[Fourth Thursday Bullet! ] It's late at night, I wish you all a good night :)]

The carpenter put down the wooden tray in his hand in a dejected manner, shook his head and said, "Son, my old Mao is really convinced!" …… The same ruler should indeed be used! ”

Chu Fan smiled happily.

The way he thought of it was to speak with facts, which was the most convincing.

So after eating, he picked out ten Lumi guns, asked the carpenters to disassemble them all, and then reinstalled them in any combination, and the result was that all ten Lumi guns were reassembled without much effort - in this era, the Turkish handicraft workshops had the germ of industrialization, the degree of standardization was very high, and the tolerances had been controlled to the extent that they could be basically universal.

After loading the Lu Mi guns, Chu Fan took three more bird guns bought from Dengzhou, and also dismantled them for the carpenter to install.

The results are self-evident, how can the parts of the bird gun be fitted on top of another one because they are of different sizes?

Different from the carpenter's depression, Sun Hedou's eyes, who were carefully observing from the side, suddenly burst into ecstasy, and he grabbed Chu Fan and said, "Little uncle, I understand!" …… You're trying to make everything the same shape and size...... In this way, on top of the battle array, this gun is damaged, and it can be replaced by the same object...... The effect of ten bird guns can be worth twenty or even thirty...... Wonderful! Wonderful! ”

Chu Fan nodded again and again, and gave him a thumbs up for being able to figure it out so quickly.

After pulling everyone to sit down, Chu Fan began to explain the benefits of standardization at a deeper level: after all the parts are unified, first of all, the bullet can be fixed, and there is no need to prepare lead pellets of different sizes in advance as it is now, so as to adapt to the caliber of the bird's gun; And the caliber and thickness of the gun tube are the same, and the lead shot and medicine bag of the fixed bullet are the same, the risk of exploding the chamber is greatly reduced, and the safety is guaranteed.

In addition, in terms of logistics, the effect of standardization is also obvious: firstly, the bird gun can be disassembled into parts and packaged separately, and the gun tube can be packaged and sealed in a centralized manner, which can greatly reduce the possibility of rust; Since parts of the same shape are packed together, the size can be greatly reduced, and the burden of transportation will also be reduced.

By extension, standardization can not only be used in the production of birds, but also in many aspects, the most typical is the ship and vehicle, although the size of the ship and vehicle made by the Ming Dynasty is about the same, but a shipwright has a shipwright's own size, once the ship and vehicle are broken, it is impossible to change a rib or spoke!

As he spoke, Chu Fan began to depict a world that was incomparably wonderful in the eyes of the Ming people: everything in the house was universal, and the lid of the teacup fell? It doesn't matter, just bring the lid of another dropped teacup and you'll be able to use it; Two people got into a fight and smashed the window? You don't need to ask a carpenter to make it, just go to the carpentry shop and buy one; Broken in the car? See, there's a big car shop in front of you, buy another one and put it on the road......

One vivid example after another, immediately immersed everyone in the imagination of the kind of life that is convenient and desirable, after a long time, Tang Jiniu shook his head and said, "Son, what you said is good, but this needs to be done by all our craftsmen in the Ming Dynasty...... It's impossible. ”

"It's impossible to make Da Ming like this," Chu Fan said with blazing eyes, "But it's up to you to make Ushijima like this!" ”

Tang Jiniu was stunned, and his gaze at Chu Fan gradually became excited.

"As long as you work in this direction, Ushijima will become like this!" Chu Fan said firmly, "As the goods of our East India Company are sold to all parts of the Ming Dynasty, gradually the craftsmen of the Ming Dynasty will also be influenced by us, and one day, the entire Ming Dynasty will use the standards of our East India Company!" …… Standardization starts with us! Start now! ”

At this time, the jeweler sent the made vernier caliper, which Chu Fan just used to explain to everyone the most important concept of standardization - tolerance.

After using vernier calipers to measure the difference between the different parts of Dengzhou Bird Gun and Lumi Gun, Sun Hedou was the first to understand the tolerance - he felt that the so-called tolerance was the allowable error on the basis of not affecting the universality.

After understanding this, Sun Hedou enthusiastically joined the work of renovating the Lu Mi gun and installing the flintlock device.

But soon he ran into a problem - these craftsmen were illiterate, and even if they measured the relevant dimensions, it was too difficult for the craftsmen to remember this, and forget that.

"Little uncle, it seems that this standardization still can't be done," Sun Hedou complained to Chu Fan with a sad face, "How long should this bronze rod be, how wide should the flint iron plate be, and how deep should the fire gate be...... There are so many numbers involved that these craftsmen have to memorize them all, which ...... They can't do it, either. ”

Chu Fan smiled, but did not directly say the solution, but guided Sun Hedou to think about what to do.

After several rounds of back and forth, Sun Hedou finally understood Chu Fan's solution: teach craftsmen to read and count!

He couldn't help but gasp.

As a Western scholar, Sun Hedou is not as self-cherished as other scholars, and regards words as noble, thinking that they cannot be learned by lowly craftsmen.

He was surprised that Chu Fan's idea was too grand and too difficult to realize—how much time would it take to teach these craftsmen to read and write?

"Gongzai, Yang Ming Gong taught us that everything needs to be practiced before we can preach," Chu Fan looked at the three teachers and nephews with a surprised face and said, "What I want to say is that not daring to think about or do anything is the biggest obstacle to learning!" …… Think about it, when Yang Ming Gong entered Ji'an City alone, if he didn't dare to defeat King Ning, could he have raised tens of thousands of soldiers in just a few months? With King Ning's arrogance in Jiangxi, if he didn't dare to let go of it, could he capture King Ning? ”

Wang Yangming, who was sanctified on the ground, was a model of great respect for all scholars in the late Ming Dynasty, and Chu Fan brought out the matter of Pingding Ningwang, who was the most proud of him in his life, which really made Sun Hedou and them fall into contemplation.

"Therefore, if you want to do learning, if you want to do a good job, you must not only dare to think, but also be able to do! …… Teaching craftsmen to read and count may seem extremely difficult, but if you can't even think about it, you will never have a chance to succeed! Chu Fan continued to cheer up the three of them, "Besides, let's teach craftsmen, and we don't let them go to the field to fight, as long as they can understand the drawings, how much time can it take?" ”

In order to let the three of them understand what to teach craftsmen, Chu Fan made a demonstration that night.
