Chapter 94: The Drive Unit

The second major component of Prototype 01 entered production at 6:03 the following morning.

Adrian was there again.

This time, however, nobody called it the first piece.

The chassis frame had already survived its initial inspection overnight. It sat on a reinforced assembly stand at the far end of the workshop, waiting for the next components to arrive.

The machine preparing the drive-unit housing was considerably smaller than the one used for the chassis.

It was also considerably more precise.

Miriam stood beside the operator as the first block of alloy was secured.

Adrian walked over.

"Any problems?"

"Not yet."

"That’s encouraging."

Miriam looked at him.

"Don’t say that."

"Why?"

"Machines hear confidence."

Adrian laughed.

"I thought you were an engineer."

"I am. That’s why I don’t trust anything until it has survived testing."

She turned back toward the machine.

The cutting process began.

Unlike the chassis rail, the drive-unit housing required tighter tolerances. The electromagnetic drive system depended on precise alignment between several components, and even a small deviation could affect efficiency, vibration or thermal performance.

Adrian watched the tool move.

"How sensitive?"

Miriam knew what he meant.

"Depends on the section."

"Give me a number."

"Some areas are measured in tenths of a millimetre. Others are much tighter."

"Could we loosen any of them?"

"Not without redesigning the assembly."

Adrian nodded.

"Then we don’t."

The machine continued.

For almost forty minutes, nothing happened.

That was a good thing.

Then Miriam’s tablet vibrated.

She glanced at it.

Her expression changed.

"What?"

"Temperature."

Adrian looked toward her.

"Cooling?"

"No. Cutting zone."

"Too high?"

"Four degrees above our expected maximum."

The operator stopped the machine.

Miriam moved closer to the display.

"Tool temperature is rising."

Daniel appeared behind them.

"Again?"

Miriam shook her head.

"Different problem."

Adrian looked at the half-machined housing.

"What’s causing it?"

"Material behaviour."

She studied the data.

"The alloy is harder in this batch than the sample we used during programming."

Daniel frowned.

"Same specification."

"Same specification doesn’t mean identical behaviour."

Adrian looked at the machine.

"Can we finish the part?"

"Probably."

He smiled.

"There it is again."

Miriam gave him an annoyed look.

"I’m beginning to dislike you."

"Only beginning?"

She almost smiled.

Then she turned serious.

"If we continue at this cutting speed, we might damage the tool."

"Then don’t."

"That increases machining time."

"How much?"

"Maybe eighteen minutes."

Adrian looked at the clock.

"Then we spend eighteen minutes."

Miriam nodded.

The cutting speed was reduced.

The machine continued.

An hour later, the housing emerged.

The operator removed it carefully.

The inspection team began checking the dimensions.

One measurement.

Then another.

Then another.

Miriam watched the numbers.

"Within tolerance."

Daniel exhaled.

Adrian nodded.

"Good."

Miriam wasn’t smiling.

"What?"

She pointed at the cutting tool.

"Look."

The tool had developed a visible wear mark.

Adrian frowned.

"How much did it cost?"

"The tool?"

"Yes."

"About £4,000."

"And how many housings can it make?"

Miriam hesitated.

"With the current material?"

"Yes."

"Maybe eleven."

Adrian looked at the finished housing.

"If we’re making ten thousand vehicles?"

"We’d need nearly a thousand tools."

Adrian nodded slowly.

"And that’s before production scaling."

"Exactly."

He looked at Daniel.

"Find out what the tool supplier can offer us."

"Volume discount?"

"Not just that."

Adrian looked back at Miriam.

"We need a better process."

The manufacturing team spent the next four hours trying to solve a problem that hadn’t existed in the design studio.

The electromagnetic drive system worked.

That wasn’t the issue.

The issue was making it repeatedly.

Miriam brought together the manufacturing engineers, materials specialists and Northbridge technicians.

The conversation quickly moved away from the prototype itself.

"What if we change the tool geometry?"

"It’ll help the wear, but the surface finish gets worse."

"Change the coolant?"

"Better thermal control, but we’re adding complexity."

"Reduce cutting speed?"

"Too slow for production."

"Different alloy?"

"Then the structural calculations change."

"Coating?"

"Possible."

Adrian listened from the side of the room.

Nobody was looking for a miracle.

They were looking for one percent here and three percent there.

That was what manufacturing looked like.

Not one giant breakthrough.

Thousands of small improvements.

Eventually, Miriam placed both hands on the table.

"Stop."

The room went quiet.

"We’re trying to solve the tool problem by protecting the tool."

She looked around.

"What if we stop making the tool do so much work?"

Daniel frowned.

"Meaning?"

"We’re removing too much material."

She pulled up the housing design.

"The current blank is thirty-one percent heavier than the finished part."

Robert looked at her.

"Because of the machining?"

"Yes."

Miriam rotated the model.

"We’re essentially buying material just to throw it away."

Adrian leaned forward.

"Change the blank."

"How?"

"Near-net shape."

Miriam nodded.

"Exactly."

She began outlining the idea.

Instead of starting with a large solid block, they could use a forged or precision-cast preform closer to the final shape.

Less material removed.

Less cutting.

Less heat.

Less tool wear.

Shorter machining time.

Higher consistency.

But there was a problem.

"That requires another supplier," Daniel said.

"Or another capability," Adrian replied.

Miriam looked at him.

"You’re thinking of bringing it in-house."

"I’m thinking of finding out what it costs."

Robert sighed.

"That’s how this keeps happening."

Adrian smiled.

"How what keeps happening?"

"We solve one problem and accidentally create another company."

The room laughed.

Adrian didn’t disagree.

By afternoon, Daniel had found three potential suppliers.

One was in Germany.

One was in northern England.

The third was a small specialist forging company in Wales.

The Welsh company was the most interesting.

It had forty-seven employees and a facility that had been operating for thirty-six years.

Its equipment was old.

Its order book was full.

Its owner, Gareth Morgan, had already refused two acquisition offers.

The first had come from a European industrial group.

The second had come from Meridian.

Daniel placed the information in front of Adrian.

"Why did he refuse?"

"Didn’t want to sell."

"That’s simple."

"Not entirely."

Daniel continued.

"His father founded the company. Gareth took over fifteen years ago. He’s profitable, but he’s been investing heavily in upgrading the forging equipment."

"Why?"

"Because he thinks precision manufacturing will come back to Britain."

Adrian looked at the report again.

"What does he need?"

"Money."

"How much?"

"About £22 million for the expansion."

Adrian looked up.

"And Meridian?"

"They offered to buy seventy percent."

"How much?"

"£58 million."

Adrian closed the report.

"Call him."

The conversation with Gareth Morgan lasted forty minutes.

He was a broad-shouldered man in his early sixties with grey hair and the cautious manner of someone who had spent his life negotiating with people who wanted something from him.

Adrian explained what Sterling needed.

Gareth listened.

Then he asked the question Adrian expected.

"Are you trying to buy me?"

"No."

"Why?"

"Because I don’t need to own your company."

Gareth leaned back.

"Meridian said something similar."

Adrian smiled slightly.

"They didn’t."

Gareth laughed.

"No. They offered to leave me with thirty percent."

"What do you want?"

"Control."

"Then keep it."

Gareth studied him.

"What’s the catch?"

"A long-term supply agreement."

"How long?"

"Ten years."

"Minimum volume?"

"Yes."

"Expansion financing?"

"Yes."

"How much?"

"Up to £25 million."

Gareth’s expression changed.

"You’ve already done your homework."

"We’re trying to build a vehicle."

"You’re building more than a vehicle."

Adrian said nothing.

Gareth continued.

"Your company has bought manufacturing companies. Materials companies. Energy technology. Now you’re financing suppliers."

"We’re building a manufacturing network."

"Why?"

"Because I don’t want to discover five years from now that one supplier controls something we can’t replace."

Gareth nodded slowly.

"That’s a sensible answer."

Adrian leaned forward.

"I don’t want your company."

"Then what do you want?"

"Your capability."

Gareth smiled.

"That’s the first honest answer you’ve given me."

"It was the first question you asked that required it."

Gareth laughed.

By the end of the call, they had agreed to meet in Wales.

No deal was signed.

Adrian preferred it that way.

He had learned that the best partnerships weren’t created by forcing a signature onto a page.

They were built by finding out whether both sides wanted the same future.

At Sterling Industrial Works, the prototype continued moving forward.

The chassis frame was placed onto its assembly jig.

The battery enclosure arrived later that evening.

It wasn’t connected yet.

It didn’t need to be.

The team was checking fit.

James Fletcher stood underneath the chassis with a measurement device.

"Two millimetres."

Adrian crouched beside him.

"Problem?"

"Not yet."

James pointed toward the mounting structure.

"We have two millimetres more clearance than the original design."

"Is that good?"

"Depends what we do with it."

Adrian looked at him.

James smiled.

"We could use it."

"For what?"

"Thermal protection."

He explained the idea.

The additional space could allow a slightly thicker insulation layer around part of the battery enclosure without changing the external dimensions.

Adrian nodded.

"Do it."

James looked surprised.

"That’s it?"

"Is there a reason not to?"

"No."

"Then do it."

That was becoming Adrian’s favourite kind of decision.

Small.

Practical.

Permanent.

At seven in the evening, Emily called from Cambridge.

"Battery update."

Adrian answered.

"Go."

"We passed two hundred and fifty cycles."

"And?"

"Fourteen percent improvement is holding."

Adrian smiled.

"Good."

"But there’s something else."

His smile faded.

"What?" ℴ

"The thermal profile changed after prolonged cycling."

"How?"

"The cells are still within safety limits, but the heat distribution isn’t as even as the early tests suggested."

"Meaning?"

"We need to redesign the cooling interface."

Adrian closed his eyes briefly.

"How long?"

"Two weeks."

"Do it."

Emily was quiet.

"You aren’t going to ask me to rush?"

"No."

"Why?"

"Because I want the battery to work."

She laughed softly.

"Fair enough."

Adrian looked toward the workshop.

"We have enough problems already."

"That’s comforting."

He smiled.

"Good night, Emily."

"Good night, Adrian."

The call ended.

He stood for a moment.

Two weeks.

It wasn’t a disaster.

It wasn’t even unusual.

But every delay mattered when the target was eighteen months.

Adrian opened the programme schedule.

The battery work was not currently on the critical path.

James had deliberately built some flexibility into the early architecture.

That meant the delay could be absorbed.

For now.

Adrian closed the schedule.

The goal wasn’t to make every problem disappear.

It was to make sure no single problem could stop the entire programme.

That was what resilience meant.

Later that night, Adrian found himself walking through the factory alone.

The building was quieter now.

Machines still ran in several sections, but the frantic energy of the daytime had disappeared.

He stopped beside Prototype 01.

The chassis sat under bright work lights.

The battery enclosure rested nearby.

The first drive-unit housing had been placed on a protected table.

Three pieces.

That was all.

Three pieces that had taken months of engineering and millions of pounds to reach.

Adrian looked at them.

Then his phone vibrated.

Sophia.

Dinner tomorrow. Seven-thirty.

He smiled.

No business talk?

The reply came quickly.

Especially no business talk.

He typed:

Understood.

Three dots appeared.

And don’t cancel because a machine decided to misbehave.

Adrian laughed.

I won’t.

He put the phone away.

For a few seconds, the factory was completely silent around him.

Then a machine started in the distance.

Adrian looked toward the sound.

The work continued.

At 11:59 p.m., the System appeared.

[Daily Check-In Available.]

Adrian tapped it.

[Day 94 Check-In Complete.]

[Reward: £35,000,000 Liquid Capital.]

The transfer was immediate.

Adrian didn’t celebrate.

He simply looked at the balance before closing the notification.

The money was useful.

But the thing occupying his mind wasn’t the reward.

It was the factory.

Three physical components now existed.

A battery team had discovered a thermal problem before it became a failure.

A supplier relationship was being built in Wales.

A manufacturing process was already being redesigned before production had even begun.

And somewhere on a whiteboard inside Sterling Industrial Works, someone had written:

PROTOTYPE 01 — 18 MONTH TARGET

Adrian looked at the words for a long moment.

Eighteen months had sounded ambitious when he first wrote it.

Now it sounded like a deadline.

He turned off the workshop lights.

Tomorrow, another piece would be made.

Then another.

And eventually, if they kept solving the problems instead of pretending they didn’t exist, those pieces would become something the world could see.

Something that could move.

Something that could compete.

Something that belonged entirely to Sterling.
