Magicraft Meister Part 1

The next morning, Jin finished his meal early and immediately started to build a car for popularization.

The most important part to be modified was the reduction gear.

There is no need for a transmission like that of a modern earth car, and Jin does not know the structure. Therefore, the reduction gear has only one stage.

In other words, the output of the smaller and lower-powered Golem engine is to be decelerated by gears to increase torque.

The reduction ratio is 1:5.

The torque of the engine can be reduced to one-fifth. In other words, the size of the engine can be reduced.

The calculation to reduce the horsepower by a factor of 5 becomes complicated, and Jin is not confident that he will get the correct answer.

Therefore, he decided to make an engine with one-fifth the size for the time being, but then he reconsidered that 10 centimeters was indeed too small.

"Let's make it 20 centimeters."

If we consider only the force of the magical muscle, the answer is almost correct. The force is proportional to the cross-sectional area of the muscle.

With the help of Erza and Reiko, a 20cm class double golem engine was completed.

They installed it in a car with gears to decelerate the engine.

"Modification is also a hassle, so let's make a new one," said Jin.

Jin's quintessence was in full swing. However, the car that was completed yesterday will not be stored in vain because he thinks that it should be used exclusively for the Horai Island or the Kunlun Island.

Since it was made yesterday, the prototype car for popularization was completed in a short period of time.

"Well, how about the power?"

When we test-drove the car in the plaza in front of the research institute, we could clearly feel that the car lacked power at the time of start-up acceleration.

"I guess 1:5 isn't the right gear ratio. ......"

Since 1:10 would be too large, I changed the gear ratio to 1:7. In fact, the number of teeth of the gear attached to the pinion gear ...... Golem engine side was reduced.

At this time, if the number of teeth of the meshing gears is made to be prime (the greatest common divisor is 1), the teeth of the gears will mesh evenly and decrease evenly, so it is easy to maintain the condition.

Jin set the golem engine side to 13 and the axle side to 90.

"Oh, that's good.

This seems to have solved the problem of lack of power during acceleration.

"The top speed is ......, well, that's about right."

Even with the gas pedal fully depressed, the speed is still about 20 km/h. That's about the speed of a human runner. That's about the speed of a human sprint.

"Well, it's not dangerous, and it's an unusual toy.

It is fast enough for city traffic. Jin decided to build a car based on this configuration.

The power and suspension will be the same as the No. 2 car.

The seats are upholstered in leather and filled with to make them comfortable.

The problem is the body.

<.

Elsa helped me with the design. The basic structure is made of bronze and wood, with some parts gilded to give it a luxurious look.

After all, this is a car that the emperor will ride in.

Since it is intended to be exclusively for her majesty, the emblem of the imperial family << three crossed swords (Dreischwerdt)>> is placed on the side of the car.

"Yes, it's good."

The horseless carriage is literally finished.

Now all we need is a driver golem.

This is also made of bronze and made by a young man type. It also has a servant-like function, such as opening the door when getting in and out of the car.

This type of golem is called a "driver (furrer). This is what we call a driver in the Shoro Kingdom. This is the first one, so it is Furrer 1.

Various equipment is installed, and it is now complete.

To see if there are any omissions in the equipment, Jin compares it with a modern Japanese car that he remembers.

Jin does not have a driver's license, so he does not know much about cars as an enthusiast, but he knew some things about cars because he drives cabs and cars driven by his colleagues for company business.

I had forgotten about the equipment, saying, "Oh, it would be nice to have windshield wipers.

This method was quite effective, as I could remember some equipment that I had forgotten.

After spending the whole morning making some additions, we had a <> luxury car.

"......This is not going to be popular."

"...... yeah."

Erza, who was helping him, fully agreed with Jin's words.

As a result of the elaboration of the vehicle for the exclusive use of the Empress, it had become something that most of the nobles, let alone the common people, could not afford.

For example, the headlights. Instead of using magic lamps in the style of a cantera, they use the magic of <> to give a forward directional effect.

Then there are the windows. The larger windows are all made of quartz glass and are highly transparent. To prevent danger, they are made of <>. It cannot be broken even by a thrown stone.

At the same time, the driver's seat is slightly lowered so that it does not obstruct passengers' view of the outside. The design was inspired by large sightseeing buses.

The horn. It is not a shrill, high-pitched sound, but a sound like a bicycle bell. For this, we used a recording/playback device developed by Elsa.

It also has a built-in micro refrigerator, which can be used to drink cold drinks in summer. In winter, it can be switched to a warming cabinet.

Four spare tires are stored under the floor.

As for the vehicle's performance, it has settled on a maximum speed of 20 kilometers per hour, and is limited to city or suburban use.

Except for the driver, Golem, the vehicle has a capacity for six persons. The configuration is front row for 3 persons and rear row for 3 persons.

The seats can be rotated and reclined so that they can face each other, face the direction of travel, or lie flat for a nap.

The mana tanks are large enough to last for two consecutive days of operation.

"We should also build a mana supply machine with improved efficiency ......<>."

This is because it will be necessary if we increase the number of magic tools to improve our lives in the future.

Then Elsa said she wanted to make one.

She said, "Jin, let me try it.

Jin nodded his head, as it was not particularly difficult.

"Okay, try it. Just don't make it too small, and make it as big as possible.

The mana supply machine currently in use is about the size of an office desk.

Jin advised to make it only about two times smaller than that.

"Okay."

Jin thought in his mind that it would be like a PC software program that does not make the box smaller.

Jin watched Erza's work, wondering if it was human psychology that if you make something too small, you lose appreciation for it and treat it poorly.

"Erza has improved, hasn't she?

Such a compliment came out of his mouth.

"Oh, thank you."

Erza is stunned by the sudden words. A magi crystal fell from her hand.

"Oops!

"That was close, wasn't it?"

Reiko caught it before it hit the floor. Jin pulled his outstretched hand back absentmindedly.

"Thank you, Reiko."

"No problem."

Erza went back to work, and the mana server was completed in about 30 minutes.

"Yes, it's good work. Good job, Elsa."

"Yes, thank you."

"......?　Wait, ......"

As Jin looked at the completed mana server, he had an idea.

"Brother Jin, what's wrong?　Did something go wrong?

Erza's voice sounded a little worried. But Jin patted her on the shoulder,

"You just need to install this!

He said pleasantly.

"Then we can keep running without refueling."

In short, this is a gigantic <.

"Oh, that's what I mean."

Erza seemed to understand and smiled.

So, we install a mana server. This allows the car to run semi-permanently.

Then Lol comes to tell us that lunch is ready.

"Master, lunch is ready."

"Oh, I see."

Jin and Erza washed their hands and went to the dining room.

Reiko followed Jin rather than ...... them, and Edgar was a step behind them in the dining room after cleaning up the mess in the workshop.

"Oh, udon today.

Today's lunch was tempura udon.

"Yes, I made it myself after learning from Perid and the others.

"Yes.

The tempura of prawns and vegetables (pumpkin or something similar) was fried to a crisp, and the sauce was just the right thickness.

The udon noodles seem a little weak, but I am not sure if this is due to the selection of flour (the blend of strong, medium and light flours) or the way it is made.

Jin likes noodles with a strong and sturdy texture, but Elsa seemed to prefer udon with about the same texture as this one, and she even ordered another bowl of udon, saying it was delicious and tasty.

"Well, then, let's make our own car.

"Hmmm..."

After lunch, Hitoshi and Elsa started to build a car for the public once again.

The appearance of the engine and undercarriage were identical, but the materials could be changed to make it more powerful.

The Golem engine is made of Orihalcon instead of bronze, and the magical muscles for powering the car are the standard ones of Horai Island, so it is expected to be about 5 times more powerful.

By omitting decorations, the weight can be reduced slightly.

However, only the djinn's emblem, <>, should be painted on both sides and on the roof in large letters.

The driver decides to educate Edgar.

"The question is, how do we get this to Leuthart?

The weight of each car was about 500 kg, which seemed a little heavy to load on the <>.

Then the old man came up with an idea.

<

"Oh, I see. From there it would be easier to transport them to Miyagi.

Jin decided to adopt this idea.
