Magi Craft Meister

"Hmmm......"

Jen was thinking about a consultation from Marcia and Rodrigo.

There are several ways to increase RPM and torque.

Firstly, if the material is made Penglai compliant, it can be improved to more than ten times what it has been.

But that's not common.

"And then"

In a way that turns the actual 'reciprocal engine', or reciprocating motion of the piston, into a rotating motion, the parameters bore and stroke come into effect.

The bore is the diameter of the piston and the stroke is the reciprocating range of the piston.

The bore-to-stroke ratio is called the bore-stroke ratio, which serves as one of the guidelines for engine characteristics, but Jen doesn't know that far.

However, I understood that if the stroke was reduced, the reverse torque that could be higher would be smaller, and if the stroke was increased, the rpm would drop but the torque could be increased.

And to increase torque, you also need to increase the number of cylinders.

That's typical of a V8 engine or a V12 engine.

"Star-shaped engine......"

It is the type that is often used for aircraft.

"But I guess this is a series or a V"

Jen still remembers making a golem engine for automobiles.

"But it's too long in series..."

"Uh, gin?

"Horizontally opposed strikes off vibrations, I hear, sure."

"... hey"

"Eight cylinders horizontally opposed... not, if it's an eight-series"

"Hello."

"... Mr. Marcia, if Brother Jin had that face, he'd be smarter to leave it alone for a while"

Elsa seems to have figured out quite a bit about Jen.

"Okay, it's settled.... Marcia, I think you can."

Jen turns to Marcia like nothing happened and states pale.

"Oh, yeah. Good."

"Well, let's just make it"

But I waited there, but it takes a while.

"Brother Jin, it's time for lunch"

The time is just around 11: 00.

"Father, don't skip lunch."

The time difference between Penglai Island and Potlock is about two hours and forty minutes.

Considering the jet lag, it was Jens who had breakfast at 9 o'clock in Penglai, but at 11 o'clock in Potlock it was 13: 40 in Penglai. I'm pretty hungry.

Marcia and Rodrigo also know about jet lag, so

"Right, Jin. Let's have lunch."

So I left the workshop and headed toward the store to do the work.

Since Jen has built more, there are kitchens that can easily be built for about ten people, and we can prepare the store's Bacchus and Jeremy's minutes at the same time.

"It's lunch, so it's gonna be easy."

Fifteen minutes later, with that said, Marcia served the classic: bread, soup, salad and fruit juice.

"This salad is delicious"

It seems to fit Jen's mouth whether vegetables specific to potlock are used.

"Really?

"Isn't this the scent of Kryptona?

When Elsa, who likewise ate the salad, said so, Jen nodded much as she noticed.

"Oh, yeah. This is beetle flavor!

Kryptona is a 'mitzvah' known to Jen. In the village of Kaina, it is a normally grown wild grass, which is eaten every once in a while.

"Sure, it would be delicious to put in a salad"

They were Jens who had floated on suckers but never put them in the salad.

"Next time, we'll even let you in"

"Mmm."

It was Jen and Elsa who said such things.

Well, it's a little late for Jen and Elsa, and after a little early lunch for Marcia and the others, it's finally engine building.

"I'd rather make the ingredients out of iron than bronze."

I wanted to use a more robust material because the power should increase.

"Oh, I'm buying it right. I use it for strength."

There was an increasing demand for such materials because improved and enhanced arrows could use more engineering magic than coarse magicians (Magicraftsmen).

"Uh, iron... Hmm, carbon steel... 0.4 percent carbon? As it happens, does it also contain some manganese? Enough."

To this, nickel and chromium shall be added as alloy steel, referred to as SNC material.

It is an alloy steel commonly used in structural materials, etc.

That's Jen's private arena, but after that, Elsa and Arrow will also be asked to help.

Especially since Arrow will be entrusted with future maintenance.

"Let's use artillery for the bearings.... Arrow, don't forget the maintenance here"

"Yes, I understand"

In the case of reduced polishing, the rattling occurs and the efficiency is reduced, so the priority is high as a maintenance target.

And Jen made a crankshaft and a golem arm part, sharing an enclosure for Elsa and a muscle part for Reiko.

Complete in about half an hour. This is the only story that if Jen is alone, it probably won't take ten minutes.

"All right, prototype's done. Let's move it."

The prototype engine is about 50 cm long, 25 cm tall and 50 cm wide. It weighed less than thirty kilos.

Keep the energy source in a magic reservoir (mana tank). Because the potlock has a low latitude, the free magic hormone (ether) concentration is also slightly lower, and other than Jen, efficient operation is difficult.

"Start"

The engine started turning.

Horizontally opposed, so less vibration, quiet.

"Yeah, you've shortened the stroke, so it's spinning."

The marked axis is about 1,000 to 1300 revolutions per minute when Reiko counts.

There seems to be a bad torque, too, which can be described as a success first.

"Jin, I think I can use this. Thanks!"

"Lord Jin, if you will, I would like you to give me another contract."

It will be added to one of the engines wholesale from Penglai to Marcia Workshop.

Since it is not possible to do so free of charge, the cost of materials and technical fees were taken into account, and the contract for five units of the same size as the prototype was set at 20,000 tons (about 200,000 yen) per month for a total of 100,000 tons.

On the Penglai side, Craftsman (Smith) Golem will be in charge of production under the leadership of Lao Jun.

"Bye Jin, thank you"

"No, this way, it was helpful."

At 3 p.m. Potlock time, Jen, Elsa and Reiko returned to Penglai.

"That's a lot of help..."

'Yes, my lord (My Lord). I have spoken to you. The communication device, the observation room, has been woven into the plan. "

Soon old man will report to me. [M]

You will ask your husband (My Road) for the relay base.

"Right, okay. As far as I'm concerned, I'll think about the relay base and... the entertainment room."

Such interior problems will be easy to add later, but it is desirable to deal with the design as quickly as possible.

"Brother Jin, I will consider the meal menu with my mother."

"Oh right. Please."

"Mmm."

I want to make a menu like eating on the ground one meal a day, so I need to think about how to select ingredients, store them, and even cook them.

We decided to leave that to Elsa and Jen to think about new equipment, including a relay for communications.
