After dinner, Liu Bao handed over food and grass several times under the pressure of his wife.
Then there was no time to look at the small iron boat.
After some exchanges, we went to bed early.
Early the next morning, the neighbor's big rooster started crowing at dawn.
Liu Bao was startled, opened his eyes suddenly, and immediately remembered that the small iron boat was still soaking in the water!
I finally worked it out yesterday, but I forgot about it after playing poker!
Liu Bao got up as soon as the wheel rolled over and hurried to the bathroom to fish for the boat.
He was afraid that the boat would sink and become rusty after being soaked in water for a long time.
Finally, when we arrived at the bathroom, we opened the door and saw the boat floating steadily on the bathtub.
"How come this... didn't sink? Is the cabin not full of water?" Liu Bao said to himself in a daze.
Yesterday, the hull and planks were connected with rivets, and there was no time to polish the seams.
It was just made casually to verify that the iron ship could float on the water.
He originally thought that the small iron boat would sink in an hour or two.
Unexpectedly, it has been all night, and the small iron boat is still floating firmly on the water.
Liu Bao picked up the small iron boat and took a look at it, and immediately stood on the spot.
The cabin is actually dry!
Not a drop of water!
Even the water stains that accumulated a few times when the sink was flooded last night have dried up!
It doesn’t look like water has entered the inner wall at all!
"How could this be? Are there no gaps in the hull? No! Are the rivets so tight?"
Liu Bao frowned and checked the bottom of the boat with doubt.
You can't see any gaps with the naked eye, and you can't even insert a razor blade into it.
Liu Bao was a master carpenter, so of course he often used rivets.
After the wood is pulled with rivets, it is very strong and can be filled with water.
Because the wood is soft, the fit will be very tight.
In his impression, steel should not achieve this kind of sealing effect.
After all, steel is much harder than wood, as hard as iron.
Liu Bao thought about it for a while, then put the boat into the water and looked at it carefully.
After being placed on the water several times, there is still no water seepage at the bottom of the boat, and the sealing performance of the hull has been confirmed.
As Liu Bao watched, a gleam suddenly flashed in his eyes.
"Thin rivets can rivet thin ship plates. Can larger rivets also rivet thicker ship plates?"
"Can rivets really rivet a ship's hull as densely as wood?"
Liu Bao muttered to himself, and actually said that he was a little surprised.
"If this is the case, then shipbuilding..."
Liu Bao suddenly felt excited and hurriedly hugged the boat and ran out.
"Ms. sir! Where are you going in such a hurry!" Liu Bao's wife shouted.
Liu Bao just went to the bathroom in a hurry, and his wife didn't know what he was doing.
As soon as he got dressed and came out, he saw Liu Bao running out of the bathroom holding a small iron boat.
"Go find the prince!" Liu Bao replied loudly, with some excitement in his words.
"Hey, hey, hey! Don't go! My husband, you have to go to the prince's place to change your clothes!" Liu Bao's wife hurriedly stopped him and said.
Liu Bao was stunned. When he lowered his head, he realized that he was wearing pajamas now. Those big pants and vest were so big that he would become a scene in Jiangzhou if he ran on the street!
…
"duang!duang!duang!"
Upstairs in the residence, there was a knock on the door of Song Yang's house.
Song Yang is frying eggs right now.
Every morning I fry three eggs, give them to Tong Qian and Shen Xiaowan, and eat the soft ones myself.
The steamed buns can only be eaten with some egg dregs. It's not Song Yang who is digging, but Tong Qian who heard that children can't eat fried eggs...
"Xiaoqian, open the door and see who is coming early in the morning."
Song Yang said hello and the eggs would be ready soon, which would make people unable to leave.
Tong Qian came out of the children's room, held the steamed bun playing with the rattle, and opened the door.
It's not like there are no servants in Song Yang's family.
It's just that the servants are almost all part-time workers, and the old woman who usually cleans doesn't come until late in the day.
They didn't stay at Song Yang's place at night.
In Song Yang's words, we have a big house but we don't have a room for servants, so why let them live here?
So it was early in the morning and there was no servant at home, so the hostess had to open the door.
As a good young man who has received nine years of compulsory education, he has never been very accepting of the behavior of servants.
Moreover, after the natural disaster, in order to maximize the efficiency of personnel utilization, the household registration system has been cancelled, and all servants automatically redeem themselves.
There is no longer a relationship with the original owner to control personal freedom.
Officials of all sizes in Jiangzhou also followed the same example. They did not always keep servants at home, they were all similar to hired workers.
"The princess is a thousand years old, I wish you a happy birthday."
"My little prince is a thousand years old!"
The door opened and it turned out to be Liu Bao.
When Liu Bao saw Tong Qian opening the door, he immediately greeted her politely.
It was not too late to say hello to the steamed buns with a smile.
"Xiaobao, come and talk to the prince," Tong Qian said with a smile.
Tong Qian is a few years older than Liu Bao. Liu Bao always treats the female members of the Song Yang family respectfully every time he sees them.
This guy is also very down-to-earth and does a good job.
Song Yang often praised Liu Bao for his work and conduct at home.
Song Yang heard the sound and knew Liu Bao was coming. He shoveled out the freshly fried eggs before coming out of the kitchen.
As I walked out, I took off my apron. When I arrived in the living room, I saw Liu Bao changing his shoes.
"Why are you here so early in the morning?"
"Huh? Is this... the boat ready?"
Song Yang wiped his hands with his apron, threw it aside, looked up and saw the boat in Liu Bao's hand, thinking that he was here to show off his achievements in the small iron boat.
"Your Majesty! Look at this little boat. It was soaked in the bathtub all night yesterday. There is no water at all in the cabin! It didn't take in any water, let alone sink!"
Liu Bao was a little excited and handed the small iron boat to Song Yang.
Song Yang took the small iron boat and took a look inside the cabin.
Sure enough, the cabin was dry.
When he turned the bottom of the boat over and looked at the seams, Song Yang was also stunned.
"You... you used rivets to rivet it on? It looks very strong!"
"Yes, Your Majesty. When the students went back yesterday, they first used iron pieces to fold the bottom of the boat. But after a while, the gap got bigger and the boat floated and sank."
"Then the student just thought about it and riveted it with a rivet. He thought it would be enough to play with it for a while and verify the principle of buoyancy."
"But after dinner, I just... ahem... forgot that it was still soaking in the water."
"When I woke up in the morning, I saw that there was no water in the cabin."
Liu Bao told how he made the boat yesterday.
Song Yang frowned and studied the boat for a while, then hugged the boat and said to Liu Bao: "Come! Come! Come! Let's go try it!"
With that said, he carried the boat into the bathroom.
There was a large bathtub in the bathroom, and Song Yang immediately filled it with water.
While waiting for the water to be drained, Tong Qian, Shen Xiaowan, and Mantou were all staring at Song Yang and Liu Bao at the bathroom door.
Seven months into her pregnancy, Shen Xiaowan's belly grew bigger again, even bigger than Tong Qian's this month.
Lu Jimin said they were probably twins.
When I first heard the news, I almost laughed Song Yang to death.
Shen Xiaowan has already become a blockbuster without even mentioning anything. She hasn't been pregnant for several years, and now she has two children.
Just now, she was lying on the bed doing some of the fetal protection movements that Song Yang taught her.
When I heard someone coming to the living room, I put on my clothes and went out to take a look. I saw Song Yang playing in the water and playing with a boat.
Among the three people watching the fun, the one who was most excited was the steamed buns.
This kid pointed at the boat, obviously wanting to play.
"This is a treasure, I can't give it to you!" Song Yang shook the boat and smiled.
Steamed Bun grinned and started crying, crying heartbrokenly.
After howling fiercely, Tong Qian hurriedly picked up the steamed bun and said, "Here it is! Here it is! Stop crying! I'll give it to you when your father is done with it!"
Steamed Bun turned his head to look at Tong Qian, then looked at Song Yang with questioning eyes.
He seemed to be asking if what my mother just said counted.
Song Yang had no choice but to say: "You are amazing! I'll give it to you soon!"
Don't look at the little man, he understood it immediately and stopped crying immediately.
Not only that, he also grinned: "Giggle!"
I have to say that this kid is very good at fake crying...
After a while, the water in the bathtub was filled, and Song Yang put the boat on the water.
The boat floated really smoothly.
I pushed it with my hand and the boat moved slightly.
I picked it up again and looked at it. Sure enough, there was no leakage.
Put it into the water again.
Song Yang put a little more force on his hands and pressed down on the hull of the ship.
Press it all the way to the edge of the horizontal line, pause for a while, and then pick it up to check again.
"There is still no water leakage! Can this... riveted boat work?" Song Yang said to himself in surprise.
"Your Majesty! Maybe this can really work! When the students discovered this in the morning, they thought that big ships might also be riveted!" Liu Bao also said at the side.
"Riveting big ships!" Song Yang's eyes lit up, as if he had found a new path.
"Whoa whoa whoa!"
Song Yang was so excited just now that he pushed the boat into the water. When Mantou saw that his things had sunk, he immediately screamed.
Song Yang picked up the boat, looked at Liu Bao and said, "You go back first. I want to think about this principle."
"Yes! Then the student will leave first!" Liu Bao nodded.
"Hey, has Xiaobao eaten? Your Majesty just made omelettes." Tong Qian asked.
"Yeah. Eat. Thank you Princess for your kindness. The students will leave first."
…
As soon as Liu Bao left, Song Yang immediately carried the small iron boat to the study.
The steamed buns screamed again, fearing that Song Yang would regret not giving him the small iron boat.
Tong Qian had no choice but to follow behind with the steamed bun in her arms.
After entering the study room, the steamed buns immediately stopped making trouble.
As long as he can watch the small iron boat and not be hidden by Song Yang, he won't make trouble...
Song Yang touched the bun's head, then closed his eyes and leaned on the chair to flip through the encyclopedia.
First find the metal category, there are hundreds of thousands of pages...
The second step is industrial metals and industrial technology, hundreds of thousands of pages...
Looking for metal joining technology, tens of thousands of pages...
Then find Metal Riveting, thousands of pages…
After searching for a while in Metal Riveting, I finally saw the sub-category "Hull Riveting" with four large characters on a certain page of Riveting!
A small sub-item can contain hundreds or dozens of pages of content!
"Holy crap! It really works!" Song Yang was speechless.
If I had known that riveting could be done, I would have bothered to study welding dry chicken feathers!
Just rivet it directly!
With the current level of technology, there is absolutely no problem in riveting hulls.
Those steam engines, steam hammers, and internal combustion engines all use riveting technology for their components.
Song Yang clicked on the project of hull riveting.
I actually saw the complete riveting shipbuilding process in the extended content.
What left Song Yang speechless the most was that in the hull riveting project, the three ships used as examples were all Song Yang had heard of.
"Titanic", "Olmabaik", "Britanic".
Good guy, the three sister ships all ended badly...
Of course, not to mention these three chestnut ships, riveting is definitely feasible.
Continue to click on the detailed classification of "Riveting Ship Construction Technology".
Three big steps on the catalog:
Slipway bulk.
Dock Outfitting.
Whole ship painting.
Song Yang looked in one by one and was so angry that he wanted to curse!
"Oh my God! I have been working hard on electric welding and shipbuilding for more than a year, but it turns out that I can do it by riveting?"
What kind of golden finger is this?
Even if there is no system prompt, can you add a search function for me?
Song Yang was speechless.
When people get a golden finger, they basically have to have something less.
You can do it yourself, encyclopedia!
Hundreds of millions of pages of content, without search or guidance, just relying on classification retrieval, it would take hundreds of lifetimes to search!
It wasn't until he saw a sentence on the last page of Riveting Shipbuilding that he felt a little better.
"Riveting has low production efficiency, high labor intensity and high noise, and has been replaced by welding in steel ship construction."
"It turns out that I am still a little ahead of my time!" Song Yang was very happy and Ah Q comforted himself.
…
After finding the complete riveting shipbuilding technology, Song Yang hurriedly ate egg pancakes and drank a sip of soy milk before going out.
Just as Song Yang was about to put on his shoes, the steamed bun started to scream again.
Because he saw Song Yang holding the boat and leaving.
Song Yang looked back at his eldest son, put a smile on his face, put the small iron boat on the ground and said:
"Smash it! It's not that dad won't give it to you. Even though this thing is small, it's made of iron! If you can handle it, I'll give it to you!"
Steamed Bun broke away from Tong Qian's arms and ran to the small iron boat.
"Don't be brave, steamed buns, or you may get hit on your feet." Shen Xiaowan reminded with a smile.
Mantou looked at his aunt, his eyes rolling, and pointed at the small iron boat Aba Aba, indicating that he could do it.
"Yeah, you can do it. Go and try it." Tong Qian, a mother, waved her hand and said.
This kid is walking more and more slippery now, but he still doesn't speak very fluently.
In addition to the cries of "Aba Aba", words such as "eat", "hungry", "full" and "greedy" will occasionally pop up, making it like a starving ghost reincarnated, just knowing how to eat!
After the steamed buns passed by, Tong Qian and Shen Xiaowan also looked at the steamed buns with great interest.
When he reached the boat, Mantou looked back at his mother and aunt, and then reached for the small iron boat.
This small boat must have weighed five or six pounds, and Mantou grabbed the bow of the boat hard.
The little kid didn't expect that this little thing was so heavy, and he couldn't stand firmly, so...he fell flat on his butt.
"Hahaha!"
"Giggle!"
The three adults laughed together.
I thought that Steamed Bun would cry and make a fuss, but I didn't expect that Steamed Bun was okay. He got up and went to tow the small iron boat again.
This time he knew that the small iron boat was heavy, so he pulled it and realized that he couldn't pick it up.
But it doesn't matter if you can't pick it up, you can drag it along.
I saw the steamed bun dragging the small iron boat and moving it bit by bit.
The boy spent a long time and finally dragged the small iron boat to Tong Qian's feet.
Then he looked at the boat and giggled.
He felt that the boat belonged to him from this moment on.
"Okay! Here you go! I didn't expect you to have some abilities! Well... there's only one chance in a billion that your father will be able to come!"
Song Yang saw that Mantou was so happy and didn't want to offend him anymore, so he gave the boat directly to Mantou.
If we take away the boat now, the scream of the steamed buns can lift the roof of the house directly.
Most people can't afford to offend this little ancestor, even the king of Jiangzhou is talking about it for nothing.
After leaving home, Song Yang returned to the small courtyard where he originally lived.
This place has been connected with the laboratory at the back and transformed into Song Yang's personal research and development experimental center.
The scientific research center is in the east of the city, which is much closer. Song Yang was anxious to build another iron boat, so he came directly here.
After asking two guards to help and rummaging through some materials and tools from the warehouse, Song Yang started tinkering with the iron ship.
He used larger and thicker iron plates, and the rivets were also larger.
The small steam stamping machine here in Song Yang is smaller than the one at Liu Bao's house.
It can't press such a thick iron plate.
But that's okay!
We, the king of Jiangzhou, have the power, and we can work miracles with great force!
"Hey!"
Song Yang shouted low, pressed with his hand, and used the force of the bending machine to directly bend the nearly one centimeter thick iron plate.
"Great work, Your Majesty!" The two guards who attacked looked surprised.
The prince shows off his skills like this from time to time, and they can only envy him.
"Come on, come on. I have to bend this way."
Song Yang directed the two men to adjust the direction of the iron plate, and then repeated the same trick to press this side as well.
Someone helped, and Song Yang worked very quickly. In one morning, the hull of the boat was folded into shape.
If we had just folded the hull, we could have done it a long time ago.
Just now, Song Yang folded the hull and found that there was no place to place rivets, so he disassembled it and made improvements. Now the joints inside the hull are bent.
The bends of the two iron plates fit together and can be fixed with rivets.
After folding the hull parts, Song Yang took two helpers to polish the fitting parts.
Then use pressure clamps to hold it in place, and then use a steam drill to drill a few rivet holes.
Song Yang directly used the largest rivets available in Jiangzhou.
This kind of rivet is used to make the edging iron frame outside the steam engine.
Although it is a bit small when placed on the hull of a ship, it is already the largest rivet currently available.
At noon, during dinner, several people came.
It's almost done in the morning, and now we're drilling the holes mechanically.
Song Yang asked Liu Bao and Wang Muyue to come over, and also found a senior master from the shipyard.
Jiangzhou Shipyard has been completed and put into production. The first wooden sea-going ship is being produced. The progress is pretty good and it is expected to be launched next summer.
When the old master came, he saw the iron ship being processed.
Liu Bao came with Wang Muyue, and they both held a small iron ship model in their hands.
This one they made in the morning is smaller than the one Liu Bao made yesterday.
It's just a model.
Song Yang explained the principle of buoyancy to the old master and experimented with a small boat.
The old master was also surprised.
"Can such a big iron ship really float?"
Although the old master saw that Liu Bao's model boat could float, the one made by Song Yang was more than three meters long.
It is just a ship bottom without any parts, just for testing the buoyancy of the iron ship and the effect of riveting.
Facing the old master's question, Song Yang said confidently:
"Yes! After the rivets are drilled this afternoon, we will test the assembly!"
