The production of Lego and soda cans is undoubtedly an accurate analog to the mass production of passenger vehicles.

[–]SnipesCC 562 points563 points  (12 children)

To be fair, LEGO does produce the most tires of any manufacturer in the world

[–]Dildo___Schwaggins 128 points129 points  (1 child)

Maybe Lonny should contract them to be official tire supplier then? I mean if Lego can successfully mass produce tires for children's toys then I see no reason why they can't do the same for passenger vehicles?

[–]The-disgracist 39 points40 points  (4 children)

I think they make the most car “parts” too

    Just the welding and self piercing rivets alone would distort the metal 10x that much. How much do you think their suppliers will charge them for that accuracy? That is damn near gauge block tolerances. Could it be done? Sure, but it will take forever and cost a fucking fortune.

    EDIT: for one car.

    I do automation and I've worked at Tesla. Fuck the robots they use only have repeatability of +/-0.05mm or less, that is not the accuracy that is repeatability. Fuck just thermal expansion alone will throw that shit way off

    [–]3rdp0st 65 points66 points  (26 children)

    0.01mm is less than the thickness of the semiconductor active layers in the inverters even if they're using expensive SiC MOSFET/IGBT's and diodes. Dude is an idiot.

    [–]mechanicalsam 52 points53 points  (11 children)

    What's even funnier to me is how notorious Teslas are for improperly fitted body panels. Elon talking about micron tolerance when they can't even align body panels on their current production cars? What a tool.

    [–]Fakjbf 31 points32 points  (3 children)

    Honestly I think this is exactly what sparked the email. Elon knows their QC is shit and that his cars are known for having misaligned panels, so he wants to improve that. But he’s too incompetent to actually make improvements to the production process so he’s just telling people to try and attain ridiculous standards and hoping that works. Don’t actually give them any kind of support or increased funding to improve the production process, just tell people to be perfect and it’ll magically happen!

            I imagine working for Lego has to be pretty fucking stable. That shit is not going anywhere.

            Edit: to everyone who thinks they are clever pointing out Lego almost went under, ask how good your reading comprehension is. Am I talking about where they were, or where they are going? They are licensed to make Star Wars toys and Disney owns Star Wars now. Are they going anywhere? I don’t care, about where they were, its extremely stable now.

                        Just because I was curious. 81% of Lego employees would recommend working for Lego and their engineers actually make really good money. My friend has a software engineering degree with a speciality in AI from Purdue and doesn’t make what Lego engineers make.

                          See the irony of it is him thinking LEGO is cheap.

                          It's fairly cheap in absolute terms, because, well, it is made of literal plastic. But relative to other toys? Even other toys of a similar type? LEGO is pretty damn expensive and it's not all because they're licensing well-known brands—it's because of how damn rigorous their product has to be. New pieces have to fit ones that are decades old perfectly and be made with incredible precision and an incredibly low tolerance for defects (because a single serious defect can ruin an entire set).

                          It's ironic because it's kind of the exact opposite of Tesla. They actually put in the rigour and effort required to ensure a quality product.

                          [–]a_moniker 116 points117 points  (60 children)

                          LEGO is also insane about their tolerances. Each injection mold, for each brick, costs around $200,000 and lasts for around 1 month.

                          [–]wurstbrot_royal 45 points46 points  (49 children)

                          That's not necessarily true about their colors though. There's a German guy on Youtube who shows the bad sides of sets and how much of a rip-off they are, and he frequently shows that colors are mismatched in full color panels.

                          [–]TheBestIsaac 83 points84 points  (28 children)

                          That's just colours though. They fade and change and are very hard to get right every time and 99% of people won't even notice.

                          The sizes and shapes and tolerances are second to none. That's where they spend their money.

                          [–]CreationBlues 31 points32 points  (27 children)

                          Most people are just unaware of how complex colors are. Hell, most people don’t even know the difference between a dye and a pigment! (Dyes are soluble, pigments are insoluble)

                          Everything from subtle chemistry details to particle size to how they’re added to the base an fundamentally change the color.

                          And this is just one color! Once you start mixing pigments/dyes the complications compound exponentially. And then these mixtures start aging. Forget the difference between an old and new brick, even two bricks with different color batches of the same age that used to look identical will have their different formulations age in different directions!

                              The less-talked about thing that LEGO brings to the table is that they know exactly which 'systems' people to employ to keep their parts interoperability absolutely spot-on and futureproof.

                              I've grown up through the '80s and '90s playing with the stuff, and in the last few years bought some of those newer modular city buildings (bookstore, diner, etc.), which have insanely complicated details in them. There are parts in them that I recognise from my childhood from old space sets, and newer-designed ones that still clip on to them precisely, because there's seemingly a predetermined set of modular dimensions that guarantees everything can attach onto most other things in some way or other, even if not via the classic studs. I have no idea how they keep it going.

                              [–]ShouldersofGiants100 43 points44 points  (6 children)

                              There is a deep rabbit hole of LEGO rules and regulations that every single piece and set they release has to follow (mostly to prevent any piece from getting strain in a way it wasn't deliberately designed for). And of course, a lot of hobbyists who manage crazy shit by breaking those rules.

                              It's not even all that complicated once you know the terminology—it just requires a massive amount of quality control and a lot of people who are very good at what they do.

                                It’s a hell of a lot harder to maintain accuracy on a piece of metal, especially higher tensile strength metals. I’m not even sure what the minimum tolerance would be you could hold. I’m assuming the material is similar to what GM uses.

                                Aluminum is very pliable, different story.

                                Does anyone know if they stamp the panels out, or roll form them, or do it another way?

                                    he wants to play the engineer so badly but has no idea what he is ordering. not every component needs to have a ridiculously tiny tolerance (±0.010mm) for stupid arbitrary reasons about "peRfeCtiOn", which only increases fabrication costs unnecessarily. the actually qualified Tesla engineers will read this and completely ignore it

And before you say Musk is even a little smarter, I think a few more decades of yesmen and ketamine will make him as dumb as Trump by the time he's in his 70s.

                                    The real difference between them is Trump is actually funny.

                                          Came here for this.

                                          He's just proving that he doesn't know jack shit about engineering.

                                          GD&T is a lot more complicated that just saying "we need 10 micron accuracy." Is that for overall lengths? Flatness? Cylindricity? Somehow everything?

                                          He's just saying meaningless words based on things he's heard actual engineers say.

                                          It is even funnier that he doesn't even specify which part. This standard somehow applies to literally everything on the truck equally.

                                          Like the stitch length on the seatbelts needs to be exactly as precise as the bearings in the engines. For... reasons.

                                          He actually mentions the fact that it's for the look of the truck though. I think he's suggesting that the dimensional accuracy of the panels should be 10 microns. The panels!

                                          Probably not measurable to that level of precision in a manufacturing process to actually verify whether you have achieved it or not.

                                          And if you did, congratulations! Your truck just cost you $3 000 000 to manufacture

                                                Hilarious. The CTE of most stainless steels is above 1e-5 per degree C, so a meter-long body panel would be out of spec if the temperature changed 1 degree C.

                                                      I worked on a much smaller product than a fucking car and it had to be precision manufactured because it operated with static parts and dynamic parts together. We had many components that were machined to +/- 0.001 in and many times my dumb ass would put that shit on parts that definitely didn’t need that precision. Shop would always come back asking why tf this needs to be so accurate, engineering? There’s no fucking way every part of that truck ESPECIALLY cosmetic needs to be that accurate manufactured to look good.

                                                      The guys I worked with were some good machinists tho. Modern manufacturing is amazing. Or they lied on the inspection reports 😂

                                                      Over tolerancing is literally a thing that needs to be beat out of engineers sometimes. It also feels a bit disgusting sticking any bigger than like +-2 when in reality it would work at like +-20

                                                      Inspection: dimension is +6.3

                                                      Me: uhhh yeah it's fine

                                                      It usually gets hammered into them because the maching cost gets another zero or two added to the end for each digit of precision specified.

                                                      This is what Musk is showcasing he doesn't understand anything about engineering. The costs absolutely explode with precision.

                                                      Sub micron accuracy on a large metal part, you'd have to mention at what temperature it's measured at because it'd expand and contract more than that.

                                                      Lol I’ve let so much shit slide cuz I’d be like yeah that doesn’t need that much of a tolerance on it it’s just a static part hooking up to a customers static part, approved as-is. But man. If shit goes wrong in the field cuz of some thing I missed it’s my ass on the line they can’t install the part and now the machine run is delayed. There’s so much pressure on engineering we kinda over do things just to save our skin. Shop goes through 80 quality checks I get maybe one look over by my busy ass boss before it’s sent to manufacturing.

                                                      Anyway, I miss product design a lot even tho it’s stressful cuz it was still simpler than the shit I gotta handle now.

                                                          Actual engineers at spaceX. It's reasonable to build a spaceship to single micron accuracy, but not a consumer truck you want to sell for $40k. Now, every bolt and screw just became custom, and machine costs quadrupled. Can't wait to see the price when this rolls out.

                                                          Cybertruck will end up some bloated monstrosity of cost.

For some stupid reason, any dimension deemed critical was required to have GD&T, regardless whether or not it served the function of the part. OAL is critical? X +/- Y isn't sufficient, it must have GD&T.

                                                              No wonder the engineers just started slapping profile tolerances over the whole part.

                                                                  Nobody is sewing the seat upholstery to 10 microns of standards. That sort of precision literally doesn't exist in industrial sewing. Nobody is looking at doorhandles, radio knobs, and seatbelts for some bullshit tolerance it isn't needed.

                                                                  Sure, some parts on the Cyber-truck might need to be that precise, but applying it to the whole truck just screams "I have no idea what I am talking about".

The variance in a stainless steel hood would require measurements at a specific temperature. 30 minutes after entering a warmer or colder location, the size of large parts will be different.

                                                                  [–]ShinySpoon 41 points42 points  (12 children)

If LEGO's manufacturing process was that easy to match, wouldn't everyone be doing it?

So, he turned off the safety, stuck his head into the line, let it hit him, and got knocked silly.

He stridently strides over and places laser protractor on hood of a Cybertruck prototype and says: "Yes sir, absolutely sir!"

Most aircraft will include z-shaped kinks in any long tube so that it has a place to bend when it expands and contracts. 10 micron tolerance doesn’t matter too much when the bending an order of magnitude more.

He knows there are problems with the body panels fitting together, and rather than asking someone qualified to work up a solution, he’s too obsessed with himself to not be the one who solves it. And in the process he reveals that he knows absolutely nothing about materials.

Those harsh angles and in particular the flat front that seems designed to transfer as much force as possible? That will literally kill someone.

Some of the voluntary commitments he backed out of were enshrined in law and due to start rolling out by the end of the year. I doubt Twitter will still be available in the EU by 2024 and I think that might be the tipping point that kills it, because someone else is going to get ALL those users.

They'll hold up the entire submittal process with this type of stupid shit then blame me for causing delays. I'll usually cave and put what they want in a submittal just to get their signature then submit the actual design to the qualified engineering team for review. People like Elon are just PR clowns and have nothing to do with the actual fabrication process.

I can’t count the amount of times I’m having to explain to management/higher ups that tolerances below 30thou WILL take more time and cost way more than the customer was initially told(due to underbidding). Like large frames with lots of tapped holes all over, with some other things that were critical, had a blanket tolerance of 10thou. 80% of the holes on those frames ultimately got nothing more than a castor, or leveling screws, or rubber ‘bump stops’ thingys. Absolutely asinine to be 10 thou for that shit.

                                                                                                                                  Standard tolerancing for most things I make is plus or minus .005 inches, or a .01 inch window. They literally use the words "unless otherwise specified." By the way, most things I make are for aerospace research.

                                                                                                                                  Things get toleranced more tightly when they are more important. This requires more careful setup, in process checking, and a more stringent QA process to achieve/ensure. So they take more time and cost more $$$.

                                                                                                                                  So to ensure that parts get made quickly and cost less, a good engineer only uses tight tolerances when it's important. Making everything fit in a .0004 inch window is how you take a simple $100 part and make it a $5000 nightmare.

I'd always have to remind them that the plans they're looking at are usually based off of some muddy, underpaid geologist's hand written notes on engineering scale grid. Every map is an approximate model of reality, and to say otherwise could get us in legal trouble. Frikkin engineers.

                                                                                                                                                  In any case, there are very established industries that have been working with stainless steel for a long time, for example, the industrial kitchen furniture industry or appliances and machines for the food industry. And industrial stainless steel kitchen furniture is more expensive to produce for this reason (not counting material costs).

                                                                                                                                                  Many are medium-sized workshops, since they produce homogeneous finishes, a lot of quality control is needed per unit. (Stainless steel metalwork and professional finishing is serious business)

                                                                                                                                                  ps: the car has a steel/aluminum subframe with a stainless steel body/panels.

                                                                                                                                                  And obviously if the body of the chassis has brutal deviations (as it happens with Tesla models) they will be much more noticeable now with larger overall dimensions than the CiberMeme has.

                                                                                                                                                  All enhanced by the uniformity of its stainless steel finish. Misalignments or poor finishing and its peculiar geometry (angles) will be noticed much more.

                                                                                                                                                  And the homogeneity of finishes between units will be more crazy than it already is with the models that the brand has.

                                                                                                                                                  Not just on the exterior trim, all the fucking noises of that cars have is given to this. The bad measurements and tolerances and the adjustment of the cheap plastic and bad soundproofing are the main problem.

But if you try to place them in frames with deviations, they end up badly placed, too tight, etc... those deviations end up adding up.

                                                                                                                                                  That is why the automotive industry seeks above all homogeneity of all the elements of the car. Starting from the fact that each frame is sought to be 'perfect' and each supplier of the rest of the parts maintains the same standard without buts. (any changes to the model, for example chassis tolerances, can affect the entire supply chain).

                                                                                                                                                  ps2: sorry for this brick

                                                                                                                                                    I would say it's because he's not an engineer and doesn't understand manufacturing metal parts. As a software developer, I can attest to almost everything he says about the code at X makes no sense, and sounds like something a junior developer with no experience would say.

                                                                                                                                                    His entire career has been based on having engineers do things for him. Steve Jobs was like this, but was very open about the fact that he wasn't the one building the things.

                                                                                                                                                            it is now 16 years later and he is just now talking about the possible batteries in the upcoming years, which tells me he purposefully delayed technology by over a decade to feed his own ego.

Super tight tolerances on things that are completely arbitrary. All this does is make things take longer and cost more. A Lego block is one thing. A fucking vehicle with a million parts is just absurd. As a super mega ultra genius Elon should know this. EVERY part has to be sub 10 micron tolerance??? It's a Tesla dude. Im sure that dumbass crypto bro is gonna notice the bolt on his door hinge is off by .001. This email is more evidence that he just loves to sound like he knows what he's talking about and can't help but fellate himself every chance he gets. If Elon tried designing a drawing for a part I had to make I would have a fucking aneurysm. It would also probably be impossible to make because he's a moron that likely doesn't even know how a lathe or a mill works. The only explanation for this email other than him being a drug addled lunatic is he never actually wants the Cyber Truck to be made.

He’s not going to address how those parts are made, he’s just going to use more decimal places in drawings? Not to mention that manufacturing cars to that level of precision would make them ludicrously expensive.

                                                                                                                                                            This type of direction should never come from the CEO or the owner of a company, properly toleranced parts require the volition of a single qualified person, and the objective scrutiny of peer revie by other qualified people, to qualify that engineer's choices.

                                                                                                                                                            any sort of blanket direction on precision as it applies to tolerance is just plain stupid; 100% stupid, as in you cannot hammer open the concept of precision and expect to deliver perfection, the two concepts are inversely related: the more precise your dimensions, the more difficult it is to achieve them. Perfection might as well be a literal unicorn 🦄, because it's a fantasy.

He's going to make that ugly thing cost 10x as much. I used to work for a place that made parts for SpaceX and they were impossible to work with. They'd specify one tolerance then kick back things that didn't meet a tighter tolerance. Now I fully believe they did that on purpose to avoid the more expensive cost of tighter tolerances.
