Chapter 133 Bronze Mirror (Ask for Recommendation Votes)

In the fields of Kelongli, a small blue flower bloomed.

This is a kind of barren herb, called cranberry, the leaves and stems can be eaten, and those that cannot be eaten can be made into pickles.

However, it is not a famine year, and it becomes a green fodder and wild flower for livestock.

The local folks call it February Orchid.

According to legend, Zhuge Liang became Liu Bei's military advisor and general, and was in charge of military rations and taxes.

On a patrol, I saw a kind of vegetable, and learned from the old farmer that this dish was full of treasures, and it was the ration of the master when the green and yellow were not available.

So he asked the old peasants about the yield and planting method, and ordered the soldiers to plant when they were in the fields, on the one hand, to supplement the military rations, and on the other hand, to use it as livestock feed, which was economical and cost-effective, killing two birds with one stone.

Therefore, it got another name - Zhuge cuisine.

The terraced fields in the back mountains have proved to be feasible, and the silt in the swamp is thickly covered with a layer and poured into the mountain spring, which is the fertile field.

The swamp has been opened into a ridge and a waterway, and on the ridge, it has been planted with wild grass by Su You, and this year it will be white.

With the rope making machine and water glass, the twine in Kelongli was of high quality, and the old people in the village could not be idle, so they began to learn to weave fishing nets.

After the beginning of spring, the third brother and the fifth brother went to the surrounding towns and villages, and in a laugh, they collected 300 gilts at a super low price.

The big and small butchers are so busy that they fly, and the pig cutting craft is advancing by leaps and bounds.

The chickens and ducks began to come out of the shed, and the land temple came to collect eggs once a week.

The babies have little strength, Su Xiaomei thought of a way, when cutting cold chicken pieces, first put the knife on the meat, and then smashed it with a wooden stick, so this dish was called "Bangbang Chicken" by the merchants, and the beef with the feet, back to the pot meat, became the three major meat dishes that the merchants must order.

The villagers are busy trimming the fields, after applying the manure in the cattle pen and pigpen in the field, they will carefully turn out a piece of land, poke out the small mud in the mud with their feet, knead them into a pulp one by one, and level them with bamboo chips, which is the seedling bed.

The plan of the year lies in the spring, and the plan of the day lies in the morning.

Early in the morning, in the rhythmic sound of the forging machine, a child's voice came loudly.

"Whoever has a herdsman on land must keep watch at the barn at four o'clock. If the country has more wealth, those who are far away will come; If the land is opened, the people will stay; If the warehouse is solid, you will know the etiquette; If you have enough food and clothing, you will know honor and disgrace; The degree of service is six pro-solid; Four-dimensional Zhang, then the monarch orders the ......"

"The prosperity of government is in accordance with the will of the people; The abolition of government is against the will of the people. The people are evil and worried, and I am happy; The people are evil and poor, and I am rich; The people are in danger, and I am safe; The evil of the people is extinct, and I am the ...... of childbirth"

"Take the home as the township, and the township cannot be the same; Take the township as the country, and the country cannot do it; Take the country as the world, and the world cannot do anything. Take the home as the home, the township as the township, the country as the country, and the world as the world. Needless to say, those who are far away do not listen; Needless to say, different towns, far away; Needless to say, different countries, far away do not follow the ......"

Zhang Qi and a few younger brothers were learning to forge small iron beads, and his mouth was not idle: "Listening to the little young master studying, I feel comfortable." ”

Liu Si poured a bucket of steel balls into the bead bucket and asked a younger brother to start the bead grinder: "You concentrate on it, it's not fun to press your hands." ”

The machine turns, and the beads tumble down the equidistant spiral groove from the center of the bead grinder into another barrel, which is ground again by the grinding disc above the helix.

A child took a micrometer and took a sample to check: "Fourth brother, this time it's almost over." ”

Liu Si took the ruler and checked it, and said, "Well, the next thing is polishing, everyone is optimistic." ”

The balls were poured into a drum, oil was added, the drum was turned, and some very fine slurry-like abrasives were added, and soon the misty balls became shiny.

After washing the ball mill several times, the added abrasives became more and more delicate, and the steel balls obtained became brighter and brighter, and finally they were able to shine a human figure.

Liu Si handed over the small steel balls to each baby, and the babies looked at the reflection on the beads, and they became round pigs' heads, and they couldn't help but make fun of each other.

Liu Si placed the bearing inner ring of the lathe in the shallow recess of an iron plate, put a steel ball into the fixing ring of the inner ring, arranged them one by one, and then took out a dark red outer ring from the furnace and put it on, knocked it a few times with a hammer to make the outer ring in place, and then picked up the iron plate with a long hook and put it into the cold oil tank.

After a few clicks, a ball bearing was made.

Liu Si used the iron tongs to open and jam through the inner ring, and with a slight flick of the outer ring, the bearing immediately rolled rapidly.

Liu Si said triumphantly: "Bearings can be made more than a dozen at a time, this is a demonstration, just make one for everyone to see." As the young master said, friction is related to the contact area between objects, and balls can minimize the contact area, so the friction is much smaller than that of roller bearings, everyone understands, right? ”

A little child said: "There is also the principle of heat expansion and cold contraction!" The outer ring can trap the beads in the inner groove, which has something to do with this. ”

Liu Si nodded: "Well, twenty-three you are very smart, but it is a difficult problem to determine the shrinkage ratio of the steel, the depth of slotting, the temperature of the outer ring is determined, and the difficulty is not one or two." From principle to practicality, we have gone through countless trials to get this experience. ”

"The little master said, in addition to understanding the principle, the achievements of science and engineering, in addition to understanding the principle, also need a large amount of experimental data for reference, so don't think that you can do everything if you learn theoretical knowledge!"

Zhang Qi said: "That is, this time the rose red bottle sent to Bianjing, the pottery coal group has wasted nearly 1,000 catties of porcelain clay, hundreds of embryos, and four of the five porcelain tires were destroyed after the glaze was burned, this is what the little young master said - easy to know but difficult to do!" Quite a few? ”

Su You closed the "Pipe" and said: "Yes, but this idiom comes from Shangshu, but there is another layer of meaning, which is about the truth of being a human being - it is easy for people to know what is wrong with them, and they also know that these faults are wrong, but they are unwilling to change." ”

Therefore, there is a gentleman who refrains from self-denial, restrains his selfish desires, and is strict with himself. Defeating others is not a skill, overcoming those bad faults in oneself is the ability. ”

Zhang Qi felt that the little master was talking about him, so he turned his head and changed the topic: "Fourth, have you finished it over there?" Come and give a hand! ”

Liu Si waved his hand and took out a copper plate: "I don't have time to pay attention to you, the girls are clamoring for mirrors, and now that the abrasive has come out, I'll bring them back today!" ”

Zhang Qi was so contemptuous: "There are quite a lot of flowers, and I know how to please the little lady all day long." ”

Su You said earnestly on the side: "Little Seventh Brother, your current engineering dog attribute is getting more and more serious, and in a few years, don't cry if you can't find a daughter-in-law." ”

A few people laughed and began to deal with the mirror, Su You said: "I heard that there is a kind of treasure mirror, which is usually no different from ordinary mirrors, but once the sunlight is reflected, there will be text patterns in the light and shadow on the wall, and we will try to do it today." ”

Liu Si rubbed abrasive cream on the wool wheel: "What the little young master wants to do, it has not been impossible." ”

Place the copper disc on a flat surface, let the wool wheel rotate, then adjust the lead screw to press onto the copper pan, and then push the copper disc to start grinding.

Originally, there was a shallow lotus flower cast on the copper plate, but after changing several times of different mesh abrasive paste and wool wheels, it was soon ground to almost no traces, and the copper plate became smooth and clean, and could be used as a mirror.

After washing the copper plate with alkaline water, several people ran to the sun again: "Come, see the effect." ”

Ba Cheng was weaving baskets under the eaves, and was shaken by the bronze mirror, and looked up and scolded: "What are you tossing around again!" ”

The babies hurriedly turned the light in a different direction, and a spot of light appeared on the pink wall, and under the spot, there was indeed a faint trace of a lotus flower.

The babies cheered in unison: "Also! It worked! ”

Su You took the bronze mirror and looked at it: "No, no, no, you can see some traces of lotus flowers on this mirror, grind a little more and grind a little more, and then make up a lotus flower behind the mirror, so that others think that it is from behind the mirror, then you can bluff people!" ”

Zhang Qi smiled wickedly: "The little young master has a lot of eyes!" But I like it! ”

So the three of them started again with great interest.

After tinkering for a while, the three of them looked at the clean spots on the wall again: "Damn, it's too much!" ”

Liu Si complained: "I blame you!" See! Now it's a big monk's head! ”

Zhang Qi also replied: "The big monk has a ring scar on his head, which is obviously the head of the little monk." ”

Su You put his hand on his head: "What's that...... Failure is said to be a success, and it is mother-in-law, anyway, this thing can still be used as a mirror, fourth brother, you just take it to fool your sisters......"
