Several boatmen were indeed experienced. They used more than an hour to estimate the required materials and labor based on the ship model and drawings. Zhao Bing took it over and saw it and looked at it. He did not expect that a wooden boat without any mechanical and electrical facilities would also require more than a hundred processes. But now the arrow was on the string, and Zhao Bing had no way out. He could only look at it and ask, and the old men also thought that Zhao Bing was a child. Moreover, it was related to his life and explained in detail to the best of his ability.

Zhao Bing was originally engaged in ship design and manufacturing. Although the materials and crafts used in shipbuilding in ancient and modern times are very different, the principles are the same after all, and it can be considered a lesson based on their explanation. He has a great river in his heart, and what he sees is just a ravine, which sounds natural and does not make any effort, but it is also quite rewarding, which makes him understand some issues that he did not understand in his previous life and even has controversial in the academic world. This is really better than reading for ten years after listening to your words. He thought that if he could return to his previous life, he could become a world-class ancient ship expert with these things. After all, the 'descendants' were all speculated based on archaeological excavation and the records in historical books. He not only saw it, but also participated in the manufacturing...

Selecting wood is the first step in building a ship, and Zhao Bing found that the ancients were really smart and luxurious. The cleverness lies in the fact that they have already realized the differences in the construction and use of northern and southern wood in sea ships. Southern wood is suitable for sea water, northern wood is not suitable for sea water, and sea water alkaline is harmful to the properties of wood, so northern ship wood cannot last long when entering the sea. We know that according to the different stress-bearing parts of the ship, the keel is Mass Pine, the bow of the keel is camphor wood, the mast seat, and the rudder seat is nanmu; the outer panel is fir, and the bulkhead is cone wood, and the important parts are such as mast seat, rudder seat, and the bow of the keel is hard nanmu and camphor wood.

Zhao Bing was sweating coldly as he heard this. Nanmu, camphor, and ironwood were almost as expensive as gold in his previous life. Some were priced at gram. Not to mention the whole ship, even if the interior decoration was used, everyone would be envious of it. It was not sticking wood on the ship, but gold on it. It was fortunate that it was in the Song Dynasty, and the primeval forest in Qiongzhou had not been destroyed yet. It didn’t cost money to cut it away. Otherwise, he would have to change several ships and the general’s mansion to go bankrupt!

After buying the wood, it is not available now. It must be placed in the sun and observed while drying. Only when the wood is dry and wet can it start to detach the wood. The so-called detachment means to remove various shapes of squares and wooden boards for shipbuilding from the wood. The skeletons are used for ship skeletons, wooden boards on the edges and bottoms of the ship. A ship requires dozens of different squares and wooden boards, and most of these materials are arc-shaped. How to make the best use of wood is a test of the talent of craftsmen. Zhao Bing doesn't have to worry about this. I think these masters must know cost control.

Once the wood is ready, the shipbuilding can be officially started. After the keel is erected, the boatmen install cross beams and cross firewood on the keel, and then fix the large pounds on the side of the hull. After the skeleton is set up, the ship board is then installed to form a complete hull. This process is simple, but in fact there is a lot of work. The square material and the square material should be connected by trapezoidal tenons, holes should be dug between the plates and fixed with iron nails.

The last process is to apply ash and paint. This is a job that seems easy but has high skills requirements. According to the climate in Hainan, Linga people like to use tung oil, lime and coconut shreds to make mortar in different proportions, and apply the mortar into the seams. It is mainly used to seal nail holes and smaller pores to block iron nails to prevent rusting and corrosion of the nails. When the mortar in the gap is air-dry, use tung oil for the first time and use paint for the second time to seal the ship. The boat can enter the water.

After entering the water to confirm that the hull is safe, you can start installing internal facilities and weapons. Then after about ten days of trial sailing, you can deliver it to use. Zhao Bing thought that this process is much more rough than modern ones. Now, a new ship's trial sailing not only needs to be inspected by various sea conditions, but also needs to be inspected under different climatic conditions. In this process, various equipment and weapons on the ship must be tested. Only after everything is OK can it be finalized and produced, and the time will last for several months or even years...

"Dear masters, how much error can you have in your estimated working hours?" Zhao Bing asked after finishing his "study" and said with a little bow. This is not because he respects technical talents, but because he was scared by the old men who kneeled down and kowtowed at any time, and was worried that they would return the gift again.

"Your Highness, the name of a great craftsman is not dared to bear it. Just call him a low name." Sure enough, a few people replied with gratitude again.

"A few masters are all leaders in the South China Sea ship industry. There is nothing I can't afford to be. Don't be so polite again from now on, otherwise I will be angry!" Zhao Bing certainly wouldn't have such an intention. Wouldn't that behaved like to look down on himself in his previous life? He pretended to be angry.

"Your Highness, I'm not polite!" Boss Li said this but gave a great gift and said, "Your Highness, although time is rushed, we estimate that the difference is almost the same. Even if there is a major mistake, it will only take one day."

"Well, since that's the case, I have an idea to ask some masters to study it out to see if the construction period can be advanced." Zhao Bing tried his best to make himself mature so that these old men would not treat themselves as children who don't understand anything. He coughed lightly and nodded seriously.

"I wish to listen to Your Highness's wonderful method!" several old men said in unison.

"I think so..." Zhao Bing saw that he couldn't hide his smile on his face and knew that he had failed in the installation. He could only shock them with 'real talent and real knowledge'. "I think we can only put into use three docks now, so we can only transform one ship and then transform the next one. Therefore, even if there are too many people, it is difficult to unfold and cannot be constructed at the same time, which will extend the construction period, right?"

"What Your Highness said is that because of the limitations of the dock, you cannot perform your skills. Even if you keep working day and night, it is difficult to complete within the time limit!" Boss Li said, and the others nodded to show that it was exactly this.
Chapter completed!
