"But if your Majesty eats something and dismantles it, we won't have the female parent in our hands. Please think again..."
Cai Xin was a little worried and hurriedly said to Liu Deng.
"This thing is just a pile of rotten wood. What do you want to keep in your hands as a mother copy? The mother copy should also be made of iron. Come over here!"
Liu Deng smiled lightly. The most important thing in casting this thing is of course the making of the first mold. In this day and age, if you want to cast something qualified, it will take several days just for the craftsmen to make the mold. time.
Moreover, the ones they make are the simplest ones. As for the ones with exquisite patterns, don’t even think about them...
But Liu Deng didn't have that much time to wait. They slowly made it one by one. When they were all done, the day lily was cold, and Liu Deng wanted to teach them a simpler method.
Now that we already have wooden parts, it is of course easiest to use the soot blowing method to make them.
The so-called soot blowing method is to put the wooden parts in the clay. After the production is completed, put the pottery model in a high fire to burn. After the mold solidifies, the original wooden parts are removed from the pre-reserved holes. The ashes turned into parts are blown out.
Then you get a complete mold, isn't the rest simple?
Of course, the iron parts cast in this way still have to go through the final process, which is the so-called quenching. Otherwise, the cast parts will be too brittle and have no toughness. If they encounter a slightly stronger collision, they will immediately It will break into pieces.
But at this time, this thing is enough.
After Liu Deng's guidance, the progress of the entire project suddenly accelerated.
By the time the sun was nearing the sky, the first batch of gears had already come out. Everyone's eyes widened when they looked at the rough iron lumps.
Is this casting still possible?
"Your Majesty, is this method the secret method of casting bells taught in the palace?"
Cai Xin's eyes suddenly lit up, and she looked at Liu Deng with admiration.
"What's the way to make a bell?"
Now it was Liu Deng's turn to be confused.
"It is said that there is a secret method of casting bells in the palace, which can cast beautiful bells and tripods. However, it has been passed down by word of mouth by the master craftsmen in the palace and has never been shown to anyone!"
Hearing Cai Xin's explanation, Liu Deng was stunned and said for a long time, has this method been available for a long time?
Regardless of whether it is secretly passed down by the palace or not, I learned this stuff from the Internet in later generations. Is it possible that they still dare to come here to ask me for patent fees?
"You don't care what he does, is it easy to use? It's just that the thing that comes out is too strong and needs to be remade!"
"This subordinate understands. I once heard an old man in the clan talk about a simple method of making swords. I guess it makes sense!"
I didn't expect that this guy is somewhat basic. It's easy to put it that way.
Cai Xin skillfully directed the craftsmen to put the gears that had just cooled down and put them back into the furnace for reheating. After they were red-hot, he took them out again and placed them on the fine sand, waiting for them. Cool down slowly.
The officials watching were all dumbfounded. The problem they were blaming Cai Xin just now has now been solved.
Not to mention it's been seven or eight months, not even a day has passed since then, but this guy actually got it done...
What remains is the problem of cutting tools. If this thing is used to process iron, it will naturally be more difficult, but now if it is only used to process wood, it will be much easier.
Even ordinary iron knives were adequate for the job. Cai Xin was a little excited. It was only in the evening that the molds gradually cooled down.
Cai Xin started assembling it overnight, with all the craftsmen assisting. Two hours later, the first truly hand-made lathe was born.
Although this thing can only rely on human power now, it has already amazed these craftsmen.
Of course Liu Deng's body bones can't be manipulated, but the craftsmen should not make it too easy to operate.
I saw a guy with big arms and round waist, tremblingly placing a wooden embryo on the machine, inserting a sharp knife, and then began to turn the handle.
As he continued to turn, the wood continued to rotate on the machine, and then a straight arrow shaft was cut out.
The guy who had just been fighting with Cai Xin rushed out from the crowd, removed the arrow shaft from the machine with trembling hands, held it carefully in front of his eyes, closed one eye and began to compare.
"This this……"
"Master Xu, what do you think of this thing? If we have a hundred of these machines, do you still think it's difficult to make ten thousand machines a day?"
Cai Xin actually learned how to be sarcastic. Liu Deng stood aside and laughed without saying a word. This kid has learned it badly.
But this is his home court, so let him handle the rest.
"I also have a drawing here. In the next few days, a special bureau will be set up, called the Foundry Bureau. You will prepare all the hands from top to bottom. It will produce what you need, and I will open the other side. To make this thing with full power, I need 30,000 pieces. From now on, the craftsmen who supervise it will be specially assigned an iron seal, and the things they make will be stamped with their own seals. Whoever produces something that has problems will be responsible. responsibility!"
Implementing responsibilities to people can alleviate people's slack to a great extent.
Of course, in this day and age, people's hearts are still very simple, especially these craftsmen, who still haven't learned how to cheat and cheat.
"promise!"
Cai Xin originally wanted to say something, but since it was Liu Deng's order, he remained silent.
Seeing that it was already dark, Liu Deng ordered each person to be rewarded with five strings of gold, and then went back to the palace.
On the way back, Liu Deng couldn't help but laugh at himself again. This king really got up earlier than a chicken and went to bed later than a dog.
I don't know if it's a good thing or a bad thing that I'm so pushy, but now that the situation is urgent, I don't care so much.
The next step is the issue of steel production. There are already large coal mines and iron mines in the country of Dai, but until now, the steel produced every year cannot even reach one-third of the steel it needs. This technology can be considered a goddamn thing. I'm so behind...
"Your Majesty, the Grand Tutor is in the study asking to see the King. He has been waiting for the King for a long time!"
I had just entered the house and was preparing to get something to eat and take a bath. When I went to bed early, someone came to report immediately. Taifu Zhang Tu asked to see him.
Liu Deng suddenly had a bad feeling in his heart. Could it be...
