Otherwise, how could His Majesty have designed such an exquisite hydraulic lathe?

In fact, there were already artificial lathes during the Ming Dynasty.

Its main function is to drill holes and drill gun barrels.

For example, the barrels of guns used by all the armies of the imperial court are drilled out in this way.

In general, the barrel is not made from ordinary cast iron sheets.

Instead, it is specially beaten, processed into iron rods, and after repeated beating, the internal pores are removed, and then sent to the gun-making workshop for subsequent processing.

After the gun factory brings these iron rod raw materials, they remove the most problematic ones, and then use deep hole drilling to drill holes in the remaining iron rods.

These holes must be drilled through with iron rods before they are reamed.

The so-called reaming is to squeeze the barrel that has begun to take shape from the inside and polish its inner wall smooth.

However, Zhu Youxiao, who has seen high-end goods, obviously dislikes the barrel made of the rickshaw.

Because the barrel made by the rickshaw is too inefficient.

It is obviously very backward to rely only on manpower to constantly rotate the lathe to achieve the purpose of drilling.

But in this era, there is no steam engine, let alone an electric engine, and the most likely thing to achieve is a hydro lathe.

For example, the hydraulic lathe designed by Zhu Youxiao was designed using the knowledge of his later generations, as well as the carpenter's talent and skills in the mind of the Emperor of the Apocalypse.

This hydraulic lathe can be said to be very exquisite, enough to increase the drilling efficiency of the original rickshaw lathe to more than three times.

Sun Yuanhua is now looking at Zhu Youxiao, and his eyes are full of adoration.

Who said His Majesty was a faint king?

But in the eyes of these people.

Your Majesty, this is really a great talent!

"Your Majesty, after taking a look at this hydraulic lathe, you can deduce that with such a thing, the time we want to cast the barrel is at least two-thirds."

"If Your Majesty can give me enough manpower, I think within a month, the minister will be able to focus on making three hundred suitable barrels."

Zhu Youxiao shook his head.

Leaving aside the barrel thing, that's not the main thing.

The main thing. It's better to hurry up and build more and sharper artillery.

The current artillery is obviously useless, and if he wants to fight Jiannu, the power is too small, and the weight is too high, so he can't achieve the effect he wants.

"You look behind you first, I hope you can build me at least fifty of these cannons before the spring of next year."

Zhu Youxiao's drawings for Sun Yuanhua are a lot.

The detailed drawings of the hydraulic lathe just now only account for less than one-fifth of them.

That Sun Yuanhua turned to the position of the artillery, and when he saw the style of the artillery, there was a surprised expression on his face.

Isn't this a breech-loading gun?

Dogs don't use this thing!

It's no wonder that Sun Yuanhua looks down on the rear loading gun so much.

It's really this thing, too far worse than their red-clad cannons.

Although the words are also well-informed.

Sun Yuanhua has seen a rear-loading gun.

Not only had he seen it, but he even shot the reloading cannon himself.

Speaking of the history of rear-loading guns, it was a long, long time ago.

On March 21 of the second year of Jiajing, a fierce battle broke out between the Ming Dynasty naval army and the Franc machine man warship in Xicaowan, Jiangmen, Guangdong.

The Ming army finally captured 42 people, including Bedulu and Shu Shili, beheaded 35 people, and captured two warships, which is known as the "Battle of Xicaowan" in history.

The scale of this naval battle was not large, but the Ming army gained a lot.

At that time, the Ming army had already obtained a Franc machine gun on the captured Franc machine man battleship.

This Franc cannon is very special because it is a rear-loading smoothbore cannon consisting of three parts: the barrel, the belly and the sub-cannon.

When the Francophil fired the cannon, he loaded the subcannon with gunpowder and projectiles in advance, and then put the subcannon into the belly.

Then the Franc robot man then aimed at the light door on the barrel of the cannon, and then lit the fire door of the sub-cannon to fire the iron cannonball.

The Ming army found that this and the special Franc machine gun had many advantages that the Ming artillery did not have.

First, the Franc cannon had a fast rate of fire.

Because the Franc machine fire adopted the technique of separating the projectile and the cannon, the rate of fire was extremely fast.

The Ming army later cast heavy Franc machine gun, that is, the "invincible general cannon", one main cannon with three sub-cannons.

According to the calculations of the Ming army, when their ordinary artillery fired one shot, this heavy Franc machine gun could fire three shots.

Thirdly, the Franc cannon dissipates heat quickly, because it belongs to the rear gun, and after the fight, you only need to pull out the sub-cannon, put it next to it to dissipate the heat, and then replace it with a newly installed sub-cannon.

Fourth, the safety of the Franc cannon is high, and the gunpowder installed in the sub-cannon is very constant, so to a certain extent, the risk of exploding the bore is avoided.

Fifth, the barrel life of the Franc cannon is longer, because the sub-cannon bears a certain bore pressure, so the life of the barrel is extended.

Therefore, after the Ming Dynasty obtained the Franc cannon, it began to imitate and improve, and the total number of casts reached more than 30,000.

At the end of Jiajing, the Franc cannon had become one of the main equipment of the Ming army.

If this Franc cannon is so powerful, why is it almost not cast now?

Of course, there is a better choice!

Although the Franc cannon has various advantages, it cannot be ignored that it also has relatively fatal shortcomings.

That is, the airtightness between the cannon and the belly of the cannon is not good, so the gunpowder gas leaks out of the belly, resulting in a short range of the gun.

Sometimes, shortness is a fatal shortcoming.

When the Jiannu cavalry charged at high speed, the Franc cannon was too short to suppress the opponent because the firing distance was too short.

That is, its rate of fire is fast, but the distance is too short.

The Ming army here hasn't fired a few cannons yet, and the Jiannu cavalry over there has already been close to the face.

Later, God blessed the Ming Dynasty, and the East India Company's "Unicorn" battleship encountered a typhoon in the waters near Yangjiang, Guangdong, and the battleship was damaged and sank.

Five years later, the fishermen caught shells from the battleship.

Deng Shiliang, the governor of Guangzhou, learned the news, organized boats, hired fishermen who were proficient in water, and salvaged 36 18-pounder naval guns.

Deng Shiliang transported 24 of them to the capital.

At that time, when the Dutch entered the Ming Dynasty, many soldiers were dressed in red, and there was a small bundle of red tassels on their hats, like a pinch of red hair.

Therefore, the Ming army called this new artillery also known as the "Hongyi Cannon".

The biggest difference between this Hongyi cannon and the Franc cannon is that the Hongyi cannon is a front-loading smoothbore copper cannon.

In addition, it can shoot twice as far as the Franc cannon, and can get two to three miles away.

At the same time, the Hongyi cannon has the advantages of great power, long barrel, high precision, and thick pipe wall

In the sixth year of Tomorrow's Apocalypse, when Nurhachi led 60,000 Jiannu troops to besiege Ningyuan, he was killed by this kind of artillery.

Therefore, the Ming army has such a good thing as the Hongyi cannon, and it is no wonder that Sun Yuanhua can't look down on the rear-loading cannon.

Although it is an excellent rear-loading gun, it looks different from the Franc cannon.

But a rear-loading gun is a rear-loading gun, and it is simply impossible to be reliable.

"Your Majesty, you can't do this!"
