Chapter 116: Hand drills are not easy to use

The tools of carpentry are actually not complicated, blacksaws, drills, hammers, chisels. What do you think about the ink fountain www.biquge.info, and the falling wire device doesn't need to be done in such a way as ironware inverting.

Yao Ran found out the mold of the two drill bits that he made yesterday, the mold had already been dried and the wooden model in the middle was removed, and the wooden model in the middle could continue to be used as a model after being cleaned up, so as to make a complete set of tools for the standard.

The mold of the hacksaw is very simple, at first it is split with a long thin bamboo, then pressed on the clay, and then with the small triangular arrows of the selected size, all the small arrows are pressed one by one on the clay plate of the whole bamboo, and the drying begins.

After the drying is over, this open inverted mold is completed, the drill bit has been done by Yao Ran last night, and there is a small drill bit that is directly pressed according to the appearance of the agate drill bit that he carries. If the mold of the drill bit goes well, it can come out today, with a total of four pairs of sizes, that is, a total of 8 drill bits.

The process is still yesterday's process, but today there are more tools, in order to prevent the temperature from being too low like yesterday, today's mold pouring process has been improved to be closer to the stove.

The speed of pouring the mold is also because of yesterday's experience, and today's speed is obviously better than yesterday's first time, Yao Ran went into battle shirtless in person when the second pot was poured into the mold and the cast iron saw was poured.

Because the retinal system reminds that if the perfusion of pig iron is uneven, it is easy to break if the cast iron is not so thin. This kind of chainsaw is not the same as a hammer. The hammer is solid, but this chainsaw is only one centimeter thick, of course, compared with the hacksaw in the future, it is already twenty times thicker, but under such primitive technology, Yao Ran is already very satisfied with being able to call the shots of such a chainsaw.

Unless the raw iron is dissolved and then forged or fried in the ancient method, there is no possibility of training mild steel.

It took nearly two hours to go back and forth. Lang Yan followed Xiaoyu back to the camp, Yao Ran came over to check the condition of the grinder, and after confirming that it was correct, he ran to continue pouring the mold. Because the next thing is to be repaid.

The shape of the crescent axe, under Yao Ran's command, was filled with red molten iron, and these axes were poured using an open mold, because the iron axe was slightly thinner than the hammer, but a hole was still needed in the middle to secure the handle.

So it's half perfusion. Yao Ran needed to place a pottery pillar in the middle of the back half of the iron axe. Then continue to pour and cover the molten iron to make it one.

The iron axe designed by Yao Ran also made two shallow air grooves on both sides of the axe surface. In order to cut down the wood, or to cut the animals, not to get stuck in the wood, or flesh.

I poured three pots and four iron axes in one go, all waiting in a cool place for natural cooling. And Lang Yan squatted to the side early and looked at this from time to time, as if he was choosing which one he wanted to take.

And a chick-like chick next to him, Xiaoping, is all kinds of judgments about each axe.

After a while, he said, "Senior brother, this is good!" I just saw that the master stayed in front of this for the longest time! ”

After a while, he said, "Senior brother, you look at this piece is not bad, this shape is regular." Boxy. ”

"Senior brother, you see this is not bad, the compound master said that it is called, the principle of force!"

"Senior brother, have you made your choice? You choose first, and then I'll choose again, who made me a senior brother. ”

Lang Yan was almost annoyed by Xiaoping, but Xiaoping started earlier than himself. He is a senior brother, and he is a junior brother. The clan rules were written early, and the order of the young and the young should not be crossed.

Knowing that at noon, Yao Ran came to the place where various molding props were placed, Yao Ran shook his head, there are no absolutes, even if there is its own retina system, there are still two waste products, but fortunately, they are acceptable, and the reason for the waste is also very simple.

A thin drill bit and a small chisel were completely broken because of the filling and irrigation, in fact, the retinal system can also be monitored in real time during this process, but Yao Ran was checking the situation of the grinder at the time, so these two small things became waste.

Yao Ran thought about it for a while and found a very good educational opportunity. It's to open the scrap first. Moreover, the later mold factory and foundry should be built here, and they must have a special person in charge of this work to supervise it, although no one has been found to be particularly interested in casting.

But at least three of his four apprentices do not reject these things. Or maybe it's to get better tools for yourself, or it's possible that you're interested in it.

Thinking of this, Yao Ran sighed, Yao Ran was sighing, can't the function of the retina system be more powerful and read people's hearts? In this way, you can save yourself a little more trouble. All of this data on technological progress is the only thing the retinal system can provide to itself.

People's hearts are sometimes so dissatisfied, when he first arrived here, Yao Ran complained that he didn't have a golden finger for himself.

And got a golden finger, but not satisfied. You can't tailor a full package for yourself.

People who are selfish and easily satisfied are happy, or people who know how to be satisfied are happy, but it is precisely because of the greed and laziness of people's hearts that the progress of science and technology has been promoted, and the process of civilization has also been accelerated.

Yao Ran took four apprentices and stripped out the cast iron tools one by one, and the molds that could be reused were all taken out by Yao Ran himself. Because it is easy for inexperienced people to break these fragile pottery.

Of course, Yao Ran is also inexperienced, but there is a system, as long as he is not in a hurry and works slowly, Yao Ran's operation experience has risen to the level of a grandmaster.

After separating all the iron tools, the five masters and apprentices squatted on the ground and looked at all kinds of tools, of course, Lang Yan had already held the axe he had chosen in his hand, why was he holding it, it was very simple because it had not been installed, and the appropriate wooden handle.

And Xiaoping followed Yao Ran's side obediently, eager to let himself get into Yao Ran's eyes. In the end, the annoying Yao Ran asked him to choose one by himself. Wait for the wooden handle to be installed together.

Yao Ran took a large drill bit, rode on a log, and used a wooden stick prepared in advance to pass through the hole at the end of the drill bit, and began to rotate the drill bit clockwise. I found that the speed of drilling was still relatively slow.

Yao Ran began to touch his temples again, and asked how to increase the speed of eye punching? The system gave a picture, which made Yao Ran seem familiar, isn't this the original technology brother who made the pressure plate eye-catching! I've done this, I'm six!

Putting down his arm, Yao Ran began to look for materials, and made materials for two different drill bits with the right size ratio according to the requirements. (To be continued.) )
