I am a primitive

After confirming that the molds were completely dry and that the bronze juice could be poured into them, the second senior brother, who could not wait any longer, immediately lit the copper smelting stove together with the rest of the helpers, and poured the copper and tin according to the two The proportion that can be made out of the hardest bronze alloy that has been explored over the years is put into the furnace inside, and then the large-scale wind is turned, and the furnace is constantly fanning the flames...

After the copper and tin in the furnace were completely melted and blended together, the second senior brother took the installed wooden-handled pottery crucible to get the bronze juice from the inside out, and poured it carefully and quickly into the placed mold ...

"Crack!"

"Crackling~"

After the bronze juice had cooled and solidified, Han Cheng, Hei Wa and the others began to smash some molds that could not be used again by violent means.

As the outer molds cracked one after another, the gleaming golden light also emerged from the inside.

Copper rings are small in size and easy to pour. The most difficult to pour are four 1.3-meter copper rods.

Because of the large volume, too much copper juice is required, and it needs to be poured at one time, otherwise there will be faults, which will affect its firmness.

In order to cast these copper rods that will be used as the axles, Han Cheng, Hei Wa, the second senior brother and others spent a lot of effort.

so far so good!

Looking at the four golden copper sticks in front of him, which could become Ruyi Golden Cudgels with some words engraved on them, Han Cheng had a look of rejoicing and joy.

Such a big thing is rarely poured in the tribe. Now that the four copper rods have been poured successfully at one time, Han Cheng is of course delighted.

After confirming that the four copper rods were in good condition, Han Cheng picked up the copper sleeve from the ground and put it on the copper rod.

As a result, the first copper sleeve couldn't fit on the copper rod. In this scene, the face of the black baby was a little green.

Fortunately, the second copper sleeve is just right on top.

These models are all handmade by Heiwa. Even if there are standard sizes, there will inevitably be some errors when making them.

Regarding this point, Han Cheng and Hei Wa had some mental preparations when they started making these, so they directly made twelve copper sleeve molds.

After some tests, nine of the twelve copper sleeves were usable, and among the three discarded, two were too large and one was too small.

However, the remaining nine are enough for use, four axles, one axle with two, and there are still some left.

Lame had already made three large circles at this time, and as for the car bars, those apprentices had also made quite a few.

At this time, after learning that the bronze sleeve was cast, I immediately started to make the inner circle.

As for the cast bronze sleeves, they were directly embedded in the small wooden ring.

In the next few days, the carpenter's room became the most attractive place of the Qingque tribe.

Those minors who ran here when they had nothing to do, weeding the crops in the fields outside, the first thing they did when they came back was to look at the carpenter's room to see how the donkey cart was progressing.

Even if you can't see it, it's good to hear a word or two from others.

"The splints on the wheels are done!"

"The other wheel's sprocket is also fixed!"

"When the cat ear smashed the copper nail on the wheel, it almost hit my hand..."

Under the tireless publicity of these small publicity speakers in the tribe, even without going to the carpenter's room, you can know the progress of the donkey cart.

"Ding ding dong!"

When the last copper nail fixing the car rail is smashed into the wheel, the two wheels are considered to be completely fixed.

Then, under the watchful eyes of Han Cheng, Wu, Da Shixiong and others, Limp and Hei Wa, who seemed a little excited, brought an axle over and put it through the copper ring in the middle of the two wheels one by one. connected together.

After another burst of clanging, the two wheels were firmly fixed on the axle.

"Son of God!"

Lame put down the ax in his hand and looked at Han Cheng, and shouted a little excitedly, and Han Cheng also walked a little excitedly to the front of the wheel with a lot of golden copper nails on it.

Of course Han Cheng was excited, because since he was seven or eight years old, he has never pushed his family's ox cart around the yard for fun, and now he is going back to his old job, how could he not be a little excited?

Han Cheng asked someone to bring some melted animal fat over, poured a lot between the axle and the copper ring, and used it as a lubricant to reduce the friction between the axle and the copper ring.

After finishing, he bent down and held the axle with both hands, and then, under the watchful eyes of everyone in the Qingque tribe, he stepped hard and started the game of pushing the wheel that he would play for a while when he was a child.

With Han Cheng's strength, the two wheels began to roll on the ground.

Dear Son of God bends down to push the cart... In this heroic scene of pushing the wheel, the minors of the Qingque Tribe who watched it all had bright eyes and looked eager to try.

Even the adults in the tribe, watching this scene, had the idea of ​​going on the stage to push it in person.

Because this looks really fun.

Under the envious eyes of everyone, Han Cheng, who pushed the wheel around the open space, stopped.

"This wheel is not stable, it wobbles from side to side when I push it, and needs to be reinforced again," he said.

Under the expectant gaze of the two senior brothers Lie and Heiwa, Han Cheng pointed to the wheel on the left and said aloud.

So the lame people rattled and rattled for a while, reinforcing the wheel.

After doing this for a while, Han Cheng bent down and pushed the wheel of the cart again to conduct the experiment.

This time nothing was wrong.

"Put the body on and have a look!"

Han Cheng, who felt that there was nothing wrong with the wheels, let go of the wheels, and said to Lai and the others.

After waiting for this order for a long time, everyone heard the words and immediately took action. Several pairs of big hands were put together on the body of the donkey cart that had been laid for several days. Without much effort, they lifted it up and put it to the axle.

After a few moves, the round axle got stuck in the groove that had been dug out under the donkey cart.

After moving the car body and making sure that the distance between the car body and the wheels on both sides is the same, following Han Cheng's order, several people started to fix the car body and wheels with leather ropes, sticks and copper nails.

The fixation between the body and the wheels is very important, otherwise the donkey is pulling the cart and galloping on the road, and when the donkey is running happily, the wheels will separate from the body and wander alone.

The donkey was carried by the car body without wheels, and fell on its back in the ditch beside the road...

Thinking about such a picture makes people feel very beautiful.

After a lot of busy work, the body and wheels were firmly connected together.

After confirming that everything was ok, Han Cheng asked people to put the board made of wood on the body, and such a complete deer cart was considered a success.

At this time, the eldest brother had already brought over the tallest and mightiest donkey in the tribe. After seeing Han Cheng nodding, he led the donkey over to harness the cart.

There are sledges, columbine carts, and bronze plows, and people in the tribe are no strangers to similar sets of carts.
