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

Isn’t that 10 microns? 0.01mm?
Which is 0.4 thou
Oh haha, yeah, I understand my error now. Thanks for bearing with me
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.

Thanks, I understand my error now. Corrected
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 !!!
