Hongwu Survival Guide

Chapter 192 The Ultimate Challenge
After observing for a while, he felt that the water was still a little slow, so Zhu Yuan said to Jin Sanhu: "Intensify the fire."

Jin Sanhu agreed, found a pair of tweezers from the side, picked out a wick and put it in the candle under the mini water tank to light it. One flame turned into two.

On the other hand, the piston transmission speed is significantly accelerated.

Zhu Yuan was very interested: "Add more."

Kim Sam-ho continued to add another wick.

The transmission and water outlet speed up again, and the water outlet of the mini water pump similar to the field water pump of later generations is like a water arrow.

After dozens of breaths like this, the water mist on the piston decreases, and the transmission gradually slows down until it stops.

Signaling Jin Sanhu not to add more water, Zhu Yuan pulled a chair and sat down, saying, "The quality is very good."

There is no problem with turning so fast, I have to praise the craftsmanship of the craftsmen here.

"It's an adult's idea. The bearings are durable." Jin Sanhu said, seeing Zhu Yuan reaching out to the mini steam engine, he quickly stopped him: "My lord, be careful it's hot."

Zhu Yuan then turned to the water pump: "I'll take it apart and have a look."

Jin Sanhu stretched out his hand to help pull the small transmission belt apart, and handed over tools such as a pry knife and tweezers, and raised his hand to signal: "My lord, cut carefully, don't you come here like a small one?"

Zhu Yuan ignored it, first took off the thin leather tube, and looked at it for a while.

Both the water pump and the steam engine are embedded on a wooden base the size of a book. To ensure stability, the bottom is fastened with iron nails.

There was no intention of taking it off.

Turn to pump body.

The diameter of the runner that mainly plays the role of pumping is about one inch in diameter, and the water inlet and outlet are the thickness of chopsticks.

It can be seen that the joints between the upper and lower water inlets and outlets and the runners, as well as the shafts on both sides, have been polished, but there are still faint welding marks.

This age is welded.

In fact, even as early as the Shang and Zhou dynasties, welding techniques had already appeared. Of course, it was not electric welding, but it was not casting, but welding of different metal components.

Although the small water pump in front of him looked seamless after being welded and polished, Zhu Yuan, under the guidance of Jin Sanhu, used a crowbar to open the small thing along the pump body.

The overall bronze material is easy to pry up.

After a while, a series of smaller-sized various parts appeared in front of Zhu Yuan, mainly a short steel shaft, two miniature bearings slightly smaller than copper coins, a runner connected to the drive belt on the outside, and a shaft embedded in the shaft. Water wheel on pole.

What makes Zhu Yuan more emotional is that all of this is so small and so fine. Even, thinking about the previous operation, there is no water leakage, no overload, and there is no failure until the hot water in the small water tank is boiled dry. This can already be described as precision.

While fiddling, Zhu Yuan noticed another thing.

In the mini bearings, the balls the size of mung beans are not made of copper, but exude the luster of steel.

Pry it open again, take out the small ball and look at it, it really is a steel ball.

Seeing this, Jin Sanhu next to him took the initiative to explain: "My lord, the bronze balls are really not durable, so I replaced the small ones with iron ones."

After thinking about it for a while, Zhu Yuan understood a little, and asked, "Can it be made bigger, one or two inches in diameter?"

Jin Sanhu said: "Yes, just slow down."

"That's impossible," Zhu Yuan shook his head slightly: "If you can only make one steel ball a day, it's meaningless."

Jin Sanhu remembered the bearing workshop he had personally visited by the river, and nodded accordingly.

This kind of mung bean-sized steel ball is easy to roll, but if it is made as large as one or two inches, the level of a pigeon egg or an egg, from his craftsman's point of view, the main reason is that the size is difficult to grasp.

To put it simply, using an iron knife to turn copper balls, the cylindrical iron turning knife in Jiangbian Bearing Workshop can turn dozens of copper balls without much wear and tear. , will wear out quickly.More importantly, that kind of turning method focuses on one-time forming. If the turning tool wears out and the size deviates, if you want to carry out secondary processing on the finished product, it will be difficult to ensure the roundness of the balls, and you can only go back to the furnace for remanufacturing.

Putting this matter aside, Zhu Yuan asked some details while fiddling.

Finally, he pushed the scattered water pump aside and asked for a pen and paper. Zhu Yuan said, "Now that the water pump has been made, I will give you some challenges and try others."

As he spoke, he began to quickly draw on the white paper with a charcoal pencil.

Steam trucks, steam excavators, steam bulldozers, steam rollers, steam cranes...

After several consecutive paintings, Zhu Yuan remembered one and asked Jin Sanhu, "Do you know bamboo dragonflies?"

Jin Sanhu nodded and fiddled with his hands together: "That's right, the one that can fly?"

Zhu Yuan looked at the various materials on the tables all around: "Use wood chips, make one for me on the spot."

Jin Sanhu was about to do it, but Zhu Yuan stopped him and motioned to the other craftsmen: "You guys do it."

Immediately, Jin Sanhu returned to his side and began to explain: "Steam truck, you can know what it is by looking at the picture, and it can run without tracks. The steam excavator... is mainly the front bucket. As big as the height of our house, the kind that can shovel out hundreds of catties of soil with one shovel. Also, bulldozers, road rollers, cranes, etc. are all large machines that can build roads and houses. The picture is just one Style, my request is, as long as it can achieve a simple purpose, for example, it is for digging, it is for bulldozing, it is for compacting the road back and forth like a roller, it is for hoisting a few thousand kilograms to the A height of more than ten feet, think about it, can it be realized?"

Jin Sanhu looked at Zhu Yuan's drawing, frowned slightly and thought for a moment, then nodded and said, "My lord, if it's just a simple movement, it shouldn't be difficult."

"Then think about it more," Zhu Yuan smiled and pointed to one on the paper: "For example, this truck must be able to move forward, backward, and turn left and right. After all, the roads cannot be straight. The speed can be accelerated or slowed down, heh, this is related to your profession, probably the combination of different sizes of gears can achieve variable speed."

Jin Sanhu didn't think about it for too long this time, and said: "My lord, if it's such a small size, I'm afraid it won't work. If it's bigger, according to what your lord said, the size of the house is small, but it will take a lot of time. I'm afraid it will take a lot of time." Not cheap."

"Heh, you have plenty of time, regardless of the cost," Zhu Yuan smiled, and circled the truck again: "Actually, as long as this thing can do basic steering and movement, it is enough for the time being, and the key is to It needs to be big, the truck body should be the size of our house, and it can pull tens of thousands of catties at a time."

Jin Sanhu laughed along with him: "My lord, just think about this scene... If I can really see it in the future, this life will not be in vain."

"As long as you can do it well, you will definitely see it. After all, it is up to you to realize it. It belongs to the creator of history and can be recorded in the annals of history in the future."

Jin Sanhu bowed involuntarily, and the corners of his mouth seemed to twitch: "Master... my lord, it will be recorded in the annals of history... a humble craftsman, I dare not think about it..." He shook his head: "I dare not think about it... Mile."

The other craftsmen in the room have also been paying attention to the conversation here.

recorded in history?

They also didn't dare to think about it, nor did they think about it.

However, everyone was a little excited.It's not about illusory things like being recorded in the annals of history, but...if it really reaches this level, maybe...everyone can have a better future.

Zhu Yuan didn't say much, and saw that a craftsman on the opposite side had sharpened and assembled a bamboo dragonfly in a blink of an eye... Well, this is made of wood, it should be called a wooden dragonfly... Take it, and signaled to Jin Sanhu: "The ultimate challenge, you guys If it can be done, everyone will be rewarded with another 10 taels of gold."

As they talked and fiddled with the wooden dragonfly, in everyone's eyes, they saw the little thing spinning and flying up in the room, and landed on the south side by the window, where a craftsman immediately caught it carefully and sent it over with a bow.

Zhu Yuan took it back and did not demonstrate again, but picked up the charcoal pencil again and changed a piece of white paper to start drawing: "The principle has been demonstrated to you, in fact, it is through the rotation of the blades to form a lifting force. Try it Try, can you use a steam model to drive the blades to make a machine that can fly, um... I call it a 'helicopter'."

Having said that, Zhu Yuan quickly drew a model of a helicopter.

After thinking for a while, he continued to draw, and continued, "As usual, don't limit your thinking. It can be like the one above or the one below. There are a pair of paddles at each of the four corners."

Drawn again, already similar to the later drones.

Then draw a third one.

Two pairs of paddles at the front and rear, similar to the later Chinooks.

He continued to explain while drawing: "The key to doing this is the weight, which requires all the parts to be as light as possible. If you can use wood, you must never use metal. Even if you can use cloth pieces and ropes instead, you must never use them. Wood, heh, and water and wax, anyway, my requirement is to be able to fly, I don’t think about how long it takes, so the water tank and wax tank can also be kept to the minimum. In short, this is a challenge with prizes.”

Previously, when the steam engine model was preliminarily completed, all the craftsmen in the yard were rewarded with 10 taels of gold each. This time... it was 10 taels again, and everyone cheered up immediately.

After Zhu Yuan finished speaking, Jin Sanhu immediately promised: "My lord, you guys will definitely do your best."

Zhu Yuan smiled: "Anyway, if you can't make it, you won't be rewarded. Well, remember to write and draw records when making it."

Regardless of whether it is successful or not, the corresponding experience will be a valuable research material.

Kim Sam-ho agreed again.

After saying this, Zhu Yuan got up, looked around the main room, and then went out to the west room.

A few craftsmen here are making steam boats.

Under the leadership of Zhu Yuan himself, the craftsmen mainly researched two models, one is a steamship, and the other is a propeller boat. The former existed in this era, and the hull was equipped with huge paddle wheels. The latter was naturally proposed by Zhu Yuan. Refer to Later generations relied on the stern underwater propeller to propel the kind.

Based on the two models, because of Zhu Yuan's encouragement, the craftsmen also diverged and designed more than ten kinds of patterns.

At present, it is mainly in kind.

When Zhu Yuan looked at it, it had already become a type of steamer, with a one-foot-long wooden hull, with a paddle wheel on each side, driven by a steam model.

Demonstrated on the spot, it can already travel well in the water basin in the house.

Of course, it is impossible to turn and stop. When you start to move, it will only go straight forward like a clockwork.

This is what Zhu Yuan wanted.

After all, I want a remote control... Now... I can only wait for the night...

There is nothing in the dream.

Another type of propeller, one of which is also basically formed, can be tested in the water tomorrow.

After inspecting it, Zhu Yuan felt that it was time to prepare for the show to Lao Zhu.

Then came to the next yard.

here...

Say it goes well and it goes well, and say it doesn't go well.

Fortunately, the basic full-scale model has been produced a few days ago.Unfortunately, it is one thing to make a model, and another to make it work.

This is also why I was emotional when I saw the mini water pump before.

Or two words: durable!

The water boiled, and the machine started to work, but it took less than a cup of tea time, because of various problems, such as air leakage in the machine body, broken parts, and so on... In short, comrades still need to work hard .

Not urgent.

Having seen both sides, remembering before, Zhu Yuan had someone call Jin Sanhu again, and brought him to the outer courtyard garden in the southeast of the mansion, which was Zhu Yuan's earliest residence here.

The place where Lao Zhu broke open at the beginning has now become a moon gate.

Zhu Yuan saw it for the first time, and thought about giving it a name, um...'Yulinmen' or something, but now the mansion still doesn't even have a plaque, including all the main halls inside, which are also empty. If the door wants a name, it is too much.

So give up.

Speaking of plaques and the like, I have already mentioned it to Lao Zhu before, please ask for the imperial pen.

got rejected.

Just say wait, lest you have to change it in the future.

Zhu Yuan also felt...that's the reason.

The key is...according to Zhu Yuan's current rank, the accurate personal house should be called 'Di'... imagine...'Zhu Di'...it feels weird, it seems that I have heard it somewhere, and it doesn't look like a good word.

Just wait.

Bringing Jin Sanhu to the garden here, Zhu Yuan got off his shoulders, strolled along the artificial lake in the garden, raised his hand and gestured, and said to Jin Sanhu: "Here, along the lake... Well, it’s too much to go around the lake, and it’s unnecessary. Anyway, you see, lay a few tens of feet of tracks on the lakeside, and then put a few model trains at a time. In the lake, ships and paddle boats are all It should be more lively. There are also water pumps that I have seen before, get a few more, and put them on the lakeside to pump water. You can see for yourself, come up with a plan in these two days, and then start to do it.”

Jin Sanhu respectfully agreed, but was still puzzled: "My lord, what is this for?"

"Show it to the ancestors."

"what!"

Seeing Jin Sanhu's stunned look, Zhu Yuan smiled and said, "It's not just the ancestors. At that time, I will invite His Highness the Crown Prince, all the princes and central ministers, so, if you do it, you will reach the sky in one step, but if Fucked up...well, can you swim?"

Jin Sanhu still had certain images in his mind, and he shook his head blankly: "Small...no."

"Then hurry up and learn," Zhu Yuan half-jokingly said, "If you don't screw up, I'll throw you into the lake, and you'll sink right away."

Jin Sanhu nodded again and again: "Small... small..."

Zhu Yuan stopped and wanted to pat Jin Sanhu on the shoulder, but unfortunately the other party was much taller than him even though he bowed slightly, and only his arm was patted: "Don't be nervous, you are a clock... you should have seen it before." To Zhengdi, right?"

Jin Sanhu shook his head: "No, my brother has seen it, the little one..."

Just about to say 'no such blessing', I suddenly remembered that the dynasty has changed, so I quickly stopped, and broke out in a cold sweat.

Seeing that his face turned pale for some reason, Zhu Yuan stopped teasing him, put away his expression and told him seriously: "In short, just do it well, put more models, and you won't be afraid if there are people lying down."
