Volume 4 - Chapter 5 – A gearbox, a magic turbine, and… (1/2)

04-05　A gearbox, a magic turbine, and…

The next morning, after Jin woke up and had his breakfast, he began making a gear.

First, he created a linear gear as a reference.

First he prepared a straightened adamantium strip, then he made the teeth of the gear. He didn’t worry about the module (the size of the teeth). This is how Jin normally works. (TLFalin: It actually says module and has the part in the parentheses, it seems the author researched this to give a more authentic explanation, so there may be more as the chapter progresses)

「Is this much good?」

Because Jin plans to use it for a car, it needs to be strong, but since he’s using Adamantium, it’ll be work well at a small size. Although it’s simple to make it big by itself, Jin decided to start from something small.

For the time being, he made 200 copies of his first one. These were made without difficulty.

If lined up face to face, it becomes immediately apparent that the spacing of the teeth is the same and they’re all identical.

「Well, if I can make do with one band, and . Could I… yes, I can do it!」(TL: He’s muttering, so this was hard to translate)

He completed the teeth on the linear gear.

「After that, yeah… make a gear with the number of teeth that I need to fit this. Yes, it’s a success! Now, into a circle. I think I’m done with the outside of the gear with this.」

At this stage, he has a gear with his desired number of teeth. It is, so to speak, a doughnut with teeth.

「Now, to fill the inside circle of the gear, . Great, it worked!」

In front of Jin laid a completed spur gear.

When Jin made another gear with a different number of teeth and tried to engage the two, they engaged so neatly that Jin began to feel like dancing.

If a spur gear is made, Jin can make a bevel gear somehow as well. However, it will be limited to the same number of teeth.

Still, it was fascinating that it could change the rotation 90 degrees, and it would quickly increase the kinds of machines Jin could make.

「Yosh, let’s make a car!」

He made the chassis with light silver and got carried away and made a 4 cylinder engine, no, a 4 part engine. The tires are made neatly from rubber and in the afternoon the car is completed.

「Un, un, it’s nice.」

Because there’s no transmissions, it can only be operated by an accelerator and a brake, so it’s not automatic. Because the output of the golem is constant, it can work.

After driving around in the flat area in front of his research center, Jin got off satisfied.

「Father, I feel that the golem horses were more versatile.」

「Huh?」

Jin couldn’t understand Reiko’s question for a minute, but shortly after realized the implications of it.

The airplane had a and the ship had a

Although Jin had thought of the golem engine for land that’s paved, he forgot that most of the world hasn’t been paved.

How much time until it’s a cars turn in this world?

「Hmm, did I become complacent? Well, it’ll work for this island.」

Was said,

「Reiko, have Topaz make a road network on the island. You don’t have to pave the surface, use , It’ll prevent the weeds and also allow something heavy to go across it.」

「Yes. Should I give priority to Tatsumi Bay, the fields, and the airport?」(TL: Was it called Tatsumi Bay in a previous translation? I’ll have to come back to this.)

「Ah, yes, please.」

Because I made the airport for the airplane, the maintenance of the road was urgent business. A large Warp Gate is installed at each place as well, but a road is still necessary.

「Aaah, I’m hungry.」

It was already pitch black out.

「Father, I made dinner today.」

「Ah, Reiko, I’m looking forward to it.」

Because Soleil and Luna were busy mass-producing the airplanes and ships, Reiko took charge of cooking for Jin.

「It’s pure white bread, isn’t it?」

「Yes.」

Reiko peels the wheat, one by one, and the bread was made with the ground down flour.

「Mmm, tasty.」

Jin eats the bread and has vegetable and fish soup, after all, the bread without the crust is is more delicious when mixed in.

「I’m sorry, the rice hasn’t been found yet.」

「No, I understand, I’m asking for a lot. I’ll search for it in the western country I’m going to this time.」

Since they couldn’t find rice in the port town, Port Rock, Jin thought they might find it in a western country where the things might be different and unusual.

7 days since he returned to Hourai Island…

「Might as well make a turbine.」

The first day Jin began with the lines. The principle was simple, to put an impeller in a sealed container and turn it with wind magic.
