"This longitudinal rib structure seems to be stronger than the transverse rib!"

By the Yan'an River, looking at the first boat that came out, Lin Zhaocai fell into deep thought.

According to Yan Zheng's instructions, they used the keel longitudinal wooden rib structure to create this small boat with a canopy structure.

Although the longitudinal wooden ribs of the boat are slightly shorter, the speed at which it can be built still surprises Lin Zhaocai and Liu Chengyun.

Before the construction of the whole ship, it was reasonably divided into several areas, each of which was made of uniform prefabricated panels.

After the size is determined, the requirements are sent directly to the first wood factory, and the first wood factory will process the required prefabricated panels.

Then they assemble it, and the assembly process is just a minor repair of the prefabricated panels.

And some prefabricated panels are not the right size, and there are also people who are responsible for recording. Any prefabricated slab that has been repaired is also specifically recorded.

Finally, the keels, ribs and planks used throughout the ship were numbered and written on a table.

The back is a description of each numbered wood, including the size, thickness, and even a note: the structure of the place is more demanding, and the master said to use the wood as much as possible!

All this, in Lin Zhaocai's view, is very incredible, and it is like subverting his original shipbuilding experience.

And the students who do this work can easily translate the experience of word of mouth into data and words by simply learning to use numbers and how to use tables.

Lin Zhaocai was afraid that the craft would be learned at first, but after seeing it, he couldn't wait to communicate with these students more, hoping that they could use this method to get out their shipbuilding skills.

"If it is built according to the method here, I am afraid that it will be a small boat like this in a day or two!" Liu Chengyun said in a daze.

Yang Fuyun stood with his hands in his hands, frowned and said, "I have been sharpening wooden planks before, but now I understand that in fact, in the wooden factory, everyone's work is similar!"

The three of them all looked into the distance, and their eyes were a little lonely.

Liu Chengyun sighed and said: "It seems that we can't hide the shipbuilding technology!"

Lin Zhaocai nodded: "That's right!" After a few days in Dongfan, I realized the profundity of the ingenious things in the world. I'm afraid that the king of others may not be able to look at this bit of craftsmanship! ”

The two looked at each other, and there was a faint sense of loss, as if something that was originally something to be proud of had been crushed.

…………

A moment later, the three of them came to the Red Room to resume their lives.

As soon as they entered the red room, Lin Zhaocai and Liu Chengyun knelt down with a snap.

Yan Zheng was stunned, and hurriedly said: "Liu Gong, Lin Gong, what is this doing?"

Liu Chengyun lowered his bald head and said, "King, villain...... The villain has eyes and doesn't know Mount Tai, and the class makes the king laugh when he gets an axe! ”

"King, the villain is convinced!" Lin Zhaocai said it more bluntly.

Yang Fuyun stood stunned and chose to stay aside and not speak.

A sneer appeared at the corner of Yan Zheng's mouth, thinking that this was the culture of traditional craftsmen.

At the beginning, Wang Quan and Yang Fuyun were also shocked and convinced, so they did things honestly, honestly learned and exchanged experiences.

If they are not shocked, it is estimated that they will still be in line with the psychology of doing things and hiding their hands, and regard some experience and skills as the foundation of their lives.

Therefore, there is a very oppressive clause for ancient craftsmen to accept apprentices, that is, the apprentices have to work for the master for three years in vain.

After three years, you can learn a hand, as for the master's true ability, don't think about learning the hand in the years before the master died!

To a certain extent, this actually limits the progress of technology.

And Liu Chengyun and Lin Zhaocai's reaction was clearly intimidated by Dongfan's semi-standardized concept.

Yan Zheng smiled kindly and said, "Get up, what are you afraid of?" In the matter of shipbuilding, Dongfan really has no experience, but if it is hard to build, it can be figured out. ”

"Yes! Be! Be! These days, we have seen the craftsmanship of Dongfan! Liu Chengyun thought to himself, there must be a lot of insiders in this Dongfan, and while he was afraid, he always felt that Yan Zheng was tempting.

Lin Zhaocai also said: "King, in the matter of shipbuilding, I Lin Zhaocai will definitely tell all those things that I know...... Those students! I just want those students to be able to write these skills of mine into those booklets. ”

Yan Zheng leaned back in his chair and smiled and said, "Okay, don't kneel."

The two hesitated for a moment, and then slowly stood up.

"I heard that shipbuilding requires a dock?" Yan Zheng asked.

Liu Chengyun said busily: "The dock has a dry dock and a wet dock, which is evolved from the ship pit, and the general dry dock is used more, on the tidal coast, the use of the rise and fall of the water level to lift the ship, that is, at high tide, the ship will be introduced into a "ship pit" surrounded by an earthen embankment on three sides, and the ship will be located on the preset pier at low tide, and then use the fence to close the gap for repair work, when the ship is out of the pit, the fence will be removed, and the pit will be out of the pit at high tide. ”

"In that case, the dockyard is indispensable!" Yan Zheng wrinkled his eyebrows and asked, "Then if you build that brig, how big a dock will you need?"

"This ......" Liu Chengyun thought about it and said: "That ship is afraid that there are more than 800 materials, and the dock is ......."

"Just use the rack! For such a large ship, it is convenient to get a frame directly and place it on the frame to build, and it can avoid the inability to operate when the dock is flooded! Lin Zhaocai said suddenly.

Liu Chengyun retorted: "Frame, then how to get into the water?" Such a big ship? ”

Lin Zhaocai replied: "The mud is all over the beachhead, just use a rope to pull it!"

Liu Chengyun thought for a while and asked, "Have you ever seen this method?"

"I have seen, when I was young, I accompanied my master and went to work in an unbuilt shipyard, and the master in it built a lot of ships according to this method!"

Liu Chengyun fell silent, looked at Yan Zheng, and found that he was listening with interest.

"Since the boat rack is so convenient, okay, let's try it first!" Yan Zheng clapped his head.

Lin Zhaocai hurriedly said: "The king only needs to prepare some hardwood, and by the way, find a piece of flat land along the coast, and smash it tightly after leveling it out, presumably he can build this boat!"

Yan Zheng nodded, thinking that this time these two people should not hide their secrets.

The craftsmen sent by Zhang He under their leadership, together with some of the steel mill workers, could explore the iron-ribbed wood-hulled sailboat.

"Okay, I will appoint Lin Zhaocai, Liu Chengyun, Yang Fuyun, the three of you are the chief engineers of shipbuilding, cooperate with colleagues in the First Iron and Steel Plant, negotiate a plan, and when the plan report comes out, it will be sent to me for approval, as long as I pass here, you can go to shipbuilding!"

"King, why do you have to wait for the discussion of the First Iron and Steel Plant?" Yang Fuyun seized the opportunity to ask.

Yan Zheng said with a smile: "The wooden ribs are too expensive to consume good wood, and the keel also lacks good giant wood, so simply replace it with steel!"

"Use iron as a structure to build ships?" Liu Chengyun was dumbfounded.

Lin Zhaocai was also stunned, this is a complete anti-experience.

Yan Zheng said complacently: "With my Dongfan's proficiency in steel technology, a mere keel longitudinal iron rib is not a problem at all!" Don't worry, you can build with peace of mind, the ship can't be sunk! ”

The three of them hesitated for a moment, but finally took the order in unison.
