After setting the tone and steps for the production of the scale rod, the "rice" has been opened outside the cave, and since the second batch of pottery bowls will not be produced until tomorrow morning, this meal at noon still needs to be eaten in turns.

The cutting team and the brick-making team gave priority to eating, and the high-intensity physical exertion was huge, and everyone in the tribe had no opinion.

Wang Tian washed the bowl after eating, handed it to everyone, and when the pottery bowl was enough, it must be used exclusively for the bowl.

Otherwise, there are more than 130 people in the tribe. One flu can be wiped out. And if it happens to be attacked by other tribes at this time, the consequence may be annihilation.

There were still two people watching the fire in the pottery kiln, and Wang Tian asked everyone to eat it, and remember to send it over.

The people drinking the soup squatted or stood in various corners of the cave entrance, eating and sucking the soup, and then trying to pick up the fish in the bowl with chopsticks in an awkward posture.

As a Chinese person, how can you not use chopsticks.

Wang Tian instructed everyone to take a two-hour break at noon before proceeding to work. The second brother of King Kong also went to collect the kind of grass used to weave rope nets in the afternoon.

The knotted rope has been remembered for a long time. Now the way the Qinglong tribe records seems to be further, Wang Tian believes that there must be relevant information about the tribe in the pile of stone tablets in Wu.

In the previous census, Wang Tian only roughly counted the number of people. No statistics and analysis of breakdowns are made.

The use of straw rope has long begun in the army. Wang Tian found a straw rope tied to the stones among the weapons they were hunting.

This is supposed to be a throwing weapon, and the primitive ancestors of the land of China have long discovered that tying stones to ropes can make throwing farther away.

From the rope to the net, there may be only a layer of paper separated by the distance, and the piercing of this layer of paper depends largely on an external cause.

When humans barbecued food, they found that the soil burned by the fire became harder, and when it rained, the muddy road surface was sticky, and the indentations left by the legs after walking through them would also give humans inspiration, so humans began to fire pottery.

And a mess of ropes on the ground, after tripping N people, nets also began to appear.

This is like a white bear meeting a black bear, and the birth of a black and white bear has become an inevitable accident.

It is said that now is the era of this goods, and I don't know if there is any trace of them in the bamboo forest in the distance.

After eating, Wang Tian thought in his heart that these messes should be consumed. At the same time, I am also thinking about how to make the scale rod well.

He decided to make the "belly" of the scale rod first, so that the direction of the scale rod was fixed.

First, use a clamp made of two bamboo poles to fix the material of the weighing rod, and then rotate the weighing rod to the position on the side of the fish's belly at the 1/4 mark of the weighing rod.

Use a knife to reach into the carved notch, the knife edge is slightly tilted, and then grasp the handle and the knife head and drag it out, keep a constant speed without pausing, until the tail is weighed, the whole process is completed in one go.

The material of the scale rod is relatively hard, but fortunately, the saber is extremely sharp, so it can be completed even if it is hard.

After several operations, it has been cut to a pre-marked depth. After a little rest, Wang Tian started the other side.

After continuous cutting comparisons, the shape profile of the side of the scale bar has come out. The next step is the processing of the "fish maw".

With the previous experience, there will be more materials to be removed with the addition of "fish maw", and Wang Tian's next cutting degree has increased.

He started cutting from 2/4 of the way, and from here to the tail, the amount of material that needed to be removed was the most, and it was impossible to cut from beginning to end without cutting a part of it beforehand.

After careful and meticulous cutting and constant repairs, after about two hours, the overall outline of the scale rod came out.

Wang Tian stroked the weighing rod over and over again with his hands, judging through the senses of his fingers, and cooperating with visual observation to determine where it still needed to be modified.

I'd rather cut it a few more times. The principle of digging out the groove without using too much force, and constantly repeating the stroke to observe the cutting action. Finally, after the next two hours, the scale rod was finalized.

Wang Tian took out a small piece of animal skin from the cave and walked straight to the kiln by the river.

Go to the stove where the scales are fired, take out the firewood inside, and let it cool naturally. Then pick up the scale pole and go to the river.

Wrap a bag of dry sand in a hide, and wrap the scale rod along with the sand. Then pull back and forth.

Without sandpaper, Wang Tian could only think of this way. Borrowing the friction of river sand, the rough part of the scale rod is smoothed.

After beating the dry sand, wrap it in wet sand and continue to polish. It doesn't stop until you stroke the whole weighing rod as smooth as a freshly skinned stick.

After doing all this, Wang Tian didn't believe that he had done it all by himself.

They were all forced out. After wiping the water stains on the scale rod, I played very carefully and carbonized the scale rod.

It's a pity that there is no tung oil, otherwise brushing with a layer of tung oil can play a more insect-proof, moth-proof and moisture-proof effect.

When Wang Tianhou was born, it was not uncommon to see carpenter Liu Laohan brushing tung oil. As a plant-based natural Qi, the furniture brushed with tung oil basically does not have any pollution and odor, but its protective effect is very good.

Tung oil is a vegetable oil made by pressing the seeds of the tung tree. This is probably the earliest lacquer decoration material of mankind.

The ancestors of China were the first to master the technology of making paints from tung oil during the Warring States Period (475 BC-221 BC). It can use tung oil and lacquer to compound coatings, and also pioneered the technology of adding additives. Until modern times, in a few remote areas and many rural areas in China, you can still see wooden barrels, boats, and furniture painted with raw lacquer with tung oil.

In the West, Europe did not begin to use it in large quantities until the beginning of the Industrial Revolution in the 17th century. Since then, tung oil has been transformed from a handicraft into an industrial product. China did not begin large-scale industrial production until the establishment of New China, and after the world entered the 20th century, with the development of the petroleum industry, coatings were gradually replaced by synthetic resins.

China's leading and backward are also embarrassing.

After the scale rod was made, Wang Tian gave general condolences to the people who made bricks, which made him find a sense of leadership.

The scale was still a little hot, and Wang Tian put it at the mouth of the blower for air cooling.

Since there is no way to make two scales of the exact same weight. Therefore, if you make a rod scale in the future, it can only be a scale.

This is the Lei Gong power distribution mother, the turtle with the king eight, the scale does not leave the stone, the stone does not leave the scale.

If the scale is damaged, only one object of the same weight can be reported first. Then use a scale of about the same weight to hang some weights, and use a balance to ensure that the weight is consistent.
