On the second day, Zhang San didn't have anything to do, so he went to the group that studied the machinery to see their progress, and when they came here, they had already made a wooden model of the machine on Zhang San's drawings. Pen % fun % Pavilion www.biquge.info

When Zhang San arrived, they were testing the machine, watching Liu Qiao step on the foot pedal, the foot pedal drove the flywheel to rotate, and it was driven to the top table through a belt made of animal tendons, and there was a fixed hinge on the table with a grinding wheel inlaid with a grinding wheel rotating rapidly.

Liu Qiao carefully put a square piece of wood close to the grinding wheel, and it was ground into a ball after a while. When the machine stopped, everyone was encouraged. Zhang San was also very happy and leaned over to take a closer look.

At present, there is no ability to process complex gears, so Zhang San tries to minimize the use of gears, this animal tendon is an important material for making bowstrings, so it is better to buy. A few strands of tendon that are churned together are no worse to use than a rubber band.

Now that the principle is done and the experiment is successful, then the next step can be to start production, as for the question of how to increase the speed, it is not enough to add a flywheel size in the middle.

Zhang San remembered that the flywheels of the old-fashioned sewing machines at home were all cast in pig iron, and it was estimated that this kind of pedal power would take a long time in the future, so Zhang San decided to make a set of molds to produce this.

Now that the grinding stone is made, the circular saw is simple, the sawtooth needs steel, and the other parts are still like this, but the circular saw needs a greater speed and greater resistance, but fortunately it is just a simple little thing. Zhang San decided to give it a try, if it didn't work, it would be a big deal to change to a double pedaling or bicycle power.

The size of the flywheel needs to be finalized here, and Zhang San doesn't remember how big it used to be, so he just casually set it at two feet in diameter. The size was determined, and then the styles of other accessories were also made according to Zhang San's drawings to make wooden patterns and then taken to the blacksmith to make molds.

The blacksmith has already had several experiences in making iron molds, and it is guaranteed that it can be done in two or three days, and now with a stone grinder and a circular saw, the conditions for making all kinds of chess pieces and chess boxes are available.

And the efficiency will be much higher than before, the increase in efficiency is the increase in profits, and with the experience of making these two machines, the production of lighters will no longer be a problem in the future.

Zhang San asked them to continue their research, and when they returned to the front yard, Zhang San saw Zhang Yuanba playing with his new hammer. After Zhang San agreed last time, Zhang Yuanba went to the blacksmith to supervise the work and made this pair of hammers, each weighing 100 catties, and the dance was very imposing.

With this pair of hammers, no one in the yard dares to fight with him for weapons, and now only Yang Tai can treat him, since the children moved away yesterday, the front yard has been a lot empty, Yang Tai and they are burdened with teaching tasks, so the courtyard has become Zhang Yuanba's world.

Zhang San looked at it for a while, and felt that Zhang Yuanba's double hammer dance was impenetrable, and he probably couldn't catch a hammer when he went up, it seems that the gap between his third-rate and his second-rate is still obvious.

Zhang Sanzheng watched it with relish, and the monkey came over and said, "Third brother, I just got the news, and Wu Slip, the fast hand in Xicheng, has slipped away." ”

Zhang San was furious when he heard this, this Kuaishou Wu has committed several major crimes, not only organizing thieves to steal passers-by on the street, but also blocking the road and robbing, extorting and doing all kinds of evil. It is said that there was a rich man in Xicheng who scolded him for stealing in order to catch him stealing, and he actually took advantage of the night to destroy people's houses.

And recruiting orphans to steal things, it should be disobedient and he disposes of many children. He also trafficked girls to brothels, how angry was such a wicked person who ran away.

"Have you ever sent someone to follow?"

The monkey nodded and said: "This Kuaishou Wu seems to have gotten the news in advance, and he left as soon as he set out, but fortunately, the third brother let these people keep an eye on them, and I sent two clever ones to stare at the front and back doors." ”

"That Kuaishou Wu went out from the back door in the morning, followed a courtyard along the inner city wall, and never came out after that, it is estimated that it is one of his refuge dens."

Zhang San nodded and said, "You sent someone to keep an eye on him, and we will deal with him at night." The others who have not been brought to justice must also be kept an eye on and strive for not one to be spared. ”

The monkey took the order. Zhang San went to the school again, Yang Tai and they were all here, even Gan Xingtai was here to watch the children practice boxing, and from time to time they went up to guide them, and Liu Yunle and he were also here to facilitate Yang Tai's guidance.

Zhang San asked Yang Tai if he had encountered any problems and whether these children were obedient. Yang Tai said embarrassedly: "Only a few people such as his son left their parents for the first time are a little recognized, but they are all fine." ”

Zhang San turned around and saw little Lu Bu, called him over and asked, "Lu Bu, how are you studying these days?" Can you follow the class? Has anyone bullied you? ”

Lu Bu shook his little head and shouted timidly: "Brother, it's all right, everyone is good, teachers are good, classmates are good, Lu Bu is working hard to write his name now." ”

Zhang San touched his head and said, "Well, you have to work hard, how is Qingqiu doing." ”

Lu Bu nodded and said, "My sister has been fine for a long time, and she is now in the class." Do you want me to call her? ”

Zhang San smiled: "No need, you can go to class well." ”

After a class, Zhang San called everyone over, told them about Xicheng Kuaishou Wu, arranged for them to act at night, and asked everyone to get back all his ill-gotten gains when they repaired him, so that they could use it to help others.

Everyone nodded excitedly after hearing this, Zhang San went on to say that everyone should wait a little at night, Zhang San estimated that the person who reported to him might go to him tonight, so it was best to wait until that guy also came over to repair it together.

It wasn't until it was slightly dark that everyone followed the monkey out with a small bag on their backs, and Zhang San sat in the yard and waited.

Yang Tai and the others first went to an alley where Kuaishou Wu was hiding, changed their clothes, took out the extra things on their bodies, and one person held a waist knife, and Le He was responsible for watching things and answering. Everyone waited quietly until about nine o'clock, when the monkey came to summon another person in the courtyard who had just entered the courtyard.

Everyone was impatient to wait, covered their faces and walked out of the alley, went straight to the yard, and didn't say much when they arrived, kicked open the door of the courtyard, and the two people in the house were still sitting and talking, but they didn't react, Yang Tai and Gan Xingtai had already kicked the two of them down and put the knife on their necks.

Gan Xingtai is still more experienced in these things, and it didn't take much effort to ask where the money was hidden, everyone went to the house under the bed to pick up the floating soil, and sure enough, two boxes were proposed, Yang Tai signaled Zhang Yuanba and Liu Yun to carry the box to find Lehe first, and he and Gan Xingtai broke the two hands and feet and tied them to the ground in the house.

A few people left quickly, changed their clothes in the alley, poured the contents of the box into the box that had been prepared long ago, and Zhang Yuanba and Lehe carried them to the north of the city.
