It's the dunk tank.

This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.

Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.

Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.

Rule 3: No sectarianism.

Rule 4: TERF/SWERFs Not Welcome

Rule 5: No ableism of any kind (that includes stuff like libt*rd)

Rule 6: Do not post fellow hexbears.

Rule 7: Do not individually target other instances' admins or moderators.

Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this. Posts that do not meet this requirement can be posted to [email protected]

Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

If your're such a fucken genius why don't you just make the cars out of lego and beer cans then? Ever think of that ya fucken knob?

Given that teslas have notoriously bad tolerances, like gaps on the order of millimeters, ya might want to fix the cause of that first lol.

This is how "entrepreneurs" "innovate". They just say they want something and everybody else tries to work around the roadblocks the CEO probably put in place that make achieving the goal way harder than necessary.

I like how he explains what a micron is as if the people who actually build things at Tesla don't know

and honestly a little jankiness will just contribute to the PS1 aesthetic, he should want to lean into it for meme marketing purposes

It really does take a genius and visionary to sit back and say "Hey, guys, let's make this, but with as small an error as I can imagine. Don't like, assess how precise stuff needs to be or consider any of that. Just make it all like really, unreasonably well, okay?"

I'm sure the engineers are blown away by that big mind, what a privilege. It reads like an excuse to blame the engineers when the truck inevitably sucks because they didn't follow his perfect design.

[–] [email protected] 39 points 1 year ago* (last edited 1 year ago)

Yeah I hate those fake appeals to "genius". To the extent that someone like Musk provides "guidance" at all, it is to merely hop on his email and say some Captain Obvious shit to thousands of people who are too busy doing real work to read that shit.

Bourgeois apologists always deny the theft of surplus values from the workers and insist that profit is merely the boss's "wages" for his "unique labor" of "training, guidance, and planning".

But most of the actual training, guidance, and planning is not done by the actual owners, but by managers, who are employees that are paid a high salary, but are not usually board members or share holders or other bourgeoisie who live primarily off of surplus value.

He's known for flipping the fuck out on anyone at anytime for any reason. I worked with a number of people who came from Tesla and they had endless horror stories about him. Basically you just pray never to run into him and if you do, try your best not to get noticed or you might end up losing your job that day just because he likes to instill fear and make himself feel big by firing people for any or no real reason.

I used to work for a company that made stamping dies for aluminum cans, and some of those dies had tolerances close to .0004", because the aluminum is very thin and could crack and tear if the dies were not made precisely. The cans themselves are not that precise, they just need to hold beer without exploding. I can't speak to Legos, but cars absolutely do not need this kind of precision, not even in the bearings. And especially not in the sheet metal body panels.

[–] [email protected] 28 points 1 year ago (1 children)

I can't speak to Legos

Legos famously have a weirdly high tolerance for injected molded plastic*, it's part of the branding they use to justify their high price. It does make them snap together more reliably than Mega Blocks or whatever, but Mega Blocks or whatever usually snap together anyway, so I don't know whether that extra precision counts as necessary.

* People quote all sorts of tolerances for this, but the most credible-looking one I found was 0.04 mm.

Critical support for melon-musk demanding sub-human hair tolerances for the panels of that shitbox. I'm sure you will get it done for a bargain.

[–] [email protected] 75 points 1 year ago (1 children)

Teslas, famous for their tight tolerances.

[–] [email protected] 94 points 1 year ago* (last edited 1 year ago) (1 children)

Elon heard that there's tolerance in manufacturing and his apartheid brain went "not on my watch!"

[–] [email protected] 71 points 1 year ago (1 children)

Listen everyone: just make the parts perfect. All of them. You know how it hasn't been perfect so far? Yeah that sucks, do it perfectly instead.

I've used waterjet, CNC, and EDM parts. The waterjets typically give me ~100 micron accuracy, CNC ~20 micron and EDM ~10 micron.

Make the tolerances too tight and the body parts will interact with each other in unfortunate ways - shell gets too hot, metal expands, and you can't open or close the doors. Window glass will crack etc.

Watch these fucking life-size HotWheels fly apart when it gets too cold or too hot.

[–] [email protected] 26 points 1 year ago (1 children)

It's funny how Tesla's already have a reputation for being designed with only California weather in mind, and now he plans on making them even more susceptible to such foreign concepts as "cold" and "heat".

Precision predicates perfectionism

Perfectionism is seen as a counterproductive and bad thing most of the time. Someone should tell King Bazinga that, if only there was someone around him that wasn't afraid for their job.

[–] [email protected] 45 points 1 year ago

The 80/20 principle is where you work 80 hours on the weekdays and 20 hours on the weekends because we need to get this out perfect and also yesterday.

[–] [email protected] 42 points 1 year ago* (last edited 1 year ago) (1 children)

yea nah. I doubt anything outside of the electronics requires that tolerance. Including any of the bearings. The finest grade of sand is about 62 microns. LEGO and soda cans do not adhere to those tolerances. 100 microns maybe.

I must have confused the cybertruck with one of my rocket engines.

these comments are pretty fun

Lol at comparing an entire assembled truck to a soda can. Elon is going to get replaced as the richest person in the world by the guy who resells scrap metal from Tesla factories.

Any fanboi that can read this and still defend Musk's genius deserves to be shot.

"tolerances need to be specified in single digit microns" technically precludes any tolerance being specified smaller than 1u, so that will be fun for the electronics.

Hahahahahahaha, look, any large production at scale is usually going to be at least .001 inches out of tolerance, especially anything that has to be cut in mass at rate, either that or he is going to be fine if a cnc or water jet guy has to recalibrate his entire machine and probably trash one to two pieces after about the first five years making these things, either that or buy a new one or constantly be replacing parts. Like, it is so rare to ever have anything like that kind of tolerance. It is can be accomplished, for small plastic and light light metals constructions, but large vehicles? It's possible but idk if you will ever really make a profit or be able to produce it quickly.

But I suppose, his wealth rides more on notoriety and finance capital than actual production, but come on man, you just got Tesla in the black (not it wouldn't take like 30 years of unprecedented Chinese level growth to produce manufacturing products that actually pay back the amount of money that was lent out towards to it), why are you fucking with this thing? Everyone knows your cars are shit, nobody cares, you're the Apple of cars, just be happy and make money. These idiots will buy whatever slop you sell, just put it out as fast as possible at the very height of the price-demand curve.

Edit: With how this whole thing was reported and marketed, I really think that Elon is responsible for this one, his fans eat this shit for breakfast.

I can't wait for Teslas workers handling multiple, frequently calibrated high-precision micrometers from different high-end manufacturers and taking multiple measurements and averaging them to get a result.

Because that's how LEGO does it.

[–] [email protected] 30 points 1 year ago

Lego also has to only check the tolerances of molds and replace them when needed, with car you'll have to check them in thousands of different places and steps of the manufacturing and assembly with compounding errors

Elmo seriously sent that to everyone in the company? When that information was maybe relevant to a handful of people?

[–] [email protected] 49 points 1 year ago (2 children)

That information is relevant to zero people because it's impossible to make anything out of bent sheet metal with a .0004" tolerance. He may as well have asked for a working car made out of cheese.

tbh I can't debunk any of that, but it wouldn't surprise me if he's tripling the cost of parts that are just going to get smashed into a pole after Full Self-Driving over a crowded crosswalk.

For this to work I'd assume he'd need to invest in gear that can test precision within that range, so nothing will happen
