Chapter 53 Simple Rout Machine

In fact, the rifle is not a very high-tech thing. A rifle has appeared very early in history. In the 15th century, Germans made straight rifles. In the 16th century, some people made spiral-shaped rifles, which can give bullets rotation and improve shooting accuracy.

However, due to the difficulty of manufacturing the riverb, no one has invented a machine tool that can be used to mass-produce the ripped wire. In addition, there is no one who can solve the problem of loading the river gun for the time being, so although the river gun has been tried out for a long time, it has not been popularized, let alone the armies of various countries. The recognition.

As for the problem of projectile loading, the first is that people are still using round projectiles. Even if such projectiles are given rotation ability, it is not very obvious for the improvement of accuracy and power. In addition, the * hand that uses the bore gun, when loading the projectile, because the projectile is slightly larger than the inner bore diameter, it must It is very difficult to get stuck in the bore line and fill it. Sometimes it is even necessary to knock through the bar with a hammer to stuff the projectile into the barrel. It is clumsy and powerful, and sometimes the * hand is very embarrassed because the projectile cannot be stuffed into the gun. Therefore, although the bore gun has various advantages, it is never appreciated by users. Love.

Moreover, the production cost of the bore gun is much higher than that of ordinary smooth bore guns, and it is not easy to make. Therefore, this kind of bore gun has never been recognized by all parties before the invention of the Mine bullet, and it has never been able to replace the bore gun.

So in fact, the manufacture of ripped wire is not a very difficult thing. Western craftsmen earlier than this era solved this problem, so it is naturally not too difficult for Xiaotian. He can completely learn from the hand-made rivering method in history to make a rifle.

For this reason, Yu Xiaotian had seen some methods and some simple mechanical tools about how old craftsmen made worms from various sources a long time ago, which was not difficult for him.

But there is a reason why he waited so long to take this thing out. To make a rifle, you must first have the foundation for making a smoothbore rifle, and the process requirements are high. If he can't even get an ordinary smoothbore gun, then if you want to make a rifle in the production line, you must also look at the moon in the water. It can't be expected.

So he used to focus on the production and production of smoothbbaguns. He first opened his golden finger and made a relatively advanced huskling gun in this era. He first occupied some advantages and trained a group of craftsmen who are good at making smoothbba guns among his guns.

Now it seems that after such a long time of building smoothblin guns, Sea Wolf's gun has accumulated considerable experience, the product quality has begun to stabilize, and the proficiency of craftsmen has also reached the requirements. What's more rare is that they have "developed" many fixtures and molds for gun manufacturing, and even made Several simple machines for making guns make a better foundation for making rifles.

Yu Xiaotian has also read several time-travel novels before. As soon as the pig's feet appeared, they began to explode weapons. At the very least, they directly exploded the Minee rifle. Some simply burst out all kinds of modern weapons, and even AK will be invincible in the coming year, sweeping the world!

Yu Xiaotian can be sneered at this point, which is nonsense. Even if it is not difficult to build a rifle, at least you must first have a foundation that can make ordinary smoothbore rifles. You can directly build a rifle, and even make modern weapons. Even if the problems of materials and technology can be solved, it also involves a set of chemical industry, which is simply a fool.

So that's why he took it step by step and gradually improved the foundation. It was not until this time that he brought the trial production of the rifle to the table.

In fact, the old-fashioned rifle is to carve a rebarred line in the barrel of the smoothb gun. The rest of the place is not much different from the smoothb gun. It is just a development product of the old-fashioned smooth-fire gun.

Yu Xiaotian has never thought of eating a fat man and directly creating a modern machine for pulling worms. The sketch he drew this time is an old-fashioned worm machine invented by gun craftsmen a long time ago. The structure is very simple, without too high technology or too strong driving force. Manpower can be produced.

In some time-travel novels, when the pig's foot made the Mine rifle, the opening line said that the rifled line was first depicted diagonally on the iron plate, and then rolled up the iron plate to match the rifle interface to form a barrel with a rifled wire. Theoretically, it seems to be a little reasonable.

But in practice, this method is simply nonsense. Any smartest craftsman, even if he finds the best blacksmith in the world, let him use this method. Without the help of the high-precision machinery of modern iron plates, he wants to roll up the iron plate with good riop. So that the interfaces can fit together, there is no possibility at all. What's more, at this time, the barrel is built. It is necessary to use the method of hammer welding to hammer the seam position of the iron pipe together. Even if the bridle is carved inside, it can be docked up. When the hammer is welded, the worm wire is still flattened, and it is still a bare. Slippery barrel.

So if you want to get the rifled wire, you can only build a qualified smooth-fire barrel first, and then find a way to carve the rifled wire inside, so that you can make the barrel of the wire rifled gun.

Yu Xiaotian did not give too much introduction and explanation to Zhang Blacksmith, so he let Zhang Blacksmith lie on the table and watch the sketch he drew. He found a chair and sat down and drank the tea sent by his servants.

Zhang Blacksmith carefully studied this sketch, gradually understood the machine drawn on this sketch, and found the key. He straightened his waist and said to Xiaotian with admiration, "Big master, the little one has seen it! This thing is not too difficult. The small one should be able to get it out!

If I'm not mistaken, I'm afraid the key is that this guy is on this threaded roller and pulls this thing. It's just right to take this drill to turn around in the pipe. When it is pulled out or pushed forward, he will carve a groove in the chamber of the pipe. This is what the big boss said! Every time you pull out a thread, you can pull out the wire several times!"

Yu Xiaotian put down the tea bowl, applauded with a smile on his face, got up and laughed, "Lao Zhang! I'm finally convinced by you. I only looked at this sketch and saw the key!

You are right. The key is on this roller. The spiral groove on it is just stuck here, and this rod is not a drill bit. It should be called a hook knife. The front is a hook knife head made of fine steel similar to or even harder than the drill bit you made. It can be The two opposite can also be one. First, go into the pipe, put the hook knife on this end, and then pull the roller from this side. When the roller is pulled out of these grooves, it will rotate, driving the hook knife into the sling chamber and rotate as you walk. When the hook knife is pulled out from this end, the chamber line will be carved out.

Of course, you can't pull the rivets at a time. You have to pull it several times. How many times it is appropriate depends on the level of your hook knife. After pulling out this or two rivets, adjust the hook knives, and you can continue to pull out other rivets. Now don't have too many rivets. Just start with four. That's enough. After all the river is pulled out, other things will be done according to the old method. When it is installed, it will be a worm gun. When you try it, you will know how powerful this guy is!

By the way, I forgot to tell you that this roller with spiral groove is not made of iron. It can be used directly by carpenters to make it from hardwood. Otherwise, it will be too heavy, and it will be difficult for manpower to pull! For carpenters, carpenters with similar skills can do it, which is really not too difficult!

Do you understand? Ask what you can't understand at this moment. After thoroughly figuring it out, you can do it quickly. I'm eager to use this kind of good guy!

Although our previous framing gun is not bad, the range is a little too close. It is not as far as the Ming army's bird gun. In case a pair of Ming army * hands, I'm afraid our brothers will have a lot of casualties!

But with this guy, no matter who meets us, he will only be slaughtered! Even if the Tesi people's arquebus hits our soldiers' hands, they are still looking for death!"

Zhang Blacksmith still doesn't understand very well, but carving so many spiral-shaped grooves in the chamber can make the fire more accurate. However, since Yu Xiaotian is so confident and vowed to guarantee, he now has a blind worship of Xiaotian and firmly believes that Yu Xiaotian's words will definitely not have Wrong, so no matter whether this thing is easy to use or not, even if he uses his strength to breastfeed, he must make it quickly, otherwise he will fail to live up to Yu Xiaotian's trust and expectation of him.

So he quickly agreed, began to look at the picture carefully, and then mentioned to Yu Xiaotian some parts that he didn't quite understand, so Yu Xiaotian explained it to him carefully.

Yu Xiaotian has never done such a thing. In later dynasties, the ban on guns is very strict. Even if he is a fanatical firearms enthusiast, he does not dare to do this kind of thing easily, secretly make a steel pipe *, and does not dares to easily show off, so he is just a theory with theoretical knowledge and standards. On giants, action dwarfs.

If he is allowed to make this kind of wire pulling machine by himself, even if he is given a few years, he may not be able to get qualified things, so this kind of thing still needs to be done by professionals. Zhang Blacksmith is undoubtedly the most suitable person.

The two people gathered around the table and discussed for two hours. It was not until dark that Fang An came to invite Yu Xiaotian back to the city for dinner. The two ended the discussion. Zhang Blacksmith had thoroughly understand the basic structure and principle of the lapping machine.

Originally, Yu Xiaotian wanted Zhang Blacksmith and others to have dinner together, but Zhang Blacksmith was not in the mood to eat at this time. He was in a hurry to go back and began to play with the machine overnight. When he was a little free, he had to read the note given to him by Yu Xiaotian, so he flatly refused Yu Xiaotian's invitation.

If this was someone else's words, Yu Xiaotian would have been annoyed, but if it was Zhang's blacksmith, he would have said something else, so he laughed and left Zhang blacksmith to work overtime overnight and followed Fang An back to the city.

(I'm not happy these days! ** It hurts, the monthly ticket has been spent for several days in a row!)
