Super Chief

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

　　 "That's okay? Oh Maiga! Such a clay pot can melt the broken iron? Master Guardian, did you use any magic?"

　　 Shixiong glanced at Ferguson, and said gently: "Call the boss, and I will tell you how to do it."

　　 Lieutenant Ferguson stopped speaking immediately.

　　 Then, Lieutenant Ferguson saw that the molten iron was scooped out and poured into the mold that had been heated, and Lieutenant Ferguson's heart was the next words.

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

　　 While talking, after the mold was poured, there was still a lot of molten steel in the crucible, so Shixiong was about to let the remaining molten steel cool naturally.

　　 Lieutenant Ferguson looked constipated. Although he saw the whole process of steelmaking, he did not understand some of the key details. If you really cast the barrel by yourself in the future, you can't bother the guardian every time.

　　 But when I thought of the words the Guardian said just now, the constipation expression on Lieutenant Ferguson's face became much heavier...

　　 The next day, the barrel that had been completely cooled and the steel lump formed by the cooling of the remaining liquid steel were all removed.

　　 Shi Xiong took a piece of pig iron and grind the steel tuft, revealing the color of the steel tuft itself, it really is the kind of clean silvery white.

　　 This color already shows that it is a good piece of steel! Shi Xiong smashed a few more times with a hammer, and found that the toughness of this steel tuft was also very good, so he was completely relieved.

　　The barrel was made in one pot with this piece of steel. Even if this barrel is an absolutely unqualified barrel in later generations, it is definitely the top barrel in this age.

　　 Sure enough, when the mold was smashed open, a steel pipe with a length of one meter and a diameter of about 16 mm appeared in front of everyone.

　　 Ishikuma took a glance with his eyes and found that the barrel of the gun was still very straight. Although there are no tools such as a level when making the mold, but the dumb person has a dumb method. The simplest method of hanging wire is used, and its flatness is not worse than that measured with a level.

　　 When Ishikuma was making the mold, whether it was the outer mold or the kaolin mold in the center of the barrel, they were all made of several hanging wires, and the flatness was naturally guaranteed.

　　 Passed the barrel of the gun to Ferguson, who was probably thinking about the barrel last night, so this morning his eyes looked red and dark circles appeared.

However, this guy's spirit still looks very good, especially after taking over the barrel, he looked at it carefully for a long time, then knocked on the barrel with another piece of iron, and said after listening to the sound: "Guardian Sir, this is indeed a very, very good barrel. At least I didn’t see any defects in this barrel, and I can determine that this barrel is better than the barrel of the gun on my body. many!"

"you sure?"

"I am sure!"

　　 Lieutenant Ferguson's affirmative tone caused Shi Xiong to put a big rock in his heart.

　　 "Okay, since you are sure that this barrel can be used, let's talk about the design of the whole gun next. Let's go back to the room and say, it's a bit cold here."

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

　　 "Patrick, I want to ask you, do you have any thoughts on the gun that is about to be made? I must say how you can increase the range?"

Ferguson thought for a while and said: "If you want to increase the range of a rifle, you must draw a rifling in the barrel. Only a gun with a rifling can make the range longer. You said this yesterday morning. I. Now I’m thinking about the post-installation method you mentioned yesterday. I think that if the post-installation method you mentioned can be achieved, it will definitely have a huge benefit for improving the loading speed of the soldiers. It’s just that I haven’t thought of it yet. How to carry out after-loading, because if you want to use the after-loading method, you must open the gunpowder room, so that the airtightness of the gunpowder room cannot be guaranteed. Although the filling speed can be increased, the power of the gunpowder is caused by the inability to seal the gunpowder room Lower, it will reduce the power of this gun a lot, and may not even be as good as the standard rifle I use now."

　　 Hearing this, Shi Xiong was delighted. He really deserves to be the guy he likes, even if he is only twenty years old now, but after his own suggestions, he can already think of the pros and cons of the post-installation method. UU reading www. uukanshu.com

　　 So Shixiong smiled slightly and said, "What if you use the rotary valve locking method?"

　　 "How to lock the rotary valve?" Lieutenant Ferguson was stunned, and then stood there motionless, as if the words of the stone bear were a spell of petrification magic, and Ferguson was petrified in an instant.

　　 Shi Xiong felt happy again.

　　 This guy is really a capable person who will develop the Ferguson rifle in the future. He just mentioned the most crucial link in the Tifferguson rifle, which brought this guy into a state of "epidemic".

　　 In fact, the Ferguson rifle is no different from the Kentucky rifle except for the rear loading method. They are all fired rifled guns. However, it is precisely because of the addition of a post-installation method that this rifle has become a rifle of great historical and practical significance.

　　 Now all the rifles used in various countries are front-loaded guns, that is, the ammunition is loaded from the muzzle, and the entire barrel is airtight except for the muzzle.

　　 The Ferguson rifle has a round hole at the back of the barrel, which is the part of the gunpowder chamber, so that when the bullet is loaded, the projectile and gunpowder can be directly sent into the gunpowder chamber from this hole.

　　 Of course, if a hole is opened in the gunpowder chamber, if it is not blocked, the expanding air generated after the gunpowder ignites will inevitably pour out from this hole, and it is impossible to push the projectile out of the barrel at all. Therefore, how to close the loading hole after loading the ammunition has become a big problem.

　　 However, Lieutenant Ferguson solved this problem more than ten years later, allowing a real breech flintlock to appear in the world.

　　 And the key to his solution to the locking problem lies in the locking mechanism that can rotate!
