As for the two words of a gun, the most difficult thing to make is actually two parts, the first one is a bullet and the second one is the barrel.
Both of these things have extremely high requirements for materials and processes. For example, the high-strength alloys and launching drugs required to make shell shells are something that cannot be provided by this era.
Although Lin Xu is a hard-core science and technology man who is proficient in materials and chemistry, he is hard to cook without rice. Due to the limitations of the times, a small bullet cannot be made by him!
However, he still has a way to solve this problem, which is to create a long-barrel gun and use black gunpowder to fire solid projectiles. Although it is less powerful, it can also be used.
But, the barrel is inevitable no matter what!
When making gun barrels, common mold casting processes cannot be used, because the barrels made in this way will inevitably appear bubbles, which will easily explode, which will cause great safety hazards to the user.
In order to ensure quality, cold forging must be used for manufacturing.
Simply put, it is to hollow out a solid steel pipe with a drill bit.
If you want to hollow out a solid steel pipe with a drill bit, it is obviously not possible to rely on manpower alone. Even Zhang Lie does not have that much force. Moreover, if you use manpower, the accuracy cannot be guaranteed!
In short, if you want to create the barrel, you must use a machine tool!
During the two months he spent in Hangzhou Prefecture, he would draw some parts of basic machine tools as soon as he had time. Over time, he finally drew out several commonly used basic machine tools drawings.
Of course, the machine tools he designed are far from comparable to those of the high-precision machines in his previous lives. Even the beggar version is not considered a beggar version, and can only be regarded as an extremely simplified version!
This is really a last resort, because it is not enough to produce a high-precision machine tool, but it is the result of the blooming of many basic disciplines!
In addition, he has no electricity to provide power, so he can only borrow water energy.
Lin Xu was too busy and didn't have so much time and energy to tinker with the machine tools in detail. Besides, he just had theoretical knowledge and his actual hands-on ability was actually very average. When the drawings were drawn, he had to find someone with strong hands-on ability to implement it.
Therefore, after drawing these drawings, Lin Xu first showed them to his brother-in-law Zhang Lie.
Machine tools are mainly made of steel, and Zhang Lie is indeed a good at steel smelting, and he is also very interested in this industry. It is just right to find him to implement it!
However, Zhang Lie also has a big disadvantage, that is, he is unwilling to use his brain and only likes to do things!
After simply reading these drawings, Zhang Lie immediately became overwhelmed and had no intention of conducting in-depth research.
So, Lin Xu targeted Gensheng again!
Although Gensheng is a carpenter, he usually makes tables, chairs, spinning wheels, etc. and has similarities with making machine tools.
In addition, according to his observation, Gensheng has extremely strong comprehension and hands-on ability, and he is also a person who is very willing to learn and study!
Moreover, one more important point is that he knows the roots and the bottom of his life. This is a completely reliable person!
Such an important technology for machine tool manufacturing, you must definitely teach people you can trust!
Originally, when he came back from the county government this time, he wanted to hand over these drawings to Gensheng and let him study and study first. As a result, Gensheng was seriously injured by Liu Zhuzi!
Therefore, he delayed it for a few more days. This chapter has been completed!
