Daming: My boss Zhu Yuanzhang

Chapter 22 Build a generator first
Li Wei watched the craftsman just circle the empty field a few times and asked him to stop.

The obvious problem with this tricycle is that the friction of the rotating shaft is too large, and the gears are relatively bulky, resulting in a heavy body and slow travel speed.

It's easy to make improvements. Just make the bearings and replace the gears with chains. Some places also need to be lubricated. There are no substitutes in this era.

"Okay, I understand this, what else is there?" Li Wei asked.

"Sir, in addition to this, there is also a repeating fire gun, but we can't make a repeating fire gun. We just use flint to replace the previous ignition."

"Oh? Isn't that a flintlock gun? Come and take a look at it!"

Li Wei said in surprise, who among men doesn't love guns?It's just that due to legal reasons in his previous life, he never touched a gun. Although he often saw those crackling gunfight scenes in many movies and TV shows, he could only covet them.

In fact, it is not difficult to make a gun. As long as you have a machine tool and suitable steel, you can make it even if it is just a little bit difficult.

In the previous life, guns were banned only after ninety years. Before that, there were many small workshops that could make guns, and some of them were not much worse than the official ones in terms of craftsmanship.

After all, the gun is just a mechanical device. As long as there are blueprints, it can be made by any mechanical processing factory. It is just a difference between better and worse.

Li Wei felt that the main difficulty in making a gun like that of later generations was nothing more than special steel and the most important thing: smokeless gunpowder!

That thing is really not easy to make. He watched a video that explained in detail the production of nitrocellulose, also known as nitrocellulose, and the process of making it into smokeless gunpowder for military use. Its history is very bumpy. It took several major accidents before it was finally successful.

This thing couldn't be touched easily, and he didn't want to die if he tried it.

Following Fang Jianbao to another venue, Li Wei saw the Suifa gun they made. It was very different from what he had imagined. The body of the gun was still the same as the old-fashioned firecracker. The barrel was thick and thick, but A hole was opened at the back and a firing device was designed, but there was no medicine tank cover and the sealing was poor.

"Look, sir, as long as you pull the button here, the flint will bounce down and collide with the fire sickle to produce sparks, which will then ignite it and launch it."

Fang Jianbao introduced the firecracker he had racked his brains to create without igniting it.In fact, it is not that there were no springs in ancient times, it was just that they were not as advanced as modern spring steel.

Li Wei picked it up and was about to try it, but Xiao Dezi who was following behind quickly stopped him.

"Sir, this thing is very dangerous, let others demonstrate it!"

Li Wei was stunned for a moment, and after thinking about it, he realized that it was the same. Ancient fire guns were at risk of exploding their barrels!

Fang Jianbao called another craftsman. As a small leader, he also cherished his life. Naturally, it was impossible for him to go up and take risks. This is how it is in this era. People are divided into three, six, and nine grades.

The craftsman finished loading the ammunition, raised the flintlock gun and pulled the trigger. It didn't fire the first time, and it took four or five consecutive shots before it did.

With a bang, a ball of fire erupted from the musket, and the projectile was shot out, nailing the target about ten meters in front.

The craftsman put down the fired gun, which was still smoking.

Li Wei stepped forward to check it out and had a rough understanding.

"Okay, I know this too. Let me think of a solution for you when I get back."

He also understood the structure of the flintlock gun. It was very simple. If he wanted to make it, he could make it now, but he had to think about it carefully, draw pictures and so on.

The three of them returned to the hut, and Fang Jianbao was served tea. It wasn't very good tea, but it was barely drinkable.

The reason why people in this era love to drink tea is not because it tastes good, but because drinking plain water directly is too unpalatable. Nowadays, wells are dug directly from the ground. They are not too deep and have not passed through. After filtration, the taste of the water depends entirely on the land, some are bitter and some are astringent. "I have read both of these things. When I get back, I will think of ways to improve them for you. Your Majesty, you don't have to worry. I think your Majesty is just trying to scare you and won't really kill you."

Li Wei took a sip of tea and said, he is really busy every day. After Lao Zhu released him from the palace, he ran outside for a day, started working immediately the next day, and then rented a house to settle down. Home, so tired!
"Sir, you must save us, we are really trying our best!"

Li Wei dared to take Zhu Yuanzhang's words as fart, but Fang Jianbao didn't dare to think so. In the hearts of little people like them, the emperor always said that he would kill whoever he said.

"Don't worry, Your Majesty, I'll go and tell you. You can just go about your business with peace of mind."

Li Weiwei comforted him comprehensively, and then said: "By the way, I still have something I want you to help me find."

"My lord, please give me instructions!"

"Well, first, pure copper, which is red or purple copper, and then find some magnets, and, by the way, raw lacquer."

Li Wei wanted these to make generators. Although pure copper with a copper content of more than 99.9% as in later generations was not smelted in ancient times, red copper has long been available. People disliked red copper for being soft and unsuitable for making utensils. Later, it was Various alloys are made by adding other metals, such as brass, bronze, cupronickel, etc.

Of course, ancient red copper is incomparable with modern pure copper, but let's just use it for now. When electricity becomes available, pure copper can be produced by electrolysis.

As for the magnets, they are ready-made. Although the magnetic field is weaker than the artificial strong magnets, it doesn't matter. Make them first, and then use electromagnetism to make the strong magnets when electricity is available.

As for the final raw paint, it is a natural insulating paint, which is also a ready-made thing. It has been widely used in this era, but it is always used on furniture.

After hearing this, Fang Jianbao thought for a while and said, "Don't worry, sir, I will help you find all the things you want."

"Ah That's good."

Li Wei majored in electrical and mechanical. When he returned to the Ming Dynasty, he felt that he couldn't do anything without electricity. Therefore, building a generator first was the top priority, and everything else had to be put in the back row!

And there is another very important reason, that is, there is a lot of useful information stored on his computer, of course not those learning materials, but serious information.

Only with electricity can computers be used, and many things will be much more convenient.

While Li Wei was chatting with Fang Jianbao, a craftsman ran in and reported:
"Master Li, Master Xue is looking for you outside the door."

Li Wei was startled, Mr. Xue, who is it?

He thought for a while, let's talk first.

"Let him in."

Not long after the craftsman went down, he brought Xue Xiang in.

Xue Xiang looked very bad at this time. When he submitted a memorial asking for money to be transferred to the shipbuilding industry, Li Wei called him back twice in a row and asked him to make a budget. He felt that this traitor was because he did not agree with him to be the minister of the Ministry of Works. Just deliberately looking for trouble!

When Li Wei saw the old man walking in, he looked familiar, and he remembered that he was the one who objected to him being the minister in the morning meeting the day before yesterday.

"Master Li!"

Xue Xiang's expression was unkind, and he held back his displeasure and bowed his hands in salute.
