I bet we can make a pretty good guess on that, and the last names weren't "Smith" or "Weber"

@Wolffkran when their cars stop working, it's evil gremlins, not that they haven't been doing routine maintenance for half a decade.

@Wolffkran because people don't know how shit works

@sickburnbro Yeah I was also extremely confused why people blamed the pilots for this

The whole idea of that sub was fucked up and unsafe from the get go. Shoddy manufacturing like making the carbon fiber section not in a clean room was just icing on the cake.

@BroDrillard @chud @Heil_Honkler speaking of the "managers that are excited that they can get indian developers for 20/hr " ..

@sickburnbro oh shit, so it wasn't pilot error. fucking monkeys with wrenches.

Like the brown people they hired to do maintenance on that Titanic sub that imploded a few years back. Tightening bolts with non-torque wrenches by hand for a sub meant to go more than 2 miles underwater

@BroDrillard @chud @Heil_Honkler like dog, I wouldn't trust a mechanic to work on my car that was making less than 50.

@sickburnbro @BroDrillard @chud @Heil_Honkler Only shops that aren't cutting corners at <$50/Hr are quick lubes, and even then I don't trust them.

@christmasman @BroDrillard @chud @Heil_Honkler indeed. the lubrication system in your car is the most critical. if you don't tighten a plug and the oil runs out at highway speeds, you're quite possibly fucked, and they will disclaim all responsibility.

@BroDrillard @wingedhussar @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler you don't need titanium for a sub though? steel is pretty good under compression, iirc

>Forging and machining a titanium tube would have cost a fortune and it'd require expensive foam for buoyancy.
Dying was cheaper.

@Snidely_Whiplash @BroDrillard @chud @Heil_Honkler @sickburnbro The billionaire was an aerospace guy, so he wanted carbon fiber, ignoring the fact that the loads on a submarine are the opposite of those on an aircraft

@Dr_Edgar_Friendly_MD @Snidely_Whiplash @BroDrillard @chud @Heil_Honkler @sickburnbro He wanted carbon fiber because he got his hands on declassified documents for a composite submersible the navy built and a buttload of expired prepreg CF from Boeing. Forging and machining a titanium tube would have cost a fortune and it'd require expensive foam for buoyancy.

Carbon fiber on a sub, why? To save weight? It's a submarine. Metals get stronger with compression and working. Resin plastics get weaker. Each dive made the next dive less safe.
The entire concept was fucked.

@wingedhussar @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler a front and rear ballast should kinda fix that, no?

Embed this notice
@sickburnbro @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler Its too heavy. It'd sink without ballast

@wingedhussar @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler but yeah, I mean I guess it makes propulsion trickier as well? Oh well. I guess they learned the hard way that the sea doesn't care

@wingedhussar @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler right, so they basically just thought they had a cheat code to submersibles
-
Embed this notice
@sickburnbro @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler Yeah but the amount of syntatic foam would be huge. Most submersibles are made from forged titanium

@wingedhussar @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler Oh, I know - I don't like composites for that exact reason.

@sickburnbro @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler Its not unbased. The navy did successfully build a reliable and safe composite sub that went deeper than the Titanic. However:
1. They had endless government money
2. They had navy yard resources
3. Composites are unpredictable and do not yield like steels do.
My favorite part of all this is that they broke every rule and somehow nature didn't spite them. The hull held. They then ignored their own patented hull strain monitoring system that told them theyre has been a significant structural failure. The hull survived 1 more dive after that. The 2nd one it imploded.

@sickburnbro @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler The navy abandoned the project for those reasons. It was like...yeah it held but we don't know when it won't. Metals are predictable and handle load cycling well if everything is properly engineered.

@Elliptica @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @wingedhussar it's why youtube is still a good thing - you can gain an appreciation for how technically difficult creating threads are. For standard threads, someone's already done the hard work once, and people just need to ensure the tooling doesn't wear out

@BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @sickburnbro @wingedhussar I had a realization like that once. I have an expensive camera that I wanted to attach to a telescope, but the telescope used a weird nonstandard connector. I found a guy in Florida would would make an adapter to a more standard connector, but he wanted, like, 100 dollars for a part that for a standard size would cost less than 10 (its basically just a metal ring). I managed to find someone else selling an adapter for around that price, but when I actually got it, it was really bad. I had a realization that, yeah, the camera costs ways more than 100 dollars, and if this cheap part broke I'd be really depressed, so I shouldn't cheap out here.

@Elliptica @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @wingedhussar yeah, I saw a video of a guy literally friction welding a fairly large part because he didn't properly clean the threads.

@sickburnbro @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @wingedhussar Yeah, I had to take a metal working class in college, so I sort of thought "whats the big deal?" But we never made a big threaded part, just like screws and stuff like that.

@sickburnbro @Elliptica @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @wingedhussar That's pretty cool, though. Probably how friction welding was discovered.

@petra @Elliptica @BroDrillard @Snidely_Whiplash @chud @Dr_Edgar_Friendly_MD @Heil_Honkler @wingedhussar what is the most impressive part is how much friction you can generate with threading. it makes sense when you think about how much can torque two parts together, but just not something you really think about "how that works"
