Daming pirates

He opened the notebook and started flipping through it one by one. The more he looked at it, the bigger his eyes became. The more he looked at it, the more surprised he became. Even his hands started shaking as he looked at it. Suddenly he closed the notebook and held it with both hands.

With a plop on his head, he knelt down in front of Yu Xiaotian and said to Xiaotian with a trembling voice: "Master! Thank you very much for giving me such a treasure! Master, you are a god! Please accept my respects!"

Yu Xiaotian accepted his worship, thinking that he knew the importance of this notebook to a person who is passionate about mechanics. If ordinary people don't understand mechanics, they may regard this notebook as waste paper and wipe their butts.

It's not soft enough, but if it were Blacksmith Zhang, he would definitely understand the importance of this notebook.

So for Zhang Tiejiang, this book is a treasure, a treasure more important than anything else, and this notebook is very likely to open the door to an industrial era, or at least it can be called a key.

It also contained his countless days and nights of hard work. Now that he handed it over to Blacksmith Zhang and received his respect, it was only natural that he should do so.

After Blacksmith Zhang kowtowed, Yu Xiaotian stretched out his hand to lift him up and said to him: "For the time being, you are still working in the gunsmithing industry. The title I gave you is the technical director of gunsmithing, and you are only responsible for the craftsmen."

As for our craftsmanship and technical matters, we can’t let you get rid of them all yet!

You must keep this book properly, because I only have this one, and I don’t have another one! And you should read this book by yourself first. If you don’t understand, you can ask me when you see me later. I will go with you.

Think about it! You must thoroughly understand it, and then gradually pass it on to the apprentices, but you cannot show it to others easily, let alone let it flow outside! This is related to the future of our sea wolves in the future, you must remember it!"

Zhang Tiejiang was so excited that his face turned red. He nodded and pointed to the sky and swore: "Master, please rest assured, I have written it down! This book is more important than my life. Even if I die, I can't let it go."

Lost or destroyed! The little one will read this book carefully and then copy it. After the little one has finished the copying, the little one will

Immediately return it to the big boss! Thank you to the big boss for trusting the little one. The little one doesn’t know how to repay the big boss in this life! As long as the little one is still breathing, this life belongs to the big boss! Wherever the big boss goes in this life

, the little one will follow you wherever you go! If you regret it, the little one will die badly, and everything will not be reincarnated!"

Yu Xiaotian nodded and said: "Okay! I trust you, so I will give this to you. You can copy it and learn more about it!"

In addition, you can choose a few apprentices who like to do this business. They may not be very smart, but they must like to do this from the bottom of their hearts. Take them as your apprentices and pass on what you have learned to them. I don’t want them.

Everyone becomes a master craftsman and can beat iron

They are very good. In that case, they are just rough craftsmen at best. I want them to learn to think more in the future and be able to create new things. They don’t need to do it themselves. As long as they can draw what they want, it is enough. As for making things naturally,

Just let others do it for you!

When I have time, I will teach you mechanical drawing, and I will also get some drawing tools! Okay, that’s it!”

Zhang Tiejiang was so excited that he followed Yu Xiaotian. At this moment, he almost regarded Yu Xiaotian as a god. He wanted to eat that notebook quickly to feel at ease.

Yu Xiaotian took a look at the gun production situation here and was quite satisfied with the production here. At least it no longer looked like a workshop-style blacksmith shop, but had a serious factory feel.

It felt so good, even if it was extremely hot in here, he would still be willing to stay in this place for a while.

Yu Xiaotian personally inspected several produced flintlock guns. The focus was on the workmanship of the flintlock mechanism, the manufacturing accuracy and quality, and the condition of the barrels.

After such a long period of exploration and training, gun craftsmen have become quite sophisticated in crafting such barrels. Although the material is wrought iron, which is far from comparable to the alloy steel of later generations, even in Europe in this era

People are also using such materials to make gun barrels, but their lifespan is relatively shorter.

In terms of craftsmanship quality, the quality of the gun barrels currently manufactured by Sea Wolf is comparable to the quality of gun barrels produced by craftsmen from any country in the world at this time. In this way, he has been considering another weapon.

, and the conditions for production are initially met.

Yu Xiaotian took Blacksmith Zhang to a quiet place in Qianzuo, stood in front of a table, and said to Blacksmith Zhang, "Old Zhang, do you still remember the thing I mentioned to you before?"

Zhang Tiejiang was a little dizzy with excitement at the moment. He didn't think of anything Yu Xiaotian had mentioned to him before, so he scratched his head and said, "At the moment, I'm just busy being happy and can't think of anything."

What is the matter that the master is referring to! Please make it clear, master!"

Yu Xiaotian sweated, smiled and asked Blacksmith Zhang to put down the notebook first and talk quietly. After taking a sip of water, he said to him: "That's the gun I brought to you when I came here.

He can kill people from a hundred steps away, and he can even shoot farther, and his shots are incredibly accurate!"

When Zhang Tiejiang heard this, he patted his head and said: "So that's what happened! The big boss has caused trouble to the little one. Ever since the big boss mentioned this matter, the little kid couldn't let it go for many days. It's really

It’s really heartbreaking, I’ve been thinking about this all the time!

The younger one really couldn't think of any way to hit a musket so far, and to take someone's life from a distance of 200 steps as easily as picking something out of a bag! Later, he was really too busy, so the younger one gradually took care of this matter.

Let it go!

Do you want the big boss to tell the little one today how this thing is made? Please don’t hold back anymore! Tell the little one quickly! The little one will have free time in the future. As long as the big boss tells him, the little one will

We must do it quickly!”

Yu Xiaotian nodded and said: "Yes, after seeing your craftsmanship today, I think I can leave this matter to you!

In fact, the thing I'm talking about is not much different from the current flintlock gun! It's just a matter of carving a few lines on the wall of the barrel! I call it a rifled gun..."

As Yu Xiaotian spoke, he spread out a piece of paper and roughly explained the rifling to Blacksmith Zhang with a charcoal pen.

"Is it difficult to carve grooves in the barrel of a gun? The barrel is so thick, so how can you carve it? It won't fit in! If you carve a straight line, it would be easier. For small ones, you can get a knife.

Even if you force it in and pull it out a few times, you can get it out!

But if the boss wants to carve grooves on the inner wall of the gun chamber, he also needs to make the grooves rotate. This is probably really difficult! The younger ones have to think about it and think of a way!

But after carving such a few lines into the barrel of the gun, can the gun be made to hit far and accurately? What is the reason for this? "

"This is actually not complicated. Let's first talk about why after rifling is carved, the gun can hit farther and more accurately!..." So Yu Xiaotian began to explain the role of rifling and the advantages of rifled guns to Blacksmith Zhang in detail.

, it took him a while to finally understand the benefits of doing so.

"That's it! I really can't believe how the master came up with these things. If there are so many benefits, then it would be really amazing!

By the way, if we do this, I’m afraid this gun will be difficult to handle! If it’s too big, I’m afraid it won’t fit into the barrel. If it’s small, there will be a few grooves on the barrel of the gun.

Will you still be discouraged? It won't work!" After hearing this, Blacksmith Zhang finally understood the problem with the rifled gun, but he was now able to think, and he immediately thought of the problems involved.

Yu Xiaotian immediately thought of this problem when he heard about Zhang Tiejiang. He was really surprised by Zhang Tiejiang's reaction speed and couldn't help but look at him with admiration.

"Okay! It's great that you can think of this! But this matter is another matter to talk about. Don't worry about it for now. The blunderbuss of rifled guns is not the same as the blunderbuss of straight-barreled smoothbore guns like the one we make now.

The guns are different. Now we use round blunderbuss, which are used for rifled guns.

It will be long, and the weight will be much heavier than the current musket musket! It has a large mass and a high muzzle velocity, so it will naturally hit far. In addition, it will rotate when flying, so it will naturally fly steadily. This

After you get the rifling done, I'll tell you how to do it.

As for the rifling issue, I have already thought about it, please come and bring me the drawings I drew during the Chinese New Year!" Yu Xiaotian said.

Liu Wang immediately took out a roll of paper from a whale skin waterproof round leather bucket he was carrying, sent it to Yu Xiaotian, spread it out on the table, found a few wooden blocks as paperweights, and pressed it down

drawing.

A sketch of a machine similar to a drilling machine appeared on the paper and appeared in front of Blacksmith Zhang.

Blacksmith Zhang immediately lay down on the table, like a dog that had been hungry for several days and suddenly saw a bone, and greedily began to study the sketch.

For an old craftsman like Zhang Tiejiang who already has a certain amount of experience, Yu Xiaotian no longer has to explain too much to him, and there is no need to draw a three-sided diagram with clear dimensions. These details are

Zhang Tiejiang will naturally improve things by himself. He only needs to give him a general idea, which saves Yu Xiaotian a lot of effort.

As a military fan, especially someone who likes weapons, many people are very curious about how guns are made, especially how things like rifling can be made, so Yu Xiaotian is no exception.

, in the past time and space, he would often search for some videos or information about this in his spare time.

Therefore, he still has a certain understanding of how to make rifling. Of course, although he knows the method of making rifling by modern machines in later generations, he does not have the conditions to make it. He can only use more primitive means and techniques to make this kind of rifling.
