The end of the Ming Dynasty swept the world

Chapter 128 Leave it to us husband and wife
It turned out to be Song Yingxing, and Ding Yi was overjoyed again, but he vaguely remembered that during this period, Song Yingxing was still teaching in his hometown Jiangxi because he failed the exam.

There is no time to go to Jiangxi right now, and it is when he is writing a book. When he comes to Zhejiang in the future, I will come to him again.

Even if people don't want to come, it's good to get all the books he has written in the past few years.

Most of Song Yingxing's works in history were written during this period when he was teaching in his hometown.

"What is this for?" Ding Yi pointed at the fine steel chains on both sides of the machine tool and the huge fan-like steel sheets.

"It's hydraulic. Our family puts the machinery in the house, and there is no waterwheel, so we can't use it."

Zhou Dahu continued to explain to Ding Yi.

This machine tool can also use hydraulic power, which saves time and effort, but has higher requirements.

First of all, a huge waterwheel is to be built, and a reservoir is built on the side. The waterwheel is connected to the reservoir and forms a cycle, and the water pumped up returns to the reservoir.

The intermediate shaft of the waterwheel is used to connect the drill bit. When the waterwheel rotates, the intermediate bearing of the waterwheel will drill with the drill bit. It does not require manpower, and it does not require people to add water. It is very easy. With one person, you can Look at a dozen of these waterwheels.

The only function of the human body is to remove it in time when drilling through, and just change the face.

The steel sheet is used to increase the resistance of the water to slow down the waterwheel, and the iron chain is used to temporarily stop the waterwheel to remove the drill bit and the drilled barrel.

What's even more awesome is that on the left and right sides of each waterwheel, one machine tool can be placed on each side, and the bearings can be connected at the same time, and two can be drilled at the same time.

"It's wonderful, it's really wonderful, it's too wonderful to describe." Listening to Ding Yi, he was overwhelmed. The machine tool jointly invented by two masters, Song Yingxing and Father Zhao, can be called a cross-age technological product.

The more he watched it, the more he liked it. He wished he could make a hundred of them right away.

Ding Yi carefully touched the machine tool, and asked in a deep voice: "Do you still have the blueprint for this, can you still make it?"

"Of course, clam wood is hard to find. You have to go to Fujian and Guangdong to find it." Zhou Dahu said.

And it is very difficult to make, because the clam wood is super hard, and the middle bearing of the machine tool, including the middle bearing connected to the water wheel of the machine tool, must also be made of clam wood.

"How much clam wood is used for each machine tool, plus the waterwheel?"

Zhou Dahu looked at Mrs. Zhao, Mrs. Zhao thought for a while, "At least twenty loads."

Mrs. Zhao used the weight to calculate, and the clam wood was very heavy. Later, Ding Yi and her estimated it, and it was about one cubic meter in modern times.

The quantity requirement is not high, one old clam wood can make several machine tools.

But the key is that this thing is a bit difficult to process.

Ding Yi touched the machine tool and looked around for a while.

Seeing this, Zhao Dashan imitated Ding Yi and wanted to reach out to touch it.

"Get out." Ding Yi quickly slapped his hand away: "Get your stinky paw away, this is our most important treasure in Lushun."

Zhao Dashan chuckled, and retracted his hand in embarrassment.

Zhou Dahu and Mrs. Zhao listened with joy in their hearts, and their eyes were quite smug. After all, Zhao Shizhen and Zhao's father didn't pay much attention to the court. I didn't expect that the Du Si in front of me would pay so much attention. Although the official is a bit small, he is quite accomplished. no.

After looking at it for a while, Ding Yi said cautiously: "Actually, I checked, can many parts be replaced by fine steel instead of clam wood?"

For example, these six brackets (this machine tool uses six brackets for stability, which are also clam wood.)
"Cast iron can also be used, which is less expensive to build and more stable."

Mrs. Zhao was stunned for a moment, and after looking at it for a while, she nodded again and again: "My lord said that my father used the leftover clam wood and didn't want to deal with it, so he made a bracket. In some places, it can be replaced with refined steel or cast iron. of."

The two also greatly admired Ding Yi, they didn't expect him to observe so carefully.

Zhao Dashan thought on the sidelines, Ding Tou is the best brain, he understands everything, he can say a few words about everything, even if he refuses to accept it.

Then Zhou Dahu introduced several firearms to Ding Yi, all of which were invented by Zhao Shizhen back then, but most of them are flashy, some require high manufacturing requirements, and some are more useful, and they have basically never been used in the court.

Ding Yi watched happily, and waved his hand: "Take them all away, and we'll talk about them when we return to Lushun."

Zhou Dahu and his wife knew a lot of things. After a while, Ding Yina finished talking to them, and now he was about to take him away. Now everyone helped them move.

All firearms, drawings, books, including machine tools must be taken away.

The machine tool was even more careful, for fear of bumping into it.

On the way back, Zhou Dahu seemed to think of something, and said loudly: "Master Ding wants to fight the Tartars, but he has to make cannons. I don't know much about cannons, but my senior brother Wang You'an, who followed my father and others by his grandfather's side, mainly attacked It’s artillery, and I have been in the Artillery Bureau of the Ministry of Industry for five years.”

"I got him on board a long time ago. Hahaha." Zhao Dashan laughed.

Zhou Dahu disturbed his head and smiled foolishly.

On the boat that night, Ding Yi and their husband and wife, including Wang You'an and others, talked by candlelight and humbly asked for advice on firearms.

Zhou Dahu and Wang You'an belonged to the same family, and they both worked under Ding Yi in the future, but they didn't hide it, and basically answered every question.

Ding Yi specifically asked how to improve the range, rate of fire, and small field artillery.

All three of them put forward their own opinions, especially Mrs. Zhao, regardless of her being a woman, she had the most literacy and the most theoretical knowledge, and she also put forward many important opinions.

During the day, they saw Ding Yi's improved granular gunpowder and custom-packed paper-wrapped bombs, and they were quite impressed.

According to them, the barrel made of drilled guns has a longer range and more times of use.

Such power is already the strongest in this era.

To improve, we can only produce bullets as Ding Yi said.

But today's technology is unrealistic.

That only improves reload speed.

Ding Yi's fixed paper-packed ammunition has already improved the reloading speed. If you want to go faster, you can only shorten the reloading steps and reduce the corresponding parts.

The original loading steps of the Lumi blunderbuss were five steps, which was proposed by Zhao Shizhen.

They are: pouring gunpowder, loading gunpowder, loading solid medicine, setting door medicine, and lighting matchlock.

After Ding Yi improved the custom-packed paper-packed medicine, he poured the door medicine first, and then poured the gunpowder.

There is no difference in the order of these steps, that is, after pouring, you need to turn the gun sideways, and then tap it down lightly, so that the powder enters the eyes and connects with the medicine in the gun.

Ding Yi meant, can you think of a way to improve a part, after the door powder and the gun powder are poured from different directions, there is no need to turn the gun and knock again, just pull it out lightly, and they can be connected together, which can save at least five dollars. seconds.

Sometimes on the battlefield, in order to prevent the two medicines from being connected, the soldiers still have to take a look, lest they fail to connect, it may take ten seconds later.

Mrs. Zhao and Zhou Dahu listened and looked at each other. After a while, Mrs. Zhao said in a positive tone: "Leave it to us husband and wife, Mr. Ding, please rest assured."
