In fact, this kind of slipway is also what Zhu Linmiao has seen from the materials of later generations. It was not until the late Qing Dynasty that such slipways appeared in Guangdong, Fujian, and other places, while Europeans began to use similar techniques at the end of the 16th century.

However, due to the appearance of Zhu Linmiao, the gap between Eastern and Western shipbuilding technology was shortened by more than 100 years.

He also plans to use stone powder, or cement, to pave the floor of several of the shipyard's main work areas, as well as to connect the roads between them.

Due to the large area of the shipyard, it can only be opened in the open last night. Although the existing sandy land of the shipyard has been tamped to a certain extent, as long as it rains, it will have to stop work for at least seven or eight days.

However, if there is a concrete floor, it can be restarted in at most half a day.

Although the price of fairy stone powder is extremely high, this thing is actually made of clay and limestone, and the cost is not high. In order to create a fighting Daming Water Division as soon as possible, Zhu Linmiao will never be reluctant to do this.

As for the tools for forging, drilling, grinding, cutting, etc., he was sure to give the shipwrights a complete set of updates.

In addition to these "conventional" upgrades, he also has a "big killer" in his hand that far exceeds this era, that is, the gantry crane that is necessary for shipbuilding in later generations.

Of course, limited by the existing conditions, there must be a gap between the degree to which he can do it and that of later generations. Due to the lack of proper forging technology, the frame is now only made of wood, which has a much worse load-bearing capacity and dead weight than a steel frame.

Moreover, the lifting equipment can only rely on the hand-cranked winch and pulley, and the animal winch is used at most, but it should not be a big problem to pull up about a ton of materials.

At the same time, the gantry crane can only use animal power to move back and forth, but Zhu Linmiao designed the gantry crane to be built on a wooden track, and it should not be too difficult to move.

And once this thing is put into use, it can simply double the efficiency of shipbuilding!

The gantry crane is actually a huge "N" shaped crane that straddles the hull of the waiting ship. This is when a large component needs to be fixed somewhere in the hull of a ship during the shipbuilding process.

In the 17th century, the traditional way of building a ship was to build a pyramid-shaped wooden frame where large components were to be installed. Then hundreds of people worked together to pull the heavy parts to the top of the wooden frame, and then slowly moved them to the side of the hull, where other craftsmen stepped forward to fix them.

When this one part is installed, the wooden frame loses its function and has to be dismantled again and taken to the next place for installation.

This process takes a lot of time just to disassemble and assemble the wooden frame, not to mention the process of lifting the parts and moving them.

But gantry cranes can solve these problems very well.

The whole gantry crane is moved back and forth along the slide rail, the hull parts that need to be installed are lifted, and the gantry crane is dragged by livestock to move to the top of the hull, slowly lowered, and the craftsman fixes the parts. The whole process is at least several times faster than the traditional way.

Moreover, the gantry crane can be reused, which saves a lot of time for disassembling and assembling wooden frames.

Actually, this thing is not that complicated to put it bluntly, but the technical aspect is like this, often a little burst of inspiration can bring huge improvements.

However, this innovation is unthinkable, and you can't think of it. It often takes hundreds of years for human beings to gain inspiration and make breakthroughs. It's just that Zhu Linmiao brought these inspirations to Daming in advance.

He was thinking about the technical transformation of the shipyard when he saw Zheng Chenggong coming with a whip, turned over and dismounted when he approached, raised his hand and saluted, "Your Highness, more than 2,000 shipwrights in this vicinity have all been gathered." ”

These boatwrights are actually villagers from several nearby villages, who have lived by the sea for generations. This time, Zheng Zhilong fell, and all villages were afraid that they would also be involved in a major treason case, so they fled everywhere.

Zheng Chenggong summoned some old acquaintances from Nan'an, and it took a lot of effort to get them together again.

Zhu Linmiao nodded and said, "Can they return to work in the near future?" ”

"Back to His Royal Highness, several clan elders have spoken, as long as the court orders it, they can start work immediately." Zheng Chenggong then frowned again, "It's just that the wood hasn't landed yet." ”

Zhu Linmiao pointed to the hills in the distance, "There are towering ancient trees all along the way, and people will cut them down immediately." "Fujian has been a shipbuilding mecca since ancient times, and a large part of the reason is that it is rich in forest resources, and a large number of hundred-year-old or even thousand-year-old giant trees are available for people to choose. In the era when wooden sailing ships dominated the seas, there was an unrivalled advantage in shipbuilding.

Without waiting for Zheng Chenggong to speak, Pang Zhu on the side arched his hand and said: "Your Highness, the moisture of the wood from the first cut is too heavy, and it will quickly become out of shape and crack if it is directly used on the ship."

"Therefore, the new wood has to be dried in the shade for at least a few months, and the large material even has to be dried for many years......"

When Zhu Linmiao heard this, he felt that his head was big for a while, and what he lacked most now was time, so he frowned and said, "Where can I buy wood?" ”

"Your Highness, ordinary materials are easy to buy. But if you want to build a large ship, the giant wood needed for this keel and girder is not easy to find. ”

Zhu Linmiao said helplessly: "Send people to find it." The price is more than 50% higher and I will buy it. ”

"The subordinate obeys."

Zhu Linmiao said to Zheng Chenggong again: "Da Mu, bring all the craftsmen." There is still a lot to be done before the timber arrives. ”

"Yes!"

The next day, in the open space in front of the shipyard, more than 2,000 craftsmen from nearby villages gathered.

Zhu Linmiao originally wanted to announce the shipyard's policy in public, but the sound of the waves on the side continued, and people who were far away couldn't hear it at all.

In desperation, he had to let the village stewards turn to the hut where they did carpentry work.

At that moment, more than 100 people walked into the shed, and the local magistrate gave Zhu Linmiao a general introduction. More than a dozen of these people are village elders, and the others are the main technical leaders in shipbuilding.

Only then did Zhu Linmiao know that most of the more than 2,000 people outside were doing ordinary hard work, of which about 30% were carpenters, 10% were blacksmiths, and some rope makers and sail makers.

And the person who is actually responsible for the overall construction and the construction of key locations is the one hundred and ten people in front of him.

He opened with a clear statement: "The Helan people flaunt their might along the coast of our Ming Dynasty, which directly threatens the maritime trade of the Ming Dynasty. Now the imperial court is in urgent need of large warships to drive away foreign invaders and determine our maritime frontiers, so as to facilitate the exchange of goods between the Ming Dynasty and foreign countries. ”

The shipwrights present were all stunned, they were born, and it was the first time they had heard that the imperial court wanted to build warships on a large scale in order to facilitate trading with the Yi people.

Their hearts immediately warmed up, it was nothing for the imperial court to build warships, but listening to the meaning of His Royal Highness the Auxiliary King, the imperial court would encourage trade at sea in the future, so could this merchant ship be missing?

They are all people who rely on shipbuilding for food, and if this is the case, there will be less income in the village in the future.
