"When~When~When~"

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

Cat's Ear, the best carpenter who stayed here in Jinguancheng, was punching a hole in one end of an extremely smooth wooden stick with an axe in one hand and a chisel in the other.

The sticks were so solid that even though the cat's ears were made of one of the few chisels made of meteorite iron in the tribe, they could not dig much wood chips from them.

It is necessary that the stick be solid because it is the outer part of the shaft that exists like a waterwheel.

The production technology of the axle of the Qingque tribe has matured a lot up to now.

It is also for this reason that the axles of the waterwheel, cat ears they did not do anything difficult.

Just use an axle that should have been used on the wheel of the oxcart, and that's it.

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

So the cat ear thought about connecting it at one end of the axle.

The shaft that is connected is not used to bear load, but is only used to rotate with the rotation of the water wheel, so as to drive the movement of the water mill installed below.

Therefore, it is only made of wood, and it will not be tired.

After a while, the long hole in the wood was chiseled.

In this way, three holes were chiseled, and the two adjacent holes were forty-five centimeters apart.

Moreover, the three holes are not in the same line, but are scattered in three different directions of this wooden post.

After the three holes were chiseled, the cat's ears reached for the small rectangular plank that had been cut on the side.

One end of the board is smaller, similar in size to the hole that has been hewn.

The small end of the plank was placed on the hewn hole, and the cat ear picked up the axe and smashed it against the plank for a while, and the plank was firmly fixed to the wooden shaft.

The planks smashed on the wooden shaft were still twenty-three centimeters left.

The cat ear picked up a similar wooden pillar and nailed it firmly into the wooden shaft with the same technique.

After a while, all three holes were firmly nailed into square wooden posts of the same length, width, and thickness.

Because the three are not on the same line, it looks a bit like the mace that the leader of the Red Tiger Tribe is holding in his hand.

After doing this well, the cat ear carefully took it in his hand and checked it, and after seeing that there was nothing wrong, he put it down and went to busy with the rest of the things.

The function of this thing is to dial the installed water hammer head.

A short wooden pillar toggles one.

That is to say, if this water scoop is done well, it can drive three water scoop heads at one time!

Such a tool is not slow......

"Bang, bang, bang......"

The cat's ear, which was holding a meteoric iron axe, continued to swing there.

In front of him was a rough wooden wheel no less than thirty centimeters in diameter and forty in length.

Around this rough wooden wheel, eight lines are evenly divided.

Now, each of the eight lines has been chiseled with three holes about one and a half centimeters wide, five centimeters long, and six centimeters deep.

In the hands of the cat's ears is a trapezoidal plank with a long and narrow top.

On the narrow side of the plank, there are three protrusions that correspond to the holes hewn out of the wooden grunt.

After the cat's ears were aligned, he carried a wooden hammer and struck the end of the plank, slowly nailing it into it and nailing it firmly.

The reason why a wooden hammer was used at this time, rather than a bronze hammer, or a harder meteorite axe, was because the planks were thinner and there was a fear that they would be broken.

In the continuous 'thud' sound, these eight specially made wooden planks were gradually smashed into it, and finally all of them were nailed.

After nailing the eight planks, the thing looked transformed, and the overall diameter reached one and a half meters!

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

After the water wheel was ready, the cat ear, with the help of some people, fixed the water wheel to one end of the bronze shaft.

Once it's fixed, lift it to the ready-made shelf, find a good position, and fix it again.

After these are done, the cat ear grabs a leaf of the water wheel with his hand, and sends it down vigorously (fa, two sounds), and the water wheel turns in the air with a gurgling volley.

Even the solid wooden stick that was attached to the other end of the bronze shaft began to rotate in one piece.

The effect of turning is still good.

After a few spins, the cat's ears got some more oil, which dripped on the connection between the hinge and the shelf below.

Then it began to rotate continuously.

With these large oils for lubrication, the water wheel rotates and is obviously much lighter.

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

Then, instead of letting people turn the water wheel, they will lead people to install the hammer head of the water mill that has been made here.

The hammer head of the water mill that was installed was similar to the original water mill that was being used in the tribe.

They are all shaped like unbalanced balance beams.

At one end is a heavy hammer head, and it crosses the shaft of the wood, which is relatively close to the hammer head, about a third of the way through the entire shaft.

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

Unlike the primitive water mill used in the tribe, this section of the pole is relatively light and long, and it is not pulled out of the sink, but on the contrary, it is scraped extremely flat and smooth.

Moreover, the upper part of its high cocked tail end is not flattened, but people deliberately make some downward arcs.

Three of these water mills have been made so far, but now they are only experimenting with this new type of water mill, so only one is installed.

The position of this water head corresponds to the middle of the three small planks mounted on the wooden shaft.

It has a vertical relationship with the entire wooden axis.

After finding the right position and installing the water wheel, under the gaze of Han Cheng, who clenched his fists slightly, the cat ear, who also looked very excited, stood up, came to the side of the water wheel, grabbed a leaf on the water wheel with his hand, and shot it down hard, and the water wheel and the shaft fixed with it began to rotate.

Along with this, there are three thick, regular square wooden posts nailed to the bodies of the connected timbers.

After half a turn, the top of the square wooden pillar mounted in the middle met the tail of the high raised water hammer.

This square wooden pillar, with the rotation of the water wheel, began to move downward, blocking the tail end of its water mill, and was pressed down by it.

At the same time, the heavy hammer head of the water mill rose and rose further and further.

"Bang!"

The length of the square wooden pillar is limited, and after pressing the tail of the raised water hammer down a certain distance, the wooden pillar slides to the back of the tail of the water mill, the arc that has been made.

Then he slipped off this arc and turned in another direction.

Having lost the pressure from the square wooden pillar on the wooden hinge, the end of the hammer, which was much heavier, gained the upper hand again, and fell from mid-air, slamming into the stone mortar placed below.

As soon as it smashed into it, the square wooden pillar turned around again.

Carrying the power, it once again pressed the tail end of the water mill high and ran down......

Han Cheng's brows furrowed.

The experiment of the new type of water mill can be said to be basically a success to this extent.

However, there are still many small details that need to be paid attention to and need to be modified.

For example, under the control of the crossbar mounted on the top of the shaft, the hammer head of the water mill is not high enough from the ground and falls.

That's not good.

Because in this case, the impact of the water mill is not large enough, and it is used to scoop rice, and the efficiency is too low.

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

Before he could press it to the end, it had already slipped past the tail end of the water mill.

"Miko, I'll make another long wooden pillar and replace this short wooden pillar."

Han Cheng could see what the problem was, and Mao Er, who was the leader of the carpenter group in Jinguancheng, could also see what the problem was.

So he said this to Han Cheng out loud, and then carried an axe made of meteoric iron, and was about to walk to the side.

"Wait a minute!"

Seeing this, Han Cheng stopped the cat's ear.

Hearing this, the cat stood still, looking at Han Cheng with some doubts, not knowing what his god son meant by calling himself at this time, and what he wanted to do.

"Don't panic to chop new wood, first move this water mill to the wooden shaft, so that the end of the water mill is closer to the wooden shaft."

Han Cheng said.

The log wasn't long enough, but it was there.

However, there are two ways to solve it.

One is what the cat ear said, cut a longer wood than this one, and replace the short one, so that this problem can be solved.

The other is to move the water mill forward to reduce the distance between the end of the water mill and the wooden pillar that is attached horizontally on the wooden shaft.

If the distance is reduced, the wood will increase.

This is the so-called mountain does not come to me, I will go to the mountain......

Hearing Han Cheng say this, the cat's ears, who were still a little confused just now, suddenly lit up in front of him.

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

It is more convenient to move the water mill forward than to re-chop a longer square piece of wood, withdraw the short one from the shaft, and then load the long one in.

Moreover, if you really change this square wood installed horizontally, it is not as simple as just changing one, but you need to replace all three and make it the same as the shortening!

After the cat's ears lit up, he immediately beckoned a few people to act with him, and the water mill moved forward a little.

Then he let people start the water wheel again.

When the water wheel rotates, the shaft also rotates, driving the small square timber installed horizontally on it to rotate together.

The rotating square wooden pillar pressed against the high raised tail of the water mill, and under the force of the rotation, it pressed downward.

As the power of the tail of the water mill began to decline, the heavy hammer head of the water mill began to rise.

"Bang!"

A moment later, the heavy hammer fell from the sky and smashed into the stone mortar below, making a loud noise that was much louder than before.

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

That means that the changes that Han Cheng just proposed are completely successful!

The cat's ears were full of admiration and looked at Han Cheng who was standing aside.

The Son of God is the Son of God, and he is more capable of finding a way than himself, who deals with things like wood all day long!

The people who were standing there watching the new equipment looked at Han Cheng with admiration in their eyes.

The Son of God deserves to be the Son of God! is more capable of finding a way than Maoer, the leader of the carpenter group who deals with wood every day and Jinguancheng!

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

Han Shenzi, after accepting all the admiring glances cast by everyone without changing his face, said to everyone in a loud voice.

At this time, there is no problem for people to use their hands, but what is the final result, whether it is good or not, it is still necessary to install it at the water's edge, and let the flowing water drive it to test it.

Hearing Han Cheng say this, the people of the Qingque Tribe, who already had a lot of confidence, separated some people and walked towards the outside of the tribe with the first upgraded and revised water mill.

It wasn't long before they came to a ditch.

There was a bright white stream of water, which fell from a great place into the pool below.

This is where the new water mill will be installed.

The terrain here in Jinguancheng is gentle, and the drop is generally not large, so it is not easy to find such a current.

At the beginning of here, there was no such a large drop in the water, which was excavated by Han Cheng here.

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

Building such a low-lying area is not easy and requires a lot of effort.

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

After coming here, several people took off their shoes, rolled up their trousers, pulled a tape measure made of leather, and went down to the waterhole to measure and determine the location of the water wheel.

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

Then seven or eight more people took off their shoes, rolled up their trousers, and came to the deep pool with tools such as pickaxes, copper shovels, hammers, and thick wooden stakes, and began to install them according to the position determined by the cat's ears.

More people not only eat more bread, but also do a lot of work.

In the operation of the crowd, it did not take too long for the shelf of the water wheel to be firmly nailed to the pool.

After the shelves were installed and fixed, the people carried the water wheel and installed it on the shelves.

The relationship between the installed water wheel and the flowing water is on the same plane, which is a vertical relationship.

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