The Resurrection of the South Seas of the Ming Dynasty

Chapter 64
With a stable source of materials, there is no need to send manpower to collect, hunt, mine, etc. to obtain.

Zhu Hongyu finally had the confidence to shout the slogan that all people are soldiers. Many women, children, old and weak in the recovery army also walked into the training ground to conduct simple drills with the soldiers.

The Liberation Army now has limited troops, and if there is a shortage of troops during the war, the old, weak, women and children will also have to step up.

……

In the weapons workshop, the cannon-casting team started the first cannon-casting.

Zhu Hongyu stood with Old Liu Tou and watched the whole process of casting the cannon.

The bright red molten iron is introduced into the cast iron film, and the craftsman uses the internal mold water cooling technology to extend a U-shaped conduit into the hollow iron film.

Then cold water is introduced into the conduit, one end enters the water, and the other end exits. The cold water passes through the hot iron film once and becomes hot water.

But in this process, it also took away a lot of heat!

Try to keep the cooling rate of the molten iron inside and outside the iron film consistent.

In this way, the gun body can be avoided as much as possible, and the quality of the gun can also be improved to a certain extent.

Over time, the molten iron gradually cooled and solidified.

The craftsmen worked together to remove the iron film with tools, revealing the still slightly red barrel.

In order to prevent the gun body from cracking, they could only wait quietly for the gun body to cool down by itself, and they must not water it.

Otherwise, wait for the bomb to explode when the gun is fired!
After the cannon body cooled down, the craftsmen stepped forward together and moved the cannon to the hydraulic boring machine together.

A hydraulic boring machine is used to grind the inner wall of the gun bore.

Driven by hydraulic power, the hard carving knife starts to rotate at a constant speed with the rotation of the transmission shaft.

The metal debris was cut off, the inner wall of the gun bore was gradually polished very smooth, and the protruding points were smoothed.

The craftsman stepped forward and used a vernier caliper to measure the diameter of the gun bore.

And it is going to formulate the manufacturing standard of shells according to the diameter of the barrel.

The closer the shell diameter is to the bore diameter, the smaller the gap between the shell and the bore.

The more it can ensure that after the propellant is ignited, the burst energy will not be wasted, and the artillery will be able to shoot with greater power and longer range.

Just like a rifled gun, in order to obtain higher accuracy and longer range, the diameter of the lead bullet used should be one circle larger than the diameter of the muzzle.

Lead is relatively soft. Even if the diameter of the lead bullet is a circle larger than the diameter of the muzzle, it can be loaded with auxiliary tools such as a small hammer.

But artillery is different from firearms. The shells used in artillery are generally solid iron balls, which are much harder than lead bullets.

If the diameter of the shell is larger than the muzzle, it cannot be forced into it.

Therefore, in order to ensure the power and range of the artillery, the manufacture of the shells must also set standards!
Due to technical conditions, errors in shell manufacturing are inevitable, but the errors must not be too large!
Speaking of vernier calipers, it is actually not a rare thing.

Wang Mang, the senior traveler at the end of the Western Han Dynasty, had already made it.

Now Zhu Hongyu ordered someone to make a simple vernier caliper, isn't it reasonable?
There is also the problem of the formula of gunpowder!
Now the world's gunpowder formula, no matter it is the East or the West, Zhu Hongyu's evaluation of it is only three characters, which is unreasonable!

There is a problem with the gunpowder formula, the proportion of saltpeter, sulfur and charcoal is unscientific, and the size of the particles after granulation is also different.

More importantly, in this era, neither the East nor the West has the awareness to distinguish gun propellants from gun propellants.

In their view, there is no difference between gunpowder. Once it is stuffed into the barrel of the gun, the ignition is over, and nothing else matters.

But history has proved that the difference between gun propellant and gun propellant is quite large.

The nitrate content of gun propellant is higher than that of gun propellant. Zhu Hongyu doesn't know the specific reason, but he remembers that it seems to be the case.

After ordering various things to the subordinates, Zhu Hongyu and old Liu Tou left the weapons workshop together.

Zhu Hongyu asked.

"How much is the output of the weapon workshop now?"

"Can you supply the army stably?"

Old Liu replied.

"General, now the weapons workshop's various facilities have basically taken shape, and the weapon manufacturing capacity has been completely released."

"Now, about [-] sets of breastplates, [-] sleeve-type three-edged bayonets, [-] short knives, and [-] shields can be produced every day."

"As well as lead bullets, gunpowder, and thunder!"

The Liberation Army has now abandoned the equipment of spears and started to produce short knives and shields instead.

The reason is very simple, the spear is too long, nearly four meters in length, and can only be used on the plains, and cannot be used in the mountains and forests at all.

Speaking of hand-to-hand combat, short knives and shields are actually more practical.

Zhu Hongyu nodded in satisfaction, then asked again.

"What about muskets? Is there any plan for the production of muskets?"

Lao Liu nodded and said.

"Now in the hands of my recovery army, nearly half of the matchlock guns captured from the red-haired men have been fitted with flintlocks and replaced with flintlocks."

"The production plan of the weapon workshop is to start producing brand new flintlock guns after all the matchlock guns have been modified."

Zhu Hongyu nodded, and then proposed the concept of hand guns.

"Our army is now deep in the mountains and forests. Although the relationship with the surrounding indigenous tribes is not bad at present, there will always be conflicts in the future."

"In order to deal with possible battles with the natives, I designed a repeating pistol."

"The firing mechanism is a flintlock..."

Zhu Hongyu proposed the concept of a revolver.

Loaded in advance, fired by the wheel, can fire six shots in a row, it is definitely a big killer for close combat in dense forests.

As for problems such as air leakage at the barrel connection due to unqualified finishing technology, short range, and poor accuracy.

In Zhu Hongyu's view, this is not a problem.

Just shoot shotguns, anyway, this stuff is for melee combat.

Basically, when you use this thing, it's just sticking to your face.

The range is not important at all, and since the shot is shot, the accuracy naturally does not matter.

As for the poor power, that's not a problem!
A revolver will definitely not be able to hit the Manchu Eight Banners heavy step, even if it is close to the face, it will not be able to break through the armor, but the aborigines don't have armor to wear.

As long as it sticks to the face, let alone one shot, several shots are possible.

As for the plate armor that Zhu Hongyu sold to the natives...

Zhu Hongyu is not stupid, he will definitely strictly control the shipment volume and quality.

Zhu Hongyu asked.

"Can it be done?"

Old Liu nodded, and then spoke.

"You can give it a try, but I don't know if it will work!"

"I've never made a pistol like this before!"

Zhu Hongyu nodded and said.

"Try it boldly, don't be afraid of waste."

"If this thing can be made, our Liberation Army will add a big weapon to deal with the natives!"

Although Zhu Hongyu wanted to unite with the natives to deal with the Spaniards, it didn't mean that he was totally defenseless against the natives.

Non-my family, its heart must be different!
These eight big characters have always been engraved in his heart!

After inspecting the weapons workshop, Zhu Hongyu's expression relaxed a lot.

Push the book, my friend's new book "The Last Great Emperor in the Late Ming Dynasty", if you are short of books, you can go and read it.
