Everyone looked at Zhang Hao, and from time to time glanced at Zhang Shengye next to him. Speaking of which, it was a bit too much to ask others about the principles of weapons. But everyone was really shocked.
Especially the crossbow, which has no tail feathers and can still move straight forward, is a bit beyond everyone's understanding.
Zhang Hao smiled: "Uncle Zheng, this... it's not convenient to talk about it for the time being. Please forgive me."
Disappointment flashed in everyone's eyes.
Zheng Changqiu apologized with a smile.
Zhang Hao did not want to continue: "When we discuss it later, the Zhang family will definitely tell everyone the truth."
Everyone's eyes lit up immediately, but then they looked at each other, and everyone saw the vigilance in their eyes.
The hidden meaning of Zhang Hao's words is obvious: Unless my Zhang family becomes a member of the Black Iron Guild, we will never let go of the eagle in sight!
The reason why Zhang Hao and Zhang Shengye did not hesitate to bring out the best crossbow bed at home was to use it as a stepping stone.
Zheng Changqiu laughed a few times, looked at some large and small complex iron circles next to him and asked, "What is this?"
"This...this is a bearing!"
"Bearing?" Zheng Changqiu picked up one and looked at it, and finally his eyes were full of surprise, "It is really a bearing, but the bearing can hardly feel any resistance!
Dear nephew, what can you say about this bearing?"
Zhang Hao smiled and said: "This is what our craftsmen figured out when they were bored.
Compared with traditional slip ring bearings, the resistance of such bearings is ten times smaller.
The most important thing is that such bearings are relatively easy to replace. If the bearing is damaged, there is no need to overhaul it, just replace it with a new bearing."
Everyone picked up a bearing and looked at it. Gradually, their faces became serious. Only by careful observation could they find that this small bearing was anything but simple.
Zhang Hao looked on with a smile.
Don’t underestimate this small component!
Without bearings, there would be no country on wheels, no high-speed and stable rotating industrial machinery, and no industrial power.
Bearings are the joints of industry!
In this world, bearings now have many applications. Vehicles, crossbow beds, city wall hanging doors, etc.
If the crossbow bed is the stepping stone for the Zhang family to enter the Weapon Refining Guild, then the bearing is an important product that the Zhang family plans to sell to the Weapon Refining Guild. It will also be the Zhang family's flagship product in the future, and it will be sold at home and abroad!
If you want to produce bearings, it is almost impossible without machine tools. It is not impossible to polish by hand, which will definitely make the craftsmen doubt their lives.
However, Zhang Hao also understands that one should not underestimate the wisdom of this world; simple machine tools are not complicated, and there is no telling that they will be developed soon.
But before everyone develops machine tools, it will be enough for the Zhang family to make a huge fortune relying on bearings. By then, the Zhang family will be able to engage in price wars and severely suppress their opponents!
But now, everyone is looking at these precision bearings and marveling.
Finally someone said: "This bearing technology alone is enough for the Zhang family to become a member of the Weapon Refining Guild."
Everyone was talking about it.
After a long time, Zhang Hao took the initiative to interrupt everyone's discussion, pointed to the third set of items, and introduced loudly: "This is a gift from the Zhang family to the Weapon Refining Guild."
Everyone looked at the neatly arranged various items, a little confused. Judging from Zhang Hao's tone, it seemed that these were great things. But why did they look like ordinary items?
Someone went over to identify it: "The purity of black iron is 62%? Mr. Zhang, are you sure this is a gift to the Weapon Refining Guild?"
Zhang Hao glanced at the other party with contempt and said loudly: "This gift is called: Standard!"
Zhang Hao looked around and started to introduce directly.
"Many people doubt how the Zhang family can produce thousands of tons of black iron a month! Today, I will tell you a reason, and that is - standards!
What are standards?”
Zhang Hao didn't say anything, and directly disassembled several identical bearings, bases, rollers, cages, and screws on the spot. Then, Zhang Hao randomly selected them and slowly reassembled the bearings.
Gently pushing the bearing in front of everyone, Zhang Hao said quietly: "This is the standard!"
Everyone's eyes froze. Sometimes, a thousand words are worth less than a single action.
Everyone refines their own weapons, and there is not even a hair on the standard. It’s too late to keep it secret. Even within some families, the standards for magic weapons and magic weapons are different!
Zheng Changqiu is a pragmatic person. He squatted down, picked up the screwdriver on the ground, and began to disassemble and assemble the bearing. He disassembled it very carefully and observed every part carefully.
With Zheng Changqiu as an example, even Mu Yingying and Mei Qianyun started to disassemble and assemble the bearings after taking a look at it.
Let’s compare every roller and every screw...
Unconsciously, it was noon. Zhang Hao clapped his hands, and the Zhang family's cooks immediately delivered a simple lunch.
Everyone had a few bites and then continued to disassemble and assemble the bearings. By mid-afternoon, Mei Qianyun, the fairy, had oil stains on her sleeves.
Then Zhang Hao didn't say anything. He asked the guard to lay down a piece of paper on the wooden board. He picked up the attack on the table and started drawing.
"This is called a 'meter ruler'. In order to refine production, we have adopted a unit that is smaller and simpler than the 'foot, ruler'. We named it 'meter' internally in our Zhang family.
The traditional units such as ‘Zhang, Chi’ are confusing and the units are large, which is not conducive to refined production.”
"This is a compass. Using the compass, I can easily draw countless identical circles."
"This is a protractor. We divide the circumference into 360 scales. Each scale is called a 'minute'. Each scale is temporarily divided into 60 seconds."
"This is a clock. We divide it into hours, one hour and 60 minutes, and one minute and 60 seconds. The division standard of the circle is based on the clock."
"This is a thermometer. We set the ice-water meter as zero degrees, and set the temperature of boiling water at sea level as 100 degrees. The middle is divided into 100 scales. Then rely on this standard to extend upward or downward.
Using a thermometer, we can visually express the temperature."
"This is a scale, this is a balance... We have adopted a new unit: kilogram, one kilogram is one kilogram..."
…
It was a wonderful performance. Zhang Hao kept talking for more than an hour, and finally even proposed a 'combination unit'.
For example: acceleration, pressure, etc.
However, Zhang Hao only mentioned all the combined units, but did not explain the meaning of the combined units. However, he also left an introduction and a seed.
Finally, Zhang Hao concluded: "Since we are going to build war weapons together, standards are very important. Only unified standards can achieve perfect fit between various magic weapons.
This ‘standard’ is the Zhang family’s gift to the Weapon Refining Guild!”
The applause sounded sporadic at first, but soon it became loud and continuous like ocean waves.
The so-called sword is given to the martyrs; the 'standard' is the 'sword' that these weapon-making guilds need. Its preciousness is far beyond the measure of wealth.
The birth of standards has allowed everyone to see a different world!
Amid the applause, Ji BuTong from Jiuyang Sect shouted: "I agree with the Zhang family joining the Weapon Refining Guild!"
