It took the two of them a busy day to finish drawing a bicycle. Pen ~ fun ~ pavilion www.biquge.info Li Xiang picked up the dozens of drawings drawn and looked at them again, the main parts drawings, assembly drawings, the materials, sizes, and specifications on each drawing are marked in detail, and some places also use three views, although there are no tolerances, surface finish and other parameters, but the existing information is more than enough to make an original bicycle.

The next day, Li Xiang asked Yu'er to find all the famous carpenters and blacksmiths in the city, in fact, Li Xiang had inspected them before, so this time he quickly settled on two carpenter shops and blacksmith shops that happened to be relatively close to each other. The master of the carpenter shop is in his forties, his name is Wang Dali, and Li Xiang only looked at a few items he made, and he knew that this person's craftsmanship was not bad.

Wang Dali looked at the drawings brought by Yu'er, and was very strange why he made this thing, but Yu'er mysteriously only planted a means of transportation called bicycles, and people could walk on their own by sitting on it and pedaling the pedals. Wang Dali didn't believe it when he heard it, the two-wheeled car couldn't even stand firmly there, let alone move again?

He saw that Yu'er was generous and dressed like ordinary people, and later learned that it was the maid ring of the county magistrate. Yu'er gave a large sum of money, and he himself didn't have too much money to put on, so he agreed, paying half of the deposit first, and then paying it off after the completion of the work.

Although Wang Dali felt that the money was very easy to earn this time, he was also conscientious and conscientious in his work, and he was not sloppy at all, plus the money given by Yu'er was several times the standard, and he watched Yu'er come to check every day, not like the county magistrate was hot-headed for a while, so Wang Dali handed over the rest of the work to the apprentice, and all his tools were moved home, and he went all out to make various parts painted on the drawings.

These carpentry tools, planing and sawing files, are not much different from the carpenter tools in the eighties, and the carpentry industry is not much different from the Song Dynasty and later generations.

For the manufacture of bicycles, Yu'er from time to time to give a little explanation, Wang Dali is a clever person, when Yu'er talked about the balance of the bicycle mainly depends on the human body coordination and direction handle to control, and gave the example of stepping on stilts, immediately understood, and from time to time to give Yuer some ideas, this discussion, there was a harvest.

According to Wang Dali, the pin of this chain does not need to be made of iron, and the requirements can be fully met with red jujube wood, but the chain can be fixed with thin iron pins at both ends of the jujube wood, and the ratchet part does not need to use copper sheets, because there are many stress points, and thin wood chips can be used to meet the requirements.

The king was busy for seven or eight days, and he was very excited to see the bicycle getting more and more beautiful.

When all the assembly is completed, what is displayed in front of him is a real bicycle, at least in Li Xiang's opinion, it looks the same as the bicycles of later generations.

Li Xiang looked at his work and asked, "Master, do you think this car can run?" ”

Wang Dali nodded affirmatively: "It's absolutely no problem to run!" He was so sure, and for good reason. Although Li Xiang repeatedly emphasized that this bicycle must be the first to be tested by himself, how could Wang Dali endure it, he had already tried it secretly, although some of the main parts had not yet been completed, but he was able to ride on it for a distance.

When he first learned to ride, Wang Dali was not used to it, but after a while he was able to ride around the yard. The formal test was carried out in Wang Dali's yard, Li Xiang first felt that the car was not as heavy as he imagined, about thirty kilograms, and then he rode up, kicked on the ground with both feet, the car borrowed force, and then slowly slid forward, but just stopped after sliding a short distance, obviously because the friction force of the bearing was too large.

Li Xiang stepped on the pedal and pedaled hard, and the car moved forward smoothly again. Li Xiang rode a few laps, and felt that in addition to the car being too heavy and pedaling hard, the shock absorption of the car was also a problem, and he suffered when the road was not very good. But being able to build a bicycle under these conditions, and it is made of wood, can be considered very successful. In fact

In fact, when the first bicycle came out in history, it was also made of wood, but there was no such complex transmission mechanism. It wasn't until many years later that rubber became popular, and there were solid rubber tires, and after many years, someone inadvertently appeared the squeezing phenomenon of soft water pipes, which came up with pneumatic rubber tires. When the first bicycle came out, it wasn't even as comfortable as the one in front of me. Still, it was a sensation at the time.

Yu'er and Xue'er were very surprised when they watched from the side, and Yu'er said happily: "Young master, it turns out that this car can really go by itself!" I'm going to try it too. As he spoke, he had already snatched the car.

Li Xiang was worried that Xue'er would be injured, so she was busy supporting her behind, but Yu'er adapted quickly, and when she reached the third lap, she could ride away by herself. She felt that it was fun, and she still refused to come down after five or six laps, but the car was extremely difficult to climb, and after a few laps Yu'er was exhausted, and obviously could not ride anymore, so she jumped off, her face flushed and panting.

The same goes for Cher, how could she not try it when she saw something so fresh.

When the bicycle can still be ridden, Li Xiang has to pay the rest of the salary, Wang Dali hurriedly said: "Don't worry, don't worry, this bicycle was finally completed, it should be celebrated, and some wine and food have been prepared in the next place, how about the county magistrate please go into the house and rest for a while?" Li Xiang was a little tired after being busy for a long time, so he entered the house with Xue'er and Yu'er.

During the banquet, Wang Dali laughed and asked tentatively: "Lord Li, there is a proposal below, I don't know if Lord Li is interested." ”

Li Xiang said: "Please speak." Wang Dali said: "Lord Li, Wang didn't know that this bicycle could walk like this before, but when I saw it today, it was really magical, Lord Li was extremely smart, and he could come up with such an ingenious work." I don't know if Master Li has ever thought that if this bicycle is mass-manufactured, it will be a way to make money. ”

He continued: "The production process of this car is complicated, and ordinary people naturally can't afford it, but there are many rich and noble families in the city, and if we can build a batch, it will definitely be in short supply." Besides, this is not far from Chengdu Mansion, where there are countless dignitaries, so just this bicycle makes me wait for endless financial resources. ”

Wang Dali became more and more excited, swallowed a mouthful of saliva, and continued with spittle: "Besides, when the business is good and the money is more profitable, we can improve the process and make a batch of cars of different sizes, wood and color, of course, the price is also different, and we can even make some cars with iron parts." I wonder what Master Li thinks? ”

Li Xiang was dumbfounded. Talented! What a business genius you are! Li Xiang really wanted to jump up and pat Wang Dali on the shoulder to praise him, but he still held back. "Oh, this is cooperating with Boss Wang for batch production, the county is not mentally prepared yet, besides" Speaking of this, Li Xiang stopped and deliberately hesitated. (To be continued.) )
