Lohan, but a populace far too ignorant to know how to properly manage any of it, much less change it all for the better.
      What, too fatalistic? Don't worry. Soon enough, no one will know what the word even means.

    The railroads were slow to adopt roller bearings on freight cars because the cars were exchanged all over the country so the cars were paid for by one road but benefited other roads. They used to say these cars with roller bearings would only come back to the owners road when it needed repair so others were getting the benefit of the bearings they paid for. The early use of the roller bearing cars were usually in business where one road controlled the cars from shipper to customer so they always had conrtol of the cars.

    I replaced the turbo on my Subaru WRX from a TD04 journal bearing style to a VF34 roller bearing type. The VF34 being a much larger turbo would normally mean the turbo kicks in at a higher rev range but due to the roller bearing the turbo kicks in earlier giving the car turbo boost from just above idle all the way to 6000 RPM. Roller bearings just work.

The kind of material those old bushings were made of is actually a soft material made from copper and brass fiber mixture.

    SKF was not the first - older ball bearings were invented in Sundsvall, Sweden: "The most valuable object we have in the museum"
    SKF, the Swedish Kullagerfabriken, was one of the companies that brought Sweden into the industrial age and prosperity at the beginning of the 20th century.
    All school children have had to learn that. But before SKF in Gothenburg, ball bearings were built in Sundsvall, of which probably only one copy remains. You can see that in the museum on Norra berget. Bredenberg's ball bearings were single-row and not mobile enough.
    Where Bredenberg got the idea from is unknown, but he enlisted a talented Sundsvall mechanic, fabricator Aron Andersson, to help with the practicalities.
    From the beginning, the balls were turned one by one, so mass production was out of the question. Bredenberg took out a patent for his invention in 1890, and later that year another patent for an improved variant, where the bearing was "specially intended for railway carriages". In 1891 he gathered stakeholders into "Aktiebolaget Kullager", and the following year began commercial production in factory premises where Emhart Glass is now located.
    Bredenberg experimented further and displayed his product at the Landtbruksmötet in Gothenburg where he received first prize. But already in 1893 the company went bankrupt.
    - His ball bearing was single-row and not mobile enough, says Jürgen Holoch.
    Sven Wingquist, who invented the bearing on which SKF was built, was multi-row and thus more mobile. The few ball bearings that Bredenberg managed to sell also did not hold too much load and therefore broke. When SKF started its production in 1907, they used Hoforsstål, the best known at the time, and could make more durable bearings
    The ball bearing that the Antiquities Association displays in the Craft and Maritime Museum on Norra Berget was donated to the association by a manager of Wallerstedt in the 1930s. As far as the association knows, it is the only thing from Bredenberg's production that has been preserved.
    - It was one of the first ball bearings made, and not even SKF has one. I think it is the most valuable item we have, says Jürgen Holoch.

      There's a machine standing in the museum of FAG Kugelfischer in Schweinfurt, Germany that is claimed to be the very first machine for mass producing precision steel balls for ball bearings.
      I do suppose though that the idea and invention of ball bearings and their manufacture happened more or less at the same time spontaneously around the world given the profound advantages this technology offered countries aspiring to industrialisation.

    I used to work as an engineer for a few years for a bearing manufacturer. Although the designs and manufacturing technologies haven't change much since this footage was made, the material technology has advance a long way. In most cases manufacturers have their own secret recipes for their product alloys, usually a mixture of steel, nickel, chrome, manganese and other metals, which have increased the product's life expectancy.
    BTW, the bearings with the longest life expectancy, they last theoretically forever, don't have any rollers or balls. These are used in the huge generators in power plants and swim on an oil film that is continually pumped under huge pressure between the shaft and the outer race. The friction is allegedly as good as non-existent.

      The rails need to be absolutely level as the slightest incline will have a vertical force component of high value, way beyond human exertion.As the loco is in a perfect level postion the only resistive force is in the horizontal direction. As these loco use amazing anti-friction bearings the minimal contact surfaces of the balls and rods in the bearings make it possible to move such weights. Also, they incorporate lubricants into the bearing which reduces further adhesive wear. I researched wear as my thesis. So bearings keep surface contact to a minimal, and the grease or oil makes sliding much easier, so a heavy object can be move, only on flat ground. The slightest vertical angle of movement introduces gravity affect and easily exceeds human strength.

    I was skeptical of the girls pulling the locomotive, so I did some homework and the simple arithmetic:
    • the rail industry states that it takes 2 to 3 pounds per ton of "train weight" to start and/or move at slow, switch-yard speeds.
    • the NYC 4-8-4 "Niagara" weighed 236 tons.
    • so the four girls need to be capable of pulling with 236 * 2 = 472 pounds, or just 118 pounds of force each!
    The salient point to the whole thing winds up being the bearing surface of the wheels on the rails.
    Without that low-friction starting point, you could have frictionless magneto-hydraulic bearings and the train wouldn't budge a millimeter.
    Try it with a truck with 1/10th of the weight on rubber tires, it won't move without a lot more force.

      Locomotives themselves aren't that efficient. The statistic you're paraphrasing is actually _payload ton_ miles per gallon, which can reach such high numbers because of the enormous loads a freight train can haul and the low rolling resistance of steel wheels.
      I mean, it's not like the railroads have exclusive access to -magical- premium bearings that semi trucks do not have.

    Railroads weren't initially interested in roller bearings. Timken had to actually buy a new steam locomotive and outfit it with bearings because no RR would retrofit one to try out roller bearings.

    Most freight cars had plain bearings until the 1960s.

      In the UK such wagons were in use until the 1980s, but these wagons had low speed limits. Typically they weren't fitted with automatic brakes and were limited to 25mph.

      The reason for eliminating plain bearings on interchange cars had little to do with "roller freight" efficiency -- above about 3mph a good hydrodynamic plain bearing is just as effective; in fact, very few IC engines use rollers for critically-loaded parts like crank and big-end bearings.
      The switch was made for maintenance and reliability: any concerns with rolling wear were constrained to the bearing, and they could be grease-lubricated (as in AP bearings under the M-947 standard) to run longer than the lifetime of the steel wheels themselves.

    When Mr. Smith got pulled over for speeding, bearings wouldn't get him out of a ticket, but greasing the palm of the officer would.

    I want a vacuum that does over 3,000 RPM🤣🤣... I have cats and dogs lol they don't make them like they used to, I'm talking about the vacuum!

      Take your pick. I don’t know of a single modern day vacuum cleaner that’s not well over 3,000 rpm. Dyson V10 does 125,000 rpm.

      Vacuums have always been some of the highest rpm appliances, that's why they scream noise. Hair clogs everything, I use a shop vac on the dog, and he loves it. The cat, doesn't.

      Rail transport is very efficient, each boxcar = 5 truckloads. The truck and car are just faster, point to point. Bad air is the price for that speed.
