Show the sword, start from the guerrillas

Chapter 177 Chapter 176, Production, the grenade came out first
Ding ding dong, ding ding dong...Since the first day of the new year, Liangjia Village has been emitting such rhythmic knocking sounds from time to time. (Old book friends can skip this)
On the edge of the woods outside the village, a shed with ventilation on all sides had been built, and inside it were two red stoves and an anvil. Outside the shed, a three-meter-high frame was built with thick wood, and two steel pipes were placed high up, with a pulley block hanging in the middle of the frame.

The iron buckle under the pulley is connected to a steel wire rope, which is connected to a hammer head weighing dozens of kilograms. The hammer head is fixed by two upright round steels from the grooves on both sides of the hammer head, so that the hammer head can only move up and down in the space formed by the two round steels. Of course, under the hammer head is a square anvil.

Hululu... A strong man from Yinjiulang Village kept pulling the bellows back and forth with both hands, blowing sufficient air into a red furnace. The red charcoal fire was blown brighter and brighter, burning the steel rails on the fire mouth gradually red, and finally became translucent. Then someone lifted the two ends of the steel rails and pushed them from the furnace to the other end.

"One, two, three... go..." With the help of the slide trolley, the steel rail was successfully pushed onto the anvil, so that the red-hot heated area was directly below the hammer head.

"One, two, three... up..." A strong man twisted the handle of the windlass vigorously, causing a brown rope to wrap around the windlass. As the rope became more and more wrapped, the heavy hammer head was lifted up.

"Everyone, pay attention. Put on the cutting tools..." The old master in charge of the pliers shouted, and a man exerted his strength with his waist and abdomen, and lifted a thick wooden stick connected to a sharp steel cutting tool onto the anvil.

Then, the sharp side of the cutter was aimed at the reddest and brightest part of the rail, quietly waiting for the hammer to land.

"Fall..." The old master yelled, and the sturdy man who had just turned the windlass let go of the crank in his hand and quickly turned his body to the side to avoid the blow of the crank. The crank, which had lost control, was driven by the force of the falling hammer head and began to turn.

Duang... The hammer hit the rail hard, leaving a deep mark on the red surface of the rail.

Then, the hammer head is twisted up, dropped, raised and dropped again... the rail is turned over... hit again... Finally, the rail is cut in the middle and becomes two shorter rails.

This kind of work needs to be repeated continuously by this hanging hammer until the rails are cut into the appropriate length, and then it will move on to the next process.

A rifle requires a lot of parts. The biggest part is actually the round steel used for the barrel. People will forge the shortened steel rails to make them longer and rounder, and finally make them into suitable round steel forgings. This is only the first forging process of the barrel.

Not only do we have to make the barrel blank here, but we also have to use another hammer to make the bolt blank, the striker blank, and other parts of the chamber blank.

After these blanks are forged, they will be sent to the village and forged by several other red furnaces to become precision forged and die forged parts. Some smaller parts, such as triggers, which do not require high dimensions, can basically be used after die forging and deburring.

For parts like firing pins, they need to be machined on a lathe to finish turning the spring platform and other parts. There is also the spring sleeve of the bolt, which needs drilling and other processes to finally become a usable part.

The other thing is the barrel. The lathe removes the black skin on the outer circle and both ends to make it smooth. Then, it is drilled, the inner diameter is determined by precision lathe, and the rifling is cut by the rifling machine... In short, a gun does not have many parts, but everything starts from scratch, and it cannot be made in a day or two.

The rifle was not easy to make, but one thing was made. Yes, it was a grenade, and the finished product was seen on the sixth day of the Chinese New Year.

Early in the morning of that day, the silent Chen Mo found Li Yuexuan and took him to the third house at the south entrance of the village, where grenades were made.

As soon as he entered the room, Li Yuexuan saw a row of grenades of different heights placed on the table outside the north room window. The black shells were shining faintly in the sun.

"Captain Peregrine, look, these eight grenades are the results of my research during this period! The largest one was made when I was in the Jinling Factory, imitating the German long-handled grenade. The smaller one is the standard of the Gong-made grenade, and this one looks like the Jin-made grenade. The remaining five are based on the No. 8 drawing you gave me, and they are loaded with Kaizi explosives."

"These two, the ones with big bullets, were made according to your suggestions. They are filled with 4 taels of black powder. The shell is very thin, and fragmentation grooves are added." After Chen Mo finished speaking, he remained silent.

"This..." Li Yuexuan first picked up the imitation German long-handled grenade, looked at it, and put it down. This grenade was longer, heavier, and more powerful, but it had no practical use. Then, he also took the Jin-made and Gong-made standard grenades in his hands and weighed them, and finally picked up the grenade he designed.

How do you say it? Compared to the original Jin-made grenade, Li Yuexuan's grenade is better! He said it was a copy of the Jin-made grenade, but in fact he was referring to the famous Type 67 grenade, which has more than one billion. Yes, that's it! However, in order to adapt to people's habit of using grenades at that time, the delay time was set at 6 seconds.

Then, the Type 67 grenade had too little charge, only 38 grams of TNT, and the number of fragments after the warhead exploded was only more than 100, which was a bit less powerful and heavier, weighing a full 600 grams. So, he first changed the material of the wooden handle to lighter wood, and shortened it to reduce weight. The charge was the same as the Type 77 grenade, increased to 70 grams, and fragment grooves were added to the grenade shell to reduce the weight of the shell.

Of course, since it is impossible to make the shell out of steel plates, the weight of this grenade can only be maintained at 9 taels. However, the number of fragments can be increased to more than 200, increasing the lethality.

How could Li Yuexuan modify the grenade? ? With the information and the auxiliary panel to help with the calculation, how could he not do it? After all, what does a grenade have? Pull-fire fuse, fuse, detonator, explosive, shell, handle, done!

He checked the grenades with the auxiliary panel and found nothing wrong, then he picked up the last two large grenades with small wooden handles. Well, this is the one-in-two-piece grenade that Li Yunlong complained about, but now this grenade has more explosives and fragmentation grooves, so it is not one-in-two-piece, there are at least dozens of fragments!
"Ahem, Comrade Chen Mo did a good job. These grenades are good! Let's go and test their power, and then we can start production! You take them to the shooting range, and I'll go find the captain!" After Li Yuexuan finished speaking, he went to find Zhao Danian and the others.

Well, now that we have achieved results, we should show them off, right?
