After observing for a while, feeling that the water was still a little slow, Zhu Yuan said to Jin Sanhu: "Increase the fire." ”

Kim Migo agreed, took out a small pair of tweezers from the side, picked a wick and lit it in the candle under the mini tank, and the original flame turned into two.

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

Zhu Yuan was interested: "Add more." ”

Kim Migo went on to add a wick.

The transmission and water outlet have accelerated again, and the water outlet of the mini pumping machine, which is similar to the field pump in later generations, has become like a water arrow.

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

Signaling that Jin Sanhu didn't need to add more water, Zhu Yuan pulled a chair and sat down, and said, "The quality is very good." ”

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

"It's still a good idea for adults, that bearing, durable." Jin Sanhu said, seeing Zhu Yuan stretching out his hand to the mini steam engine, he hurriedly stopped: "My lord, be careful of burning." ”

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

Jin Sanhu stretched out his hand to help pull away the small transmission belt, handed over tools such as crowknives and tweezers, and raised his hand to signal: "My lord, cut carefully, why don't you come with a small one?" ”

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

Both the pump and steam engine are embedded in a book-sized wooden base, which is fastened with iron nails underneath to ensure stability.

and there was no intention of taking it off.

Steering pump body.

The runner that is mainly used for pumping is about one inch in diameter, and the inlet and outlet are the thickness of the tachyon.

It can be seen that the upper and lower inlets and outlets are at the junction of the runner, as well as the shafts on both sides, although they have been polished, there are still surging welding marks.

There was welding in this era.

In fact, even as early as the Shang and Zhou dynasties, welding techniques have appeared, of course, not the later electric welding, but also not casting, that is, the welding of different metal components.

Although the small water pump in front of him looked like it was integrated through welding and grinding, Zhu Yuan still used a crowknife to open the small things along the pump body under the guidance of Jin Sanhu on the side.

The overall bronze material is easy to pry up.

A moment later, a series of smaller parts appeared in front of Zhu Yuan, mainly a short steel shaft, two mini-bearings slightly smaller than copper coins, a runner connected to the transmission belt on the outside, and a water wheel embedded in the shaft.

What makes Zhu Yuan more emotional is that all 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 tank is boiled dry, which can already be described as sophisticated.

While fiddling, Zhu Yuan also noticed another piece.

In the mini bearing, 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, sure enough, it is a steel ball.

Seeing this, Jin Sango, who was next to him, took the initiative to explain: "My lord, the bronze balls are really not durable, and the small ones are replaced with iron ones." ”

】

Zhu Yuan thought about it, and then he understood a little, and asked, "Can you make it bigger, one or two inches in diameter?" ”

Jin Sanhu said: "Yes, just be slow." ”

"That's not possible," Zhu Yuan shook his head slightly: "If you can only make one steel ball a day, it's meaningless." ”

Jin Sango remembered the bearing workshop he had personally visited by the river, and nodded his head.

This kind of steel ball the size of a mung bean is easy to car, but if it is made to a size of one or two inches, the level of pigeon eggs to eggs, in the eyes of his craftsman, the main thing is that the size is not easy to grasp.

To put it simply, the use of iron knives to turn copper balls, the kind of cylindrical iron turning tools in the riverside bearing workshop, can do dozens of copper balls will not have much wear, but if you use iron to turn iron, the wear will be very fast. What's more, the turning method focuses on one-time molding, if the size of the turning tool is worn and the size is deviated, it is difficult to ensure the roundness of the ball if you want to carry out secondary processing on the finished product, and you can only return to the furnace to rebuild.

Putting this matter aside, Zhu Yuan fiddled with it and asked some more details.

Finally, pushing aside the already scattered pumping machine and asking for a pen and paper, Zhu Yuan said: "Since the pumping machine has been made, I will give you some challenges and try others." ”

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

Steam Trucks, Steam Excavators, Steam Dozers, Steam Rollers, Steam Cranes......

After drawing a few in a row, Zhu Yuan remembered one and asked Jin Sanhu: "Do you know bamboo dragonflies?" ”

Jin Sanhu nodded, and put his hands together and fiddled: "That's it, can you fly that?" ”

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

Jin Sanhu was about to make a move, but Zhu Yuan stopped him and motioned to several other craftsmen: "You guys come and do it." ”

Then Kim Sango returned to him and began to explain: "Steam truck, you will know what it is by looking at the picture, and you don't need a track to run." Steam Excavator ...... The main thing is the bucket in front, imagine that it is as big as our house, and a shovel can shovel out hundreds of catties of soil. Also, bulldozers, road rollers, cranes, these similar, are all large machinery that can build roads and houses, the picture is just a style, my requirements are, as long as a simple purpose can be achieved, for example, it is to dig the soil, it is to bulldozer, it is to compact the road back and forth like a mill, it is to lift thousands of pounds of things to a height of more than ten zhang, you think about it, can it be achieved? ”

Jin Sango looked at the pattern drawn by Zhu Yuan, twisted his eyebrows slightly and thought for a moment, then nodded: "My lord, if it is just a simple action, it should not be difficult. ”

"Then think about it a little more," Zhu Yuan smiled and nodded to the paper: "For example, this truck, to be able to move forward, backward, but also to turn left and right, after all, the road can't be straight, and there is speed, which can speed up and slow down, heh, this, but it involves your industry, probably the combination of gears of different sizes, you can achieve speed change." ”

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 is bigger, according to what the adults said, the size of the house, the small ones are a bit eyebrow-raising, but it will take a lot of time, and it will cost a lot of money." ”

"Heh, you have the time, regardless of the cost," Zhu Yuan smiled, and drew a circle on the truck: "Actually, this thing, as long as it can do basic steering and behavior, it is very enough for the time being, and the key is also to be large, and the body is the size of our house, and it can pull tens of thousands of catties of things at a time." ”

Jin Sango smiled with him: "Adult, think about this picture...... If you can really see it in the future, it will not be in vain. ”

"As long as you can do it well, you will definitely be able to see it, after all, you have to achieve it, it belongs to the creator of history, and it can go down in history in the future."

Jin San's body couldn't help but bow a little, and the corners of his mouth seemed to twitch: "Big ...... My lord, go down in history...... A small lowly craftsman, don't dare to think about it......" said and shook his head: "Don't dare to think about it." ”

The other craftsmen in the room were also keeping an eye on the conversation.

History?

They didn't dare to think about it, and they didn't think about it.

However, everyone was a little excited. It's not about thinking about something as illusory as going down in history, but ...... If it really reaches this level, maybe it ...... Everyone can have a better future.

Zhu Yuan didn't say much, and saw a craftsman on the opposite side sharpening and assembling a bamboo dragonfly in a blink of an eye...... Well, it's wooden, so it's supposed to be called a wood dragonfly...... took it and motioned to Jin Sango: "The ultimate challenge, if you can do it, each of you will be rewarded with another 10 taels of gold." ”

As he spoke, he played with the wooden dragonfly, and in everyone's eyes, they saw the little thing spinning and flying up in the room, and landed near the window on the south side, where a craftsman immediately caught it carefully and bowed down to send it over.

Zhu Yuan took it back into his hand and did not demonstrate it again, but picked up the charcoal again and changed it to a blank piece of paper and began to draw: "The principle has been demonstrated to you, in fact, it is through the rotation of the paddle blades to form a lift. You guys can use the steam model to drive the paddles and make a flying machine, huh...... I call it a 'helicopter'. ”

With that, Zhu Yuan quickly drew a model of a helicopter.

After thinking about it, he continued to draw, and continued: "As usual, the thinking should not be limited, it can be like above or below, and there is a pair of paddles at each of the four corners. ”

Drawn again, already similar to later UAVs.

Then a third one was drawn.

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

Continue to explain while drawing: "The key to doing this is weight, which requires all parts to be as light as possible, and those that can be made of wood are absolutely not metal, and even, those that can be replaced by cloth and wire ropes must not be made of wood, heh, and water and wax, anyway, my requirement is to be able to fly, and how long it will take is not considered for the time being, so the water tank and wax trough can also sit to the minimum." In short, it's a prize challenge. ”

Before the preliminary completion of the steam engine model, all the craftsmen in the yard were rewarded with 10 taels of gold each, this time ...... It was another 10 taels, and everyone immediately cheered up.

After Zhu Yuan finished speaking, Jin Sanhu immediately promised: "Adults, the little ones must do their best." ”

Zhu Yuan smiled: "Anyway, if you can't do it, there will be no reward." Well, remember to make a good record of the text and drawings when you make it. ”

Whether it succeeds or not, the experience will be a valuable research resource.

Kim Sango agreed again.

After saying this, Zhu Yuan got up, looked around the main house, and then went out to the West House.

Here, a few craftsmen are making steam engine ships.

Under the personal leadership of Zhu Yuan, the craftsmen mainly studied two models, one is a steamer, the other is a propeller boat, the former is in this era, the hull is equipped with a huge paddle wheel, the latter is naturally proposed by Zhu Yuan, referring to the kind of propeller that later generations rely on the stern underwater propeller to propulse.

On the basis of the two models, because of Zhu Yuan's encouragement, the craftsmen are also very divergent and have designed more than ten kinds of patterns.

At present, it is mainly made in kind.

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

Demonstration on the spot, it is already good to travel in the water basin in the house.

Of course, you can't make a turn or stop, and you can't start moving, like clockwork, and you will just go straight ahead.

That's what Zhu Yuan wants.

After all, I want a remote-controlled ...... Present...... Can only wait for the evening......

Everything in my dreams.

The other propeller types, one of which is also basically formed, can be tested in the water tomorrow.

After taking a look, Zhu Yuan felt that he could start preparing for showing it to Lao Zhu.

Then I came to the next yard.

This way......

It is smooth to say that it is smooth, and it is not smooth to say that it is not smooth.

Smoothly, the basic full-size model, which was made the other day. The unfortunate thing is that the model is one thing to make, and whether it can work well is another thing.

This is also why I felt emotional when I watched the mini pumping machine before.

Again, two words: durable!

The water boiled, the machine moved, but after less than a cup of tea, because of all kinds of problems, the body leaked, the parts were broken, and so on...... In short, comrades still need to work hard.

There is no hurry.

I have seen both sides, and I remembered that before, Zhu Yuan asked people to call Jin Sanhu again, and took 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 crashed into it at the beginning was now repaired into a moon gate.

The first time Zhu Yuan saw it, he thought about it, he should give it a name, well...... 'Yulinmen' or something, but now the mansion still doesn't even have a plaque, including the main halls inside, which are also empty, and it is too much for this small door to want a name.

So I gave up.

Speaking of plaques and the like, I have mentioned it to Lao Zhu before, and I asked for a royal pen.

Denied.

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

Zhu Yuan also felt ...... That's the truth.

The key is...... According to Zhu Yuan's current rank, the accurate personal residence should be called 'first'...... Imagine ...... 'Judi'...... It feels weird, it seems like I've heard it somewhere, and it doesn't look like something good.

Just wait.

Coming to this garden with Jin Sanhu, Zhu Yuan lowered his shoulders and walked along the artificial lake in the garden, raising his hand and gesturing, and said to Jin Sanhu: "Here, along the lake...... Well, going around the lake is too much, and there's no need. Anyway, you watch, pave dozens of feet of track on the lakeside, and put a few model trains at a time when the time comes. Then there is the lake, there are steamers and paddle boats, and it is more lively. There are also pumping machines that I have seen before, get a few more and put them on the lakeside to pump water. See for yourself, come up with a plan for the next two days, and then start working on it. ”

Jin Sango respectfully agreed, still puzzled: "My lord, what is this for?" ”

"Show it to your ancestors."

"Ahh

Zhu Yuan saw Jin Sanhu's momentary stunned appearance, and said with a smile: "Not only the ancestors, when the time comes, I will invite His Royal Highness the Crown Prince, all the princes and important ministers over, so, if you do a good job, you will ascend to the sky in one step, but if you mess up...... Well, can you swim? ”

Jin Sanhu was still entangled in some pictures in his mind, and shook his head blankly: "Small...... No. ”

"Then hurry up and learn," Zhu Yuan half-jokingly: "Lest you be messed up, I will throw you in the lake and sink directly." ”

Jin Sango nodded again and again: "Small...... Small ......"

Zhu Yuan stopped and wanted to pat Jin Sanhu on the shoulder, but unfortunately the other party was still much taller than him even if he bowed slightly, and only slapped his arm: "Don't be nervous, you are the clock...... I should have seen Emperor Zhizheng too, right? ”

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

Just about to say, 'There is no such blessing', but suddenly remembered that the dynasty had changed, and hurriedly stopped, and was shocked into a cold sweat.

Zhu Yuan saw that his face turned white for some reason, so he didn't tease anymore, put away his expression and said seriously: "In short, you just do it well, put more models, and don't be afraid of those who are lying in the nest when the time comes." ”
