Daming pirates

In fact, rifled guns are not too high-tech. Rifled guns appeared very early in history. In the 15th century, the Germans made linear rifled guns. In the 16th century, someone also made another.

The spiral rifling can make the projectile rotate when it exits the chamber, improving shooting accuracy.

However, due to the difficulty in manufacturing rifling, no one has invented a suitable rifling machine tool that can be mass-produced. In addition, no one has yet been able to solve the problem of difficulty in loading rifled guns. Therefore, although someone has already tried to produce a rifled gun.

However, it has never been popularized, let alone recognized by various [***] teams.

As for the problem of projectile loading, the first one is that people are still using round projectiles. Even if such projectiles are given the ability to rotate, the improvement in accuracy and power is not very obvious. In addition, musketeers who use rifled guns are loading

When using projectiles, because the projectiles are slightly larger than the diameter of the bore, they must be jammed

It enters the rifling, and it is very difficult to load. Sometimes you even have to hit the purge with a hammer to insert the projectile into the barrel.

The gunman is very embarrassed, so although the rifled gun has various advantages, it has never been loved by users.

Moreover, the production cost of a rifled gun is much higher than that of an ordinary smoothbore gun, and it is not easy to manufacture. Therefore, before the invention of the minie bullet, this rifled gun was never recognized by all parties and could not replace the smoothbore gun.

Therefore, in fact, the manufacturing of rifling is not a very difficult matter. Western craftsmen have solved this problem earlier than this era. So for Xiaotian, it is not too difficult to do. He can learn from the history of handicrafts.

The way to make rifling is to make a rifled gun.

For this reason, Yu Xiaotian had read some information about how old craftsmen made rifling and some simple mechanical tools from various channels a long time ago. This matter was not difficult for him.

But there is a reason why he waited for so long before taking this thing out. To make a rifled gun, you must first have the foundation of making a smoothbore gun, and the process requirements are relatively high. If you don't even have an ordinary smoothbore gun,

If you can't do it, then if you want to produce rifled guns, you will naturally be looking at the moon in the water, and it will be elusive.

Therefore, he previously focused his energy on the production of muskets. He fired the golden finger first and made a relatively advanced flintlock gun of this era. He first took advantage of it and allowed his subordinates to practice their gun skills.

A group of craftsmen who were good at making muskets emerged.

But now it seems that after such a long time of making muskets, Seawolf Gunsmith has accumulated quite a wealth of experience, the product quality has begun to stabilize, and the craftsmen's proficiency has also met the requirements. What's even more rare is that they have "

We have developed a lot of special jigs and molds for making guns, and even developed several simple machines for making guns, which gives us a better foundation for making rifled guns.

Yu Xiaotian has read several time-travel novels before. As soon as the pig's feet in them appeared, they started to explode weapons. At the very least, they directly exploded Migne rifles. Some even exploded all kinds of modern weapons.

Even in the coming year, ak will be no problem, sweeping the world with invincible opponents!

Yu Xiaotian can be said to sneer at this point. It is simply nonsense. Even if it is not difficult to make a rifled gun, at the very least, you must first have the foundation to make an ordinary smoothbore rifle. If you want to make a rifled gun directly, even

To create modern weapons, it is said that the problem of materials and technology cannot be solved. Even if it can be solved, it still involves a chemical industry, which is pure deception.

That's why he took his time step by step and gradually improved the basics. Only then did he bring the matter of trial production of rifled guns to the table.

In fact, the old-fashioned rifled gun is just a smoothbore gun with rifling carved into the barrel. The rest of it is not much different from the smoothbore gun. It is just a development product of the old-fashioned smoothbore gun.

Yu Xiaotian never thought about eating a fat man in one bite and directly building a modern rifling machine. The sketch he drew this time was an old-fashioned rifling machine with a structure that was invented by gunsmiths a long time ago.

It is very simple, does not require high technology or strong driving force, and can be produced entirely by manpower.

In some time-travel novels, when Pig's Foot is making a Miner rifle, what does the rifling mean? First, the rifling is carved diagonally on the iron plate, and then the iron plate is rolled up, just to match the rifling interface, forming a rifled gun.

No matter, it seems to make sense in theory at first glance.

But when it comes to actual work, this method is simply nonsense. No matter how brilliant the craftsman is, even if he finds the best blacksmith in the world and asks him to use this method, he will not be able to do it in a high-tech industry without modern iron plate rolling.

With the help of precision machinery, it is impossible to roll up the rifled iron plates and fit the interfaces together exactly. What's more, at this time, the barrel is made, which requires the use of a hammer.

The welding method is to hammer weld the joints of the iron pipes together. Even if the rifling is engraved inside, they can be butted together. The rifling will still be flattened during hammer welding, and it will still come out as a smooth smoothbore barrel.

.

Therefore, if you want to obtain rifling, you can only make a qualified smoothbore barrel first, and then find a way to carve rifling inside. Only then can you make the barrel of a rifled gun.

Yu Xiaotian didn't give Zhang Tiejiang too many introductions or explanations, so he let Zhang Tiejiang lie on the table and look at the sketch he drew. He found a chair to sit down and drank, and the servants brought it to him.

of tea.

Zhang Tiejiang studied the sketch carefully, and gradually understood the machine drawn on the sketch, and found the key to it. He straightened up and said to Xiaotian with admiration on his face: "Master.

, I have already figured it out! This thing is not too difficult, I should be able to figure it out!

If I'm not mistaken, the key to this thing is probably on this threaded roller. When you pull this thing, you can just take the drill bit and rotate it inside the blunderbuss tube. When you pull it out or push it in, it just happens to be inside the blunderbuss tube.

A groove is carved into the bore, which is what the boss calls rifling! Pull out one thread at a time and reciprocate a few times, and you can pull out the rifling!"

Yu Xiaotian put down his tea bowl, clapped his hands with a smile on his face, stood up and laughed loudly: "Old Zhang! I'm convinced by you, and I saw the key after just looking at this sketch!

You are right, the key is on this roller, the spiral groove on it is stuck here, and this rod is not a drill bit, it should be called a hook knife. The front one is made with a drill bit that is similar to or even harder than the ones you make.

Some hook blade heads made of fine steel can be two facing each other or one. First penetrate into the gun tube, install the hook blade on this end, and then pull the roller from this side. The roller is in

When these grooves are pulled out, they will rotate, driving the hook knife into the musket chamber. They will rotate as they go. When the hook knife is pulled out from this end, rifling will be carved inside.

Of course, you can't pull out the rifling at one time. You have to pull it several times. The specific number of times depends on the level of your hook knife. After pulling out one or two riflings, adjust the hook knife and you can continue.

Pull out other riflings. Don’t have too many riflings now. It’s enough to start with four riflings. After all the riflings are drawn out, other things can be done according to the old method. Once installed, it will be a rifled gun.

You will know how powerful this guy is when you try it!

By the way, I forgot to tell you, this roller with spiral grooves does not need to be made of iron. It can be used directly by a carpenter making it from hardwood. Otherwise, it would be too heavy and it would be very laborious to pull it! This is very important to the carpenter.

It is said that any carpenter with similar skills can do it, so it is not too difficult at all!

Do you understand? Take advantage of what you don’t understand at the moment and ask quickly. After you understand it thoroughly, you can quickly make it. I am eager to use this good thing!

Although our previous flintlock guns were good, their range was a bit too close, and they were not as far as the Ming Army's muskets. If they were to attack the Ming Army's musketeers, our brothers would probably suffer a lot of casualties!

But with this guy, no matter who it is, if they encounter us, they will only be killed! Even if the matchlocks of the Taishi encounter our musketeers, they are looking for death!"

Blacksmith Zhang still doesn't quite understand that just carving a few spiral-shaped grooves in the barrel of the gun can make the gun hit farther and more accurately. But since Yu Xiaotian is so confident and swears by it, then he

He has blind worship for Xiaotian now, and firmly believes that Yu Xiaotian's words are definitely correct, so regardless of whether this thing is easy to use or not, he must make it quickly even if he uses all his strength.

Otherwise, he would have failed Yu Xiaotian's trust and expectations in him.

So he quickly agreed and began to look at the pictures carefully again, and then pointed out to Yu Xiaotian some of the things that he didn't quite understand, and Yu Xiaotian explained them to him in detail.

In fact, Yu Xiaotian has never made such a thing. The later dynasties banned guns very strictly. Even if he was an avid firearms enthusiast, he would not dare to make such a thing easily. He secretly made a fire dog with a steel pipe, which was enough.

He didn't dare to show off easily, so he was just a theoretical giant with theoretical knowledge and standards, but a dwarf in action.

If he is allowed to make this kind of rifling machine by himself, even if he is given a few years, he may not be able to make something qualified. Therefore, this kind of thing must be left to professionals, and Blacksmith Zhang is undoubtedly the most suitable one.

chosen.

The two people gathered around the table and discussed for two hours. It was not until dark that Fang An came over to invite Yu Xiaotian to go back to the city for dinner. The two of them ended the discussion. Blacksmith Zhang had already finished the rifling machine.

The basic structure and principles are roughly and thoroughly understood.

Originally, Yu Xiaotian wanted to ask Blacksmith Zhang and others to have dinner together, but Blacksmith Zhang was not in the mood to have a meal at the moment. He was in a hurry to go back and start tinkering with the machine all night long, even if he had some free time.

He quickly looked at the note that Yu Xiaotian gave him, and flatly rejected Yu Xiaotian's invitation.

If it had been anyone else, Yu Xiaotian would have been annoyed a long time ago, but if it had been Zhang Blacksmith, that was another story, so he laughed and left Blacksmith Zhang to work overtime overnight, and followed Fang An back to the city.

(I’ve been having a bad time these days! My anus hurts, and my monthly ticket has been exploding for several days!)
