The next morning, Zhou Chengru took Tang Yufeng to appear in the arsenal.

After half a month of development, ammunition production in the arsenal has been completely on track. All gun repair equipment has been produced, and other parts can be produced on a small scale except for the barrel.

Before Zhou Cheng could tell the gains from Taiyuan, the excited Kong Dewen took him to a room and then mysteriously opened a box: "Captain, deputy commander, these are three rifles that we produced ourselves assembled. Except for the barrel of the gun was removed from the damaged gun, all the other parts were handmade by us using equipment made by Lao Li. I'm waiting for you to come and test the gun!"

Three imitated 38 large covers were placed in the box. The gun body was polished very smooth by the workers, and a thick layer of gun oil was applied on it. At first glance, there was almost no difference between it and the 38 large cover seized by the troops.

Zhou Cheng looked like he couldn't put it down when he picked it up. He pulled the bolt and aimed at it. The more he looked, the more he liked it.

"Is it troublesome?" This is the question that Zhou Cheng is most concerned about.

"It's okay..." Kong Dewen replied with a smile on his face.

"Lao Li used a motor to assemble a lot of equipment. Because of the limited power, he could not perform cold stamping. I was wondering if we could perform hot stamping."

"The steel used for the artillery is very hard. The arsenal has stored several bombs. I used the gun barrel to create some rifle parts abrasive tools, heated the iron used for making the gun and stamped it. After the parts are stamped and molded, the workers will polish it, and finally confirm whether the finished product can be used."

"In the end, our approach proved to be very useful. You can get a good one by punching three parts on average."

"Although the pass rate is very low, as long as there are abrasive tools, the parts will be stamped very quickly, and unqualified parts can be re-stamped, so the production efficiency is OK, and there is no waste."

"Under normal circumstances, at least all parts of a ten gun can be produced a day."

"Then let's go and test the gun first!" Zhou Cheng couldn't wait for the order!

For a rifle, the most important and most loss is the barrel. As long as the barrel is fine, other parts will definitely be fine.

But for the poor and careless National Salvation Army, the arsenal has been produced from scratch, and now even rifle parts can be produced, which undoubtedly has great significance.

The test results were very satisfactory, and the performance of the three rifles was almost no different from the captured rifle.

If the problem of producing gun barrels can be solved, the arsenal will be able to manufacture its own guns on a small scale.

Although the limited output cannot even satisfy the use of the National Rescue Army, as long as the arsenal has this ability, the National Rescue Army will not have to worry about the blockade of the Japanese and puppet troops in the future.

Under no circumstances, as long as the national rescue army protects the arsenal, the Japanese and puppet troops will not be eliminated.

Zhou Cheng became more and more excited as he thought about it, and he quickly ordered: "Director Kong, Lao Li, these three rifles are just the barrels we produced by ourselves."

"We will go back to the arsenal immediately to solve the bottleneck of the production barrel, so that our national rescue army will no longer have to worry about the blockade of the Japanese and puppet troops in the future."

Kong Dewen knew better than anyone else about the problem of producing gun barrels in the arsenal. He immediately stared at Zhou Cheng and asked with his eyes lit up: "Captain, you got the drill bit and the broach!"

Zhou Cheng nodded and replied with a smile on his face: "Not only did he get a drill and a broach, but he also took back the two gunpowder experts you recommended."

"In addition, we were also fighting rabbits in the action, and we got back more than 500 barrels and more than 5,000 kilograms of special raw materials for producing gunpowder. Zeng Wenjing made a list and asked us to make it from the Japanese Taiyuan Arsenal."

"Comrade Zeng Wenjing told me on the way back: With these raw materials, our arsenal can immediately produce primer and launching medicine for bullets and shells, and cannonballs, and can also produce grenade fuses!"

"In this way, we can continue to expand the ammunition capacity of the arsenal and also create the grenade production line. If there is still a lot of gunpowder, we can also find a way to try the production of small-caliber mortar shells!"

Kong Dewen was so shocked that his mouth was almost closed. Zhou Chengyi pulled him to the arsenal after he finished speaking.

Seeing a soldier removing the drill bit and broach from the war horse, he quickly greeted Li Wenfeng beside him and said, "Old Li, this is the drill bit and broach we urgently need. They are all six or five caliber. You can install it on the drill press immediately. I will take the bristle barrel that has been polished in the past few days and see if the drill press you made can be used."

The blast barrel is recast by casting the used rifle barrel after melting it and then casting it with a mold. There are a large number of bubbles and burrs on the inner wall, which is far from meeting the requirements for the use of the barrel.

In order to make the inner wall of the barrel smoother and stronger, when casting the barrel, Kong Dewen deliberately adjusted the caliber to five millimeters, and the remaining 1500 was all expanded by the drill bit, and finally rifled the barrel...

Twenty minutes later, the drill press made a dull roar, and the drill bit that had just been installed immediately ran rapidly, looking similar to the drill press in the Taiyuan Arsenal.

Li Wenfeng quickly fixed the barrel to the drilling machine and operated the drill bit slowly approaching the barrel.

"Squeak squeak..."

The harsh metal friction sounded quickly, and iron filings with splashes kept flying out of the barrel.

Because the motor power is limited, the drill bit speed is far from meeting the requirements of the original drilling machine, and the temperature has to drop after working period. It took Li Wenfeng almost two hours to drill a barrel and then start rifling.

At this moment, Kong Dewen was counting the barrels brought back by Zhou Cheng, and his mouth was almost unable to close.

When raiding the arsenal, due to limited time and no ignition, the reconnaissance team packed all the good barrels in the repair workshop, only knowing that the number of barrels exceeded 500, and they didn't know what their specific caliber was.

On the way back to the defense zone, Zhou Chengru did not take a careful inventory because the barrels were all packed and fixed on the horse's back.

Until now, Zhou Cheng has seen the true face of these gun barrels.

Their number is indeed more than 500, but there are three types of calibers.

More than four hundred are the most common 38-cap barrels, more than one hundred are the crooked light machine gun barrels, and there are twenty air-resistant machine gun barrels.

These barrels alone can allow the arsenal to produce a reinforced battalion's pneumatic machine gun in a short time, and can also replace the barrels of all rifled light machine guns in the regiment.

"Captain, I decided that the arsenal will officially produce weapons and ammunition from tomorrow. Even if it produces ten new guns a day, it can produce 300 new guns a month!"

Zhou Cheng unexpectedly rejected: "Director Kong, I think the current top priority of our arsenal is not to produce new guns."

Zhou Cheng's words were completely beyond Confucius' expectations.

In his opinion, the arsenal is used to produce firearms, so that the troops can have a steady stream of weapons available, and the firearms can further expand the troops and increase their strength.

The regiment commander actually disagreed with the production of firearms, and Kong Dewen couldn't understand it.

Zhou Cheng directly explained: "Producing firearms requires a lot of manpower and resources, but the daily output is only ten rifles, so it is better to continue repairing firearms."

"Compared with the manufacturing of new guns, repairing damaged guns only requires remanufacturing of part of the parts, which requires very little manpower and resources, but the output can be increased by at least twice."

"We have an arsenal now, but the resources are limited. We must use our brains more and use the least resources to produce more weapons and ammunition!"
