I am a primitive

One side of the big wheel is equipped with a handle that can be shaken by hand, and on the outermost circle of the wheel on the other side, there is a slender wooden post for hanging a line.

Han Cheng held the wooden handle and shook it a few times, which was quite light.

"Come here and see how it is now, is there anything better?"

Han Cheng said this to Bai Xuemei who was not far away.

Hearing Han Cheng's greeting, Bai Xuemei, who had been paying attention to the situation here, immediately put down the spinning top in her hand, walked to Han Cheng's side, and skillfully tied the fiber to the modified spinning top. On the top of the small wooden post specially used to bind fibers on the spinning frame.

Then squatting on the side of the spinning machine, holding the fiber in one hand, holding the handle of the spinning machine with the other hand and starting to shake, trying to weave cloth with the newly modified spinning machine.

But just at the beginning, some problems have already been discovered.

For example, the handle on the spinning machine and the wooden post on the spinning machine are located on both sides of the big wheel.

If a person wants to work with this spinning machine, two hands need to be on both sides of the spinning machine.

That is to say, human beings are in a vertical relationship with the rotating wheels of the spinning machine.

In the beginning, when the spinning machine didn’t have the big wheels, there was no problem with this. In such a posture, you can still spin without feeling uncomfortable or awkward.

But now it’s no longer possible. Now the wheels have become much larger, and human arms are limited. Under such circumstances, in order to ensure that her body will not rub against the wheels and allow the wheels to rotate normally, Bai Xuemei took the fiber That hand can't extend too much outside.

Not being able to move out too much means that the distance between the hand and the wheel is short, and it is impossible to spin too much yarn at once.

Moreover, the reason why Han Cheng made such a big wheel was because he wondered if the spinning machine's wheel would become larger and the speed would become faster.

Now it seems that this is impossible.

Bai Xuemei shakes it with the wooden handle in her hand, and shakes it once while holding the wooden handle in her hand, and the big wheel will turn around accordingly.

It is not because the diameter of the wheel increases that the speed at which the wheel rotates increases.

Standing here watching Bai Xuemei spinning yarn for a while, Han Chengcheng called it to stop.

Judging from the current situation, there is no need to continue the experiment.

Because the problem now is already very big!

Bai Xuemei stopped her movements obediently, and then returned to the side of the cradle.

At this time, Little Soybean, who was playing around and didn't know when she fell asleep, had already woken up at this time, and had a tendency to want to make trouble.

Bai Xuemei, a mother, obviously has a lot of experience in this regard.

She bent down to pick it up and started feeding the baby.

Little Pea, who was about to make trouble just now, calmed down instantly.

Han Cheng sat here, and after watching his wife feeding the children for a while, he turned his attention to the still unusable spinning machine in front of him again, and fell into deep thinking. My hair is about to fall out...

The weather was scorching hot, and the scorching sun shone on the ground like it was on fire.

On the wheat threshing field, the roaring four-wheel tractor is connected to the hoisting machine through a belt, which turns this thing rapidly and whirrs.

A strong wind came from it, blowing the chaff far away, leaving only clean wheat...

Han Cheng woke up from his sleep, and when he opened his eyes, he saw a piece of moonlight falling through the gourd shed.

Han Cheng lay there without moving, feeling the tranquility of the moonlit night and the beauty of the dream just now.

Reminiscing about the dream just now, his thoughts were suddenly pulled back, and suddenly he was not in the primitive society, but returned to the years and age that he could not go back...

With a warm and somewhat melancholy state of mind, with the appearance of the wheels on the front of the constantly turning four-wheeled vehicle and the turning machine, of course it disappeared.

Han Cheng, who was lying there quietly, sat up suddenly, the moonlight shone on his face, and there seemed to be light shining in his eyes.

He sat here with sparkling eyes.

After a while, he got up with his clothes on, and by the moonlight, he headed all the way to the carpenter's room...

A place in the carpenter's room was lit with lights, slowly flickering under the breeze of the night.

Han Cheng is sitting here, busy with tools in his hands.

Sometimes he will be busy for a long time, and sometimes he will stop his hands and think for a while...

Time passed by little by little, and before you knew it, the sky was already bright.

Bai Xuemei woke up, turned her head to look but did not see Han Cheng's figure.

On the bed where Han Cheng slept, only Little Pea was left.

Brother Cheng unexpectedly woke up without knowing when, and got up.

As if she had a tacit understanding, Bai Xuemei, who stood here in a daze for a while, walked towards the carpenter's room.

In the small courtyard of the carpenter's room, Han Cheng was turning the simple spinning machine with a wooden handle in his hand, making some noises.

At this time, the spinning machine has undergone great changes.

The style of the big wheels has not changed, and has also been rested, making it more tidy.

Next to the big wheel with a diameter of nearly one meter, there is an extra small wheel connected to it...

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

In the early morning not long after dawn, there was still a little fire in the carpenter's room. Han Cheng squatted here, with one hand on his knee, and the other hand holding the wooden handle on the big wheel of the spinning machine, shaking it with his hand. with.

As the big wheel turns, the small wheel next to the big wheel is also driven by the big wheel to turn.

At the center of the small wheel, a wooden stick about the length and thickness of chopsticks is installed.

A curved groove was engraved on the top edge of the stick.

The groove is not wide, but relatively deep, which is used to hold the fibers during spinning.

The small wheel turned very fast. Even when Han Cheng turned the big wheel, he didn't deliberately increase the speed, the small wheel still turned very fast.

So much so that even the groove on the top of the stick on the small wheel is no longer visible!

Han Cheng, who was turning these, looked at the scene in front of him. He hadn't slept in the middle of the night. Not only was he not tired at all, but he was also extraordinarily energetic, with an unconcealable smile on his face.

Even if Bai Xuemei, the little daughter-in-law, has not been allowed to come over to experiment, Han Cheng can be sure that this time the matter is basically done!

I have already figured out the most critical part of the hand-operated spinning machine that I have fumbled and manufactured!

This is really to thank myself for the dream I had last night.
