The progress of the bearing is also smooth, three days later, Su Su sent three finished products.

Su Su put the three bearings on the table: "Sir, take a look, according to the size measurement method you gave, the largest is that the inner ring is seven centimeters, and the smallest inner ring is one and a half centimeters. We use the method of mounting the inner ring to prop up.

It is to first fix the outer ring and the steel ball with black glue, make the inner ring smaller, place it after it is red, and then use the steel mold to prop it up. In this way, we can continue to make bigger ones, and we can do them very simply. But the small can't do the smaller. Because the inner ring is enlarged, it cannot be disassembled after combination. In the later stage, we are going to develop a detachable and replaceable steel ball, just as Mr. said, the sleeve can be made into a composition. In my opinion, the most likely part of this bearing to break is the steel ball. ”

"You're right, that's the most economical" Xiang Bei said and scrolled, very satisfied with the product: "It's very good, it's very smooth." No matter how small it is, don't do it, and the extensive machinery of this world will not be used. This polish is good, better than what the machine does. Do you have an estimate of the yield?"

"If there are five low-level craftsmen, you can make more than twenty per day. It's just that the fixed sleeve on this steel ball is not easy to do. ”

"Quite a bit, yes. I asked you to set up a research and development team, do you have eyebrows?"

"I've only used one of our artisans to work with me on the new thing. I didn't choose the others, and I'm going to look for them later. ”

"Don't worry, you must find something reliable. It's also essential that you make me one more thing. ”

"Sir, please. ”

"Screws, screws of all sizes. What is it, you come over and I'll show you. ”

Xiang Bei told him specifically what screws and nuts are. After the talk, I asked him how he was, and how could he do it?

Su Su said that if it was refined, it would be very easy. But in terms of function, this thing needs a very large amount, and it is used for the same purpose as iron nails. From the beginning, look for ways that can be processed by ordinary people. The main difficulty is on this thread.

Xiang Bei was satisfied, Su Su was really smart, and he knew what to do as soon as he said it.

He told Susu: "Start with the tool and make a tool that can carve threads." Screws don't need to be kept secret, it's the tool that needs to be kept secret. I'll give you an idea, I don't know how to make screws, but I've worked as a plumber, and the pipe dewires use a dewired machine, and the screws should also work.

The hardness of steel is not the same between them. Use the hardest steel to make teeth according to the size of the screws, we call them plate teeth, how you like to call them. The plate teeth can be rotated tightly to get rid of the wire. If this had already been there, the heating wouldn't have been so troublesome.

Of course, this is just to make the outer tooth, to make the inner tooth of the nut, to the other way around, in fact, it is a simpler object, just use a tapper. Drill holes in the iron plate, then tap the wire with a tapper, get it done, and then cut it into a nut. I worked in a machine factory, I am more familiar with this, and I will draw it to you. There are also wrenches that have to be made, different screws use different wrenches, this is not difficult, you will understand as soon as I say it. ”

Xiang Bei said as he began to paint. Su Su watched intently, and with a chuckle on his face, Chu Pity next to him did not look at his picture, but looked at Xiang Bei at work.

It wasn't until Xiang Bei finished doing it that she found Chu's pitiful gaze and asked her if she thought the man who worked seriously was particularly handsome?

Chu pouted pitifully: "Be less narcissistic, you can't be handsome no matter what you do." If you have the chance, you can really think of your hometown and see what a magical world it is. ”

"No, if you don't look, I can pretend to be a scientist here. If you look at it, you will find that everyone understands what I know, and I'm just a sling, which is not good. ”

Xiang Bei felt that it was better for her not to see it. Give the picture to Su Su and ask her if she has any questions?

Su Su said no problem, they all understand the painting so clearly, how can there be a problem. Ask yourself: Is it okay to do it now?

Xiang Bei waved his hand: "Go ahead." ”

Su Su left, and Chu asked Xiang Bei with pity: "Didn't you say that you didn't participate in the provision of the specific production method, why did you draw it in such detail this time?"

"I just fell into the professional range, I can't help it. Princess, do you think this bearing is fun?"

"What's so funny, Xiao Lili may like it very much, roll, roll. ”

"I'll use this smallest, let's make you something to play with, it's okay to decompress. ”

"What?"

"Fidget spinner, let's go, go to the backyard workshop. ”

Xiang Bei and Chu came to the workshop, and a group of workers who were welding radiators immediately knelt down and bowed. Chu took pity on them all to get up, and there was no need to kneel and worship here in the future, wasting time in vain.

"Thank you, Princess" and the group got up one after another, and Chu asked Xiang Bei how to get a fidget spinner?

Xiang Bei looked around: "I'll make you a three-leaf gyroscope, you bring me the hot melt paste, and take a small steel plate." ”

Chu is very diligent, he gives him what he wants, and whoever understands technology is the boss.

Xiang Bei looked at it: "I can't cut the steel plate either, so I will waste some hot melt paste and melt the shape I want directly." In fact, it is very simple, after making the shape, put this bearing in the middle and fuse it with the outer ring of the bearing. Then the inner circle is filled, and the indentation is made to place the fingers, which is a very simple gadget. ”

Xiang Bei used hot melt paste on the steel plate to melt the shape he thought was cool, and then put the small bearing into it and melted it hot. Finally, stuff some broken iron in the middle, melt it in the middle, find a round stick, and press out the depression where the finger is placed. After it is done, it is handed over to the worker to polish the shiny tile, put it on the finger and spin it. The four fingers alternate constantly, and the top spiral rotates back and forth between the fingertips, as if dancing.

Chu looked curious: "It's really fun, give it to me." ”

Chu took it with pity, but after trying it, it fell directly to the ground.

Xiang Bei told her not to worry, this needs to be practiced, first practice with one finger, and then think about changing fingers.

Chu nodded pitifully: "Old Xiang is reliable, you continue to cut here." I'll go to Susu and make another bearing, and you continue to do it. The next one is mine, this one will be given to the small grain, and it is more important to coax the child. ”

Chu ran out after saying that, leaving Xiang Bei alone and depressed, isn't he looking for trouble.

He shouted at Chu with pity: "Let Su Su do two, the small grains are there, then Doudou will not be sad, how to say that it is also my apprentice's sister." ”

"I see. Chu Pian shouted while running, and did not stop, not ladylike at all.

Such a scene made the workers laugh when they saw it. Xiang Bei felt quite faceless, no matter how he said that he was also a master, how could he become a child toy. But I haven't been down the workshop for a long time, and I feel quite good.
