Becoming stronger from cutting Hu and Cao Cao

Chapter 525 A product of a cross era.

The most difficult part of making a barrel is how to drill the rifling.If the barrel is made of pure iron, the iron is too hard to drill rifling in it.

However, if the barrel is made of pure copper, it is easy to drill out the rifling.However, if the copper is too soft, when the bullet and the rifling heat up due to friction, the rifling will deform after many shots, causing the chamber to explode.

One is because it is too hard to use, and the other is because it is too soft to be hard. It can be seen that the best thing is neither soft nor hard.
It was under such circumstances that after two years of experiments, Huang Yueying finally found the most suitable copper-iron alloy formula for making gun barrels.

"King Qin, you are here!"

"Are you going to see my gun?" At this time, Huang Yueying came out of the office next to the factory building with a thick stack of documents.

Li Chen said in his heart, I don't just want to see your gun.

Of course, although I thought so in my heart, I definitely couldn't say that.

After all, the majestic king of Qin, in public, still can't play hooligans.

"Well, come and have a look!" Li Chen replied softly.

After about half an hour, this piece of copper-iron alloy has been fused into one after repeated forging.In the hands of craftsmen, it was beaten into a cylindrical alloy rod.

It has to be said that the craftsmen of this era are really powerful, just beating with their hands without any equipment, extremely, they can make such rules.

After this step is completed, the next step is to polish the alloy stick, so that he has the appearance of a gun barrel completely.

"Miss Yueying, are you on the rig?" An old craftsman asked Huang Yueying.

Although Huang Yueying was young and a girl, the old craftsmen in the arsenal admired Huang Yueying from the bottom of their hearts.

Almost all the equipment for making flintlock guns were designed by Huang Yueying herself.It is precisely because of these advanced equipment that craftsmen can create various parts of firearms.

During these three to five years, Huang Yueying began to gradually overcome the technical barriers based on every part of the flintlock.

Then, after gradually inventing and creating equipment that can produce these parts, as long as a skilled craftsman knows how to use these equipment, he can skillfully manufacture the corresponding flintlock parts.

Huang Yueying nodded, and the old craftsman fixed the polished alloy cylinder on the drill floor.Then align the drill bit with the center of the cylinder.Then firmly fixed the alloy cylinder, and then began to shake the hand pole on the drill floor.

This hand rod is a bit similar to the crank handle on an old-fashioned tractor. You have to shake it vigorously so that the drill bit can get in a little bit.

The drill bit is made of [-]-refined refined steel, which is much harder than the alloy copper pillar.The old craftsman shook his waist leisurely, drilled the drill bit in, and the alloy copper pillar slowly turned into an alloy gun barrel.

This is a meticulous job, the speed of rotating the remote sensor should not be too fast, nor too slow, it must be kept at this constant speed.

In this season when dripping water turns into ice, the old craftsman kept shaking the rocker, and beads of sweat the size of beans kept dripping on the ground on his forehead.

After nearly two hours, the barrel of the gun was drilled out. Li Chen picked up the barrel and looked at it carefully.

There are threaded lines in the barrel, which is rifling.Whether viewed from the outside or the inside, the barrel of the gun seemed to be one piece.

perfect.

It can even be called a perfect handicraft.

Although in some war-torn countries in the previous life, small workshops there could also produce gun barrels, but they were at least semi-mechanized.To produce a barrel by hand like this is definitely commendable.

The barrel, this is the most technical thing in the entire flintlock production process.As long as this thing can be mass-produced, the rest of the parts are nothing.

After all, although the flintlock is a cross-age product for the Three Kingdoms period, it is not an outstanding thing in the entire history of firearms.

The biggest advantage of the flintlock gun is that it replaces the front-loading firing method of the old-fashioned matchlock gun with flint and fixed bullets.

The advantage is that the firing speed is faster, which can overcome the shortcomings of the old-fashioned matchlock guns that cannot be fired in rainy weather.

After the barrel was finished, Huang Yueying took the barrel back into the office, and Li Chen followed in, only to see that the table was full of parts.

Obviously, these are all the parts of the flintlock.

The next task is to assemble it. In the past three years, Huang Yueying has failed many times, this time she must succeed.

Due to time constraints, all parts are unique and there are no substitutes.Therefore, Huang Yueying must be extra careful during the entire assembly process, otherwise all previous efforts may be wasted.

"King Qin, the assembly may take several hours. King Qin can go back first. I will send someone to deliver the flintlock gun to the mansion tomorrow." Huang Yueying said to Li Chen before assembling.

"It's okay, I'll just wait!" Li Chen said softly.

Seeing Li Chen's insistence, Huang Yueying didn't say much, and started to get busy with her own affairs.

Huang Yueying was busy with her hands, while Li Chen looked at her quietly. Sure enough, serious women are the most beautiful.

After so many years of getting along, it is impossible for Li Chen and Huang Yueying to say that there is no feeling between them.It's just obvious that Huang Yueying, a workaholic, is more interested in the gun in her hand.

Time is passing, and in the blink of an eye, three hours have passed, and at this time, the sky is completely dark.

The workers of the arsenal had already gone back. At this time, there were only Li Chen and Huang Yueying in the factory.

As Huang Yueying installed the last part, the world's first flintlock gun was born.

"boom!"

"boom!"

Obviously very satisfied.

"If King Qin thinks there is nothing wrong with it, then this gun can be finalized and mass-produced!" Huang Yueying said to Li Chen.

"Very good, very good!"

"It's finally ready for mass production!" Li Chen said excitedly.

"There is still more than a month until the Chinese New Year, and finally produced a sample before the year. It has been five years, a full five years, and Yueying has finally lived up to the entrustment of King Qin!" Huang Yueying said softly.

At this time, Li Chen walked behind Huang Yueying, put his arms around her waist from behind, and said softly: "It's been five years, do you know how I got here these five years?"

It's not that Huang Yueying doesn't like Li Chen, but because, without fulfilling his great trust, she naturally has no face to talk about love with him.

"what!"

"Not here!" Huang Yueying's delicate voice came from the office.

"It doesn't work here, just change to another place!"

"However, it's been five years, and Li Chen has been thinking about this moment for five years, how can he care about changing places!" Li Chen couldn't care less.
