Daqin: Qin Shihuang Visited The Stalls At the Start

Chapter 404 The seventh group whose precision shocked Su Yu!

Wait! Lego?

A light flashed in Su Yu's mind.

If there is a modern toy that is suitable for all sizes and has the most educational effect, it must be Lego!

If nothing else, just talk about the Lego Bugatti.

The detail of his internal structure is simply outrageous.

If the young people of Daqin could have such toys, it would definitely be of great benefit to Daqin.

Thinking of doing it, Su Yu directly opened the system's product list.

However, with just one glance, he turned it off again.

too expensive!

Even the cheapest Lego bricks cost hundreds of dollars.

It's okay to say, after all, this thing is made of plastic injection molding, because of the "seven-five-zero" material reasons, it will definitely not be low.

But no matter how big it is, building blocks such as some vehicle models and house structures have soared directly to tens of thousands of dollars!

Such a price is ridiculously high for a toy.

But Su Yu is not incomprehensible.

Although these building blocks are toys, they integrate a lot of mechanical structural things in them, so it is strange that they are cheap.

With a sigh, Su Yu was forced to dismiss the tempting idea of ​​popularizing Lego blocks for the Daqin teenagers.

As for doing it by hand?

Just with that number of parts, and the details required.

I'm afraid one set can make a carpenter collapse.

"The wisdom of immortals, Qiyu admires!" Qiyu handed over to Su Yu and made a series.

The rest of Lao Zhao and the others also nodded secretly.

As expected of Su Yu, he was able to see this exquisite structure in such a messy painting.

I really don't know how he did it.

Su Yu handed the drawing back to the rest of the hands, and ordered:

"The idea of ​​yours is very good, and even in concept, it has begun to move closer to our means of transportation. 35

"But there are still several issues that need to be worked out.

"Immortal, say it!" Qiyu's face was full of excitement.

He never imagined that he would be able to receive such praise from the immortals just because of a flash of inspiration.

Su Yu thought for a while and said: "In your car, you should add a structure for the speed change of the vehicle, as well as a device that can be touched at any time to control the stop of the vehicle. 99

“It can’t help but make it more flexible to operate, and it can also greatly improve its safety.99

Qiyu's eyes lit up: "The immortals are right!

He just felt that something was missing in his flash of inspiration.

But after thinking about it, is there any eyebrows.

Never thought that, Su Yu just glanced at it, and immediately revealed the flaws in his idea.

Truly a fairy!

Su Yu clapped his hands: "Okay, this steam engine has also been tested, and the pictures have been read. Let's take a look at this part."

With that said, Su Yu took the lead and came to the stone table.

At this time, a large tray with a multi-layer structure covered with red cloth was placed on the stone table.

This tray contains ten batches of parts selected from the major merchants below.

Come to ten large merchants respectively.

The requirements for casting parts issued by Su Yu are that each company casts some parts of the specified model and produces the smallest gears that can guarantee the accuracy within the scope of its ability.

Of course, the materials used by these people were all provided by the iron smelting Shaofu, and the materials used by standard steam engines.

Hearing Su Yu's greeting, Lao Zhao and others gathered around.

Daniel and the two people next to him, plus Qiyu, took a step forward and came to the table.

Each of the five of them voted three times to select the most suitable three sets of parts in their hearts by way of voting.

In this process, only one person evaluates each time, and the results of the selection are temporarily not made public, only recorded by Li Si on one side.

The first person to review is naturally Su Yu.

Holding the heavy tray, he took Li Si aside and began to observe the parts in the tray.

Opening the red cloth, the first thing Su Yu saw was the slot with the serial number...

In the slot are the parts to be evaluated this time.

Su Yu picked up a transmission rod and looked at it carefully.

The texture is fairly delicate, the thickness is even, the angle is good, not bad.

Although the gear structure is a bit rough due to casting and poor grinding, it is still okay.

The smallest gear is the size of a thumb, but the teeth marks are a little fuzzy, barely...

The transmission lever of the second group...the angle is almost interesting.

The gears are well done, the smallest gear is also the size of a thumb, but the precision is much higher than the first set.

The third group……

Fourth group……

Until the seventh group, Su Yu found only one group of parts, which was quite satisfactory to him.

It seems that Da Qin's current level of precision forging is still somewhat different from what he imagined.

Sighing slightly, Su Yu continued to look down.

"Um?"

As soon as the transmission lever of the seventh group started, Su Yu's eyes lit up.

This is similar to the transmission rod, the texture is very good, and the angle is just right.

It is even better than the first group in which the transmission rod is well done among the previous groups.

Looking further down, Su Yu was surprised to find that the seventh group of gears was also extremely well done, and the smallest gear 5.0 was only the size of a pinky finger.

Almost without hesitation, without even looking down at the other groups, Su Yu directly gave the seventh group a vote.

The difference is so obvious that anyone with a discerning eye can see it.

Among the next three groups, the quality of the parts in the eighth group is also quite good.

So in the end, Su Yu's three votes went to the third group, the seventh group, and the eighth group.

Su Yu came back, and Daniel also began to comment.

Followed by Qiyu, and the other two.

Soon, five people have completed the evaluation.

At this time, Su Yu was very curious.

The parts of the seventh group, which family came from, so that they have such exquisite skills.
