Chapter 137 Parts that cannot be made
After being reminded by him, Old Qin remembered the original intention of meeting Shen Qingqian.
So he quickly took out the blueprint and beckoned Shen Qingqian to come over, "Take a look, your eldest brother said this thing can move, right? But the parts connecting the two things are too small, 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, also known as the "investment casting method", is a fine casting method for bronze and other metal objects.
Qin Lao was surprised and said: "You even know this"
"I saw it in a book." Shen Qingqian looked at him calmly.
"What book is that and where did it come from?" Old Qin's eyes sparkled, and his face was full of "Tell me quickly".
Shen Qingqian had a headache. How come this old man always had the ability to divert the topic? Aren't we talking about screws now? Why is his attention on the book again?
Shen Xiao was also helpless and had to open his mouth to remind again, "Mr. Qin, my sixth sister asks you, can it be done using the wax method?"
As expected, Old Qin immediately put aside the question about the book and said seriously, "It can be done using the wax method, but that's too troublesome. Besides, your thing requires a more flexible and hard material, which we don't have."
Shen Qingqian knew that he was talking about steel. This world didn't have it yet. The smelting technology of copper and iron had not yet developed to its peak, let alone steel.
And the trouble he was talking about wasn't really her problem. The world didn't have assembly lines anymore, especially in the tech industry, where the tendency to hoard things was rampant. People had to do everything themselves, from start to finish, which was, of course, a hassle.
"Actually, there's no need. The existing copper and iron can also be used. But as you said, it will wear out more, so we have to make more. If it breaks, we can just replace this small part." Shen Qingqian expressed his thoughts.
Old Qin pulled at his beard and thought for a while before nodding, "You're right, this is indeed a solution, but it still doesn't solve the problem."
Shen Qingqian asked uncertainly, "Mr. Qin, do you want to mass-produce the things I draw?"
If you are only making a few dozen, there is really no need to ask this question.
"Of course. Your thing can greatly speed up 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." Old Qin said as a matter of course.
He directly defined Shen Qingqian's paintings as new agricultural tools, which shows his recognition of these two agricultural tools.
After hearing what he said, Shen Qingqian said, "Of course there is a way, but I'm afraid you, Mr. Qin, won't agree."
"As long as it can be done, there is nothing I cannot agree to."
Shen Qingqian looked at him quietly and said, "We just need to clearly divide the steps of the waxing method and let different people be responsible for different steps. If dozens or even hundreds of people work together, the speed will naturally increase."
Each person is only responsible for one step, that is, only doing the same thing, so that habits can be formed quickly, practice makes perfect, and production speed will naturally increase with the workers' proficiency.
"You mean you want me to teach the wax-making method to dozens or hundreds of people?" Old Qin frowned immediately.
There are rules in their industry, and some special techniques cannot be passed on.
In fact, although it has been mentioned in some books, not many people know about the waxing method, and even fewer people can use it well.
That's why he was so surprised that Shen Qingqian actually knew the waxing method.
"Mr. Qin is unwilling?" Shen Qingqian asked back.
