As soon as he reminded him, Qin Lao remembered his original intention of seeing Shen Qingqian.

So he hurriedly took out the drawings and beckoned Shen Qingqian to lean over, "Look at it, your eldest brother said that this thing can be moved, right?" But the parts that connect these two things are too small for us to do. ”

Shen Qingqian took a closer look to know what he was talking about, it was actually a screw.

"Can't you do it with the wax method?" Shen Qingqian asked suspiciously.

The wax method is the lost wax method, also known as the "investment mold method", which is a fine casting method for bronze and other metal objects.

Qin Lao was surprised: "You even know this? ”

"I saw it in a book." Shen Qing looked at him with a shallow face and said.

"What book? Where did it come from? Qin Lao's eyes were shining, and his face was full of "Tell me".

Shen Qingqian had a headache, why does this old man always have the ability to deviate from the topic? Aren't you talking about screws now? How did his attention go back to books?

Shen Xiao was also very helpless, so he had to open his mouth again to remind, "Old Qin, my sixth sister asked you, can you do it with the wax method?" ”

Qin Lao really immediately put aside the problem of the book, and said with a serious face: "It can be done with the wax method, but that is too troublesome, and you need more tough and hardness materials for this thing, and we don't have it." ”

Shen Qingqian knew that he was talking about steel, but this world has not, and the smelting technology of copper and iron has not yet developed to its peak, let alone steel.

And the trouble he said wasn't for her. Nowadays, there is no assembly line operation in this world, especially in the technology industry, and the phenomenon of self-cherishing is particularly serious.

"Actually, no, the existing copper and iron can also be made, but as you said, the wear and tear will be relatively large, so we need to do more, and replace it if it is broken." Shen Qingqian said his thoughts.

Qin Lao tugged at his beard and pondered, and then nodded after a while, "You're right, this is indeed a solution, but it still can't solve the problem." ”

Shen Qingqian asked uncertainly, "Old Qin, do you want to make my paintings in large quantities?" ”

If you're only making a few dozens, there's really no need to ask this question.

"That's natural, you can greatly improve the progress of land reclamation, even if the imperial court does not agree, our general will be happy to promote these two new agricultural tools in northern Hubei." Qin Lao said it as a matter of course.

He directly defined Shen Qing's paintings as new agricultural tools, which shows the recognition of these two agricultural tools.

Shen Qingqian heard him say this, so he said: "Of course there is a way, but I'm afraid that Old Qin you won't agree." ”

"What's the solution? As long as I can do it, 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, let different people be responsible for different steps, dozens of people and hundreds of people do it together, and the speed will naturally be raised." ”

Each person is responsible for only one step, that is, only doing the same thing, so that habits are quickly formed, practice makes perfect, and the speed of production naturally increases with the proficiency of the workers.

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

There are rules in their profession, and they can't pass on some special techniques.

In fact, although it has been mentioned in some books, not many people know about waxing, and even fewer can use waxing well.

That's why he was so surprised that Shen Qingqian actually knew the wax method.

"Old Qin is unwilling?" Shen Qingqian asked rhetorically.
