Chapter VII Bearings

"Alright." Zhang Xuan said: "Needless to say. When you get to the camp, you give me a set yourself, so I can see it. ”

Blacksmith Wang breathed a sigh of relief in his heart, hearing this, Zhang Xuan was still reasonable, but he was afraid that Zhang Xuan would not say anything, so he insisted on punching out 1,500 sets of bearings, which was the business that cost people's lives.

"Yes." Blacksmith Wang said.

When they arrived at the camp, everyone else went to camp. Zhang Xuan pulled Blacksmith Wang and asked Blacksmith Wang to build a set of bearings for Zhang Xuan.

Wang Tie will immediately open the blacksmith furnace and let his disciples and grandchildren take action, but after a while, the furnace fire will rise.

Blazing flames tumbled up, licking a bar of iron.

"Dangdang." The hammer, which weighs more than ten pounds, seems to be as light as nothing, and under the control of the king blacksmith, it beats loudly, as if it were a heavy metal musical instrument.

The iron bar slowly softened under the licking of the flames. Immediately, under the blow of the hammer, it was made into a finger-wide, reddish piece of iron.

Blacksmith Wang hammered a finger-wide piece of iron, and then took a cylindrical iron pillar, rolled the red-hot iron piece on the cylindrical iron pillar, and carefully struck it, using a different force than just now, and the sound made was also a lot crisper. Jingling together, so pleasant.

Immediately into the water, with a "bang", the white smoke rushed out, a gust of wind blew, and a round iron circle came out.

After concocting the same method, an inner ring is created. Then put the inner ring and the outer ring together. The blacksmith then used a piece of wood to cut it into a round ball, put it in it, and tried several different wooden beads, large and small, before determining the specifications.

Immediately, using the wooden ball as the standard, some fine sand was dug up, and then sifted several times, and then the clay mold was created, and more than a dozen were created in a row. Each clay mold is the size of a coin, and then molten iron is poured into it.

After waiting for a long time, it cooled down, in fact, according to Blacksmith Wang's meaning, it is best to dry it in the shade, but where did Zhang Xuan wait for so long. I had to use other methods to cool down.

I took it out immediately, but I didn't know if it was a problem with the mold, or the craftsmanship of the craftsman, or something else, anyway, there were burrs on the beads.

Wang blacksmith and the craftsmen around him polished them one by one. He was busy until the second half of the night, and Zhang Xuan could be regarded as getting a bearing.

This thing may not be called a bearing, but only a roller as blacksmith Wang said.

This bearing, which was larger than Zhang Xuan imagined, was placed in his hand and occupied most of his palm. Heavy press. The color of the bearing is black, and it is by no means the color of the current bearing. And the surface is also rough, and the blacksmith Wang said that it is not well polished.

Of course, it's all a subsection.

The most important thing is how it turns, Zhang Xuan supported the inner ring with two fingers, and the other hand turned hard outside, and the outer ring suddenly turned rapidly.

"Drink, drink, drink." Zhang Xuan obviously heard the sound of turning, coupled with the clear vibration on his fingers, Zhang Xuan was very dissatisfied.

Not to mention the bearing, no, the quality of the rollers. The speed of building alone is too slow.

Zhang Xuan had a small thousand carriages under his command, and Blacksmith Wang fought in the middle of the night before he came up with one, and many things had to be done by Blacksmith Wang. At such a speed, all carriages have to be equipped with bearings, and I don't know if it will be the Year of the Monkey.

It's just that Zhang Xuan saw that the night was dark, everyone was very tired, and he had to get up early tomorrow to hurry, so he didn't blame too much, sighed lightly, and said: "Today, that's it, if there is anything, it's not too late to talk about it tomorrow." ”

The night went by quickly. On the second day, Zhang Xuan asked the blacksmith Wang to install the bearings on the carriage.

However, Zhang Xuan found another problem.

This problem is the problem of the carriage.

Or in later generations, carpentry became a profession that has disappeared, but in this era, carpentry is still a fairly common trade, and there are many people who are proficient in carpenter's craft, and almost every village has skilled carpenters.

But it is precisely because of the general situation that these carts were brought from all over the country by the rebels, and the manufacturers of each cart are different, although they are similar in structure, but from the specifications, none of them are universal specifications.

In other words, if Zhang Xuan wants to install bearings on these big cars, he must make a specification for each big car.

The amount of work is too large, but fortunately, Blacksmith Wang solved this problem for Zhang Xuan, after all, wood is just wood, Blacksmith Wang padd a few pieces of wood, and the bearing was stuck on the axle.

The carriage with the bearings installed, after it has been oiled. As soon as the carriage was pulled, it was much easier.

Zhang Xuan asked Blacksmith Wang, "How long do you think this bearing can last?" ”

Wang Blacksmith said: "The small one doesn't know, the small one has never made this kind of thing before, but from the small experience, this bearing must be made of good iron, otherwise it will not last long, especially this bead, which will break the fastest." ”

Zhang Xuan nodded, he naturally understood this.

He has to be scalable, standardized. It can be mass-produced, and it can be replaced directly if it is broken.

"Perhaps, you can use copper." Cao Zongyu said.

What did copper represent in ancient China?

It's money. Where does Zhang Xuan have such a strong capital

Let's use iron.

Zhang Xuan said to Blacksmith Wang: "You can think now, get a set of molds, don't hit the inner and outer rings, cast directly, and then assemble." ”

"Your Excellency." The king blacksmith said, "The little one can't do it." ”

Zhang Xuan said: "What's the matter? Wasn't it easy to see you do it yesterday? ”

Blacksmith Wang said: "It is still possible to burn a small batch of iron into molten iron, and the small one grits his teeth, but if it is made in large quantities, it is absolutely impossible?" ”

Zhang Xuan said: "Can't? ”

Blacksmith Wang didn't dare to stiffen Zhang Xuan, and said: "There is no guy in the small hand, if you want to burn molten iron, you have to have a big furnace, not a small furnace can bear it." ”

Zhang Xuan said: "In this way, you can only use copper? ”

Blacksmith Wang didn't speak, but he didn't have a speaking expression, he already represented everything, not to mention, the difference in wear resistance, just the difficulty of processing, bronze has already been played by the ancients, what can't be made.

But iron is different.

"Okay." Zhang Xuan said: "I'll go to the general to ask for copper, but you have to be sure of one thing, all the bearings I want are of the same specification, and the parts must be interchangeable with each other."

The blacksmith said, "Your Excellency, you can do it with copper." ”

During the march, Zhang Xuan specially ran to Luo Rucai's place to ask for copper materials.

Luo Rucai looked at the bearing in his hand, flicked it slightly, and the bearing kept rotating in Luo Rucai's hand, and said, "What is the use of this thing?" Do you have to allocate copper? ”

Zhang Xuan said: "With this thing, the speed of all vehicles can be greatly increased, even if the speed of the march is accelerated, the old battalion will not be easily thrown away." ”

"Okay." Luo Rucai said: "Remember what you told me, I allocated this copper material to you, if you can't do what you say, I want you to look good." ”

Zhang Xuan said: "My subordinates know. ”

Luo Rucai said: "Go find Luo Dain." ”

Zhang Xuan said: "Thank you, General. ”

When camping that night, Zhang Xuan got the so-called copper material from Luo Dain's hands.

Most of its realization is now under Zhang Xuan's command, only some important things, more than Luo Dain in his hands, these things are gold and silver, when Zhang Xuan saw the so-called copper material, he knew why Luo Rucai hesitated.

Where is the rebel army any copper material, some only have copper coins.

The copper material that Zhang Xuan wanted was to melt these copper coins.

It's just burning money.

Zhang Xuan said secretly: "If you can't do this thing well, you will definitely be blamed by the above." ”

Therefore, in addition to marching, Zhang Xuan devoted all his energy to this matter, and when he marched every day, he stayed in the craftsman's camp, and after camping, he was also in the craftsman's camp, and he was busy until late at night. Even Luo Yujiao rarely saw his face.

Fortunately, the emperor lives up to his hard work.

Under Zhang Xuan's attention, the first batch of bearings was built, there were 300, of which there were also 50 or 60 scraps, and Wang blacksmith made a mold out of iron. The bronze was poured and the bronze beads were replaced with cylinders, which eased a lot of processing difficulties.
