Old Yang's name is Yang Limin. He is a draftsman in the technical department of Wanshan Factory and is also considered a veteran in the factory. However, compared with Chen Zhen's veteran, Yang Limin is rarely known in the factory. The main reason is that he rarely comes into contact with people and works hard when he gets a job. Sometimes he doesn't say a word all day. So when he mentions Yang Limin's name in Wanshan Factory, many people will ask, is there anyone in our factory?

Because of this, when Chen Zihao brought Lu Jiadong and others to Yang Limin's house, he still looked taciturn. Only when Chen Zihao and Chen Ziyue talked, he showed a long-lost smile and said a few words. However, Lu Jiadong felt that this old man with gray hair had an indescribable secret on his body.

"Uncle Yang, we are here to ask you for a favor!" After the greetings, Chen Zihao went straight to the point.

"When did you get so polite? Just say whatever you have!"

"Haha, that's right. A few of us want to develop a tactical guide rail system, but we don't know much about drawing the design drawings, so please help me, Uncle Yang!"

After hearing Chen Zihao's words, Yang Limin showed a kind smile: "We have started to invent and create, you guys can do it!"

"It's not my brother who did it!" As soon as Yang Limin finished speaking, Chen Ziyue, who was standing beside him, argued: "The idea was proposed by his cousin's husband, and the design was made by Brother Jiadong, and it has nothing to do with my brother!"

After hearing Chen Ziyue's words, Chen Zihao couldn't help but scratch his head awkwardly, but Yang Limin did not change any obvious, just staring coldly at Lu Jiadong and Wu Tianming sitting opposite:

"Is it what you think?"

"It is the result of our joint research!" Lu Jiadong replied with a smile, then took out a pre-drawn draft paper from his pocket: "Look, this is the sketch we designed!"

Yang Limin took the sketch from Lu Jiadong's hand and held the black frame's eyes. As soon as he glanced, his hand holding the sketch trembled slightly. Then he raised the sketch and asked Lu Jiadong excitedly:

"What type of aircraft are you using to missile mount?"

"Airplane? Missile hanger?" Chen Zihao was a little surprised, but he quickly said with a smile: "This is a tactical guide rail system installed on a firearm. You can actually think of the aircraft hanger. Uncle Yang, your imagination is really good!"

Yang Limin knew that he had lost his words, and laughed and said, then shifted the topic to the gun tactical guide system. Chen Zihao didn't think much about it, and showed off his posture as an academic professor and told Yang Limin:

"This guide rail system treats the gun as a weapon platform and some components as modules. According to different tasks and situations, these modules are integrated into the gun platform, just like a child building blocks, so that the tactical functions of the gun will be greatly expanded."

"Gun platform! Module!" Yang Limin's eyes lit up, then he picked up the drawing again and looked carefully: "Xiaohao, your ideas are very unique and advanced, just like a fighter, with different missions and different weapons, which is good, very good!"

"This is what Lu Jiadong said, but it was like I added the building blocks. Isn't it more vivid?" Chen Zihao's expression seemed to have proposed this plan. He probably decided to run wildly on the professor's road, and his integrity and so on fell all over the floor.

However, everyone in the house was amused by Chen Zihao's words. Fatty Luo patted Chen Zihao on the shoulder and smiled at him, saying that he finally saw someone thicker than him.

However, one of the few people here is an exception, that is Lu Jiadong. There is nothing else, because Yang Limin on the opposite side, he said about the plane twice before, and others may not have noticed it, but Lu Jiadong felt it was very unusual. At this time, most people had never seen what the plane looked like.

He was able to speak professional words such as hangers, which shows that Yang Limin should not be as simple as an ordinary draftsman. Although Lu Jiadong cannot determine what secret Yang Limin is hiding now, what is certain is that he is a person with a story.

The subsequent conversation mainly revolved around the specifications, shapes and other specific parameters of the gun tactical guide system. The conversation was mainly concentrated between Lu Jiadong and Yang Limin. After all, what they said was very professional and others could not even touch them. During the conversation between the two, Yang Limin felt that this young man named Lu Jiadong was indeed not simple.

In addition to the unique ideas, there are very practical plans in the use of materials, the maturity of manufacturing processes, and the trial installation conditions. This shows that this gun guide tactical system is not his fantasy idea, but the result of careful consideration and careful thinking. In the end, Yang Limin supported the black-framed glasses that were mounted on the bridge of his nose and said with admiration:

"It's really hope that Wanshan Factory can have someone like Xiao Lu!"

Lu Jiadong touched his nose and smiled: "This is not my own idea, it is the result of everyone's joint efforts!"

"Not arrogant or impatient, modest and cautious, good, good!" Yang Lixin showed a kind smile to Lu Jiadong, then pointed to the sketch and said, "I will help you, and in three days, I will take out the design drawings!"

"Three days? Wouldn't it be too nervous?" The drawing of the design is a systematic project, which is time-consuming and laborious. Even if the tactical guide system is not a grand military production project, there will be tons of design drawings without moving, at least dozens of artworks have to be drawn. Because of this, Lu Jiadong asked this.

Unexpectedly, as soon as Lu Jiadong finished speaking, Yang Limin held his glasses and smiled: "If it is a general design, it will take at least half a month. But Xiao Lu, you have already introduced all the data, technology, materials, and specifications clearly. This is no different from taking a real person portrait. It just so happened that I had nothing to do at hand recently, and I can definitely take it out in three days!"

Although Lu Jiadong didn't believe it very much, since Yang Limin said so, he couldn't refute it. So Lu Jiadong wanted to write down the specific data of the gun tactical guide for Yang Limin's reference, but he didn't expect that Yang Limin pointed to his head very seriously:

"What you said just now is very clear, I remember it all here!"

After hearing Yang Limin's words, Lu Jiadong was surprised. He just said all kinds of data like a chat, and he said it in a very unorganized manner. If he hadn't been familiar with the gun tactical guides, even he could not remember the data he had just mentioned, how could Yang Limin remember it?

Yang Limin obviously saw Lu Jiadong’s thoughts, and without saying a word, he said the data Lu Jiadong had said before, and now Lu Jiadong believed it, but he was not close to his feelings: Even though he had a golden finger in his hand, he could not underestimate the great people at this time.

In this way, the drawing of the design drawing was handed over to Yang Limin. However, while waiting for the design drawing, Lu Jiadong and the others were not idle either. They almost got up early and went to bed late. Although the labor service company had the technology and ability to process aluminum alloy parts, it was a civilian product after all, and there was still a big gap compared with military standards.

Take aluminum alloy processing as an example. Civil parts can be completed at one time using ordinary milling machines. The tactical guide rails that can be used for firearms are not possible. Comprehensive processing of lathes, milling machines, and planers are required. The processing accuracy is much higher than that of civilian parts. The entire process is like the machine tool machining center in later generations. However, at this time, Wanshan Factory did not have such equipment, so it can only be used to comprehensively process existing machinery.

In addition, there are high requirements in the production of component molds, tool application, heat treatment and other aspects. Therefore, the process of processing aluminum alloys in the labor service company was almost pushed back. Fortunately, Lu Jiadong was no longer familiar with this kind of gun guide system named Picatinny guide rail in later generations.

Therefore, there was no difficulty in preparing the process and production. The only thing that gave him a headache was that the machinery and equipment of Wanshan Factory were mostly products from the early days of the founding of the People's Republic of China, and a little better, it was also a Soviet imitation product from the 1960s. These equipment were not only old, but also had uneven technical levels, making it difficult to maintain processing accuracy.

Fortunately, there are also masters such as Li Deshun in Wanshan Factory. They are skilled in technology and rich in experience. These equipment can achieve the ultimate potential in their hands. Precision issues such as gun tactical guides are not a problem in their eyes.

Before he knew it, four days passed, and Yang Limin handed over more than 20 gun guide rail design drawings to Lu Jiadong as promised. Looking at the fine lines of the design drawings, Lu Jiadong sincerely admired Yang Limin's efficiency. The design drawings were completed and the process problem was solved. So Lu Jiadong found Wu Tianming, Fatty Luo and the Chen brothers and sisters came to the workshop of the labor service company and handed the drawings to Li Deshun.

Li Deshun took the gun guide design drawing and looked carefully for a while, and said confidently: "With Lao Yang's picture, it will be twice the result with half the effort. Xiao Lu, just let it go!"

"Since that's the case, then Master Li, let's start!" Lu Jiadong replied with a smile.

Li Deshun nodded, then took out a piece of aluminum alloy billet and put it on the lathe. With the roar of machinery and splashing sparks, the aluminum alloy billet was cut into rough outline by the lathe. Then Lu Jiadong and others ran to the military workshop for milling machine finishing, planer rough grinding, grinding machine fine grinding, and then went to the heat treatment workshop to heat-treat the workpiece that had just been processed. The tactical guide of the gun was completed.

"Jiadong, what's the name of this gun tactical guide?" Holding the newly developed gun tactical guide, Wu Tianming's face was filled with the joy of success.
Chapter completed!
