Show the sword, start from the guerrillas

Chapter 176 Chapter 175, Getting Ready, It’s the New Year
With the support of the people, there is no need to worry about the catalpa wood for the time being. At least before the first rifle is made, there is enough catalpa wood! As for the source of catalpa wood in the future? ? When the soldier workshop can produce rifles on its own, catalpa wood will probably not be in short supply!
"Come, come, take a look. Catalpa wood can be exchanged for guns and bullets. As long as you have five catalpa wood boards that are two inches thick, three feet wide, and ten feet long, you can exchange them for a rifle and five bullets."

Well, when the time comes, just spread this news out, and Minister Zhang’s logistics department will be filled with elm wood.

We will talk about the matter of the elm wood later. Now Li Yuexuan has transformed into a hardworking little bee, running back and forth in the yard of Liangjia Village, which is specially used as a military workshop.

"Comrade Youshun, the steel requirements for this gun barrel are very high. Is it inappropriate for us to use steel rails to make it?" Huang Tianyang was a foreman in charge of firearms in the Jinling Factory, so he raised the question.

"In theory, it would be the most appropriate to import their gun barrel steel from abroad, or we can make steel ourselves! However, our conditions are like this, so we can only make do with what we have! Let's use steel rails. As long as we can ensure that one gun barrel can fire 500 or even 300 rounds of bullets, our gun will be usable! You have to understand that the main force can only fire 5 rounds of bullets in one battle."

After Li Yuexuan finished speaking, he thought for a while and continued: "The barrel of this gun is not the key. The key is the material and quenching of the firing pin. I have already noted that the best material is to find the firing pin from the Japanese rifles, but the quantity is hard to say. We can't buy firing pins from the Japanese, right?" At this point, Li Yuexuan thought of the Osaka Division, and it seemed that it was not impossible.

"So, the first thing to be solved is the firing pin problem. Well, the report has been submitted. How about you try the tool steels imported from abroad first! Well... make some firing pins first, put them on the Type 38 rifle cover, and test the strength problem!" Li Yuexuan knew the answer but didn't know how the answer was obtained, so he could only say this.

He heaved a sigh of relief only after Huang Tianyang and his team went to study the production process. He then took the drawings of the Type 81 rifle and continued to study what shortcomings there were.

Well, as the first standard rifle of the Eighth Route Army, the Type 81 rifle naturally has defects. The first one is the poor quality of the material, which cannot be solved unless there is a smelter in-house.

Secondly, it is too short, which is a disadvantage in bayonet fighting. Although the gun is 1120 mm long, a little longer than the 1110 mm of the Zhongzheng rifle, the bayonet of the Zhongzheng rifle is specially lengthened for bayonet fighting. The bayonet of the Type 1510 rifle is a three-edged bayonet fixed on the muzzle. Although it is easy to fold and unfold, there is no need to worry about the bayonet being lost, which is very suitable for mountain warfare. However, the length of 1680 mm after unfolding is much shorter than the length of mm of the Type rifle.

An inch longer, an inch stronger. Li Yuexuan himself chose the longest Mosin-Nagant rifle, in order to gain an advantage in bayonet fighting. So, of course, he would make improvements when drawing the picture.

I remember when he was reading the book, he even found some information and sent it to the group to remind a certain author, such as the way to fix the bayonet needs to be improved, etc. So, Li Yuexuan copied the information he found at the time and used the best design when drawing. Another way is to lengthen the length of the barrel, and at the same time, the length of the three-edged spike can also be lengthened.

His improved blueprint made the length of the rifle reach 1600mm after unfolding, which was only 8cm shorter than the Type 8 rifle. This cm length could be compensated by the height and arm length of the soldiers.

As for the shooting accuracy after the barrel is lengthened? With the auxiliary panel to help calculate the trajectory, there is naturally no problem. The key is that the accuracy of this gun itself is not very strong. It is good enough to guarantee an accuracy of 300 meters.

In addition, the early Type 7.92 horse rifle used 6.5mm bullets, but later it was changed to 6.5mm Arisaka rifle bullets. Why? It was for logistical support. After all, the main combat of the Eighth Route Army was to fight the devils, and most of the captured bullets were 6.5mm. Therefore, Li Yuexuan directly used mm caliber bullets. One advantage of doing this is that you can copy the bolt design drawings of the devils. If the bolt is damaged on the battlefield, you can find the broken gun of the devil and use the parts. Well, bolt-action rifles, in fact, there are not many differences in the specific structure. They are all rotating and pulling designs. The specific details of the bolt are the eggshell hook differences between flat-bottom bullets (Mauser rifle bullets), semi-flange bullets (Arisaka bullets), and flange bullets (Mosin-Nagant bullets).

Another advantage of this is that the barrel of the Type 7.92 Cavalry is short, and the 6.5mm bullet has more powder, which will cause a large muzzle flame and even affect the stability of the trajectory. The mm Arisaka rifle bullet has less powder, less muzzle flame, and less recoil, which is more suitable for the Type Cavalry. Of course, if the Japanese reduced-powder version of the machine gun bullet is used, it will be more suitable.

For several days, Li Yuexuan stayed in this yard, helping to deal with various problems. Whether it was a problem with the machine or processing, Li Yuexuan would take care of it.

As the days passed, Huang Tianyang and his team had already developed specific production processes for the various parts of the rifle, and even hammered out some of them. On Hai Datong's side, with the help of the carpenters, parts had been processed one by one. Hai Datong even found a Type 38 rifle barrel as a blueprint and drew the pitch line on a wooden round bar.

Then, the skill of a senior fitter was revealed! Hai Datong used simple tools to carve a master pattern of the pitch line on this wooden stick. With this wooden stick as the master pattern, the rifling pitch of the future barrels will be produced based on this standard.

Days passed like this, and then it was the end of the year! Yes, the Spring Festival was here, and the guerrillas stopped some work, allowing the comrades to rest peacefully for a day, which was considered the New Year.

Of course, the New Year's Eve dinner still has to be sumptuous! So Luo Wei took the lead, led by Yan Jinghuai and other soldiers from the cooking squad, and took the women in the village to make a lot of dumplings stuffed with wild boar and cabbage, so that the comrades could also have a New Year's Eve meal.

Of course, the people did not help for free. Those who had children at home brought them to eat together, and those who were alone also ate together, so that everyone could improve their lives.

There were no sounds of firecrackers, no flying fireworks, and even no beating of gongs or drums. New Year's Eve passed in such a quiet and deserted way.

The next day, the first day of the new year, after everyone greeted each other, the nephew held a lantern - as usual!

Well, those who need to tinker with the equipment should tinker with the equipment, those who need to tinker with the parts should tinker with the parts, those who need to tinker with the explosives should tinker with the explosives, and those who need to train should train... In short, you can't be idle in the new year, because everything is done in preparation for better fighting against the Japanese devils.
