Since we can't get coal for the time being, Yunchao can only start by improving the combustion efficiency of charcoal.
First of all, Yun Chao aimed at the blowing equipment used by Blacksmith Hu.
Yun Chao discovered that the bellows used by Blacksmith Hu were very simple and outrageously primitive.
In my previous life, Yun Chao saw an old-fashioned bellows in his hometown when he was a child. He would push and pull a wooden pole with his hands and make a wooden box that would make a whirring sound.
The child is curious, and Yun Chao has even taken apart and looked at what structure is inside to make people say the idiom of a mouse drilling into the bellows and being angry at both ends.
Although Yun Chao couldn't remember clearly over time, he still knew the basic principle, it was nothing more than piston movement.
Piston sports, let alone Yun Chao, a quasi-doctoral doctor, can do it even if you have studied junior high school cultural knowledge after careful consideration.
Recalling the memories of his previous life carefully, Yun Chao began to write and draw on the ground with a black charcoal.
Many people were shocked when they saw Yun Chao drawing various ghost talismans on the ground like he was possessed.
Good, it’s different for the gods to come to earth. Brother Chao is going to do it!
If Yun Chao had just passed by, he would have been so powerful that he would have been tied up to drive away the evil spirits.
But now it is different. As Yun Chao's status becomes higher and higher, the more he acts differently, the more others are in awe of him.
Some things, if they are put on the miserable people, are feudal superstitions; if they are put on people with status, are supernatural powers, where can they reason?
If Yun Chao draws a genetic map, it may be difficult for him to design a drawing of an old-fashioned bellows, not only is it a piece of cake to draw a piece of cake.
Not long after, Yun Chao called several carpenters in front of him, pointed to the ghost painting talisman on the ground and said, "Several masters, look, can you make this thing?"
Yun Chao drew more than just one picture, including an appearance picture, an internal picture, a cross-section, and a vertical section, a total of several pictures.
Several carpenters looked at each other. They were watching each other just now, but they didn't realize that these were drawings!
It’s not that the carpenter is incompetent, but mainly because Yun Chao has marked too many symbols on the drawings, especially those Arabic numerals and letters. Who can tell what it is?
Seeing several carpenters confused, Yun Chao knew that he was a little too anxious, so he pointed to each picture and explained it to them.
Yunchao designed...oh, to be precise, it is something similar to a double-action piston bellows.
A rectangular wooden box with a partition inside the box, which divides the box into two layers.
There is a piston in the upper layer, which is connected to the pull rod, which is connected to the handle outside the bellows.
Where the piston and the partition were connected, Yunchao arranged some feathers to prevent air from overflowing.
The lower layer of the bellows is an air duct. There are two air vents at both ends of the partition, and an air inlet hole at each end. There is a flap on the mouth, so that the air flows in only one direction.
When using this kind of bellows, just pull and push the lever on the bellows and the air can be reciprocated and blown into the furnace.
When the air is supplied, the oxygen will be sufficient, the charcoal will burn faster and more fully, and the heat energy released per unit time will be more, and the furnace temperature will naturally rise.
Yun Chao was a tutor assistant to his tutor and was not a novice in teaching. Combined with the graphics, he gave a simple and easy-to-understand critique and several experienced carpenters quickly understood.
After understanding, several carpenters looked at each other.
I really didn’t expect that these ghost painting talismans were actually drawings of a new bellows!
They saw with their own eyes how Yun Chao designed these drawings in such a short time, and a clever new bellows were designed. This is amazing!
Of course, before the physical objects came out, several carpenters were still a little skeptical. Whether this thing works or not, can it really allow the blacksmith Hu to create a qualified gun tip?
No matter how suspicious the carpenters did not dare to neglect at all and immediately prepared to start construction.
After looking at it for a while, Yun Chao frowned because he discovered a problem.
Several carpenters have good skills, but one problem is that they do their own things.
You do yours, I do mine, and there is no division of labor. It seems that everyone wants to make a bellows.
"Stop, masters, you will do your own things. When will you do it well?"
Several carpenters were confused and didn't know what Yun Chao meant: "The boss, if you don't do this, what else can you do? This is how we have been apprenticing since childhood?"
Yun Chao shook his head: "Several masters, do you have to divide the work? For example, someone makes box boards and someone makes pull rods. Everyone makes different parts and then assemble them together. Wouldn't that be fine?"
"this……"
Several carpenters were reluctant to speak, but they didn't know how to answer Yun Chao's stupidity.
Don’t think that the ancients were all fools, and people have known about division of labor and cooperation for a long time.
In the past, when I worked, there was no division of labor and cooperation, such as the apprentice's tug-of-war and the master took out the tenon.
However, it would be nonsense to let different carpenters divide the work and cooperate.
"Our boss, our ink ruler is different, and the things we make cannot be filled!"
"What?"
This time it was Yun Chao's turn to be confused.
Didn’t it mean that when Qin Shihuang was attacked, he began to unify the weights and measures? Why is it still different now?
After some understanding, Yun Chao finally understood.
Although the rulers of several carpenters are roughly the same, if they reach the fine level, they will not work.
Every carpenter's ruler was passed down from his master.
Most of them are made by the master when he is a master, as a gift for his disciples to learn from his skills.
The problem lies here. Even if you are skilled, errors will inevitably occur.
Every time a generation is passed down, the error of the ruler will be larger.
Passing down from generation to generation, the error becomes larger and larger.
The final result is that every carpenter has a different ruler, and the gap is quite large.
After understanding the situation, Yun Chao scratched his head straight. It seemed that he had to start with the unified weights and measures. He had to continue doing things that Qin Shihuang had not done.
However, Yun Chao thought it was very simple but encountered big trouble.
If you want to unify the ruler, there is no door!
Several carpenters are used to using the ruler handed down by their masters. If they want to accept other people's standards, they must not!
These ancient craftsmen are all stubborn. You can beat them, or kill them. It is impossible to make them change the rules they have formed since childhood!
Besides, carpenters have become accustomed to the original standards. Sometimes they don’t need to measure the ruler at all when they work. You can tell how many feet and inches it is. It would be strange if they don’t have any problems!
