In fact, the structure of the submachine gun is also very simple.
But it is often a very simple thing, and the last step is the most critical.
If it weren’t for Benjamin Goldberg, Zhao Chuanxin would definitely not be able to do it himself.
Although the gun fired, it failed to fire continuously.
Zhao Chuanxin pulled the trigger again, to no avail.
When he pulled the trigger, the firing pin was pushed by a compression spring to accelerate its forward motion. When the front end of the slide approaches the bullet, the firing pin is inserted into the bottom of the bullet and comes into contact with the fuze at the bottom. As the slide moves further forward, the firing pin ignites the gunpowder through the bullet and ejects the bullet.
When a bullet is fired, the recoil force acts on the bolt, pushing the bolt backward, causing the firing pin to remove the bullet from the magazine and ignite it.
This is probably the principle of a submachine gun, it is very simple.
But it is easier said than done.
The problem occurred when the recoil pushed the bolt.
A variety of minor problems emerged one after another, torturing Zhao Chuanxin to the point of death.
It was almost like pressing the gourd and lifting the gourd.
When it was almost noon, Zhao Chuanxin even wanted to smash the broken gun and give up.
Benjamin Goldberg’s eyes became brighter and brighter, “Master, I have realized it, I have realized it.”
Zhao Chuanxin was not angry, “You have already realized it. "It's morning."
"Ah this"
Marcus Nkrumah and Ning An had left early. They were too bored to even eat and went for a walk with Mi Shan. There are only two masters and apprentices left.
Zhao Chuanxin suffers from obsessive-compulsive disorder. The more something goes wrong, the more he wants to solve it.
But as the ideas in his mind became more and more perfect, Benjamin Goldberg wanted to prove that he was right.
The master and apprentice were a little confused.
"Master, try again, just once, it will definitely work."
Zhao Chuanxin hesitated, "Then, try again"
He continued to improve ,
But this time it just misfired.
"Fake, Fake"
Zhao Chuanxin threw the submachine gun to the ground and stepped on it hard with his feet.
"Bang"
This inferior submachine gun suddenly went off fire, which shocked Zhao Chuanxin.
I quickly looked at Benjamin Goldberg next to me and was relieved to find that he was not injured.
He silently picked up the submachine gun, put it on the table, and let out a long sigh.
Benjamin Goldberg was not afraid, but said happily, "Master, I understand, I understand, let's make a new gun"
""Zhao Chuanxin" Disciple, let the master take a moment and you will realize it again.”
At lunch time, Freddy Pavitt came to see their master and apprentice go back to eat.
Seeing a strange-looking gun placed on the table, he didn't take it seriously, because when he saw the frustrated expression on Zhao Chuanxin's face, he knew it must be a mistake.Defeated.
This was not what he expected.
"Master, let's eat first. We are not in a hurry to make guns."
Zhao Chuanxin felt relieved and stood up to leave.
At this time, a carriage entered the manor.
The visitor is Jesse Livermore.
He ran over in a panic.
"Ethan, something bad is going to happen."
Zhao Chuanxin hasn't heard good news for a long time,
grinding his teeth and making a long sound " What's wrong?"
"I can't find anyone"
"Why can't I find two-legged people on Wall Street?"
Jesse Liver. Moore ignored Zhao Chuanxin's teasing, "John Morgan, that old guy said, no broker on Wall Street is allowed to work for me, otherwise I will be his enemy."
"Which John Morgan has eaten the heart of a bear? "Leopard's courage" Zhao Chuanxin was furious. "I went to Wall Street to do it today."
"It's that J. Morgan who is a master of asset restructuring, proficient in financial business, and presided over the establishment of the monopoly of the United States Steel Company."
That's what he said Zhao Chuanxin knew who it was.
"This old man is immortal." Zhao Chuanxin wondered, "I didn't offend him."
"I think it's because of you. We seem to have fallen into a trap where someone carefully The purpose of the web of conspiracy is to make it difficult for us to move forward."
Zhao Chuanxin waved his hand, "Let's eat first."
At the dinner table, Jesse Livermore kept talking and criticizing. These consortia are not things, and they denounce the shameless behavior of the American bourgeoisie.
But Zhao Chuanxin remained silent.
Only for this meal, he ate very little.
After the meal, he smoked a cigarette in his chair.
Miao Cuihua came behind him and pressed his shoulders, "Don't be discouraged. The worst we can do is go back to China and start over. At worst, I will accompany you to farm. I used to farm, and in the past two years, my hands Only then did the cocoon recede."
In this era, the person who knows Zhao Chuanxin best is undoubtedly Miao Cuihua.
Zhao Chuanxin pulled the little hand on his shoulder and said, "Let me see."
Sure enough, there was no callus on the palm of his hand.
It has been well maintained in the past two years, and it is white, tender and soft.
"Does it look good? Go back to the house and take a look."
"Haha, wait no more, I have to make a gun."
Zhao Chuanxin ran away.
He found that the gap between the times in his heart was getting smaller and smaller.
That little line of defense has been defeated, and the last hold on is crumbling.
Miao Cuihua saw him walking out with the foreign snot baby and the foreigner named Jesse, smiled, and directed the servants to clean up the kitchen.
Zhao Chuanxin said as he walked, "Since the weapons workshop can play the trick of building plank roads and concealing warehouses, then financial operations can also be done."
Jesse Livermore is very smart, isn't he? Didn't think about that.
However, if you findOther agents, what else do you want him to do?
Zhao Chuanxin saw through his mind, and when he saw that he was silent, he said, "Thomas Lawson, that old boy has a lot of trouble. I can do more." Lending you a sum of money will be enough for you to make huge profits. Those who do big things, don’t always get hung up on the details.”
Jesse Livermore finally smiled, “Okay, but his means are limited. , more inclined to conspiracy, and sometimes bad things happen.”
“It’s done in his name, but he is the auxiliary, and you are the main one. I don’t care about anything else. I just want to make money.”
"I know what to do."
The problem was temporarily solved. After sending Jesse Livermore away, Zhao Chuanxin came to the table again, unable to do anything with the broken gun.
Benjamin Goldberg was 10,000 times more active than going to school. He had been sitting there waiting for a long time.
"Master, I promise, I have enlightened, and I will succeed this time."
"I will lend you some good words."
Zhao Chuanxin will re-cut Polished the parts and started a new journey.
What he is most afraid of now is Benjamin Goldberg, telling him to "enlighten".
Enlightenment means starting over.
After all, I have done it once, so I feel comfortable doing it again.
The original blueprint of the submachine gun has been changed beyond recognition by the master and apprentice.
In this era where "big bolts" and machine guns dominate, you can usually see many riflemen on the battlefield, shooting unhurriedly.
It was a lively fight for a long time, with zero casualties.
Why is Zhao Chuanxin called the God of War
He always fights against many enemies. The enemies usually suffer heavy casualties, which may be worse than on a battlefield where hundreds or even thousands of people are shooting at each other. The casualties were greater.
That’s why the enemy is afraid of him.
If he had a submachine gun, both he and the insurance team in Lugang Town would change the situation of the war.
And the submachine gun is just the first step.
It is imperative to invent the submachine gun.
Even if it is not currently suitable for large-scale deployment on the battlefield and is only used by Zhao Chuanxin himself, it must be developed.
He put away his impetuosity and discussed it seriously with his apprentice.
"Master, I have to use a stronger and more reliable material for the firing pin, otherwise it will always break down."
Zhao Chuanxin set his sights on beryllium copper.
Beryllium copper has high strength, hardness and corrosion resistance, which is better than high carbon steel, and of course more expensive.
Zhao Chuanxin gritted his teeth, "Fake, this time our gun heads, jamming plates, rollers, hammers, bores, triggers, and rate-of-fire selector levers are all made of beryllium, as long as they need to be rubbed frequently. Copper."
The cost may not be visible for a few guns, but if there are more, the cost will rise sharply.
He didn’t know how much impact his decision today would have on the military fan collecting community in the future
This time, six right-hand rifling lines were carved into the inner bore.
Gun headThe thickness of the rollers and the size of the rollers are all determined by the master and apprentice after repeated discussions.
Finally, Zhao Chuanxin began to assemble.
After installing all the parts, Zhao Chuanxin took a deep breath.
I pulled the charging handle above, but it was still a little frizzy.
There are three kinds of lubricants on the table.
One is a light lubricant for cars and carriages, which can also be used on manual bolt-action rifles.
One is high-temperature lubricating oil, which is produced by John Rockefeller's oil company and is specially used for high-temperature and high-pressure machinery.
The last thing is gun oil. This thing sounds professional, but it is actually made from animal fat, which will solidify at low temperatures.
Zhao Chuanxin thought for a moment, then disassembled the gun, dipped his hands in high-temperature lubricant that were not too dirty, and began to smear the parts and wipe them carefully with a coarse cloth.
It is very particular to oil the gun, because no matter what kind of lubricating oil is at this time, it cannot compare with the chemically synthesized lubricating oil of later generations.
Excessive oil will cause carbon deposits and slow down the burning speed of gunpowder.
Too little oil will not lubricate the gun.
Zhao Chuanxin knows a lot about wiping gun oil.
After taking care of it, Zhao Chuanxin reinstalled the parts.
This time he did it extremely seriously,
because he was not sure whether he could still maintain the patience to continue research if he failed again this time.
Everything is the hardest when you take the first step.
So, he had a sense of ritual, waiting for the final practice.
He put on the Fortitude Armor, pulled on the skull mask, loaded the ammunition, and pulled the charging handle.
Taking a deep breath, Zhao Chuanxin pulled the trigger under the nervous gaze of Benjamin Goldberg.
Chug tug tug tug
As the flames from the muzzle spit out, and as the metal frenzy poured out, Zhao Chuanxin's high-hanging heart also let go.
He let out the depression of the day.
Benjamin Goldberg jumped up from his chair happily.
He originally thought that fantasy could make him happy, but today he learned that the most satisfying feeling is when fantasy becomes reality.
In the villa, Freddy Pavitt was working on documents.
He writes freely, with well-organized handwriting and smooth and graceful lines. It is the Spencerian cursive script that was popular in the United States and Britain at this time.
Suddenly, he heard a series of rapid gunshots.
The sound of heavy machine gun fire was steady and low.
The continuous gunshots were rapid and sharp.
It was more like dense and orderly gunshots.
Freddie Pavitt's heart moved and he stood up in disbelief, "Impossible, could it be, could it be"
He knew what kind of gun Zhao Chuanxin wanted to research.
At this time, John Browning, the most famous weapons design expert in the United States, clearly said that was simply impossible.
ConnectExperts said so, how could Zhao Chuanxin be created by a layman and a child with no hair?
He threw the pen roughly on the table and walked out quickly. .
