I am a primitive

As long as you know the principle, then the rest will be easy to do.

Based on this principle, improvements can be made on the basis of the water wheel, making this thing more suitable for the water wheel!

After more than half a day like this, Han Cheng preliminarily fixed these things.

Sitting here, drinking two sips of mint water, and stretching beautifully, Han Cheng walked out of his living room with the things written and drawn in his hands, and went to find Mao Er.

Mao Er, the little carpenter inspired by Han Cheng's ink fountain, has become very mature now.

Among the craftsmen in Jinguan City, his craft is the best and the most brilliant.

It is precisely because of this that Han Cheng asked him to be the leader of the carpenter team in Jinguan City, leading the carpenters in the tribe to do various things.

When Han Cheng came over, Mao Er was busy here.

He held the 'ears' on both sides of the plane with both hands, bent his back slightly forward, and was working hard to smooth the wooden board placed on a tall, simple four-legged stool.

Every time I push it forward, some shavings will appear in a roll, and then gushes out from the hole of the plane and falls to the ground.

Through his movements, this side of the wood quickly became smooth and smooth.

What he is doing now is the front beam of the frame of the ox cart.

The Bullock Cart Maoer has already built three cars, and the fourth one is being built now.

There are more cattle in the tribe, and the carts have to keep up.

The strength of the ox is great, so the ox cart is also big, and it can pull a lot of things at one time. Whether it is used to transport food or pull soil, it is very good. Naturally, it needs to be made more.

In addition to Mao Er, there are nearly twenty people busy here.

Some of these people are pulling big saws in groups of two to untie the boards, and some are chiseling holes with hammers and chisels in their hands.

Unlike Mao Er who is making frames, most of the work these people do is doors, windows, tables and chairs.

For the tile-roofed houses that are being built.

In addition to making doors and windows, several people are weaving gratings there with some soft branches.

This is the house built, after the beams and rafters are installed, and then laid on top.

"Son of God."

"Son of God."

……

When Han Cheng arrived, everyone who was busy here greeted Han Cheng with smiles.

Seeing this, Han Cheng nodded to them with a smile.

"Look at this thing."

Han Cheng walked all the way to Mao'er's side, reached out and handed the paper in his hand to Mao'er, and said to Mao'er with a smile.

When Mao Er saw the paper in Han Cheng's hand, he felt excited and looked forward to it.

At this time, after hearing Han Cheng's words and confirming the conjecture in his heart, he became even more excited!

As the direct disciple of the No. [-] carpenter in the tribe, Mao Er naturally knew what the Son of God had brought, and he also understood what this thing and the behavior of the Son of God meant to him!

This means that his technique has been approved by the Son of God!

It is a great affirmation of oneself!

After all, this kind of thing for making new utensils was a lame patent in the past!

At this time, the son of God was handed over to himself. Although part of the reason was that he stayed in the main tribe and did not come, it was also a great affirmation of himself!

At that moment, the cat's ears in agitated mood wiped their hands vigorously on their body, then quickly stretched out their hands, took it over, and watched it carefully...

"The water pestle in the tribe is too slow to pound rice, so I'm going to make a new kind of water pestle.

This kind of water pestle has a complicated structure, but it is very easy to use.

A shaft can drive at least two hammer heads up and down to pound rice.

Moreover, the frequency of the hammer head swinging up and down is also high..."

After Mao Er looked at it for a while, Han Cheng said to Mao Er aloud, explaining to him what it is, what its use is, what effect it will have after it is made, and how significant it is to the tribe.

Knowing these things will help Mao Er to be confident.

It is more vigorous to do it, and it is easier to find ideas.

After telling the story, Han Cheng told Mao Er how the water hammer works under the action of the water flow, and how some parts are generally connected.

Many of these things cannot be clearly explained on the pictures, or it is very troublesome to record and describe them. It will be clearer and more convenient for Han Cheng to tell them face to face, and it will be more conducive to the cat's ears to understand...

"When~ when~ when~"

In the carpenter's house in Jinguan City, there was a clanging sound.

The best carpenter, Mao Er, staying here in Jinguan City, is punching a hole at one end of a very smooth wooden stick with one hand and a chisel.

The wooden stick is extremely solid, even though the cat's ear is using one of the few chisels made of meteoric iron in the tribe, once the chisel is lowered, not many sawdust can be chiseled from it.

It is necessary that the stick be solid, since it is the circumscribed part of the shaft which exists like a waterwheel.

The production technology of Qingque tribe's axles has matured a lot.

Also because of this, the shaft of the waterwheel, the cat ears and they didn't do anything difficult.

It's just that an axle that should have been used on the ox cart wheel is used here, and that's it.

However, the axle of the bullock cart is still a bit short for this.

So the cat ears thought about connecting a section to one end of the axle.

The connected shaft is not used for load-bearing, but is used to rotate with the rotation of the water wheel, thereby driving the movement of the water pestle installed below.

Therefore, it is enough to only use wood, and it will not be worn out.

After doing this for a while, the long holes in the wood were chiselled.
