Tesla is facing issues with the bare metal construction of the Cybertruck, which Elon Musk warned was as tricky to do as making Lego bricks

    It’s almost like he hears about how bad the build quality of Tesla cars have become, so he thinks the solution is more accurrate, more expensive parts. Kind of like he has absolutely no clue what he’s doing, and doesn’t want to listen to smarter people telling him what they need.

      I think it’s more likely that he is looking for excuses for the years of delays on the cyber truck.

      Now he can blame it on his “desire for perfection” instead of admitting that his timeline was never viable

        The design isn’t viable. They could have developed a new car in less time if it wasn’t going to be an absolute nightmare to produce reliably.

          Let’s not forget about the new Roadster that was due to enter production 3 years ago.
          Everyone that bought one gave Tesla a $250k interest-free loan.

          This is all starting to seem intentional.

            At some point, once consumer rights are eroded enough , the straightest path to profits is just downright theft. Take money now, worry about product later. It’s literally inevitable and the video game industry is really fuckin good at it.

    10 microns is .4 thou, about the width of a cotton fiber. Its possible to machine those tolerances, but very time consuming as machine maintainance steps up. Its also small enough that the thermal expansion of the sheets will be larger than that

      Which just shows he has no idea how tolerances work. Small machined parts have different tolerances than large stamped parts. The key is setting the right tolerances for each part, designing the vehicle for desired gaps with those tolerances, and continuous improvement to fix and design out issues.

        None at all. He also doesn’t understend that the issues tesla has faced are largely due to poor process design rather than automotive design. The plans may call for small gaps ore big gaps, but they certainly don’t call for iconsistent gaps

      So basically elon would rather dump money into expensive equipment to improve build quality than do the thing that’s actually needed to improve build quality and pay his workers what their work is worth and make their factory environment safer?

      This is the kind of petty angry bullshit you have to do to be a billionaire. Its not about being smart, it’s about on some level hating everyone that isn’t you

        You aren’t going to hit that tolerance consistently on an assembly line no matter how much you pay. Can be done by a skilled machinist, but there are too many dynamical variables in an assembly line environment, like the previously mentioned thermal expansion.

          For reference, in working with parts that interface directly with optical components about the tightest I’m ever comfortable specifying at production volumes is 0.05mm and that is for very specific dimensions and not entire parts yet he is demanding 5 times lower tolerances here.

            It’s not even about that. You absolutely don’t need those tolerances for a cup holder. An assembly line will fuck it up regardless. You use tolerances like that when needed - in jet engines or turbines. Insisting on those numbers on a car is plain stupid - it isn’t better (other than the ego boosting “my car has high tolerances where nobody cares”) than just doing it like every other manufacturer does it. It’s a waste of money plain and simple.

        What I meant is that Elon has set a fairly un-achievable standard, as the sheet metal parts he is talking about will grow and shrink by more than that depending on weather. Additionaly, the small parts can be machined to that tolerance, but only by a skilled machinist and not at assembly line levels.

          Besides just thermal expansion, which will totally happen by driving on the road, the rotation of the motors and the use of brakes.

          It will also flex as it hits bumps and takes turns.

          And these will be different metals. With different thicknesses which will expand and contract at different rates.

        Making a lot of assumptions about what he’s willing to put into this.

        He’s not going to get fancy expensive new equipment, he’s not going to hire the best machinists, he’s not going to slow the work down to allow that kind of accuracy. He’s going to bluster and shout and make demands without providing any way of actually achieving those demands. That’s what Elon does. He’s not an Engineer, he doesn’t design things, he doesn’t build things, he tells people who actually know what they’re doing to build something. Here, he’s just saying “Do better” without anything more, and expecting that to be enough because he doesn’t actually know shit about dick.

        Frankly the closest I’ve seen to evidence that Elon has ever actually designed anything is the eyesore that is the Cybertruck, because it absolutely looks like something that cretin would draw in crayon and demand be made a reality.

      Imagine measuring door panels on a granite block in a climate controlled room, and sending it off to the surface grinder for rework. 🤣 Or sending the frame off to get scraped. Truly, this is the most idiotic idea on the planet and it’s all because he didn’t care about tolerances early on. His self own has turned into whatever the hell this crap was.

      I can confirm this

      Machinist here.

      .004 ? That is exagerated but .0004 this is insane

      This is not a airplane engine !!!

    I know it’s supposed to make them sound good and might indeed be meant for leaking, but all I can think of is the demands on quality assurance and risks of failures down the road if such precision is paramount for the operation of the vehicle and assumed by the teams building it.

    So give me a less finicky vehicle, please, and leave that precision for devices not subject to highly varying road conditions at very high speeds and housing people.

    Just like Steve Jobs and every other “visionary” all he does is demand things, have his engineers and factory slaves do their thing, and then go on stage and act like he personally minted every single cybertruck by hand. Any asshole can do the job of a visionary, actually, being an asshole is the only required skill.

    Hilarious considering the panel gaps in all his other cars, dude is fucking insane. Unattainable standards don’t breed better work they breed exasperation and apathy.

    If Elon would have looked back, he would have seen that Delorean has already tried bare metal, and it’s nearly impossible to fix. Dent your truck? May as well paint it.

    I mean, Elon obviously doesn’t care about repairability, but the first few fender benders will result in a pile of articles about how unfixable the body panels actually are.
