Chapter 352

On the firecracker shooting range of the Carpenter Camp on the east bank of the North Baihe River in Yunzhou Fort.

The two sergeants brought up one side panel of the chariot and stood it in front of everyone, and stabilized it on both sides, while the other side was feeding the big bird gun with lead.

"Marshal, the pipe of this big blunderbuss is the most difficult to get through. The wall of the pipe must be thick and strong to prevent the chamber from blowing up, and the inside of the pipe must be smooth and straight so that it can be shot far and accurately. It takes a lot of work to drill and grind. If the master comes down in one month, it may not be possible to drill and grind it into one."

Wang Gancheng, the director of the Fire Gun Bureau, introduced the big gun, and Zhang Cheng also sighed softly. In this era, there is no industrial machine, and everything is done by hand, which is naturally slow.

This is still at his request. All craftsmen are first divided into various bureaus according to their skills, and then they are divided into work groups. At the same time, each bureau is equipped with a vernier caliper to regularly check the scales of each group of rulers, squares, and round rulers. , without the slightest mistake.

It is such a manual control standard, which was the only one in the late Ming Dynasty. When the country was founded in the early Ming Dynasty, all workshops were also extremely strict, and the ordnance produced was of high quality.

But at the end of the dynasty, the law of the cycle still cannot be escaped. Corruption in the officialdom will inevitably make the government inefficient, and the local tycoons and wealthy families will collude with the government to double the exploitation of the people. They are perfunctory in political affairs and military affairs. Task, how can you care about quality.

The poor quality of ordnance has directly led to a large number of soldiers preferring to use old and broken ones instead of new-made ordnance issued by the Ministry of War for safety.

In order to avoid this situation, Zhang Cheng put a number on each part, and searched according to the number to know who made it, and there is also a verification, only qualified ones can be put into the warehouse.

In addition, strict manual standardization is implemented. The regulations for each gun and armor are basically the same, and most of the parts can also be used interchangeably. Skilled craftsmen.

Although this advantage is not obvious in the short term, after a period of accumulation, after half a year or a year, the efficiency of this assembly line production method will make a big improvement, or even explode.

Here the big gun is mounted in the perforation of the box, which is a rectangular hollow up and down. The shooter puts the big gun on the perforation, and the whole person is hidden behind the box, so he can aim with peace of mind.

"boom!"

As the muzzle flashed, a puff of smoke instantly rose up. Fortunately, the barrel of this big gun was very long, so the smoke could not choke the shooter, and the medicine pool was also some distance away from the eyes, so it could not hurt the shooter's eyes either.

The big gun was drawn back, and the two sergeants were busy filling the big gun with ammunition. Zhang Cheng looked intently, and saw that the humanoid target 150 steps away was intact. It was obvious that the first gun had missed the target.

In the end, a total of five shots were played, and except for the first miss, the remaining four shots were all hits, hitting the target at four distances of 150 steps, 120 steps, [-] steps, and [-] steps.

According to experience, this big gun has no problem breaking through single-layer armor at 150 paces, and can break through double-layer armor at 120 paces. Although the distance is not as ideal as the sniper rifles of later generations, it is barely enough to deal with it.

"Wang Qiancheng, tell me how many guns our Fire Gun Army has produced in Yunzhou?" Zhang Cheng asked Wang Gancheng, the director of the Fire Gun Bureau.

Wang Gancheng replied tremblingly: "Reporting to the commander, so far we have made 250 six rods of the new Yunzhou blunderbuss, and by the end of August, we can drill and grind more than 240 rods."

Zhang Cheng nodded and ordered: "Wang Qiancheng, let me ask you about the 250 six-shot Yunzhou blunderbuss that have been made. If the guns are all remade into the Yunzhou blunderbuss style, how long will it take and how many materials will be spent?"

Wang Gancheng thought for a while before replying: "I'm afraid it won't be possible to remake the gun mechanism, but remaking it is not very time-consuming, and it will be faster than drilling and grinding the gun barrel."

"Then don't change it. These 250 six-shot Yunzhou blunderbusses can be packaged. I will send someone to pick them up in a few days. After that, they will all be made according to the regulations of the Yunzhou blunderbuss.

Also, the big blunderbuss is not easy to make, let's make [-] rods first, there is no rush, just make it slowly, and it must not affect the progress of the Yunzhou blunderbuss first style. "

After Wang Qiancheng received the order, Zhang Cheng called Shi Tiegen, the director of the craft camp, and asked him about the development of the drilling machine while walking to the artillery bureau's shooting range.

Only Shi Tiegen replied: "Commander, this drilling machine is really hard to get. I have tried two of them in the past month. It is different from drilling jade or other objects in the past. This gun barrel is long and extremely solid. And more importantly, the drilling and grinding should be smooth without any deviation.

It was originally a slow and delicate job, and the drilling machine made today, whether it is pedaled or hand-cranked, it is difficult to achieve a balanced and uniform speed of force and force, and it is difficult for even a master to control it. "

Zhang Cheng naturally knew in his heart that the design and manufacture of this drilling machine was indeed difficult, but now that he had this idea, he could no longer stop. Even if he continued to fail, it would be nothing more than drilling and grinding a few gun barrels less every month for him.

Immediately told Shi Tiegen: "Don't be afraid of failure, in this world, any new object is made by the predecessors after continuous pondering and continuous summarization.

Don't disperse the two scientific research groups of firecrackers and artillery, and don't be in a hurry. As long as you have a direction, go forward and try to get it. As for the Gunpowder Bureau, you should also be more attentive and form a scientific research group to tackle tough problems. ,
The future will definitely be an era of firearms duels. We can't stand still in this regard. Let's say that gunpowder was originally invented by our ancestors, but it has only been used to make fireworks for hundreds of years.

Besides, this blunderbuss is just an improvement after learning from the iron cannons of the Japanese pirates and the blunderbusses of the Lumi Kingdom. This matchlock gun is more convenient than the fast guns we used earlier, or the Huomen gun.
There is also the Franco cannon, which is better than ours in terms of production technology, but the sub-guns are pre-installed, and the direct firing method is much faster and more convenient than our artillery.

It can be seen from this that if you don't study this kind of thing, others will study it. We can't fall behind in this respect. Think about it, is this the truth! "

Shi Tiegen had long regarded Zhang Cheng as a god, but kept Zhang Cheng's meaning firmly in his heart. While speaking, a group of people had already crossed the Baihe River and were heading to the shooting range of the Artillery Bureau.

Zhang Cheng warned again: "The last time Zhang Guodong escorted Duchen Lu's coffin back to his hometown, he didn't bring back so many books. I left those about farming with Dushi Feng Yuanshan, and didn't all those related to firearms be sent here. Yunzhou craftsman camp.

Among you craftsmen, there are quite a few literate ones, so find these people and carefully grind the records in those books. If the books are not enough, I will send them to you.

Don't be afraid of failure, I don't limit the number of times you fail here, but you must ask the book office to participate in the whole process of each experiment, and record the process truthfully, so that you can summarize and find out the reasons, and then make improvements. "

"Yes, the villain has memorized it!"

Everyone came to an extremely wide field, where the Baihe River lies to the east, and there is an open space to the west, with no end in sight.
