The assembly of the skateboard is not a difficult thing either.

Workers were curious as they assembled a dozen skateboards individually.

They gathered around, curious about what it was for.

Chu Tianshu took a skateboard, found a piece of flat ground, and put the skateboard under his feet.

To be honest, the material and weight of the wheels do have a great impact on the performance of the skateboard.

Chu Tianshu skated for a while, and then he noticed the shortcomings of this skateboard.

The speed can't go up, the steering is difficult, and it will be very difficult to perform some fancy maneuvers.

But it doesn't matter.

Because if you show it to Gu Feixue or Qi Yingzhi, this skateboard doesn't need too high performance.

As long as you can use it and be able to verify yourself, the goal has been achieved.

As for whether the other party can play the skateboard, and even whether he can play it after getting his hands on it, that is not within Chu Tianshu's consideration.

All he needed was the fact that "I made a skateboard."

The workers surrounded Chu Tianshu, watching him slide around on the skateboard, and there was a lot of discussion.

Chu Tianshu tried for a long time, took the three that he thought were the lightest from more than a dozen skateboards, and threw them to the workers who were a little curious about skateboards: "Novices need someone to support this thing to operate." ”

"If you want to have fun, you can do as much as you want."

After that, he brought three skateboards and went to find Qi Yingzhi.

Qi Yingzhi is not in the factory at this time.

It's not in the house either.

Chu Tianshu searched for two laps, but couldn't find her, so he left the skateboard in her yard.

"Miss Jenny." Chu Tianshu shouted twice.

But in Qi Yingzhi's courtyard, the maid told her that Jenny had gone out after lunch and had not returned.

Chu Tianshu then handed over the skateboard to the maid who passed the word, and told the sixth lady Qi Yingzhi what he wanted, and then left.

The skateboard is made, and the next more important one is roller skates, and the other is arc welding.

The part of the roller skates, because the main work has been entrusted to the tailor shop, is missing, that is, a cowhide upper.

Therefore, there is not much that Chu Tianshu can do.

Her main focus is still on the arc welding process.

Of course, like roller skates, what Chu Tianshu needs to give is not a complete process, and there is no need to consider cost, materials, energy consumption and other issues.

All he needs to give is a technology that actually works.

This is not difficult under the current conditions.

After returning to the factory and asking the old workers about related things, Chu Tianshu took the money out and asked these workers to find qualified raw materials on their behalf.

The workers are quite enthusiastic about this matter.

First, Chu Tianshu was generous and gave them money, without delay, nor did he restrict their use.

After the matter is completed, the balance is not recovered.

The second is to help Chu Tianshu do things, and there are still workers in the factory.

In addition, Chu Tianshu still respects them, so although they deliberately delay their time and do not go back to work so early, they are still more attentive.

Before the shift change at night, Chu Tianshu needed all the raw materials needed for the arc welding process were roughly found.

The one or two pieces that are occasionally missing are harmless, Chu Tianshu feels that they can also be prepared in these two days.

Arc welding, in the era that Chu Tianshu is familiar with, has been popularized as the main welding method.

The main principle is to use arc heat as the heat source between the tungsten electrode and the working element to melt the welding wire and the target metal, so as to realize the process of filling the welding wire.

The main difficulty in achieving this technology at today's technical level is that the commonly used argon gas is not easy to extract.

Of course, if it is only barely realized, and is not used in actual production and life that requires high precision and high technical completion to meet the needs of airplanes and high-speed rail, then argon can actually be avoided.

Instead, it is replaced with carbon dioxide, which is easier to prepare.

Of course, arc welding is not suitable for most work scenarios.

But heavy or?

All the king wants is a patent.

What Gu Feixue wants is not a production revolution brought about by new technologies at all.

She's just asking for money from selling patents.

Chu Tianshu first inspected the metal that the workers had bought.

Workers don't really know what non-ferrous metals are.

So they bought more types of metal.

After Chu Tianshu saw it, he went to see the equipment used to prepare and store carbon dioxide.

After trying to prepare it twice, it was already dark.

Chu Tianshu looked at his watch, it was already eleven o'clock in the evening, sleepiness sprouted, he didn't eat, so he lay down in the factory and slept.

When I wake up, I start to produce carbon dioxide again.

In the steel mill, there is no shortage of raw materials.

It took Chu Tianshu more than four hours to prepare and purify the carbon dioxide, and then began to make protective equipment.

Because a large amount of high-temperature metal slag will be produced in the working process of arc welding, necessary protective measures are indispensable.

The other is the equipment used to make arc welding.

However, it was relatively easy to make, so it didn't take much time.

At more than nine o'clock in the morning, there was a little problem in the operation of the factory - Chu Tianshu's division of labor when he was divided into day shift and night shift was too arbitrary, and he did not take into account the type and length of service of the workers, so that most of the workers in the day shift were experienced technicians.

These people, with some technology, are not willing to do relatively heavy work.

Yesterday, I didn't know how to produce well, and I was busy making skateboards and raw materials for Chu Tianshu, so I fished and paddled a lot.

But today, with a slightly longer working day, the problem is exposed.

Many workers were on the score, and the heavy rolling mill and work in front of the melting pot were simply suspended.

After Chu Tianshu knew about it, he just went over to take a look, didn't say anything, and let the workers stop production.

The management of the factory knocked melon seeds and pointed at Chu Tianshu.

They're looking at jokes.

The old workers in the factory also began to complain about Chu Tianshu at this time.

Without the hard work, their sense of superiority could not be reflected, although it was said that the wages had not decreased, the working hours had decreased, and the factory had begun to manage three meals, and the treatment was better.

But what should be complained and complained about, the workers did not complain even a word.

Gratitude is gratitude, and I feel that Chu Tianshu's hairy boy is blindly commanding, which is another matter.

Chu Tianshu didn't try to solve this matter immediately.

He just washed up, ate some breakfast, brought two skateboards, and hurried to meet Xie Ningzi and Gu Feixue.
