Dai Quan's appearance is very ordinary, and he can't find a shadow at all when he throws it on the street.

However, as the first eighth-level worker in the workshop under the Chu Palace, he is almost an all-powerful existence.

Especially for the production of various equipment and instruments, the entire Datang may not be able to find someone more proficient than him.

This time, Li Kuan was going to get something new, and naturally it was handed over to Dai Quan to be responsible for the overall planning.

"Dai Jiaoyu, this thing, the other parts are easy to say, and it is not difficult for our mechanical workshop to produce it. But this chain is really a bit troublesome. ”

Dai Quan is now a part-time teacher at the Gewu Academy of Guanshishan Academy, and he likes to be called Dai Jiao by others.

Zhong Rixin, as a craftsman in a mechanical workshop, is naturally very clear about this.

"This chain is the most critical part of the bicycle that the prince said, as long as it moves, the chain will continue to wear out. How to ensure the service life of the chain is a big problem. And it can't break every once in a while, otherwise this thing won't be meaningful. ”

Dai Quan was also a little worried.

It's not difficult to make a prototype at all.

But when it comes to making bikes on a large scale, and ensuring longevity and quality, it's very problematic.

"Master, I heard that half of the bearings and gears of the Mercedes-Benz Carriage Workshop are now purchased from the Jintai Iron Workshop, and the steel used to make these gears and bearings is processed by the Aniu Special Steel Workshop next to the Jintai Iron Workshop. Why don't we come back with a batch of special steel from the Aniu Special Steel Workshop and see how the quality of the chain is? ”

Shi Bingming, who was standing next to Dai Quan, put forward his own suggestions.

As Dai Quan's apprentice, Shi Bingming is not afraid of whether this suggestion is taboo.

No matter what time it is, this kind of thing involving the procurement of goods is more sensitive and easy to get into trouble.

Why do people in later generations have all kinds of associations when they hear about purchasing?

It's really in this industry, there are too many doorways.

And in many cases, there is a lot of room for inexplicable operations in the procurement of goods.

Just like some units, they always don't like to purchase some well-known welfare products, but specifically select some relatively unpopular ones.

Why?

Because there's a lot of space inside.

For example, when buying a carton of milk, the market price of several common big brands is very transparent.

You can't buy a box of Mengniu and end up spending hundreds of dollars, right?

However, if you're buying niche dairy products, there's a lot less price transparency.

"Ah Niu Special Steel? How come I haven't heard of it? ”

Dai Quan thought about it and was not impressed.

"Master, the Ah Niu Special Steel Workshop has just become independent from the Jintai Iron Workshop this year. I heard that they have some cooperation with the Gewu College of Guanshishan Academy, which specializes in purchasing steel from the ironmaking workshop in our palace, and then taking it back to re-smelt it into steel with some special properties.

This theory is said to have been put forward by His Royal Highness the King of Chu during a lecture at Guanshishan Academy. Judging from the current situation that the apprentices know, the Aniu Special Steel Workshop should have made some achievements in this regard, otherwise Mrs. Jin would not have let it become independent. ”51

Although Shi Bingming did not study at Guanshishan Academy, as Dai Quan's apprentice, as long as he was willing, he could still have access to a lot of information.

Just like the Aniu special steel workshop, in fact, the scale is not very large, and the special steel produced is mainly supplied to the Jintai Iron Workshop, and ordinary people do not pay too much attention to it.

Just like the people of later generations, whether it is Mercedes-Benz BMW or Toyota Volkswagen, no one will care which steel mill produces the steel plate of the body, and what kind of special steel is used for the wheel bearings on the wheels.

"Since the Aniu Special Steel Workshop is a special steel made according to the ideas of His Royal Highness the King of Chu, let's go and purchase a batch and come back to try it. We have to make a batch of samples as soon as possible, so as to determine the production process of the bicycle in the shortest possible time. In the workshop city, the plaque of the permanent bicycle workshop has been hung in front of a workshop, and if we drag our feet by then, then my old face will be lost. ”

Because the workshops of this era did not have to lay the foundation in advance for the installation of special equipment, as in later generations, the workshop buildings were built in advance, and then production could start after quickly installing some recommended equipment.

The Chu Wangfu also tried the sweetness from this model, so there were several empty workshops on standby in the workshop city for a long time, and new workshops were being built.

"Master, I'll personally go to the Aniu Special Steel Workshop now and come back with a few batches of special steel."

Shi Bingming looked resolute, and turned around and left after speaking.

……

"Lord Wang, is this the bicycle you are talking about?"

In the courtyard of the Chu Wangfu, a bicycle that looked strange in the eyes of Wu Meiniang and others was quietly parked in the courtyard.

This is the prototype that the mechanical workshop has just sent over, and Li Kuan specially asked it to come over, so that everyone can see it first.

"Yes, Mei Niang, don't underestimate this bike. As long as you are proficient, you can ride thirty or forty miles in an hour, and you can walk two or three hundred miles in a day. ”

"Two or three hundred miles?"

Wang Xuanwu's eyes lit up on the side, and he couldn't help but ask rhetorically.

"That's right, if you meet someone with good physical fitness, and you've been on a flat cement road, you can walk more than 300 miles a day, and you don't have to ride a horse slowly. And unlike horses, the bike is tiring and needs to be fed and cared for at home. You just need to add some whale oil to its chain and bearings regularly, and you can basically use it however you want. ”

Although the bike in front of me is ordinary, even a little ugly.

There are no rubber tires, no exquisite painting, it is completely the product of a combination of iron and wood lumps.

But Li Kuan couldn't help but want to give it a try.

"Wow, you can really walk, you won't fall!"

Li Kuan skillfully pushed away the tripod, sat on the cushion with his buttocks, and stepped on the pedal with his right foot, and the bicycle walked forward.

Cycling is a technique that you will never forget, once you learn it.

Li Kuan just walked around the yard a few times, and immediately found his senses.

Although this bicycle is a bit more bulky, the basic structure is no different from that of later generations, and Li Kuan feels that he is still quite satisfied.

After finding the feeling, Li Kuan rode faster and faster, and the reaction of everyone in the yard became more and more enthusiastic.

"Lord Wang, let your subordinates also give it a try."

As soon as Li Kuan stopped, Wang Xuanwu couldn't wait to try it.
