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
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
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.
It’s design demonstrates a fundamental misunderstanding of what trucks are for. I know people give the CEO of Ford shit for saying hes not worried about the Cybertruck because people who want to do real work wouldn’t take any interest in it, but its true. Trucks all have the shape of bed they do for a reason. Convergent product evolution landed on that as the best shape for a bed for trailer hitches
Harsh, but fair 😂
Reminds me of Bill Burr https://youtu.be/E3s-qZsjK8I?si=YKykzYsFt7lnPC6g
I love the uncomfortable silence. He makes really good use of it too. I’ve seen him do that several times and it’s always hilarious to me.

Lol, never saw that bit before. Bill Burr is an absolute treasure.
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.
I guess they could do like Nissan did with the GTR’s engine: climate controlled assembly bay, temperature check on the parts etc…
But I mean, they did it only for the engine which is relatively small
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.
I can confirm this
Machinist here.
.004 ? That is exagerated but .0004 this is insane
This is not a airplane engine !!!
0.4 thou = 0.01mm
0.4 thou = 0.4 mil
(TIL about thous, all my engineering textbooks referencing US units must be old or something)
decimal inches is basically only used in machining. The only time ive ever seen it is in schematics and an indicators.
Isn’t that 10 microns? 0.01mm?
Which is 0.4 thou
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.
