Chapter 94

Ferguson watched with his own eyes the smashed pig iron slowly melt into yellow and white liquid iron in this big pot made of "mud". The expression on his face was wonderful.

"Is that ok? Oh, MAIGA! How can such a pot melt the broken iron? Guardian, did you cast any magic

Stone bear glanced at Ferguson and said gently, "call boss and I'll tell you how to do it."

Lieutenant Ferguson was silent immediately.

Then, Lieutenant Ferguson saw that the molten iron was scooped out and poured into the mold which had been heated all the time. What made Lieutenant Ferguson most excited was the next words of stone bear.

"Patrick, do you know how to make steel? Don't underestimate this pot of molten steel. After cooling, this is the steel with better material. In the future, if you want to make a rifle with longer range and greater power, casting barrel is a skill you must master. After all, the barrel is the core of a gun. Without a barrel of good quality, a rifle with great power and long range can only be utopian. "

In the meantime, after pouring the mold, there is still a lot of liquid steel in the crucible, so Shi Xiong is ready to let the remaining liquid steel cool naturally.

Lieutenant Ferguson looked constipated. Although he saw the whole process of steelmaking, he didn't understand some key details. If you really cast the barrel alone in the future, you can't trouble the guardian every time.

But at the thought of what the guardian said just now, the constipation on Lieutenant Ferguson's face became heavier

The next day, the gun barrel that had been completely cooled and the remaining molten steel formed a steel lump after cooling were all removed.

Stone bear took a piece of pig iron to grind the steel lump, revealing the color of the steel lump itself. It was really that clean silver white.

This color already explained is a good steel! Stone bear hit with a hammer a few times, found that the toughness of this steel lump is also very good, so he was completely relieved.

The barrel is made in one pot with this steel lump. Even if this barrel is absolutely unqualified in later generations, it is absolutely the top barrel in this era.

Sure enough, when the mold was broken open, a one meter long steel pipe with a diameter of about 16 mm appeared in front of the public.

Stone bear took aim with his eyes and found that the barrel was still very straight. Although there is no level instrument and other tools when making the mold, stupid people have stupid methods. The simplest hanging wire method is used, and its straightness is not worse than that measured by level instrument.

When Shi Xiong made the mold at that time, whether it was the outer mold or the kaolin mold in the center of the barrel, it was made with several hanging wires, so the straightness was naturally guaranteed.

He handed the barrel to Ferguson, who thought about it last night, so his eyes turned red and his dark circles came out this morning.

However, the spirit of this guy seems to be very good, especially after taking the barrel of the gun, he looked carefully for a long time, and then knocked the barrel with another piece of iron. After listening to the voice, he said: "guardian, this is really a very good barrel. At least I didn't see any defect in this barrel, and I can judge that this barrel is much better than the one on me! "

"Are you sure?"

"I'm sure!"

Second lieutenant Ferguson's affirmative tone put a big stone down in bear's heart.

"Well, now that you're sure the barrel will work, let's talk about the design of the whole gun. Let's go back to the room and say, "it's a little cold here."

Lieutenant Ferguson held the barrel tightly and followed the stone bear back to his room.

"Patrick, I want to ask you, do you have any idea about the gun to be made? How do you improve your range? "

Ferguson thought for a moment and said: "to improve the range of the rifle, it is necessary to pull the rifling out of the barrel. Only the rifling gun can make the range further. You said that yesterday morning. Now I'm thinking about the method of back loading that you said yesterday. I think that if you can really realize the method of back loading that you said, it will definitely be of great benefit to improving the loading speed of soldiers. It's just that I haven't thought about how to carry out afterloading, because if I want to use afterloading, I have to open the powder chamber, which can't guarantee the airtight of the powder chamber. Although it can improve the loading speed, the power of the gun will be reduced because the powder chamber can't be airtight, It may not even be as good as the standard rifle I use now. "

Hearing this, the stone bear was happy. He really deserves to be the guy he likes. Even though he is only 20 years old now, he has already been able to think of the advantages and disadvantages of the back loading method through his own suggestions.

So the stone bear said with a smile: "if you use the rotary valve locking mode?"

"Locking mode of rotary valve?" Lieutenant Ferguson was stunned, and then stood there motionless, as if the stone bear's words were a magic spell, which petrified Ferguson in a moment.

The stone bear was happy again.

This guy is really the capable man who will develop Ferguson rifle in the future. He just mentioned the most critical part of Ferguson rifle, and let this guy enter a state of "Epiphany".

In fact, there is no difference between Ferguson rifles and Kentucky rifles except for the rear loading method. They are all self-contained rifles. However, it is precisely because of a way of back loading that this rifle has become a rifle of great historical and practical significance.

Nowadays, all rifles used in various countries are front loaded, that is, ammunition is loaded from the muzzle, and the whole barrel is sealed except the muzzle.

Ferguson's rifle has a round hole in the back of the barrel, that is, the part of the powder chamber, so that the bullet and powder can be directly sent into the powder chamber from the round hole when loading.

Of course, a hole is opened in the powder chamber. If it is not blocked, the expanded air generated by the ignition of the powder will inevitably pour out from this hole, and it is impossible to push the projectile out of the barrel. Therefore, how to close the loading hole after loading ammunition has become a big problem.

However, it was more than a decade later that lieutenant Ferguson solved this problem and made a real afterburner appear in the world.

And the key to solve the locking problem is the locking mechanism that can rotate!
