In the power workshop, Zhu Houwei frowned and stared at the burned black coil and said, "The insulation is still not good."

Several copper smelting masters have a bitter face, they are coppersmiths, to melt the copper and draw it into copper wire and then weave it into a coil, the difficulty is really not that big, even if it is not difficult to make a hand-cranked generator with the coil as the core, you only need to make it according to the drawing.

But the insulation of the coil is very difficult, and now it is wrapped layer by layer with oiled paper, and the final effect is not too understood, and the successful hand-cranked generator can run for two or three hours at most, and it will inevitably burn out.

Two years has taken too many methods, but none of them can ensure the long-term use of the coil.

"You can go to find rosin, resin and other things to blend together to make insulating paint, and then mix foam materials to neutralize and try, how to do it, this king has only seen a few words in the book, so I don't know very well, this has to rely on you to try slowly."

Zhu Houwei also has a headache, the process of making insulating paint is not too complicated, but he doesn't remember it too clearly, so there are not many suggestions he can give.

For electricity, which can be called the product of an epoch-making scientific and technological revolution, the emergence of electricity also directly promoted the second industrial revolution in the original history.

With electricity, it does not mean that Zhu Houwei will benefit thousands of households, and he will study what tungsten filament makes of light bulbs, but in order to promote mechanical productivity.

For example, large machinery in the workshop area, such as hydraulic forging machines, grinding machines, drilling machines, etc., these lathes can indeed greatly save manpower, but the efficiency is also not high, once there is electricity, then the efficiency of the lathe driven by electricity can be greatly improved, so that many things can be mass-produced.

But now it is clear that if you can't solve the problem of insulation, you want to use power efficiency on a large scale, which is tantamount to a dream.

I can't eat hot tofu in a hurry, Zhu Houwei has time, and if he can't improve it in a year or two, then three or five years, three or five years will not work, then ten years and eight years!

Zhu Houwei really didn't believe it, he had enough time, enough financial support, and could provide ideas to open windows for craftsmen, but in the end he didn't get a return.

What does he want in return?

Armor! Swords! Firearm!

Armor doesn't need to be said, no matter how complicated the armor is, as long as there is iron and people, it can be made!

It's like a fish scale armor and chain mail exclusive to military generals, and in Yongwangwei, any soldier can be equipped, which is not a rare thing.

The second is the sword, the peak of the development of cold weapons in the feudal era should be the Tang Dynasty, the Tang Dynasty knife is even more brilliant, known as the existence of blowing hair and breaking hair, but it is a pity that after the war at the end of the Tang Dynasty, the craft of the Tang knife has long been lost.

However, this loss refers to the loss of China, when the Wa sent Tang envoys to the Tang Dynasty, it can be said that everything is learned, whether it is clothing, culture or medical treatment, and craftsmanship have almost been copied again, the Tang Dao of China has been lost, and the Wa State has not only been lost, but also carried forward and improved the Tang Dao, forming today's Wa Dao!

Whether it is a Tang knife or a Japanese knife, Zhu Houwei is not interested, no matter how strong the cold weapon is, it is only a cold weapon after all, before the hot weapon is not on the stage of war, the cold weapon still has room to exert residual heat, but once the hot force becomes the mainstream on the battlefield, no matter how sharp the knife and gun is, it will only be marginalized.

He wants muskets and artillery!

Nowadays, after Zhu Houwei personally instructed the craftsmen, there are no technical barriers to break through in the artillery technology in the workshop, and the processes such as primer, mini bullet, burst, rifling and so on are also becoming more and more mature, but the biggest limitation is that it still cannot be mass-produced.

Without a streamlined workshop, it is impossible for a bullet to be error-free by just relying on manpower to polish it a little bit, and even if the error can be minimized, it takes a craftsman several days to make a bullet!

This speed is so slow that it makes Zhu Houwei's scalp tingle!

Today, there are nearly 100 craftsmen and apprentices engaged in polishing and manufacturing bullets in this workshop, but even so, only 3500 bullets can be made in a month.

Three or five hundred a month, five or six thousand a year, and even if you are skilled in ten years, it will not exceed 100,000 in the end!

What is 100,000 rounds of ammunition for? Even if it's just Yongwangwei's soldiers and horses, each soldier is assigned thirty or forty rounds, not to mention changing the form of war on the battlefield, even training is not enough!

Therefore, Zhu Houwei is now eager to use electricity to manufacture relatively fine lathes, and then turn small workshops into large workshops and carry out assembly line operations, so as to form large-scale mass production.

"How many of the latest muskets and how many cannons are there in the workshop today."

"If you go back to the master, there are 137 muskets, five mortars, and one howitzer in the workshop."

It's been two years, and the muskets are just over a hundred, and the artillery is negligible......

After solving the technical problem of priming fire in the capital, Zhu Houwei handed over the design principles and simple drawings of the mortar and howitzer to the workshop, and the craftsmen in the workshop lived up to his expectations, and finally succeeded in manufacturing these two weapons of mass destruction.

Zhu Houwei even imagined more than once that when these two powerful artillery pieces appeared on the grassland, in the face of the roaring grassland cavalry, ten thousand cannons fired at once.

It must be a human purgatory with flesh and blood, stumps and severed arms everywhere!

With such a killing weapon, Zhu Houwei did not dare to say that he would completely solve the major trouble on the northern grassland, and it was almost a sure thing that he could fight for the Ming Dynasty for hundreds of years.

But this output, Zhu Houwei can only hehe, this is like the nuclear deterrence of later generations, if only one or two nuclear bombs can have much deterrence, if you want to form a nuclear deterrent, you must have a large number of reserves, you must have the ability to make nuclear bombs anytime and anywhere.

Now for Zhu Houwei, the gun manufacturing workshop has this ability, but it does not have a large number of reserves, so it is impossible to form a deterrent.

"Master, I'm going to go to the gun workshop." Ren Xing saw that Zhu Houwei's brows were tightly locked, and he looked very unhappy, and immediately asked cautiously.

"I'm not going." Zhu Houwei sighed and said: "This king knows the reserves, and he also knows the crux of the gun workshop now, if it is not large-scale, no matter how strong the artillery and muskets are, it will be just a flower in the mirror, and everything will have to wait for the bottleneck to be overcome here."

Hearing this, he was immediately ashamed, in this workshop, in addition to restricting the freedom of King Yong to go out, all other treatment can be said to have been done to the extreme, but he still disappointed King Yong after all.

"Then the master wants to go back to the palace?"

Zhu Houwei thought for a while and said, "Restaurant!"
