Chapter 157

"Bring another piece of carbon, yes, carbon instead of peat, and bring a thin piece of wood...... Wang Yang gestured at the iron bar, which is not bad, the thickness is very flat, and the width seems to be a little problematic, but it doesn't matter, the edge is a straight line.

Then, Zhao Laosan and Steward Niu looked at Wang Yang in a daze, stretched out his ring finger, and then gestured on the thin piece of wood, and finally took the piece of bamboo charcoal and carefully drew two black marks, as if he was a little dissatisfied, erased one of them, and then drew it for a long time.

After drawing five or six times, Wang Yang seemed to think that there was an audience around him, turned his head and smiled at Zhao Laosan. "That's one centimeter, that's one centimeter."

“…… Is the width of your nails a centimeter? Zhao Laosan smashed his mouth, this Wang Xiaodong is also very narcissistic, compared his fingernails to the blind stroke, and told himself that this is the length created by his new invention.

Is this kid going to do something? Aren't you afraid that the government will know that he has changed weights and measures privately, that is not a trivial matter. Zhao Laosan subconsciously raised his head and glanced at Steward Niu, but Steward Niu's expression was very confused, and he didn't understand the power at all.

Zhao Laosan could only bite the bullet and say. "Wang Xiaodong's family, this weights and measures can only be changed by the people of the government, but we ordinary people can't do it, if we let the government know, it will be a lawsuit. This is equivalent to a shortage of two pounds......"

Wang Da Inventor looked at this product with a black line, oh my god, I never thought that he who had always been law-abiding would be educated by an ancient working-class brother.

"I said, big brother, don't you care about your wife? Wang is just tinkering with some gadgets for his own use, you can't be so online, if you don't like it, then I'll find another blacksmith shop. ”

was scolded by Wang Yang like this, that Zhao Laosan thought about it, this young son didn't look at the kind of gangster with a full face, besides, the price offered by the other party was quite real, and his own egg hurt a wool.

Zhao Laosan was very interested and closed his mouth, while Wang Yang continued to work hard, and soon, a standard ruler was drummed out by this goods. "The distance between every two lines is one centimeter I need, and the short line in the middle represents five millimeters, don't you understand? Well, that's half a centimeter......"

It took a lot of effort to make Zhao Laosan understand the length unit on the iron ruler, no way, the time is tight and the task is heavy, Wang Yang has no way to make a ruler with even millimeters in such a short period of time, so he can only do so.

Anyway, there are not a lot of iron fixtures and wear-resistant parts needed for hydraulic machinery, as for those parts that Zhao Laosan couldn't handle before, under Wang Yang's personal description and guidance, Zhao Laosan finally understood what Wang Yang meant, and decided to start making it now.

Anyway, what he has here is the current pig iron, wrought iron, taking advantage of the old blacksmith to make parts, Wang Yang wandered around in this blacksmith, this blacksmith shop is really as the cow steward said, it is the largest blacksmith shop in the vicinity, several masters and many apprentices are busy, not only to make hoes and other farm tools, but also to make kitchen knives or iron pots, or to make knives.

And in the corner of the store, there are all kinds of scraps. Wang Yang asked the little guy who Zhao Laosan had arranged to accompany him, and learned that this pile of waste materials covering an area of nearly three or four square meters included both scraps for smelting steel, as well as defective products that were broken and difficult to return to the furnace for re-refining.

Wang Yang was curious to pick and choose there, these things are too familiar, when he was in the College of Engineering, some of the laboratories were really like this smith's iron shop.

After looking at it for a long time, Wang Yang found a more serious problem, that is, although the craftsmen of this era used coal as fuel, and the smelting furnace was also equipped with a blower, the strong smell of sulfide made him frown.

Eyes fell on the pile of fuel, it seems that the wisdom of the Chinese nation is really infinite, and in the Song Dynasty, coal has begun to be widely used.

However, as a smelting industry, the sulphur content of coal almost determines the quality of the steel smelted. Although there are many methods for desulfurization of coal, there are ...... There's an egg.

Driver Wang is neither the director of the coal mine, nor the head of the blacksmith shop, nor the high-level personnel of the Song Dynasty, even if he has more technology, he has to be willing to use it.

Steward Niu looked stupidly at Wang Yang standing in front of a pile of waste materials and coal piles, worried about the country and the people, and didn't know what to mutter, and kept sighing, and couldn't help but roll his eyes, it seems that a great talent is a great talent, and even looking at a bunch of broken things can be sad, such a realm is really not something that a layman like himself can achieve.

With the personal guidance of Wang Yang, the old driver, and the joint efforts of Zhao Laosan and other blacksmiths, it only took one afternoon to build three sets of parts and components that Wang Yang needed.

However, the only thing that makes people speechless is how to thread the screw car, Wang Yang thought hard for a long time, and finally an old blacksmith thought of a solution, that is, chisel.

First draw the line with something, and then use a harder small chisel, little by little, after hearing this method, Wang Yang was overjoyed, and quickly let the old driver get started, although at the beginning of the scrapped two original screws, but after proficiency.

It took the old craftsman less than a pillar of incense to make a bolt, at least the nut, although it was an inner wire, was more difficult, but the screw was big enough to be knocked out.

When Wang Yang saw that the bolts in front of him were about the thickness of a thumb, and a total of sixteen bolts that had been screwed on the nuts were placed in front of him, Wang Yang's heart was filled with a great sense of satisfaction and achievement.

In addition, there is a vernier caliper made from several pieces of iron. With this thing, not to mention decimeters, centimeters, even millimeters, you can use it to measure.

It's just a little rough, but in terms of the level of tools of this era, it can be regarded as extremely precise.

"Thank you, master, if it weren't for you, Wang would really not have been able to make such a good thing for a while. Well, how about I order another fifty bolts like this, still at the same price? After Wang Yang gratefully bowed to the old blacksmith to show his gratitude, he turned his head to Zhao Laosan and asked.

Zhao Laosan's chest slapped loudly. "Naturally, there is no problem, as long as you want it, I guarantee that you will be able to get it for you."

Early the next morning, Wang Yang shook his head, left Master Li in Yihong Building, and went to the printing workshop outside the city.

"Maverick, how's it going, are you still used to staying here?" After Wang Yang walked in the door, he greeted Niu Dacai, the eldest son of the cow steward, who was also hired by Wang Yang and became the shopkeeper of the printing shop.

"The owner is here. What can be done here, by the way, the masters are busy now, the day before yesterday, the owner of a bookstore came over to about 500 books, and now most of the editions have been carved and printed. Niu Dacai, who was nearly thirty years old, saluted Wang Yang and said with a smile.
