Chapter 1128 Reverse Engineering

    Of course, this kind of modular production is only suitable for large-scale mass-produced ships. Currently, only a few government-owned shipyards in Ming Dynasty are using it: Longjiang Factory, Qingjiang Factory, and Suzhou Factory.

    In the private shipyards in Fujian and Guangdong, each ship is still laid out on site by the master master, so every ship built in the south is different, and most of them are crooked and cracked.

    Then Mr. Zhao went to the sailmaking workshop and watched the process of the sailmakers weaving bamboo strips into sails.  I saw that every time they weaved a piece of sail, they would insert a piece of canopy bamboo with a canopy rein as the backbone, so that it could be folded piece by piece and the sail could be raised close to the mast.

    In terms of performance, this bamboo strip sail is of course not as good as a canvas sail, but for use on transport ships and merchant ships, this affordable and durable sail is enough.

    ¡°Then in the oyster shell making workshop, he saw the workers crushing the collected oyster shells and then sending them to the kiln to burn them into lime.  The calcium carbonate content of oyster shell ash is more than 90%. The lime sintered at high temperature is most suitable for blending tung oil to form calcium tung oil with excellent water resistance.

    Then mix it with hemp silk to make putty twist material, which is used to fill the seams of ship hulls and the holes of iron nails.  By only brushing oil once a year, you don't have to worry about water leaks in the hull, and it can also prevent nails from rusting.

    Zhao Hao asked Blanco, the chief shipwright on the Oriental Beauty, that European shipyards caulked seams with oiled hemp fibers and then applied a layer of tar boiled from asphalt to waterproof them.

    ¡°Tar is not only toxic, but its waterproofing effect is not as good as Ming Dynasty¡¯s putty twist When Zhao Hao returned from the Oriental Princess, he encountered water seepage in the hull. Fortunately, it was dealt with in time, so the tragedy was avoided.

    And the entire punishment fleet has been at sea for two months, and there has been almost no leakage.  Well, this is also related to the fact that the fleet is all new ships

    However, even if the old ship leaks, you are not afraid. Daming¡¯s unique watertight cabin design can greatly improve the ship¡¯s survivability.

    Zhao Hao was in the iron workshop again and saw the bare-chested blacksmith masters sweating profusely in the winter making iron nails for ships.

    Chinese-style ships have been using iron nails to fix ship planks since the Warring States Period. By the Tang and Song Dynasties, the technology was fully mature.  Zhao Hao saw that in the workshop, there were seven or eight types of finished iron nails.  There are shovel nails, square nails, curium nails, date stone nails, climbing nails, flat head nails obviously each has its own purpose.

    At this time, there was not a single iron nail to be seen on the European ships, only wooden nails were used.  Although wooden nails are better than wooden nails, for example, they will not affect the accuracy of the compass and will not rust.

    However, just drilling tens of thousands of wooden nails into the board one by one will take dozens of times more man-hours than iron nails.  This alone is enough to make a judgment.  Europe currently does not use iron nails, mainly because they are not good at smelting iron and wrought iron is too expensive to use.

    Therefore, Ming Dynasty¡¯s shipbuilding technology is still ahead of Europe in many aspects

    After visiting the workshops one by one, Mr. Zhao¡¯s biggest feeling was.  Boats are really not that easy to build!

    It¡¯s no wonder that the shipbuilding level of Li Dynasty and Japan cannot improve, because this is a complex system engineering.  If you want to improve your shipbuilding level, there are too many areas where you need to make up for your mistakes.  This cannot be done by hiring a few shipwrights, the entire system must be moved there.

    ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? Go ahead and dream!

    It was already noon after taking a walk around the various workshops.  Everyone followed Young Master Zhao to have lunch in the shipyard's third canteen Secretary Ma had said hello in advance that Young Master was pressed for time and would not hold a banquet, so he could just use some in the staff cafeteria.  I also took the opportunity to inspect the workers¡¯ meals.

    There are rows of long tables in the huge three canteens of the shipyard, which can accommodate two thousand people to dine at the same time.  There are two more canteens like this in the shipyard.  Otherwise, it would be impossible to feed the entire factory, which has more than 5,000 mouths of craftsmen, apprentices, security guards, and civilians.

    The cafeteria was buzzing with people. After Mr. Zhao and his entourage came in, their voices suddenly became much lower.

    "Eat your food." Ma Hu quickly waved his hand, and the workers continued to eat.

    The shipyard adopts a meal supplement system, 600 yuan per person per month, which is paid together with wages.

    There are not many dishes in the cafeteria, but they are very cheap.  Vegan dishes such as winter melon and fried radish cost one penny; leeks, eggs, and pork with garlic sprouts cost two cents; a chicken leg cost three cents, and a portion of fatty pork also cost three cents; rice cost one cent and three taels, and a large steamed bun cost one cent.  Normally, 20 cents for three meals a day will satisfy you.  Of course, if you have a big appetite, you will have to pay more.

    Zhao Hao used seven cents to buy two meat dishes and one vegetarian dish and a portion of rice. He randomly found an empty seat and sat down, chatting awkwardly with a few workers nearby.  In the three months since he went to sea, Mr. Zhao finally learned to put down his dignity, go deep into the grassroots, and greet the masses.

    But it is impossible to mingle with the masses. After all, this is a very high-level society.He glanced at Yang Fan and said, "If my brother can join us, we should be able to build the model in a few months."

    "Model ship?" Zhao Hao's eyes lit up. He likes to play with model ships the most.

    "Yes." Yang Fan nodded and said: "The method passed down from our ancestors. The first step in imitating a ship is to make a reduced ship model. Although the ship model looks like a children's toy, it has all the parts that should be on a big ship.  , and the internal and external structures are exactly the same, but they are all a lot smaller.¡±

    "Yeah." Zhao Hao didn't feel offended at all and still nodded enthusiastically.  "Shrink it proportionally."

    "By building a ship model, we can clearly understand the parts, structure, and construction sequence of the ship. So as long as we can build a ship model, we will have a clear idea of ??how to build the ship." Yang Fan added  : ¡°And it can also replace a real ship to test the performance and flaws of the ship type.¡±

    ¡°Then build it quickly!¡± What Zhao Hao was most afraid of hearing was ¡®it can¡¯t be built¡¯. Now that he heard that there was a way, his heart suddenly dropped.  (Remember the website address: www.hlnovel.com
