I am a primitive

When Han Cheng saw that Bai Xuemei had made a move, he automatically abdicated to Xian.

After Bai Xuemei tied it up, he pulled the seven-strand fiber with his hands and walked to the shelf that was just set up.

A fiber is stuffed into a corresponding hole, and then plugged with a small wooden post.

In this way, the fiber is fixed.

Doing things one by one, after a while, the seven fibers were fixed by Han Cheng.

After doing this, Han Chengcheng came to the side of the spinning machine in the experiment, held the handle with his hand and started spinning.

As he shook, the seven fibers tied to the loom began to rotate with it.

Because several fibers are fixed by the other end this time, the force that goes up with the rotation of the spinning machine does not escape, so these scattered fibers are synthesized together soon and become a qualified yarn.

Han Cheng showed a satisfied smile, and Bai Xuemei's face was also amazed.

Because the hand-operated spinning machine created by Han Cheng can spin seven yarns at a time, which is much faster than spinning with a spinning top!

Brother Cheng is really too smart!

There is a kind of handsome called handsome but not more than three seconds.

This kind of thing is perfect for Han Cheng.

As soon as one problem was solved, another one followed.

The problem is how to wind the thread that is well wound to the corresponding stick.

When the yarn is combined with the spinning top, it is manually wound on the long handle on the top of the spinning top.

Han Cheng stood here watching for a while, and found that there was no other way to use the experimental spinning machine he made except to wind it manually.

Han Cheng pulled out the cork that fixed a piece of yarn, and then took it to the side of the simple spinning machine with his hand, and wound it round and round on the corresponding wooden post with his hand.

After wrapping up the good-strength section, I tied a knot and tied it here to prevent it from opening.

Then followed by the remaining six...

After finally finishing these things, Han Cheng encountered another situation.

This situation is that the length of the fiber is limited. After the previous winding, the existing fiber is not long enough, and new fibers need to be inserted into it to make it longer.

When adding new fibers into it, there is a necessary condition, which is the need to rub the yarn to make it rotate vigorously.

When the force on the rope passes through the junction of the new and old fibers, the old and new fibers will be connected together and become a whole.

In this process, one hand is required to pull the yarn, and the other hand is responsible for turning the circle.

Under such circumstances, one hand can only be responsible for one yarn at a time, but there are seven threads on the spinning machine made by Han Cheng!

Calculated in this way, at least four people need to work here together to ensure that this simple machine works normally and spins.

This is obviously extremely uneconomical.

Four people just use the spinning top to spin, and the efficiency is higher than this.

After realizing this problem, Han Cheng once again stopped his work and fell into a new round of thinking...

When it was noon, there was a clanging sound again.

After a while of operation, the more frustrated and courageous, Han Cheng, who was working hard on the spinning machine, put down the tools in his hand.

At this time, this simple spinning machine has changed again.

On the whole, there is not much change. The biggest change is that the original seven small wooden pillars have become one small wooden pillar now.

After pondering for a while and being busy for a long time, the frame that fixed the fiber that took almost two days to manufacture was abandoned and did useless work.

was thrown aside.

Han Cheng shook the experimental spinning machine for a while, feeling its operation.

Han Cheng originally wanted to spin a piece of yarn by himself to test the effect, but after seeing Bai Xuemei who came to deliver food to him with a rice bowl, Han Cheng stopped this embarrassing idea.

He took the rice bowl from Bai Xuemei, took a bite, and motioned Bai Xuemei to try the spinning effect of this thing.

These days, Bai Xuemei has been running here a lot to watch Han Cheng make this thing. Now, she already knows what Han Cheng wants to do and how this thing is used.

After receiving Han Cheng's signal, Bai Xuemei stepped forward to start the experiment.

She tied some fibers to the slender wooden post in the middle, and then held the handle with her right hand and started to shake it, while pinching the fibers with her left hand, replacing the eliminated wooden frame to fix the fibers.

After a while like this, Bai Xuemei pinched the section of fiber between the spinning machine and the spinning machine with her hands, and the fiber was already wrapped.

Holding the fibrous hand, Bai Xuemei moved towards her arms, and pulled the line that was originally parallel to the wooden post to be perpendicular to the wooden post.

Then the right hand shook accordingly, and then this stretched thread was wrapped around the wooden post.

After the winding is completed, the fiber is held on the top of the wooden column to fix it, and then the left hand holding the fiber is moved back a bit, and the fiber is pulled parallel to the wooden column again, and a new round of strength is started...

-------------Chapter Dividing Line---------------

Facts have proved that the saying that one bite cannot make a fat man is quite true.

Of course, except for those long worms that swallow prey thicker than their own body, causing their body to grow larger and bloated at a speed visible to the naked eye, and directly become a big fat man.

Han Cheng now deeply understands the wisdom brought by this common saying,

When he was trying to make a spinning machine at the beginning, he thought about spinning as many threads as possible at a time to greatly improve work efficiency.

But after some experiments, it was found that under the current technical conditions, this would not work at all.

In the end, all the redundant wooden pillars were removed, leaving only the middle one.

Looking at the simple spinning machine that has already spun a lot of yarn under the operation of Bai Xuemei, Han Cheng couldn't help but smile on his face.

From the current point of view, it seems that I have figured out a lot of things and found the basic principles.

On the basis of the current simple spinning machine, and constantly solve and adjust the problems that arise, Han Cheng believes that he will be able to make a useful spinning machine.

When the mood is good, the appetite is good.

Han Cheng ate two and a half bowls of vegetable soup and dried millet rice before he stopped eating.

"Let's go, don't study it for now, go back and have a good sleep, and then do it after getting up."
