Chapter 115 Screws

After being reminded by him, Mr. Qin remembered his original intention of meeting Shen Qingqian.

So he quickly took out the drawings and beckoned Shen Qingqian to come over, "Look, your brother said this thing is movable, right? But the parts connecting the two things are too small, and we can't make it."

Shen Qingqian took a closer look and realized what he was talking about. It was actually a screw.

"Can't it be done using the waxing method?" Shen Qingqian asked doubtfully.

The lost wax method is the lost wax method, also called the "investment method". It is a precision casting method for metal objects such as bronze.

Mr. Qin said in surprise: "You even know this?"

"I saw it in a book." Shen Qingqian looked at him without changing her expression.

"What book? Where did it come from?" Mr. Qin's eyes were shining, and "Tell me quickly" was written all over his face.

Shen Qingqian had a headache. Why did this old man always have the ability to change the topic? Aren't we talking about screws now? Why did his attention turn to the book again?

Shen Xiao was helpless and had to remind him again, "Mr. Qin, my sixth sister is asking you, can you use the waxing method?"

Sure enough, Mr. Qin immediately put aside the question of the book and said with a serious face: "It can be done using the waxing method, but that would be too troublesome, and you need more tough and hard materials, which we don't have."

Shen Qingqian knew that he was talking about steel. In this world, copper and iron smelting technology had not yet reached its peak, let alone steel.

And the trouble he was talking about wasn't what she was talking about. There is no assembly line operation in today's world, especially in the technology industry. The phenomenon of self-preservation is particularly serious. You have to do everything by yourself from beginning to end, which is of course troublesome.

"Actually, no need. Existing copper and iron can also be used. It's just like you said, the wear will be greater when it is made, so we have to make more. If it breaks, just replace it." Shen Qingqian said her thoughts .

Mr. Qin pulled his beard and thought, and then nodded after a while, "You are right, this is indeed a solution, but it still cannot solve the problem."

Shen Qingqian asked uncertainly, "Mr. Qin, do you want to mass-produce the things I drew?"

If you only make a few or dozens of pieces, there is really no need to ask this question.

"That's natural. This thing of yours can greatly improve the progress of land reclamation. Even if the court disagrees, our general will be happy to promote these two new agricultural tools in northern Hubei." Mr. Qin said matter-of-factly.

He directly defined Shen Qingqian's paintings as new farm tools, which shows his recognition of these two farm tools.

Shen Qingqian heard what he said and said, "Of course there is a way, but I'm afraid Mr. Qin you won't agree."

"What method? As long as it can be done, what can't I agree with?"

Shen Qingqian looked at him quietly and said: "As long as the steps of the waxing method are clearly divided and different people are responsible for different steps, if dozens or hundreds of people do it together, the speed will naturally increase."

Each person is only responsible for one step, that is, only doing the same thing. In this way, habits can be formed quickly, practice makes perfect, and the production speed will naturally increase with the proficiency of the workers.

"You mean you want me to hand over the waxing method to dozens or hundreds of people?" Mr. Qin's brows immediately furrowed.

There are rules in their profession and they cannot pass on some special techniques.

In fact, although some people have mentioned it in some books, not many people know the waxing method, and even fewer people can use the waxing method well.

That's why he was so surprised that Shen Qingqian knew how to remove wax.

"Mr. Qin is unwilling?" Shen Qingqian asked.
