Show the sword, start from the guerrillas

Chapter 172 Chapter 171, the equipment has arrived, not much

Li Yuexuan really didn't want to follow the rhythm in a guy's book. But the Eighth Route Army had this condition, and the group members discussed for a long time to come up with the most suitable weapons for the Eighth Route Army, which were written in the book by the group leader. Therefore, the only choice he could make now was to follow the weapons discussed by the brothers in the group.

"It's a pity that we don't have a system that gives away equipment by killing enemies, otherwise it would be so cool." After spending two days to finish writing the information about Edward's wooden rifling machine, Li Yuexuan finally breathed a sigh of relief.

Of course, this does not mean that he can rest here, because since he wants to make a rifle, the most suitable one for the Eighth Route Army is undoubtedly the Type 81 Cavalry Rifle. Although Liu Da Lao is now leading the older generation of military workers to develop it, this does not prevent Li Yuexuan from "moving" the results of others in advance.

Although plagiarism is a bit shameless, if the Eighth Route Army can produce its own rifles and grenade launchers one day earlier, how many more Japanese soldiers can be killed with the wisdom of the veterans? What if the descendants of these Japanese soldiers have the ancestors of the Japanese Dongdian? How great a merit would that be? As for making some teachers lose the chance to be born? It seems that the Japanese never lack such talents.

Ahem, comrades who mistake electricity for heat, please tell us your names...

While there was still time, Li Yuexuan made new drawings. Since he was going to make the Type 81 rifle, he had to write out the most detailed parts drawings and processes, and even take the material issues into consideration.

What are the main materials of a bolt-action rifle? Of course, steel and wood! So, what kind of wood is most suitable for the buttstock and the gun body? First of all, the wood must have sufficient density, be hard, wear-resistant, heat-resistant, have good bending resistance, etc.

Therefore, woods such as paulownia and poplar, which have been selected by Li Yuexuan as the wooden handles of grenades, are not acceptable!

Anyone who has read Lao Wai's book knows that Lao Wai has a lot of complaints about domestic resources, at least in terms of firearms, the domestic resource points are really not ideal. Especially during the Anti-Japanese War, the Eighth Route Army was even more resource-scarce. Therefore, the only wood that could be chosen was catalpa wood. Well, catalpa wood is also called walnut tree. It is hard, wear-resistant and heat-resistant, and is the most ideal stock material that the Eighth Route Army could find.

Yang Gongxun and Zhang Lu, the brothers, have a say in this regard, because the planes and ink fountains they use are made of walnut. Li Yuexuan has also seen the planes used by the brothers, especially the side that rubs against the wood, which is really smooth.

But compared with the wood used in foreign guns, this is nothing. Germany's Mauser series uses European walnut, which is a precious wood; the Eagle's guns use black walnut, which is more expensive; the wood used by the Russians is white birch and yellow birch, which are not expensive, but they have a lot of them! Let's not talk about anything else. How many birch forests are there in the Outer Khingan Mountains that were ceded by the Qing Dynasty?
As for the Japanese's Type 38 rifle, the wood used was quite mixed, including walnut and birch. Anyway, the three northeastern provinces were surrendered without firing a single shot, so the Japanese got too much wood.

The Northeast had wood, coal, iron ore, grain-producing areas, and a complete Shenyang Arsenal, including a large amount of inventory, all of which were given to the Japanese, giving them the resources to invade the entire country.

Don't believe it? Li Yuexuan looked at the Type 38 rifles in the hands of his comrades. The data showed that the production place was Shenyang Arsenal. The grenade launcher and grenade launcher grenade were also made in Shenyang Arsenal.

After solving the materials of the buttstock and the gun body, the remaining materials are the barrel, bolt, firing pin, etc. Of course, there are also indispensable springs that need to be considered. For the problem of springs, you can temporarily find some from the scrapped guns and use them. Even the captured suitable bolts can be used directly. However, if you expand the production capacity of guns and produce springs by yourself, you must have your own spring steel smelting equipment, which is not something the guerrillas can do, so this requires the organization to consider.

In fact, for guns, the organization only needs to solve the problem of spring steel! Because, including the barrel steel, it can be directly solved with steel rails. Well, the steel rails are easy to solve. Our Eighth Route Army is also known as the "Road-Snatching Army"!

However, there is another material that requires high-quality steel, and that is the firing pin in the bolt. That's right, it is the firing pin that is driven forward by the spring when the trigger is pulled and hits the bullet primer. This material must be hard, impact-resistant, heat-resistant, and bend-resistant. In addition, the firing pin needs to be well protected during use. The Mauser series rifles have a special hole in the buttstock for the firing pin.

How to solve the problem of the material of the firing pin? Li Yuexuan found the answer from the data! Where is this place? It is Shanxi, a major coal-producing area! There are too many coal mines around. And the steel drills needed in these coal mines are good materials for firing pins! Of course, some tools on the Japanese trucks are also made of steel, and even file steel is OK.

A firing pin does not require much material, so the Eighth Route Army only needs to go around the surrounding coal mines and raid the coal mines' tool warehouses to get the materials for the firing pin.

Li Yuexuan held a notebook and a ruler, and drew the drawings of the parts one by one on the book. Then, he also noted the materials that would be used. When he was finally done, Captain Guo, who was protecting the transport company of the 772nd Regiment in the west, delivered the necessary equipment.

A small industrial boiler, with a steam engine, could drive a drilling machine and a lathe. This was the biggest help the organization gave. Of course, the workers who operated these equipment also came.

Li Yuexuan learned to operate a lathe in his later life. Although he had several scars on his face from burns from hot iron filings, and went back to his old job to open a clinic after working on the lathe for a year, his skills are still there.

So, after giving the newly written materials to Zhao Danian to study, he went to the small workshop next door. Then... he was a little dumbfounded. This lathe was different from the one he used... First of all, this lathe was very small, and the outer diameter of the processing was no more than 100mm, which was much smaller than the Anyang 6163 lathe he used. Then, the tool path and so on were different.

Of course, there is no problem in processing a small firing pin for this little guy, so that's fine.

"How are they? These equipments are good, right? In fact, equipment is not the main thing; talent is the main thing! This time, the organization sent us technicians, including several experienced senior fitters who have worked in the Jinling factory before!" Zhu Xingyu saw Li Yuexuan looking at the equipment with a slightly frown, and thought that he was not satisfied, so he stepped forward to comfort him.
