Part 2I Can Fix This Hunk of Metal—The Boss Bet His Life on It

I walked a slow circle around the DMG machine, like I was inspecting a long-lost friend. The others had dispersed, returning to their workstations, but I could feel their eyes on me, their ears tuned in, all waiting to see the "clown" in the corner make a fool of himself.

Lisa hadn't left. She stood a short distance away, arms crossed, her face a mask of undisguised skepticism and curiosity.

“I need a toolset,” I said to her.

She raised an eyebrow. “What kind of tools? The stockroom is full of them. Go get them yourself.”

I shook my head and recited a string of German words.

“Eine komplette Garnitur von der Hoffmann Group, Drehmomentschlüssel, Satz Feinmessschrauben…”

Lisa’s expression froze. She only understood bits and pieces, but the authentic German pronunciation chipped away at the disdain on her face.

“What did you say?”

I switched back to English, patiently repeating myself. “A German-made Hoffmann Group toolset. Sixteen-piece socket set, a torque wrench, and a set of precision micrometers. They were bought with the machine when the factory was set up. Should be in a silver metal case.”

The shop foreman, a jaded old-timer named Dave, let out a snort. “Hey, Carter, who do you think you are? You think you know where everything is? We don’t have anything like that here.”

“You do,” I said calmly. “It’s in the stockroom, second row of shelves, third box from the top. It should have a label on it that says ‘Ersatzteile’.”

Dave’s face changed. “Ersatzteile” was German for “spare parts.” The label was there, but almost no one in the factory knew what it meant.

Lisa’s eyes lit up. She turned to the foreman. “Dave, go have a look.”

Dave, muttering about how I was just guessing, took two workers and headed to the stockroom. A few minutes later, the three of them returned, carrying a dusty silver metal case, their faces etched with astonishment.

They opened the case. Inside, nestled in red velvet lining, was a brand-new set of German tools, gleaming with a metallic sheen, the protective oil still slick on their surfaces.

Dave’s face went from red to white and back again. A few hushed gasps rippled through the onlookers.

The way Lisa looked at me had completely changed.

I paid them no mind. I put on a pair of reading glasses I’d pulled from my pocket and took a long, thin metal rod from the case—a mechanic’s stethoscope.

I didn’t open a single electrical cabinet or connect any diagnostic equipment.

I gently placed one end of the rod against the machine’s main spindle housing. Then, I bent down and pressed the other end firmly to my ear.

I closed my eyes.

The gesture was like a seasoned old doctor listening to a chronically ill patient.

“Heh, what a showoff. Who does he think he’s fooling?” a young worker whispered.

“Yeah, thinks he’s some kind of machine whisperer? He’s going to diagnose it just by listening?”

Lisa frowned, clearly baffled by what I was doing.

I heard none of it. My world had shrunk to just me and this machine.

I could hear the subtle sounds from within.

The almost imperceptible, abnormal friction between the gears.

The minuscule, jerky hesitation as the guide rails slid.

The faint popping of air bubbles in a specific point of the lubrication line.

To anyone else, it was just noise. To me, it was a detailed diagnostic report, clear as day.

For a full ten minutes, I didn't move.

Then, I straightened up and took off my glasses.

I reached out with my rough hands and, as if stroking a lover’s skin, ran my fingertips over the cold seams of the guide rails, again and again. My fingers could feel the microscopic misalignments and wear, measured in microns.

“Well?” Lisa finally broke the silence. Her voice had lost its earlier contempt, replaced now by sheer bewilderment.

I turned to face her, and to face Rick and the other workers who had gathered around again.

I announced my diagnosis.

“It’s not an electrical problem.”

“It’s the machine’s XY-axis drive module. It took a hard impact during shipping or installation, causing an irreversible loss of mechanical precision.”

“My initial estimate is a deviation of at least 50 microns.”

The statement hit the workshop like a bomb.

Lisa’s eyes went wide. She rushed over to a nearby desk, rummaged through a pile of papers, and pulled out a report, holding it up to me.

“But… but the diagnostic report from those eight experts concluded it was a ‘main control chip overload and burnout, drive circuit board failure, recommend complete replacement of the motherboard and servo system’!”

On the report, the words “Main Control Chip Failure” were in bold red, followed by a shocking repair quote—one hundred and fifty thousand dollars.

My eyes scanned the report, and a cold smile touched my lips.

“They were wrong.”

“How can you be so sure?” Lisa pressed, her voice urgent.

I pointed to an inconspicuous hex bolt on the machine’s base. “This bolt is one of the reference points for leveling the machine at the factory. Its torque specification is incredibly strict, with a tolerance of less than 0.1 Newton-meters.”

I gave the bolt a gentle twist with my fingers.

“But the torque on this bolt is wrong. It’s been re-tightened.”

“And by an amateur. Not only did they fail to recalibrate it, but they also destroyed the stress balance of the entire base that was set at the factory.”

“That’s the real source of the precision loss.”

“As for the electrical alarms,” I paused, “that’s just the system’s self-preservation kicking in. The mechanical error is causing the servo motors to overload.”

The workshop was utterly silent.

Everyone was staring at me as if I were some kind of alien. A stockroom manager, using only his ears and hands, had just refuted the conclusions of eight professors armed with sophisticated instruments. It was unbelievable.

Rick’s face was a storm of conflicting emotions—doubt and shock warring for dominance.

Lisa was completely floored. The last traces of disdain in her eyes had vanished, replaced by a profound, undisguised astonishment and intense curiosity.

“Talk is cheap,” Rick said, his face grim, breaking the silence. “You said you can fix it, so fix it. I don’t care if you heard it or felt it. I just want results.”

“Alright.”

I said nothing more. I took off my outer shirt, leaving me in a gray, worn-out tank top.

From the new Hoffmann toolset, I selected a few oddly shaped instruments.

With no blueprints, no repair manual, I began to disassemble the machine’s core drive system.

My every movement had a strange, fluid rhythm.

Which screw to loosen, with how much force.

Which component to remove, in what order.

It was all as if I had practiced it a thousand times, the motions ingrained in my muscle memory. My hands, those calloused and scarred hands, moved with the grace of a dancer.

The crowd of workers, who had initially been watching for entertainment, fell silent.

“Look at him, pretending he knows what he’s doing. It’ll be hilarious when he can’t put it back together.”

“Yeah, this is German engineering. You can’t just mess with it without a manual. He’s asking for trouble.”

But gradually, the snickering stopped. Everyone held their tongue, their expressions shifting from amusement to silence, then to surprise, and finally, to something bordering on awe.

To these trained eyes, what I was doing was simply impossible. It was a level of skill that transcended technique and approached art.

Lisa had found a thick, original German-language repair manual from somewhere. She flipped through the pages frantically, her eyes darting between the book and my hands. Her mouth fell open.

“Oh my God… your procedure…” she stammered, her voice trembling. “It’s in the manual… the ‘Emergency Calibration for Extreme Conditions’… But… my professor in Germany said this was just a theoretical best-case scenario, that no one could actually do it in real life!”

The procedure demanded an impossible level of feel, experience, and judgment. One tiny mistake would scrap the entire core module.

I didn’t look up, my focus entirely on measuring the clearance of a ball screw with a specialized caliper.

“Theory?” I said quietly. “Twenty years ago, in Hannover, the old masters at DMG taught me this, step by step.”

I paused, wiping the sweat from my brow.

I looked up at Lisa’s stunned face and revealed a piece of my past.

“Twenty years ago, Hannover, Germany. DMG headquarters. I was in the first group of technicians they ever invited from my country.”

My mind flashed back to a time when I was full of fire and ambition.

FLASHBACK

In my twenties, wearing a crisp blue uniform, I stood before the most advanced machine tools in the world, my eyes shining with a hunger for knowledge. I was surrounded by stern German engineers and top technicians from across the globe.

Driven by a stubborn refusal to be second-best and a natural gift, I mastered every technique in record time. I was even debating design improvements with the German masters. We drank beer together, pulled all-nighters over blueprints. We gave names to every machine we calibrated. A blond, blue-eyed engineer named Klaus clapped me on the shoulder, saying in his broken English, “John! You are a genius! A true mechanical genius!”

END FLASHBACK

I looked at the dusty machine before me, my gaze softening.

“Back then, this model was called the DMC-60H. We called her ‘Ingrid’.”

“She was like a proud, precise German woman. You had to treat her with the utmost gentleness and understanding. Only then would she show you her perfect side.”

“I’m just… catching up with an old friend I haven’t seen in years.”

Lisa was speechless.

She stared at me—this middle-aged man in a stained tank top, his back slightly stooped. She couldn’t reconcile the man before her with the image of a washed-up factory worker laid off and forced to take a menial job. The cognitive dissonance was overwhelming.

“Who… who are you?” She used a respectful tone, her voice quivering.

I just smiled and didn't answer. I turned back to my work.

Using a special technique, like a dragonfly skipping across water, I began to tap the locking pins of the calibration module. The force and location of each tap were terrifyingly precise.

The only sound in the workshop was the crisp, rhythmic tink, tink, tink.

That sound was like a hammer, striking at the heart of every person watching. It shattered their deep-seated arrogance, the belief that a person’s worth was measured by their degree or job title.

Three hours later, the mechanical calibration was complete. I fitted the last casing panel and tightened the final screw. The entire process had been flawless. Of the hundreds of parts I had removed, not a single one was left over, not a single one was missing.

“Done,” I said, straightening up and letting out a long breath.

The workshop was deathly still. Everyone held their breath, waiting for the miracle.

Rick’s fists were clenched so tight his knuckles were white, his palms slick with sweat. His face was a cocktail of hope, anxiety, and disbelief.

Lisa looked at me with open adoration. She walked to the control panel, took a deep breath, and with a slightly trembling hand, pressed the green start button.

VMMMMMM—

A smooth, pleasant electrical hum filled the air. The machine’s LCD screen lit up, and a series of indicator lights flashed on as it began its self-diagnostic sequence.

“It’s on! The screen is on!” a worker shouted excitedly.

A massive grin of pure joy spread across Rick’s face.

It worked!

It actually worked!

This hunk of metal, condemned by eight experts, had just been brought back to life by this unassuming stockroom manager.

But their joy lasted less than ten seconds.

BEEP—BEEP—BEEP—

A shrill, piercing alarm cut through the workshop’s quiet hum.

The LCD screen flashed, displaying a wall of red error codes in German. At the very top, a bold warning message stabbed through everyone’s hopes.

SYSTEM OVERLOAD! SHUTDOWN IMMEDIATELY!

The alarm was so sharp it felt like it could puncture eardrums. The lights that had just turned on all went dark. The codes on the screen scrolled frantically before settling on a solid, bloody red.

The celebratory mood that had just filled the workshop was instantly doused in ice water.

Rick’s smile froze on his face, twisting into something uglier than a grimace. How could this happen? It was working. Why would it suddenly alarm out?

Just then, hurried footsteps echoed from the workshop entrance.

“Mr. Thorne! Mr. Thorne! I brought Professor Evans!”

It was Mark, the assistant, escorting a man in his late fifties wearing a sharp suit. It was the head of the “eight experts” Rick had hired, Professor Evans himself.

The moment the professor walked in and saw me, the “stockroom guy,” standing next to the machine, his face darkened.

“Sheer madness!” he boomed, his voice dripping with academic arrogance and the fury of a man whose authority had been challenged. “Mr. Thorne, didn't I tell you? This is an incredibly delicate piece of equipment! Any contact by an untrained person could have devastating consequences! How could you let a handyman touch my ‘patient’?!”

He rushed to the control panel and glanced at the blood-red error codes, his face contorting into an expression of profound grief. He slapped his thigh dramatically and pointed at the screen. “It’s over! It’s completely ruined!”

“Mr. Thorne, the motherboard is completely fried! Before, it was just a problem with the drive chip; there was a glimmer of hope. But after he’s been messing with it, a high-voltage surge has fried the main CPU! This machine is now, officially, a pile of scrap! There is zero hope of repair!”

Every word from the professor was a sledgehammer blow to Rick’s heart.

Rick’s face went from pale to ashen, and finally to a dark, thunderous black. He whipped his head around, his eyes locking onto me, a gaze so cold and raw it could have stripped flesh from bone.

“John… Carter…”

His voice was a guttural snarl, filled with the rage of a man who has been deceived and betrayed.

The “life or death” agreement I had signed, the half-million-dollar debt, felt like an invisible mountain crashing down on top of me.

The looks from the crowd—gleeful, pitying, scornful—weaved into a suffocating net, trapping me in the center.

I met Rick’s murderous glare and Professor Evans’s smug, triumphant sneer.

And I said, each word perfectly clear, “He’s wrong.”

“This isn’t an overload.”

“It’s a safety protocol. Someone intentionally altered the safety thresholds in the system.”

The professor burst out laughing before I had even finished. “Preposterous! Absolutely preposterous!” He pointed a finger at my nose and addressed the room. “Listen to this! A stockroom manager who can’t even read a circuit diagram is lecturing me on safety parameters? This is the most ridiculous thing I have ever heard!”

“This is a classic cascade failure caused by hardware damage! Do you even know what a safety parameter is? Do you have any idea what level of security clearance is required to access this machine’s backend?”

He turned to Rick, his voice dripping with feigned sympathy as he twisted the knife. “Mr. Thorne, you were too soft-hearted, and you let this con artist fool you! And now look! Five hundred thousand dollars, down the drain!”

Rick’s fists were clenched so hard they were cracking. Veins bulged on the back of his hands. He pointed at me, his voice trembling with fury.

“Carter, you better have a damn good explanation.”

“Or that contract…”

“You’re not walking out of this workshop today!”
