“Ding~Ding~Ding~”

A series of clinking sounds were heard in the carpenter's house in Jinguan City.

Mao'er, the most skilled carpenter in Jinguan City, is drilling a hole at one end of a wooden stick that has been scraped very smoothly with an axe in one hand and a chisel in the other.

The wooden stick was extremely solid. Even though Mao Er was using one of the few chisels in the tribe that was made of meteorite iron, he was still unable to produce much wood chips with each strike.

It is necessary that the stick be strong, for it is the external part of the axle, as in a waterwheel.

The axle manufacturing technology of the Qingque tribe has become much more mature by now.

That is why it was not difficult for Mao'er and the others to make the axle of the waterwheel.

Just use an axle that was supposed to be used on an ox cart wheel for this, that's all.

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

So Mao'er thought of connecting a piece to one end of the axle.

The connected shaft is not used to bear weight, but is only used to rotate with the rotation of the water wheel, thereby driving the water mill installed below to move.

Therefore, it is enough to just use wood, and it will not be damaged.

After a while, the long holes in the wood were chiseled.

In this way, three holes were drilled in total, and the distance between two adjacent holes was 45 centimeters.

Moreover, these three holes are not on the same line, but are scattered in three different directions of the wooden pillar.

After drilling the three holes, Mao Er reached out and took the small rectangular wooden board that had been cut on the side.

One end of the wooden board is smaller, similar in size to the hole that was chiseled.

Put the small end of the wooden board against the hole, Mao Er picked up the axe and hit the board for a while, and the board was firmly fixed on the wooden axis.

The wooden board that hit the wooden axis still had twenty-three centimeters left on the outside.

Mao Er picked up a similar wooden pillar and nailed it firmly into the wooden axis using the same method.

After a moment, square wooden pillars of the same length, width, and thickness were firmly nailed into the three holes.

Because the three are not in a straight line, it looks a bit like the mace held in the hand of the leader of the Red Tiger Tribe.

After finishing this, Mao Er took it in his hand and checked it carefully. When he found that there was nothing wrong with it, he put it down and went to work on other things.

The function of this thing is to move the installed water-mill hammer head.

A short wooden pole moves one.

In other words, if this water mill is well made, it can drive three water mill heads at one time!

Using such a tool to pound rice would naturally be quite fast...

"Bang, bang, bang..."

Cat Ear, holding a meteorite axe in his hand, continued to swing it.

In front of him was a thick wooden wheel that was no less than thirty centimeters in diameter and forty centimeters long.

Eight lines are evenly divided around this thick wooden wheel.

Now, each of these eight lines has three holes that are one and a half centimeters wide, five centimeters long, and about six centimeters deep.

What Cat Ears was holding in his hand was a trapezoidal wooden board that was long at the top and narrow at the bottom.

On the narrow side of the board, there are three protrusions that correspond to the holes chiseled in the wood.

After Mao Er aligned it, he picked up a wooden hammer and hit the end of the board, slowly nailing it in and securing it.

The reason why a wooden hammer was used at this time instead of a bronze hammer or a harder meteorite axe was because the wooden board was relatively thin and there was a fear that it would be broken.

With continuous 'bang bang' sounds, the eight specially made wooden boards were gradually hammered in and finally nailed in.

After nailing these eight wooden boards, the appearance of this thing changed, and the overall diameter reached one and a half meters!

This thing is the water wheel used to drive the water mill.

After making the water wheel, Mao Er, with the help of some people, fixed the water wheel on one end of the bronze shaft.

After fixing it, lift it onto the finished shelf, find a good position, and fix it again.

After finishing these, Mao Er grabbed a blade of the water wheel with his hand and pushed it down with force (fa, second tone), and the water wheel began to turn in the air with a gurgling sound.

The other end of the bronze shaft, along with the solid wooden stick connected to it, also began to rotate together.

The rotation effect is pretty good.

After turning it several times, Maoer got some oil and dripped it on the connection between the shaft and the shelf below.

Then it started to continue rotating.

With the help of oil for lubrication, the water wheel turned much more smoothly.

Seeing this, Mao Er couldn't help but nodded with satisfaction.

Then he stopped people from turning the water wheel and instead took people to install the hammer head of the water mill that had been made here.

The hammer head of the water mill being installed is similar to the primitive water mill currently used in the tribe.

They are all shaped like an unbalanced balance beam.

At one end is a heavy hammer head, and the axis of the wood is horizontal, relatively close to the hammer head, about one-third of the way along the entire pole.

At the other end is an empty wooden pole with nothing on it.

Unlike the primitive water mill currently in use in the tribe, the lighter and longer section of the wooden pole was not taken out of the gutter. On the contrary, it was scraped to be extremely flat and smooth.

Moreover, the upper part of its high-raised tail is not flat, but is deliberately designed with some downward arcs.

Three such water mills have been made now, but we are only experimenting with this new type of water mill, so only one has been installed.

The installation position of this water mill head corresponds to the middle one of the three small wooden boards installed on the wooden axis.

It is perpendicular to the entire wooden axis.

After finding the right position and installing the water mill head, under the gaze of Han Cheng who was slightly clenching his fists, Mao Er, who also looked very excited, stood up, walked to the side of the water wheel, grabbed a blade on the water wheel with his hand, and pushed it down hard. The water wheel and the shaft fixed to it began to turn.

Also rotating along with it are three relatively thick regular square wooden pillars nailed to the connected wood.

After the water wheel turned half a circle, the top of the square wooden pillar installed in the middle position met the tail end of the high-raised water-pestle hammer head.

As the water wheel turned, this square wooden pillar began to move downward, blocking the tail end of the water mill and being pressed downward by it.

At the same time, the heavy hammer head of the water mill began to rise and rise higher and higher.

"Bang!"

The length of the square wooden pillar is limited. After the tail of the raised water-peel hammer is pressed down a certain distance, the wooden pillar slides to the arc at the back of the tail of the water-peel hammer.

Then it slid down from this arc and turned in another direction.

After losing the pressure brought by the square wooden pillar on the wooden shaft, the end of the water mill with the much heavier hammer head gained the upper hand again, fell from mid-air, and hit the stone mortar below with a "bang".

It had just fallen inside, and after turning a circle, the square wooden pillar turned around again.

With the power it brought, it once again pressed down the raised end of the water mill, forcing it to run downwards...

Han Cheng frowned.

To this extent, the experiment on the new water mill can be said to be basically successful.

However, there are still many small details that need attention and modification.

For example, under the control of the crossbar installed on the rotating shaft, the hammer head of the water mill was not high enough from the ground and fell down.

This is not good.

Because in this case, the impact force of the water pestle is not strong enough, and the efficiency of using it to pound rice is too low.

The reason for this was that the square wooden pillar used to press the tail end of the water mill down was not long enough.

Before it could be pressed to the bottom, it had already slipped off the tail end of the water mill.

"Son of God, I will make another long wooden pillar to replace this short one."

Han Cheng saw where the problem lay, and Mao Er, the leader of the Jinguan City carpenter team, also saw where the problem lay.

So he said this to Han Cheng, and then he walked away holding the axe made of meteorite.

"Wait a moment!"

Upon seeing this, Han Cheng called out to stop Mao Er.

Upon hearing this, Mao Er stopped and looked at Han Cheng with some confusion. He didn't know what his Son of God meant by calling him at this time, or what he wanted to do.

"Don't rush to cut new wood. First, move the water mill towards the wooden shaft and let the tail end of the water mill be closer to the wooden shaft."

Han Cheng said.

It is true that the piece of wood was not long enough.

However, there are two solutions.

One way is as Mao Er said, cut a piece of wood longer than this one and replace the shorter one. In this way, the problem can be solved.

Another way is to move the water mill forward to shorten the distance between the tail end of the water mill and the wooden pillar installed horizontally on the wooden axis.

Reducing the distance is equivalent to increasing the length of the wood.

This is what is called "If the mountain doesn't come to me, I will go to the mountain..."

Hearing Han Cheng say this, Mao Er, who had been a little confused just now, suddenly brightened up.

What the Son of God said seems to be very feasible!

It is more convenient to move the water mill forward than to cut a longer square piece of wood, remove the short one from the wooden axis, and then put the long wood in.

Moreover, if you really want to replace the horizontally installed square wood, it is not as simple as just replacing one piece. Instead, you need to replace all three and make them the same length!

After Mao'er's eyes lit up, he immediately called on a few people to move with him, and the water mill moved forward a little.

Then he asked someone to start the water wheel again.

As the water wheel rotates, the shaft also rotates, driving the small square wooden pieces installed horizontally on it to rotate as well.

The rotating square wooden pillar pressed on the raised tail end of the water mill, and was pressed downwards by the force of rotation.

The tail end of the water mill also began to drop with this force, and the heavy hammer head of the water mill began to rise.

"Bang!"

A moment later, the heavy hammer fell from the air and hit the stone mortar below, making a sound much louder than before.

The sound was of course loud, because the distance the hammer was raised this time was obviously much higher than before!

This means that the proposed changes Han Cheng just proposed were completely successful!

Mao Er looked at Han Cheng who was standing aside with admiration.

The Son of God is the Son of God. He is better at finding solutions than someone like me who deals with wooden objects all day long!

The people standing there watching the new equipment also looked at Han Cheng with eyes full of admiration.

The Son of God is worthy of being the Son of God! He is better at finding solutions than Mao Er, the leader of the Jinguan City Carpenter Group who deals with wood every day!

"Let's go, carry this thing to the water's edge and try installing it there!"

Han Shenzi accepted all the admiring looks from everyone without changing his expression, and said this to everyone.

This water mill must be driven by water after all. There is nothing wrong with people turning it by hand at this time, but to know what the final result will be and whether it works well, we still need to install it by the water and let it be driven by running water to test it.

After hearing what Han Cheng said, the people of the Qingque tribe, who already had enough confidence, sent some people to carry the first upgraded water mill and walked out of the tribe.

Not long after, everyone came to a canal.

There is a bright white stream falling from a high place into the pool below.

This is where the new water mill will be installed.

The terrain in Jinguan City is gentle and the drop in elevation is generally small, so it is not easy to find such a stream.

At the beginning, there was no water flow with such a large drop. It was Han Cheng who had people dig it out here.

The excavated soil was transported to the east side of Jinguan City to fill some low-lying areas.

It is not easy to build such a low-lying area and it requires a lot of effort.

However, there are more people in Jinguan City now, so there is no problem in digging these out.

After arriving here, Maoer and several others took off their shoes, rolled up their trouser legs, and holding a leather measuring tape, went down into the pond to measure and determine the location to install the water wheel.

After a while, the installation location of the water wheel frame was determined.

Then another seven or eight people took off their shoes, rolled up their trouser legs, and came to the shallow pool of water carrying tools such as hoes, shovels, hammers, and thick wooden stakes, and began to install them according to the positions determined by the cat ears.

Not only do more people mean more food, but more work can also be done.

With everyone's efforts, it didn't take too long before the water wheel frame was firmly nailed into the pool of water.

After the rack was installed and fixed, everyone lifted the water wheel and installed it on the rack.

The installed water wheel is on the same plane as the flowing water and is in a vertical relationship.

This allows the falling water to hit the blades of the water wheel, driving the water wheel to rotate...
