Twenty days later, the ordnance production workshop of the Ordnance Superintendent has changed dramatically. And many craftsmen here have also started to work on an assembly line, and many workers have also done some simple things on the assembly line, such as simply sorting out some tools. There is also inserting the arrows of those crossbow arrows into the shaft, and then some of the processes have to be done like this. At present, this assembly line is just a material for installing some crossbow arrows, and nothing else has been made. And this assembly line is only a few tens of meters, and it is not as long as those assembly lines in later generations. Even the top of this assembly line is just a cloth bag made of canvas, not the belt of later generations. But this Qian Jiao has brought about a substantial change.

"Chen Langzhong, this thing is really a god. In the past, every time the arrows were installed, the craftsmen had to install them one by one and then dip them in glue. But now this assembly line can actually install arrows for the first few people, glue them to the middle ones, and the last few people are responsible for cleaning up these arrows. What used to be a very time-consuming thing can now be increased by more than ten times the speed, which is a very huge thing. Ever since Chen Langzhong invented this pulley crossbow, arrows have been raining down, and the consumption of arrows is really too much. Now that we have this thing, the next arrow production is much faster. Yang San said.

But Chen Fei shook his head and said, "This is nothing, I am very disappointed with this steam engine!" ”

Chen Fei said that he was disappointed with this steam engine, but this is true. The steam engine he used was actually a model of the early 20th century, and it should have been at least 200 revolutions per minute in terms of rotational speed. But this steam engine is too bad, and the speed is only 30 revolutions per minute. With such a slow speed, where can it be used as a machine tool! Originally, Chen Fei still wanted to use it to make various processing machines, but it was such a speed. Don't count on it at all.

"Chen Langzhong, after we made the first one, we all have experience. As for the next, we should be doing better and better, and we should be able to have seventy or eighty turns, right? And the new machine, which has a lot of power, can be used as a machine for splitting wood! Master Liu said.

According to Chen Fei's previous design, these steam engines have many functions. It can not only be used as the driving force of this assembly line cloth belt, but also has other functions. For example, it is used as a chopping firewood and processing firewood. If you add a round saw blade to the bearing of a steam engine. It can be used as a sawmill, and the processing of wood in this way has improved dramatically.

During this period, wood was cut and processed by manpower. This method is very laborious and time-consuming. Chen Fei also wants to make this sawmill and then make wood processing a lot of men. But these things only made a steam engine with a speed of only 30 revolutions per minute, which is simply too slow. And the power of this steam engine is not enough, it is simply not enough to process wood. As for chopping, that's not to mention.

However, Chen Fei then asked those high-level craftsmen to make the new steam engine. This time, Chen Fei gave them a technical standard of 60 revolutions per minute, and the strength was sufficient. Such a steam engine Chen Fei is naturally very useful, not only can be used as the driving force of the assembly line, but also can be used as a chopping force. There are also important props for sawing wood. In this way, more than 60 percent of the time can be saved in processing wood. At that time, it will only be necessary to go through some so-called grinding of the wood, which will be enough to become an arrow shaft. With a sawmill, it is equivalent to saving the most time-consuming and physically demanding working time. Save more than 60% of the time for processing wood. Then you can save more craftsmen to make the shaft, so that it is not a one-to-two effect, but in general, the speed of producing an arrow is increased by more than ten times.

"And. You can use this steam engine and put a big whetstone on it. As long as the whetstone can be installed, then the next horizontal knife and spear sharpening can increase the speed a lot. Even ordinary arrows can be sharpened quickly, and then they are qualified. ”

After Chen Fei's observation during this period of time, he found that if he wanted to make a knife during this period, or use sharpness as a weapon to kill the enemy, in fact, the most time-consuming thing was in sharpening the knife. It's not difficult to make a blank, but it's not easy to turn it into a sharp knife. In ancient times, knife sharpening was made by manpower, which was very inefficient. But with this steam engine equipped with a whetstone, it is equivalent to increasing the speed of sharpening knives many times, and the time it took to sharpen one knife in the past can now be completely improved to sharpen ten knives. This is also the benefit of machinery, which can improve efficiency.

"Chen Langzhong, with this steam engine, then our processing speed has increased a lot. Originally, I thought that there were 200,000 pulley crossbows and 10 million crossbow arrows, but I thought I couldn't finish it. But now, I think we can go above and beyond! Chen Langzhong is really a god! Yang San said.

Originally, Yang San thought that he would not be able to complete the task of 200,000 pulley crossbows and 10 million crossbow arrows, but now looking at this situation, it is completely overfulfilled. In just a few days, the output of the past month was produced, and this Yang San didn't dare to think about it at all. If the next steam engine with a whetstone can be put into use, I am afraid that the arrows will be sharpened very quickly. It doesn't take a few seconds for a skilled worker to polish an arrow, whereas it used to take at least a few minutes to grind an arrow, and this is the gap.

Therefore, 10 million crossbow arrows is not a problem for Yang San at all. On the contrary, he hoped that Li Shimin would give more tasks, so that he might be more credited.

"Chen Langzhong, in about five days, we will be able to make a second steam engine. After all, we have experience, and we should be able to complete it in ten days this time. If it weren't for Chen Langzhong's strong support, we wouldn't have been able to figure it out! We've been working overtime for the past few days, working eight hours a day! Only in this way can we live up to the good treatment given to us by Chen Langzhong. Master Liu said.

The steam engine was built quickly, but it was based on the fact that these senior craftsmen worked sixteen hours a day, and only rested for six hours while sleeping, and two hours were used to arrange and study with Chen Fei. It can be said that the day is all scheduled. That's why it has such a quick effect. (To be continued......)
