In fact, regarding the problem of gun barrels, using iron sheets to make gun barrels is not the best choice, because this is the process of making guns. And in terms of thickness control, it is not as easy to control as drilling iron rods. Although drilling
It may take a lot of effort and even take a long time, but the result is the best and the lifespan is the longest. With proper maintenance, it may be used until the end of the war.
The problem of bullet primer is no longer a problem for Han Cheng. At least the solution provided by the system is very suitable for now, and the rest is a problem of drilling.
Without professional equipment or special tools, according to common sense, the probability of failure will be very high. But after the system took over, the efficiency was greatly improved. At least the drilled holes were still very straight.
Here, it needs to be explained that the shotshells are not made according to the shotshells of later generations, but according to the length and width of the 7.92 caliber bullets. The purpose is to be able to modify the gun and carve the rifling when the tools are sufficient.
"Firing pin, spring...just do it!"
In fact, springs and firing pins generally require the same property, which is very high-strength steel. Early springs were actually made of piano wire. So the first thing you need to do is to meet the requirements of steel wire.
Then wind these steel wires into the size and shape you want, and then send them to heat treatment for shaping.
The springs Hancheng actually makes are small springs, and of course the most important thing is a big spring. The big spring is used on the bolt, and the corresponding firing pin also needs a very long length.
What's more important is the problem of the bolt mechanism. Even the simplest bolt mechanism is extremely complicated to design and manufacture. Although the guns made now are similar to shotguns and are simply used for hunting, a relatively long one still needs to be made.
The firing pin is used to fire shotshells.
"Rather than go to such trouble, it's better to do it first and talk about it later."
Han Cheng did it without any idea. The shotgun was relatively easy to install. The firing pin was installed, so the whole gun was very long.
There are also screws to make, and some screws need to be adjusted before they can be installed on the gun. Moreover, these are purely handmade screws, and there is no way to get standard screws.
As for the solution to the problem in Hancheng within the regiment, he actually didn't care about it at all. In fact, he was more concerned about the trend after the Xi'an Incident and the new developments of the Japanese army.
When you really get to that point, you don't have to passively understand, but you have to actively understand. Someone's plane might be hiding in the clouds, and if you accidentally drop a bomb, you'll be dead if you happen to encounter it.
.
It's not easy to live, but it's easy to die. These are troubled times.
"Well...in 1937, the Japanese invaded the Central Plains and opened the Marco Polo Bridge first..."
The only thing I can remember clearly now may be this ballad. Relying on the first few sentences, I can slowly sort out the movements of the entire Japanese army.
It is easy to forget this matter. Regardless of whether you can survive or not, the dates you have sorted out may be of some help to you.
"Well...that's enough, that's enough."
Han Cheng was in the livestock shed, drawing a rough map of China on paper, with the Japanese army's movement route in North China marked.
"Oh... I'm so helpless."
Looking at the marching route, it is certain that the surrounding land will be taken over by the Japanese army, and most of China will fall into the hands of the enemy. The Nationalist Government will move the capital to Chongqing, which will lengthen the supply line of the Japanese army and turn it into a war of attrition between countries.
This is what is written in the history books, but the specific facts cannot be verified. Maybe there are other reasons. Now, I am a witness to history, witnessing all this happening again. The pain they endured, I also have to endure
To endure it again, you have to experience victory again.
"Little comrade, you live in a nice place. Are you in solitary confinement or have you been deported?"
An old comrade wearing glasses came over and squatted beside the fire with several comrades.
"How can I not? This is a test for me. Look at it. The quilt and the ground are used as a bed today. Sometimes you can carefully consider the future path."
Han Cheng placed a small box open aside, which was filled with cotton, lime and other moisture-proof materials. Twenty-four rounds of shotguns were placed inside, and next to the shotguns was a new gun that had just been made.
"Yo? Is this a homemade gun?"
"Um."
"Why is it like this? Didn't the army give you a gun?"
"No, it belongs to the public and not to you personally. Can you just take it away? Besides, others have taken it away. If you want to practice shooting, you have to do it yourself."
This gun is still very new because the entire gun is dug.
"The guns in the army are all old guns. If the materials on hand were not enough, I would definitely be able to make a gun that suits me. At least this gun is still a bit inappropriate."
While sighing, I felt helpless. The gun was not distributed there, it was completely taken away.
"Not appropriate? Well, it's a little inappropriate."
"Old comrade, are you new here? Maybe you still don't know what kind of person I am."
"How could you tell that I'm new here? I didn't say anything?"
Why doesn't Han Cheng know so well? His situation is already known to the public in the Legion. Only strangers can chat with him alone.
"I am in the Second Red Army Corps, so I am just a street rat, because I am different from others. The regiment leader said that I am a counter-revolutionary and a reactionary. But I just told the truth. Is the truth really so ugly?"
Han Cheng did not think that his truth and historical facts were incorrect. Even if history gave him an answer, others did not acknowledge it and instead put the responsibility on himself.
"Yes, the truth is indeed unpleasant. Sometimes you need to pay attention to your methods at work. Otherwise, your situation will happen often. This time you just stink on the street, and maybe it will kill you next time.
"
The old comrade took out a bullet and was studying it, while Han Cheng was already lying down and ready to rest.
"Your gun is interesting, but are you sure you can shoot it?"
"The balance of science seems fragile, but precise calculations can make everything indestructible. I'm going to hunt birds tomorrow, and the old comrades can eat meat together in the evening."
I still have an optimistic attitude. At least with these more than 20 rounds of bullets, I can still shoot some birds and animals. Meat is not often seen. In the army, what we usually eat is wild vegetables, pickles and rice. The food is still quite good.
.
But don't tell me, the pickles are still quite delicious, at least much more delicious than the pickles sold in supermarkets or made by private individuals in later generations.
"Hmm... ok, pickles and steamed buns, plus meat tomorrow, you'll have a much better life than the average comrade. Okay, I'll make a meal tomorrow night, what do you need me to bring?"
"Just bring some condiments when your destiny comes. I can't get so many condiments. The cooking team won't provide them, so there's nothing I can do about it."
Han Cheng conveniently added a few pieces of firewood to the fire and then went to sleep. As for when they left, he didn't know.
