Yaro is going to make bullets first.
Although bullets are notorious and difficult to make, in principle, they are not complicated.
Analyze the process of bullet excitation.
After the primer (or detonator) is ignited by impact, the flame is transferred to the propellant through the detonation hole, and the propellant quickly detonates, generating high-pressure gas and pushing the top solid warhead.
The primer (or detonator) is the fuse, the cartridge case is half of the barrel, the propellant is placed in the cartridge case, and a solid warhead is plugged on top.
——It is exactly the same as the firing mode of the earth artillery!
A bullet basically consists of four parts: warhead, cartridge case, propellant, and primer (or detonator).
The best choice for cartridge cases is brass.
The choice of warheads is much wider, the common ones are copper, iron, and lead, the less common ones are silver and gold, and the legendary ice, glass, and ceramics.
Considering the cost-effectiveness issue, Rialro still chose brass as the raw material.
The propellant can directly use granulated sugar gunpowder.
The primer is divided into two parts. One is the internal ignition material, which needs to be detonated upon impact. Nitroglycerin can be used here.
In addition, the external wrapping material can also be made of brass.
Brass has a soft texture, good ductility, and a certain degree of strength, so most bullets are made of brass.
The warhead is just a solid piece of brass. You can first make a copper rod, then cut it off one by one and process it into a shuttle shape one by one.
Two small holes are reserved at the lower end of the cartridge case for ignition, and a groove is left at the base, which is the reserved position for the primer.
According to the structure, primers can be divided into two categories: berdan primers and boxer primers.
The Bodan-style fire base and primer are integrated, while the Boxer-type fire base is integrated with the cartridge case.
The fire platform is the impact point of the gunpowder in the primer after the firing pin strikes the bullet. It can work with the deformed primer shell, similar to the flint of a flintlock gun, to "squeeze" the gunpowder in the primer.
There is not much difference in the use effect of the two fire platforms. Yarrow chose the Boxer-type primer. The fire platform is a small raised dot in the middle of the groove of the shell base, because the primer of this kind of fire platform is easier to make. More convenient.
The final primer is a small bowl the size of a small button. After placing the nitroglycerin, you can cover it with a thin button lid.
If you want to do your job well, you must sharpen your tools.
Make the template tool in advance so that the bullets you make will be the same size and there will be no problems when firing.
Just like the fire platform is slightly larger than the groove under the cartridge case, it can be stuck using the toughness of the metal itself.
For the same reason, the warhead is 0.2-0.3 mm thicker than the barrel.
If the accuracy is not enough.
If the warhead is too large, it will cause jamming and explosion.
If the warhead is too small and the air tightness is not enough, high-pressure gas will be squeezed out from the edge gaps, which will cause damage to the kinetic energy and reduce the lethality of the bullet.
Therefore, the most important tool is a manual press. It is not complicated, just a large vise that borrows the principle of leverage, but requires sufficient precision.
As long as a copper pipe of appropriate length is heated and put in, the vise is tightened with brute force, and then hot melting and mold closing are used to successfully produce a cartridge case.
The tools made by Yarrow are all made of self-refined steel, which is not strong enough. After a few times of use, the punching mold of the cartridge case will be slightly deformed, so it needs to be constantly adjusted and repaired.
Time passes unconsciously.
…
The rising sun broke through the thick dark clouds, spreading warmth to the broken earth.
Facing the golden sunshine, the people in the ruins seemed to be waking up from a dream, and looked at the surrounding ruins in confusion.
"What happened?"
"Oh! My head hurts!"
"My hand! Why is my hand gone?"
"What happened last night? Why were so many people injured?"
"I'm so tired, I feel like my body has been drained."
…
Before the crazy noise subsided, an even louder noise broke out.
The harsh sound woke up the busy Yaro.
He glanced up at the wooden window, and the soft light hit his face, causing him to squint his eyes slightly.
"It's dawn."
The green buds sprouting on the wooden windows trembled slightly in the soft warm breeze, and through the lazy light, mottled little dust particles were playing and playing.
The gentle sunshine seemed to be filled with rich and sweet wine, and the biting cold that had been entangled in it instantly melted away.
Unknowingly, Yaro closed his eyes.
The pain in his head gradually became weaker, as if a heavy burden had been lifted off him. The feeling of relief made him drunk without drinking.
When he came back to his senses and saw dozens of shining golden bullets on the table, Yaro couldn't help but smile bitterly.
"You haven't even made the firearms yet, and you haven't even tested them in actual combat. Are you already making so many of them?"
However, this also shows that all the production steps have been sorted out by Yaro.
If necessary, Yarodu can directly take these utensils out and let servants or recruit others to make them.
Of course, a better way is to directly design a fully automatic production line.
Just as Yaro was thinking about these issues and cleaning up the room, there was a sudden knock on the door outside the house.
"Lord Yaro, are you finished?"
Baron Clare?
What is he here for?
Although Yaro was doubtful, he quickly put all the bullets into the space ring, then turned around and opened the door.
Baron Claire still hasn't taken off his military uniform, his face is cold, his eyes are sharp, and he exudes a violent aura:
"Lord Yaro, I'm sorry to bother you. I have something I want to ask you."
Baron Clair's mood was not directed at Yarrow. This was evident from the fact that he did not wear it and still
Fortunately, Yaro also had a lot of news that he wanted to tell him.
Although Yarrow is also involved, he will not be arrogant and take everything on himself.
After all, the protagonist of this incident is the earldom.
At the same time, the earldom is not a fat sheep that can be completely slaughtered.
They also have a large number of people, a Skaro Fortress that can withstand an empire's attack, their own army, and formal knights that can rival mid-level apprentices.
Thinking of the Red Ranelli who plotted against him, Yaro's eyes flickered, he glanced around, and then said:
"What do you want to know?"
"Lord Yaro, do you have any clues about Ying Xiao?" Baron Claire asked in a deep voice.
Yaro: "Didn't the spy, your personal bodyguard, Miles, give an explanation?"
"Last night, he died inexplicably."
"Inexplicable?" Yaro thought thoughtfully.
Baron Claire's face became even more ugly: "Yes, his whole body turned into blood!"
Blood?
Isn't it the same thing after the bloodline apprentice who betrayed the Fernando family died?
Wait... Whose order did Miles, Claire's personal bodyguard, follow?
