MTL - Be a Leader In a Primitive Tribe-Chapter 120

For Mei, it is not difficult to build a carriage after understanding the design principles.

In fact, it is the process of splicing.

Two wheels plus a rotating shaft, the board is mounted on it, and the horse can be pulled away.

The difficulty lies in how to make the wheels stronger, and what material the shaft uses to be more durable and smoother.

She took a few colleagues from the research and development team, but it took three days to manufacture the carriage.

And lead the horse over, put on the cart and walk around, observing while walking.

Then improve it.

For the large waterwheel that was just completed some time ago, they directly transferred the design of the bearings to use when building the carriage.

Sang Yu also came to have a look at the first time. From the shape and structure, there is nothing to choose. The main problem is the bearing.

"Mei, I'm afraid this bearing needs to be improved, pig iron won't work."

"But the tribe's current hardest material is iron. If iron can't be used as a bearing, then even if we use the hardest wood, it may not last long."

"The strength of pure iron is sufficient, but the bearing material not only has the requirements for strength, but also the requirements for elasticity and toughness. The toughness of pure iron is too poor, and it is easy to break. It is not the best material for bearings." ①

After hearing this, Mei looked worriedly at the large water trucks outside.

Of these waterwheels, two of them use iron as their bearings.

Sang Yu knew her worry, and said, "For the time being, we can hold on for a while, but we still have to switch to other materials, and that is steel."

"steel?"

In fact, Sang Yu doesn't know much about the principle of making steel. So when I was making the big waterwheel, I also temporarily defaulted to her approach.

It’s just that a few days ago, while taking Shao Rong and the others to the yard, the word “smelting into steel” suddenly popped up. At this moment, it seemed like a switch was turned on in my mind.

Iron is versatile, ductile, and hard and strong. But iron has an obvious disadvantage. It is easy to rust once it encounters humid air, and its toughness is not good.

Steel is different. It is also very strong, with higher wear resistance, toughness, and corrosion resistance. It is the core material of the key parts of the machine.

Therefore, the best material for this part of the bearing is steel.

"Steel is better than iron, harder and more wear-resistant than iron."

Mei and the others were full of curiosity about this steel moment.

"Does the leader know how to forge steel?"

"Actually, in the process of blacksmithing, we occasionally obtained things like steel."

The biggest difference between steel and iron is that the manufacturing process is different. The carbon content in steel will be less than 2%, but the carbon content in iron is higher than 2%.

Shen Kuo in the Song Dynasty recorded in "Mengxi Bi Tan": "But if you take rough iron and calcine it with more than a hundred fires, and call it every time you calcine it, until it is tired and calcined without losing weight, then pure steel will not be consumed even after hundreds of smelting."

The production process of Bailian Steel is actually heating iron to a certain temperature, and then repeatedly forging to remove impurities in the iron, so that its structure and composition become more uniform and dense during the forging process. ②

"Come on, let's go to the blacksmith yard."

Mei and the members of the research and development team quickly followed Sang Yu's pace.

After arriving at the blacksmithing ground, Sang Yu said directly to the tree, "Which iron tools have you been hammering for the longest time?"

Without further ado, the tree brought them to the two forged iron beds at the head, and said: "These two forged irons are connected to the water drain. Once the power is connected, the two big hammers on it will continue to move regularly. As long as the power is not turned off, it will never stop, and our workers only need to keep turning the red-hot iron block to adjust the plasticity."

"So, the iron objects made on these two iron beds were not only beaten a hundred times?"

The tree smiled and said, "There are thousands of them."

"Is there any difference between the ironware made of these two iron beds and others?"

"It is smoother, more flexible, and not easy to rust. The iron surface of other iron beds is relatively rough, and there are such large and small particles on it, and it will rust when it touches water."

As Shu said, he quickly pulled over the workers in charge of the two machine tools and asked them to introduce their craft to Sang Yu.

And these workers in the blacksmithing yard have been staying here from the beginning, and gradually understand the properties of these irons.

Because of the support of the water row, blowing and hammering do not require power, which saves them a lot of effort. They found that the more forged the iron block, the harder and better the quality.

So they continued to forge. Under the continuous beating, the iron sheet continued to extend. They folded the iron sheet and continued to forge. After quenching, it became a peerless tool.

As the two workers spoke, they compared the ironware they usually forged with those of other machine tools. Sang Yu looked at the results with obvious differences in front of him, and at this moment he understood in his heart that the ironware forged by these two iron beds block, already close to the level of steel.

Although the process is more complicated and time-consuming, the core materials used to make some machines are worth the effort.

So she explained the principle of steel to everyone, let the two iron beds start to make bearings, and later replaced the wooden and iron bearings on the waterwheel, and used them in the production of carriages and vehicles.

"On the basis of the original forging, it has to be hammered continuously to ensure that it can reach the quality of steel."

"The long round shaft needs to be replaced with steel, and the bearing is near the wheel. Two steel rings should be made, a large ring and a small ring, with steel **** in the middle. This design can better support the rotating body. At the same time, it can reduce the frictional resistance, and I will draw the blueprint later, and you can make it and do it.”

After confirming that the tribe's steel can be made, Sang Yu opened his mind, and soon remembered the bearing structure seen in modern times.

Once such a bearing is made, it means that all the power equipment of the tribe can be developed on this basis in the future, and the mechanical movement resistance and problems encountered before will be easily solved.

Mei and the others were once again shocked by Sang Yu's design concept.

"When the bearing is installed, lubricant must be added. Previously, we used animal fat to lubricate. For now, we can use this for now. When we have time later, we will gradually refine other better substitutes."

"When the carriage work is done, replace the ten blacksmithing machine tools in the blacksmith yard with automatic water drainage power as much as possible to reduce manual physical expenditure."

This equipment is bound to take a long time, but it will save a lot of effort in the future.

Mei and Shu knew the importance of this matter and took orders immediately.

"The matter of the waterwheel needs to be further improved, and Mei will make specific arrangements for you."

"It's the leader..."

The tribe has steel. Although it is less, it can at least solve the problem of core materials. Sang Yu feels like he is stepping on a cloud.

The think tanks of the handicraft team did not disappoint Sang Yu at all.

It took about three months to build the tribe's first and second carriages.

One for people and one for cargo.

The one carrying people has a roof, like a small house.

The wood used is as light as possible to reduce the load on the horse.

For cargo, it is only necessary to surround the perimeter of the floor with a guardrail so that the cargo does not fall off.

Sang Yu personally inspected their newly designed bearings. Exactly the same as modern ones, the car is in motion.

Whether it is forward, backward or turning, it is particularly silky, which makes her breathe a sigh of relief.

"Today, I will use these two carriages to send some food to Tongzhen. As for the one carrying people, Mei, you and your research team will go together, as well as two blacksmiths, to experience this carriage." The car, if you find a problem, correct it in time.”

"It's the leader..."

Mei and the others were eager to try it, although they had ridden in this car during the test.

But it takes long-distance driving to really experience the actual situation of the car.

According to the fact that a horse can pull two thousand catties of goods, Sang Yu asked them to load a thousand catties of grain after excluding the weight of the cart and wheels.

As for those who pull people, one person weighs about a hundred catties, and five people weigh only five or six hundred catties, which is not too much weight.

Now that the steel bearings are installed, with a swipe of lubricating oil, there is no hindrance. Even a person can be dragged for a few steps, let alone a strong horse.

But just in case, she asked them to have three more horses to keep up with them in case of emergency.

So two carriages, loaded with people and goods, drove towards Tong Town one after the other.

The roads inside the tribe have been repaired a long time ago, and there is no obstacle when the carriage passes by, but the wheels are made of wood, and the outside is only covered with a layer of animal skin. There is a lot of room for improvement in terms of shock resistance and cushioning, so the people sitting on it But not that comfortable.

But it can still sit, at least in terms of load and speed.

The main thing is to be able to pull.

In the past, a horse could hunch two hundred catties at most, and the horse would get tired easily after long-distance walking. But now it can pull more than 1,000 catties without a load, which is eight to ten times as much, which greatly increases the load capacity.

For two carriages, only one person needs to be in front to steer the direction. The others are laughing and chatting in the carriage, feeling pretty good.

Yun, Ting, and two other steel forging workers were particularly excited. They hadn't been out since they came to the Phoenix Tribe. Now is the chance to go outside, like a bird set free.

"This car is really convenient. One person is on the road, and the others don't have to worry about anything, just wait to get there."

"It's just a little assy."

"Hahaha-"

"You say, can we change the chair to a softer one next time, so that it won't cost your ass, and maybe you can sleep in the car."

"The **** doesn't hurt anymore, but the car shakes badly."

"I'm afraid I still have to find a way to improve the wheels. I don't know if there is anything that can bounce and soften to reduce vibration."

"I've never seen anything like this."

"Why do I think the leader knows."

"Impossible, the leader knows why he won't tell us."

"Maybe I can't remember it, or we don't have this material in Donghuang, so it's useless to say it."

"The leader's head is like a treasure chest, you can get whatever you want."

"It's not just a hundred treasures, it's a thousand treasures."

After walking for an unknown amount of time, the car stopped suddenly, and there were voices coming from outside the car. Several people probed out to have a look, and they turned out to be old acquaintances.

Mei leaned out and shouted to the woman on the horse in front, "Ya—"

There were a few people behind Ya, who had just seen the small red flag of the Phoenix Tribe on the carriage, and felt kind. Now that it was Mei, the surprise on her face couldn't be hidden. The two sides immediately stopped the horse and the carriage, and got off the carriage. Reminiscing about the past.

"Okay, you guys, when did you research this thing again, and it can hold so many people and so many things."

"This is called a carriage. It has just been developed. We are the first group of people to sit in a carriage. The leader asked us to take a ride to see if there is any improvement when we go back."

"Okay, I haven't been to the Phoenix tribe for a few months, and your new things are one after another. But this thing is also very useful. If you pull it to us to install stones, you can save a lot of people and horses at a time."

"Yes, this carriage is specially researched to transport goods."

"No, I'll have to ask Sangsang to build me some later."

Mei smiled, this is not something they should consider.

"Has the road from the Alliance Center to the Rock Horde been repaired?"

"Soon, there is only a small tail left. After a year, after a rest, it will be unimpeded."

"That's great, the road has been repaired, and with the carriage, it will be much more convenient to travel in the future." Ting couldn't help interjecting.

"It's much more convenient, so I wonder if Sangsang had already planned to build such a car when she said that she wanted to build roads."

Mei and the others looked at each other and smiled. It's really not good to say that the treasure chest is the leader of the family.

"Then you come here this time, when will you go back?" Mei asked.

From the beginning of this year to the end of the year, I haven't seen Ya for a long time, and in her heart, she actually misses her a lot.

And Shao Rong misses her mother very much.

"Stay a few more days. Are you going to Tong Town? When will you be back?"

Ya also hurriedly inquired. If Mei is not in the tribe this time, she will feel lost.

Mei knew that she wouldn't leave right away, so she felt relieved, and then said with a smile: "I'm here at night, and I'm going back to the new place tomorrow morning."

Ya looked at her delicate face with burning eyes.

Nodded: "That's fine, I won't delay your journey, be careful on the way, I'll go to Xindi first, see you tomorrow."

"See you tomorrow-"
