Lao Yang's name is Yang Limin, he is a draftsman in the technical department of Wanshan Factory, and he is also an old qualification in the factory, but compared with Chen Zhen's old qualifications, Yang Limin is little known in the factory, mainly because he rarely has contact with people, and he works hard when he arrives at the post, and sometimes he will not say a word all day, so when Yang Limin's name is mentioned in Wanshan Factory, many people will ask, does our factory have this person?

Because of this, when Chen Zihao took Lu Jiadong and a few people to Yang Limin's house, he was still that taciturn, only when Chen Zihao and Chen Ziyue talked, he showed a long-lost smile and said a few words, but Lu Jiadong felt that this old man with gray hair had an unspeakable secret.

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

"When did you kid become so polite, just say anything!"

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

After listening to Chen Zihao's words, Yang Limin showed a kind smile: "They have all started to make inventions and creations, you kid can do it!"

"It's not my brother's doing!" As soon as Yang Limin's voice fell, Chen Ziyue on the side argued: "The idea was proposed by my cousin-in-law, and the design plan was made by Brother Jiadong, and it has nothing to do with my brother's half a dime!"

Listening to Chen Ziyue's words, Chen Zihao couldn't help scratching his head in embarrassment, and Yang Limin didn't have any obvious changes, just stared coldly at Lu Jiadong and Wu Tianming who were sitting opposite:

"What do you think?"

"It's the result of our joint research!" Lu Jiadong replied with a smile, and then took out a piece of pre-drawn scratch paper from his pocket: "Look, this is a sketch of our design!"

Yang Limin took the sketch in Lu Jiadong's hand, helped the black-framed eyes, just glanced at it, the hand holding the sketch trembled slightly, and then he held the sketch up, and asked Lu Jiadong quite excitedly:

"What kind of missile pylons are you here?"

"Aircraft, missile pylon?" Chen Zihao was a little surprised, but soon said with a smile: "This is a tactical rail system mounted on a firearm, you can actually think of an aircraft pylon, Uncle Yang, your imagination is really good!"

Yang Limin knew that he had lost his words, smiled and snorted, and then shifted the topic to this firearm tactical rail system, Chen Zihao didn't think much about it, took out the posture of an academic professor, and told Yang Limin:

"This rail system is to regard the firearm as a weapon platform, and some components as modules, according to different tasks and different situations, these modules are integrated into the firearm platform, just like a child building blocks, so that the tactical function of the firearm has been greatly expanded. ”

"Firearm platform! module!" Yang Limin's eyes couldn't help but light up, and then he took the sketch again and looked at it carefully: "Xiaohao, your ideas are very unique and advanced, just like a fighter jet, different tasks and different weapons are attached, not bad, very good!"

"This is all what Lu Jiadong said, but it's like I added the building blocks, isn't it more vivid?" The look on Chen Zihao's face, as if this plan was proposed by him, is probably determined to run down on the professor's road, and the festival or something fell all over the ground.

However, the people in the room were amused by Chen Zihao's words, Luo Fatzi patted Chen Zihao on the shoulder, and said with a smile that he finally saw someone thicker than himself.

However, there is one person here who is an exception, that is, Lu Jiadong, nothing else, just because of Yang Limin opposite, he said twice about the plane before, others may not have paid attention, but Lu Jiadong felt very unusual, at this time most people have not even seen what the plane looks like.

He can actually say professional words such as pylons, which shows that Yang Limin should not be as simple as an ordinary draftsman, although Lu Jiadong is now unable to determine what secrets Yang Limin is hiding, but what is certain is that he is a person with a story.

After that, the conversation mainly revolved around the specifications, shapes and other specific parameters of the firearm tactical rail system, and the conversation was mainly focused on Lu Jiadong and Yang Limin, after all, what they said was very professional, and others couldn't interject at all, and in the process of the conversation between the two, Yang Limin felt that this young man named Lu Jiadong was indeed not simple.

In addition to the unique idea, the use of materials, the maturity of the manufacturing process, and the trial conditions have a very practical plan, which shows that this gun guide rail tactical system is not his whimsy, but the result of careful consideration and careful thinking, in the end, Yang Limin supported the black-framed glasses on the bridge of his nose, and said with admiration:

"Wanshan Factory can have people like Xiao Lu, I really see hope!"

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

"Not arrogant, not impatient, modest and cautious, not bad, not bad!" Yang Lixin smiled kindly at Lu Jiadong, and then pointed to the sketch and said: "I helped you with this, and after three days, I will take out the design drawing!"

"Three days? "The drawing of the design drawing is a systematic project, time-consuming, laborious and brain-consuming, even if the tactical guide rail system is not a grand military production project, there are tons of design drawings without moving, but at least dozens of drawings have to be drawn, which is why Lu Jiadong asked.

Unexpectedly, as soon as Lu Jiadong's voice fell, 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, processes, materials, and specifications, which is no different from taking a portrait of a real person, it just so happens that I have nothing to do with my hands recently, and I can definitely get it in three days!"

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

"You just said it very clearly, I remember it all here!"

Listening to Yang Limin's words, Lu Jiadong was very surprised, he just said all kinds of data like idle chat, and he said it very incoherently, if he wasn't very familiar with the firearm tactical guide, even he couldn't remember the data he just said, how could Yang Limin remember?

Yang Limin obviously saw Lu Jiadong's thoughts, and without saying a word, he said the data that Lu Jiadong said before word for word.

In this way, the drawing of the design drawing was handed over to Yang Limin, but in the process of waiting for the design drawing, Lu Jiadong and they were not idle, almost getting up early and soaking in the workshop, although the labor service company has the technology and ability to process aluminum alloy parts, but after all, it is a civilian product, compared with military standards, there is still a big gap.

Take the processing of aluminum alloy as an example, civilian parts can be completed at one time using ordinary milling machines, but can be used in the tactical guide rail of firearms, but no, lathes, milling machines, planers are needed for comprehensive processing, and the machining accuracy is much higher than that of civilian parts, the whole process is like the machine tool processing center of later generations, but at this time Wanshan factory does not have such equipment, so it can only comprehensively use existing machinery for processing.

In addition, there are high requirements in the production of parts and molds, the use of knives, heat treatment and other links, so the labor service company's previous process of processing aluminum alloy has almost been pushed to the beginning, but fortunately, Lu Jiadong is no longer familiar with this gun rail system named Piccatinny rail in later generations.

So in terms of weaving process production, there is no difficulty, the only thing that gives him a headache is the machinery and equipment of Wanshan Factory, most of which are products in the early days of the founding of the People's Republic of China, and a little better are also Soviet imitations in the 60s, these equipment are not only old, but also uneven in technical level, it is difficult to maintain processing accuracy.

Fortunately, there are still Li Deshun and other masters in the Wanshan factory, they are skilled and experienced, and these equipment can play the ultimate potential in their hands, and the accuracy problem such as the firearm tactical guide is not a problem at all in their eyes.

Unknowingly, four days have passed, Yang Limin handed over more than 20 firearm guide rail design drawings to Lu Jiadong as promised, looking at the fine lines of the design drawing, Lu Jiadong sincerely admired Yang Limin's efficiency, the design drawing was completed, and the process problem was solved, so Lu Jiadong found Wu Tianming, Luo Fatzi and Chen family brothers and sisters to come to the workshop of the labor service company and handed over the drawings to Li Deshun.

Li Deshun took the design of the gun rail and looked at it carefully, and said with confidence: "With Lao Yang's drawing, it will be more effective with half the effort, Xiao Lu, you will put a hundred hearts!"

"In that case, then Master Li, let's get started!" Lu Jiadong replied with a smile.

Li Deshun nodded, then took out a piece of aluminum alloy blank, put it on the lathe, with the roar of the machinery and splashing sparks, the aluminum alloy blank was cut out of the general outline by the lathe, and then Lu Jiadong and they went to the military workshop for milling machine finishing, planer rough grinding, grinder fine grinding, and then went to the heat treatment workshop to heat treat the workpiece just processed, and the firearm tactical guide rail was manufactured.

"Jiadong, what do you think is the name of this firearm tactical guide?" Holding the newly developed firearm tactical guide, Wu Tianming's face was filled with the joy of success.

Lu Jiadong looked at the first firearm tactical guide rail of this era, and was also very happy: "Military products have the tradition of naming the factory name of the product development plant, so let's call it Wanshan guide rail system!"
