Daming pirates

At this time, Yu Xiaotian asked Blacksmith Zhang and others to come over and try their hand at it, so that they could personally feel the power of the weapon they had made with their own hands.

So Blacksmith Zhang and the several craftsmen he brought along also tried firing a few rounds each, and everyone was surprised, excited, and quite proud.

Because this kind of killing weapon was made by their hands, but even they themselves couldn't believe it. Just by carving so many rotating grooves in the barrel, the power of this kind of musket became

It's so big, it's really surprising.

When everyone was test-firing, someone was assigned to record the number of firings for each gun. When the first gun used by Liu Wang fired twenty times, Yu Xiaotian stopped and refused to allow anyone to use this gun again.

.

He ordered the gun to be sent over, personally inspected the barrel and observed the condition of the bore. He also used a small plate to disassemble the gun, unscrewed the screws at the end of the barrel, and clamped the oilcloth with a straight strip.

Tiao wiped the barrel of the gun and brought the barrel to his eyes for a closer look.

After twenty rounds of firing, the inner bore of the barrel seemed to have changed little, but it felt like the rifling was not as deep as it was initially.

So Yu Xiaotian ordered Blacksmith Zhang to take out the caliper he had brought with him and check the inner bore of the gun barrel.

After inspection, it was found that the diameter of the barrel's inner bore has been enlarged, and the rifling in the inner bore has also begun to become shallower.

In fact, this situation is normal. After continuous shooting, the barrel of the gun has to continuously withstand the huge chamber pressure when the gunpowder deflagrates, which will cause the barrel to expand outward. In addition, the bullets are closely attached to the barrel in the barrel.

It also accelerates the wear of the barrel.

This shows that when this type of gun is fired, the inner bore of the barrel wears out very quickly, and the effective life of the barrel may be quite low. Judging from the current situation, the effective service life of the barrel of this rifled gun is probably

At most, it can be within a hundred rounds. After about a hundred rounds, the rifling in the barrel will be almost gone. By then, even if the barrel of this gun is still usable, it is estimated that

It will also become a musket again.

Relatively speaking, this situation is much better for smoothbore guns. The chamber pressure of smoothbore guns is not as high as that of rifled guns. There is a certain gap between the projectile and the inner wall of the barrel, which will cause deflation and reduce some of the bore pressure. In addition, the projectile also interacts with the gun.

The friction of the tube is much smaller, and the rifling makes the barrel wall thinner. Therefore, when the barrel of the smoothbore gun is made of wrought iron, it has an effective service life of several hundred rounds, even as long as the barrel wall does not crack or be severely deformed.

, it can be used continuously without causing much impact.

But this is not the case with rifled guns. Rifled guns have high requirements for materials. This is not only a problem of high chamber pressure. The key is that the inner bore of the rifled gun must have a higher hardness to withstand the wear and tear of the bullet in the chamber.

The wrought iron they currently use to make gun barrels, even the best refined iron, is not good. After all, the hardness of wrought iron is too low. Even if it is replaced with low carbon steel, it will be much stronger than the current wrought iron.

It's a pity that he doesn't have the ability to make steel at the moment, so he can only use wrought iron to continue to make gun barrels for the time being. So after all, the production of steel is now imminent. This has become a bottleneck restricting the continued development of Sea Wolf. It must be

We have to find a way to break through this bottleneck.

Yu Xiaotian couldn't help but write down another note in his notebook, steel! Steel! Still steel!

Next, he asked people to continue testing with this gun. When the gun reached thirty rounds, its accuracy began to decrease and the rifling wear became more serious.

Originally, he wanted to continue the experiment, but unfortunately, the first batch of mine bombs he trial-produced had been used up by this time, so he could only give up and took the people back to Tamsui City while ordering the weapons.

The projectile factory under its jurisdiction has stepped up its efforts to produce a batch of Minie bullets for test use, and is preparing to open molds to manufacture molds specifically for casting Minie bullets. The next step is to mass-produce Minie bullets and begin supplying rifled guns to the army.

use.

It was only then that he told Fang An, Meng Fei and others about the principles and specifics of the rifled gun.

This group of people listened a little confused. They didn't understand some of the professional terms used by Yu Xiaotian at all. However, after testing the new gun today, they knew very well that the rifled gun Yu Xiaotian had newly tinkered with was really good.

It is a very sharp weapon, far behind many similar firearms of this era.

Once they are equipped with such rifled guns in large quantities, the firepower advantage of the Sea Wolf will be completely established in the future. No matter who they fight in the future, the Sea Wolf will basically be invincible.

Of course, this also requires certain prerequisites, that is, the number of Sea Wolf's troops can be inferior to the opponent's military strength, but this gap in military strength cannot be too wide, otherwise the enemy can still rely on numbers.

Advantage, rely on the human sea tactic to drown the Sea Wolf tribe alive. Once the opponent breaks through their defense line and enters a close combat, whoever has more people will have the last laugh.

Yu Xiaotian announced in public that this time, Blacksmith Zhang and several blacksmiths and apprentices who cooperated with Blacksmith Zhang in making the rifling machine would be credited and rewarded, and he ordered them to continue to work on this new machine.

Improve the rifling machine to make it faster to use, produce products with higher precision, and finalize the shape as soon as possible to produce a batch of such rifling machines and put them into gun production to produce new rifled guns.

As for this rifled gun, Yu Xiaotian thought for a while and named it the Langya Type 2 flintlock rifled rifle, or Langya rifle for short, to show that this brand-new rifled rifle will become a sharp tooth of the sea wolf.

The bullets produced are also called wolf teeth.

As for the Migne rifle, Mr. Migne still has nearly two hundred years to be born, so don’t mention it. Now he has plagiarized Mr. Migne’s invention and let Mr. Migne, who will be born two hundred years later, make another

Find a way to live a happy life!

The successful development of the Wolf Fang rifle has enabled Sea Wolf to finally possess a modern weapon that far surpasses this era. Regardless of the muskets or cannons they produced in the past, although they are somewhat ahead of this era, the technical level does not exceed it.

Many, only the iron cannon casting method can be regarded as a technology that has surpassed this era. Other than that, other things, compared with the weapons of the same era, are not technologically superior by much.

The flintlock gun is considered a type, but the French in Europe have also developed the same type of flintlock gun during this era. However, due to various reasons, it has not been promoted and used for the time being, which makes the sea wolf occupy a little bit of this kind of firearm.

Cheap. In fact, the flintlock gun had been invented in Europe a long time ago. The kind of flintlock gun that Yu Xiaotian tinkered with did not surpass the technology of the times.

However, this kind of Wolf Fang Rifle (Mine Rifle) has truly surpassed the level of similar weapons of this era. Even if someone has already trial-produced a rifled gun, they have not mastered the mature manufacturing technology and have not invented it.

Minie bullets were produced, so even in the West, few people knew about this rifled gun. As for its promotion, it was more than two hundred years later, in the mid-19th century.

If Seawolves mass-produce such weapons in the future and equip the troops for use, then they will be two hundred years ahead of the times in terms of infantry weapons, and can use nineteenth-century technology to deal with seventeenth-century enemies.

He has completely stood at the highest point of technological superiority. Although he dare not say that he is invincible now, at least in the face of enemies several times his own, the Sea Wolf tribe will basically not suffer any loss.

An alcohol distillation workshop was established outside Danshui Village. By the Ming Dynasty, the technology of distilling liquor to obtain high-alcohol liquor had matured. There were already many kinds of local shochu, so preparing alcohol with higher purity was no longer a problem.

There are technical difficulties.

However, the alcohol distillation technology in this era is not very standardized, the efficiency is not very high, the speed is slow, and the waste is relatively large. In this newly built wine making workshop, Yu Xiaotian put forward some suggestions for improvement in the distillation process. One is to strengthen the still pot.

In addition, the pipe part is made of glass, a spiral glass jar is used as a condenser, and cold water is introduced from the outside of the pipe in the condensation part to increase the condensation efficiency.

As for the rest, we continue to use the old method, using ceramics or iron sheets to make them. It is not difficult. The biggest difficulty is the glass condensation pipe.

Now, after such a long period of production at Seawolf's glass factory, the glass craftsmen inside have been repeatedly testing the glass blowing technology in the past two years. Now they are quite good at it. The glass tube itself is not difficult.

It takes no effort to blow something, and after blowing it into a glass tube, the glass tube is heated again and twisted into a twist shape, and it is ready.

Therefore, when the glass tube condensation device was transported to the wine making workshop, it caused a cry of exclamation. In this era, glass is an absolute luxury product in the eyes of everyone, and Yu Xiaotian's such a big move, even distilled wine

Having used so much glassware, not to mention how much the wine is worth, at least this set of glassware for distillation is worth my money!

After only a small improvement in this way, the efficiency of this set of tools for distilling alcohol has been reflected. Compared with the original old-fashioned distillation process, the efficiency has been improved a lot. After adding materials and igniting, the wine is quickly discharged from the pipe.

Clear wine trickled out of his mouth.

The entire winery was filled with a strong aroma of wine, so some people couldn't help but take a little bit of the wine and taste it. The alcohol content was very high, and those who tasted it were so spicy that they grinned and became addicted.

It's a pity that Yu Xiaotian can't get an alcohol meter and can't measure the alcohol content. He asked the glass factory to find a way to trial-produce a thermometer. Now he only has to wait for pure alcohol to be produced before the thermometer can be made, so he can't measure it.

Before the purity of the alcohol is determined, the only way to do it is to distill the wine twice more, so that you can basically get alcohol with a very high purity.

Whether the Sea Wolf is in Nanyue Island or Tamsui Chicken Coop, they need to save food and meet unexpected needs at any time. Food is a material under their control, and they are not allowed to make wine in normal times.

But now, sugar cane has begun to be planted in Tamsui, and sugar cane houses have been built, producing a lot of bagasse. Bagasse is a good raw material for wine making, so Yu Xiaotian decided to open a winery to make wine.
