The end of the Ming Dynasty swept the world

Chapter 127 The Machine That Crossed the Era

Zhou Dahu looked at the picture in front of him in panic. He was just a craftsman, and he never thought that someone would take his life so seriously.

But he still stood where he was, and didn't say yes, just a little dizzy.

"You, you." He was a little excited and incoherent.

At this moment, someone in the room suddenly sternly said: "You bastard, you always say that Daming doesn't pay attention to firearms on weekdays, so you can't use your skills to the fullest."

"Right now, our people are suffering from wars and chaos. The soldiers of Ming Dynasty are waiting for your skills. How long do you want to hide in your dilapidated iron shop?"

"If you don't go, I will take my son."

A young woman, with a child in her arms, came out of the house.

The woman looks pretty good, she looks like she is in her 20s, and the child is still young, two or three years old.

The clothes she wore were very simple, but her behavior was not like that of ordinary folk women. She had a distinctive aura, as if she was from a great family.

It was Zhou Dahu's mother-in-law Zhao Shi.

Zhou Dahu rubbed his hands in embarrassment: "The child is still young, so I am not for the child."

"Do you want the child to live in this broken iron shop like you in the future?" Zhao said angrily.

Zhou Dahu had no choice but to stomp his feet: "I'll go, it's okay if I go."

Ding Yi was ecstatic, and hurriedly said, "Thank you sister-in-law."

It turns out that this Zhao family is actually the daughter of the Zhao family, the little granddaughter of Zhao Shizhen (the youngest daughter of the second son).

The two had known each other since they were children. Zhou Dahu learned firearms from his father in the Zhao family, and the Zhao family was also in the Zhao family.

The two were childhood sweethearts and grew up together. Later, the Zhao family fell, and the Zhao family followed Zhou Dahu to maintain the iron shop together.

Mrs. Zhao is not only literate, but also proficient in the spectrum of artifacts. Zhou Dahu learned many skills from Mrs. Zhao.

It's no wonder that everyone sees that her aura is different from that of ordinary women. Now Ding Yi has won another treasure.

Now that the Zhao family came forward, Zhou Dahu quickly compromised and agreed to return to Lushun with Ding Yi.

Now that they are their own people, the couple took Ding Yi into the house inside.

Once inside, everyone gasped.

There is already a modern atmosphere here, and there are all kinds of machinery and firearms everywhere, many of which Ding Yi has never seen before.

Zhou Dahu first brought Ding Yi to a machine made of wood and steel.

"This is called a drilling machine. It was made by our grandfather during his lifetime. Two machines were made that year. One was sent to the Ministry of Industry and later destroyed by the Ministry of Industry. The other one is this one. Although it has been a long time ago, it can still be used."

This is a machine that spans the ages, with a drill press made of clam wood and fine steel.

Mrs. Zhao quickly explained to Ding Yi.

Clam wood, also known as fire wood, is a national second-class protected plant in modern times, and its main branches are in tropical regions such as Guangxi and Yunnan.

Clam wood is dense and heavy, it sinks in water, it is as hard as steel, and when knocked, it makes a steel-like sound. It is very difficult to cut and process. Even in modern times, nails are difficult to drive in. In ancient times, they were called Invulnerable wood.

But once processed, it is as durable as modern steel products.

Ding Yi's eyes lit up when he heard that, if this thing could be processed into shields and armor, it would be great.

In ancient times, this kind of wood was generally used to make mechanical skids, wooden axles, hand planers, and special parts for shipbuilding.

In modern times, it is mostly used as a cutting board.

According to Mr. Zhao, the whole body of the machine tool is made of clam wood and fine steel. It took half a year to make, and it is durable.

The drill bit is made of Su steel and tempered five times, which can be used to drill the gun tube.

Moreover, according to Zhao Shizhen's experience, he can only use Su Steel and refine it five times. If it is tempered too much, it will become brittle and easy to break. If it is tempered less, it will not be hard enough. This is the result of Zhao Shizhen's many experiments.

Each drill bit can drill [-] gun barrels, and after grinding, it can be used again, which is very convenient.

When drilling the blunderbuss pipe, hydraulic power or manpower can be used.

Water power is relatively easy, but manpower requires a lot of strength.

If manpower is used, only five holes can be drilled a day.

Zhou Dahu said at this time: "If there are many people, if you change the drill, you can drill more roots."

He showed Ding Yi the drill bit. The diamond was as thick as a finger and half a meter long. After the front was worn out, it could be polished again, which was very convenient.

Because the drill bit is long, you must be careful when drilling, otherwise it is easy to break, and someone needs to keep adding water.

Ding Yi took a closer look at the drilling machine, and found that the design was ingenious.

On the left there is something like an inlay, which can fix the gun barrel, and on the right is a drill bit, which can also be fixed to ensure that it will not deviate outward.

Because the gun barrel is longer, the two-side drilling method is used.

That is to drill one side first, then turn the gun barrel around, and then drill the other side. After drilling both sides, it is penetrated, polished, and corrected.

There are also smaller and thinner drill bits for penetration.

The most amazing thing is the shape of the gun barrel, which is completely indistinguishable from modern machine tools.

Zhou Dahu made the gun barrel. Firstly, the stainless steel is randomly punched into a square or rectangle, and then fixed on the drilling machine, and then the hole is drilled. After the hole is drilled, another thicker and shorter head is used. round.

Ding Yi and the others also watched a small demonstration. Except for Ding Yi, everyone was astonished and full of praise.

The set head is placed on the side, and the machine tool rolls the square barrel, rolling it at a high speed while sending it forward.

The file didn't move, whizzing, the steel shavings fell like rain, and the square gun barrel soon became round, completely no different from modern chances.

What a fucking talent, this is a simple version of the lathe, Ding Yi looked at this advanced design, and cast all his heart on Zhao Shizhen. of? I suspect that he is time-traveling."

time travel?Everyone was at a loss, not knowing what it meant.

Mrs. Zhao said with a smile: "My grandfather didn't invent this machine tool, it was my dad who invented it, and he also learned it from other places."

In the 43rd year of Wanli (1615), Zhao's father participated in the Zhejiang Provincial Examination and won the top five in the province. In the autumn of that year, he went to Beijing to participate in the next year's Bingchen Division re-examination.

In the capital, I met Song Yingxing from Jiangxi who came to try again.

Both of them are interested in firearms machinery. Song Yingxing pointed out that Daming is too slow to make guns now, mainly because the grinding and manufacturing of gun barrels accounted for more than half of the time. The material is difficult to grasp.

Father Zhao was overjoyed when he heard this, but he asked Song Yingxing for advice and learned the model of the machine.

But it was not complete at the time. Father Zhao later thought too much about it and failed the exam. Song Yingxing, who was in the same period, did not know that he was also influenced by him and failed in the same way.

Song Yingxing refused to accept it, and went back to prepare for another exam. After failing the exam again in 1619, he finally gave up the idea of ​​taking the exam.

In the autumn of 1616, Father Zhao, who came back, finally made a machine tool after many attempts and transformations. It took a year.

The first machine tool was dedicated to the court, but it was shipped to the capital after a year in Zhejiang. After the Ministry of Industry read it, it issued an official document to promote it, and then threw it into the warehouse, where it was destroyed within a few years.

Zhao's father spent another half a year re-making one at home, and it was more complete, which is the one in front of him.

But because he was not valued by the court, Zhao's father, like his father Zhao Shizhen, also died in depression.
