From Chief to Ball

The eight arcs spliced ​​outside are rims, or rims.

The interior also needs to connect the hub and the rim with spokes, the hub is easier, just use a log saw to dig a hole in the middle.

Except for the guy who was trimming the rim, everyone else was given a spoke-length rope to grind one spoke each.

The connection still depends on mortise and tenon, and the two ends of the spokes are engraved with tenons to ensure that the length of each spoke is the same as much as possible.

Within a few days of waiting for the rims to dry, Chen Jian and his clan finished the body frame of the cart.

This is much simpler. It is no problem to use isinglass and mortise and tenon. The axle also chooses an iron birch without boils, and the width of the shaft rod is based on a cow.

In addition, Chen Jian asked someone to tie up a few gelding oxen, and made some nose rings with iron.

Cows must wear nose rings, because cows are not very obedient, and in most cases they bow their heads like children, but once they go crazy, even a few people can't stop them.

The nose ring is easy to wear. After tying the cow, touch the softest and thinnest part of the cow's nose with your hand, align it, and pierce it hard. .

After the nose ring is put on, the harness and the ox harness are prepared. The ox relies on the strength of the neck, and the ox harness is a triangular curved piece of wood that is stuck on the back of the cow's neck.

The wooden saddle is placed on the back, wrapped around the girth, and the weight of the car will be supported by the wooden saddle on the back in the future.The harness on the cow's neck only provides forward force, which is a more scientific approach, allowing the cart to pull more things.

Now that the follow-up is ready, all that remains is to wait for the most important wheels.

After a few days, the bent wood finally dried.

Carve a mortise on the connection surface, use a shorter wooden stick as a double-ended tenon, and coat the inside with isher glue to glue the two rim arcs together.The length of the double tenon is exactly equal to the length of the two mortise eyes, ensuring the seamless connection of the two arcs.

The last one couldn't be used with mortise and tenon, so it was directly covered with fish maw glue and stuffed into the last missing piece of pie.

Use the punched iron curium to hook and fix it, and then wrap a layer of copper skin on the outside, and the entire rim is completed.

The inner arc of the rim is carved with mortise holes to connect the prepared spokes with the logs used as hubs.Even if the two simple wheels were completed, it took twenty people and seven days. Chen Jian looked at the arc that was not too round, and he was still very satisfied.

Although it is very rough, the tribe has been preparing for these two wheels for too long.

From metal to isinglass, from rulers to compasses, from conquest of slaves with off-the-job workers to weaving nets and fishing with plenty of food... everything is indispensable.Only by experiencing it personally can we know the greatness and wisdom of our ancestors in previous lives.

Chen Jian picked up a wheel with emotion and tried it. It weighed twenty or thirty catties, which was very heavy.

It is recorded in "Historical Records" that Lai Ai, a native of Qin, was able to put the wheels underneath and stand up, and thus won the favor of Zulong's mother.Although the Great God Sima Qian didn't have that kind of thing, let alone practiced it, it may be credible.

After being slightly jealous of Lao Ai, Chen Jian looked at the two wheels and thought that flesh and blood could stand up and support them, so the axle should be fine.

At this time, there was no ball bearing, and it was impossible to make it at all. If you want to make the wheel turn, you can only dry the shaft, and the damage rate is extremely high.

Fortunately, the tribe now has copper and iron, and the place where the wheel is placed on the axle is covered with thin metal. The sides of the wheel are fixed with wood and iron hooks, which are higher than the diameter of the wheel eye to prevent the wheel from running around.

After it was wrapped, it was the metal that rubbed against the fragile wood, and after turning it a few times, it made a squeak that made the teeth sore.

I found some animal fat and spread it between the wheel and the axle as lubrication.It is said that castor oil and whale oil are good natural lubricating oils, but there is no castor plant near the tribe, and the tribe has never even seen a larger lake, let alone the sea.

After smearing the grease, a brand new cart appeared in front of the tribe. They found the biggest and most obedient gelding, and put on the harness prepared in advance. The gelling had never pulled a cart before, so it was very unaccustomed and dissatisfied. Turning around, not wanting the harness around his neck.

The clansmen in the city came to watch one after another, and the children clapped their hands and sat on the bullock cart in a swarm.

Chen Jian broke a willow branch and sat cross-legged on the pole just like the car owner in old movies, whistled, shook the willow branch, and shouted: "Drive!"

The old scalper turned his head and looked at Chen Jian blankly, completely unable to understand what Chen Jian was shouting.

Amidst the laughter of the clansmen, Chen Jian jumped out of the car in despair, took the rope tied to the nose of the cow, and walked forward.

Chapter 66 Sunny Day

Since that day, the sound of squeaking and twisting wheels began to echo in the wheat fields, singing another soft sound, like the spring cry of wild cats at night, which tickles people's hearts.

The children couldn't put their hands down on the new toys they got. They were still young and couldn't hear the rhythm of the creaking sound, so Chen Jian would always hide away.

Yu Qian'er always leads the ox cart, which is filled with cold, honey-melted water just poured from the stream, and sends it to the clansmen who are still working in the fields.

Whenever the people of the tribe came back from fishing or hunting, she was always the happiest. She drove the car over and put the baskets of fish and prey on the car, and let the people sit aside and shake them gently. With the whip, let the hard-working cows bring these harvests back to the village.

The best toy for children, they always like to show it to others, hoping that others can share their happiness.

For her, she was still a child when she rode around in a bullock cart.

When I got out of the bullock cart and returned to the meeting hall to count how many fish I caught and how many birds I caught today, I was no longer a child.

All the things in the village that needed to be counted and distributed were all on her shoulders. She knew what her brother was busy with, so she didn't bother, but secretly sighed that she couldn't help.

Everything in the village was as usual. The riders who traveled along the river had only left for ten days and hadn't returned yet, but it was coming soon.

Except for fishing and hunting, the men in the clan stopped all their work and were preparing for the first harvest.

Now the wheat has turned yellow, and the pea flowers are in full bloom. I had boiled pea pods in salt water for dinner once. It tasted good, but it was worse than wheat rice.

Looking at the yellowed wheat rice, recalling the taste of a few months ago, Chen Jian led them to start the last busy.

The meteorite iron weapons captured in the last victory were all used to make agricultural tools or curiums. With the immature iron smelting technology, there is no advantage in using them as weapons or bronze, but it is much better to make agricultural tools than brittle bronze.

Sickles, chisels, saws, hoes, sledgehammers... more than 60 men are busy in front of the charcoal stove every day, making ugly, but at least more useful than stones.

After Chen Jian looked at it for two days, he took the remaining one hundred and ten people outside the village and chose a venue as the future yard.

After the wheat is harvested, it needs yards and wind to thresh. A flat ground was delineated, and it took three days to remove the weeds and tamp it down.

Forty people were left behind, and the rest went back to the warehouse area of ​​the city to build houses. It was impossible to stack the harvested wheat beans outside, and conical granaries rose up one after another.

At this time, the inside is still empty, but people believe that it will be filled with wheat beans in a short time. When you want to eat, you don't need a woman to go outside to collect it, just reach out and grab some.

The women are also preparing for the harvest, weaving sacks out of thick twine, not so fine, each can hold about two hundred catties of grain.

The forty ones who followed Chen Jianjian were busy with another matter. Chen Jian said that after the harvest, they would cook a better meal than wheat rice, so they began to look forward to it.

Wheat rice is a last resort. There is no stone mill, the wheat cannot be peeled, and it can only be crushed and steamed. The rough bran is actually hard to swallow, but it is finer than the food eaten before.

Stone grinding is not difficult, there are chisels, hammers, and rope cutting, and it is only a matter of time before stone grinding is done.

The difficulty is the power of the stone mill, and the few donkeys returned may not be enough. After the wheat matures, the entire city will have a population of nearly [-]. Of course, it will not work to rely on a few blindfolded donkeys, the speed is too slow.

When Chen Jian thinks of stone mills, he naturally thinks of mills, and when he thinks of mills, he naturally thinks of windmills.

It is not the horizontal windmill of the Dutch business card, that kind of difficulty is too high, and it can be made at the current level of processing. A helical gear transmission can make the tribe collapse by converting the vertical power to parallel power, and the center of gravity is also a big one. question.

But in the memory of the previous life, Huaxia also had windmills, and they were completely different from that kind of windmills, with a strong Chinese style.

Chen Jian remembered the scene in the old movie "The Story of Liubao", and the popular episode "Nine Nine Sunny Days". The squeaking windmill, as a metaphor for the whole song, runs through the whole song.

This kind of windmill was once located in the land of northern Jiangsu and the Changlu Salt Field. Before the death of the Ming Dynasty, it left a deep impression on the Dutch who came by boat.
