Yang Cong roughly turned around in the blacksmithing workshop of Xuanda Factory, and his brows were about to wrinkle into a Sichuan shape, he originally thought that as long as he could combine the advanced technology of later generations with the things of this era, and design some sharp weapons that surpassed the technical level of this era, he would be invincible.

Now it seems that his idea is really a bit too naïve, because there is no industrial base at all in this era, even if the most advanced things are designed, it is useless, and the key problem is that they cannot be made.

This is actually similar to many backward places in later generations, what cars, trains, ships, airplanes, are very common things in later generations, but there are many countries in later generations, none of which can be built, let alone cars, even car wheels can't be built, why?

The reason is very simple, because people have no industrial base, and there is no processing equipment!

Not to mention the Ming Dynasty at this time, not only did there be no processing equipment, but even many common materials in later generations were not available, and it seems that building an industrial base is the top priority.

Yang Cong sat alone in the small grinding workshop frowning and pondering, his expression was similar to when facing the attack of tens of thousands of Tartar cavalry.

Wang Xuan and the others didn't dare to disturb him, it was obvious that the governor was in a bad mood, and as for why he was in a bad mood, they didn't know, they could only try to make preparations as well as possible, and quickly build a new type of musket, and strive to make the governor feel better.

The next step after the casting is to grind, and the things with more complex shapes in this era generally choose casting, because if you strike iron, you can't make any complex parts, especially round things, no matter how powerful the blacksmith can't make a standard circle, you can only rely on grinding.

At this time, the process of grinding the outer circle is actually quite mature, like a lot of gold and silver jewelry, jewelry and jade, made quite round and smooth is the proof, the craftsmen at this time are not ignorant of anything, like grinding the outer circle of things they do very well, are already a little close to the grinding machine of later generations, however, it is still purely manual.

This grinding outer circle thing is a large disc, and then a wooden circular clamp is added to the center position, and the things that need to be processed are sandwiched in the middle, and then the large disc is rotated to lean various grinding stones against the workpiece.

The grinding thing is quite smooth, but it takes a long time, and the iron lump has to be ground down a few millimeters or even a centimeter, and the time it takes can be imagined.

Yang Cong watched the skillful movements of the craftsman on the side, and his brows furrowed again.

These people actually use ropes to fix the workpiece!

He simply fainted a little, not to mention the slow speed of this rope to fix the workpiece, the tightness is not enough, this is just grinding, if it is drilling, such a large torque, can the workpiece be fixed with a rope?

He looked around and soon understood.

At this time, there are not even the most basic screws and nuts!

He could only pull Wang Xuan aside and draw a sketch of screws and nuts for others.

Wang Xuan was stunned again, there is no concept of thread at this time!

Yang Cong explained for a long time, and he gradually understood that the meaning of this thread was roughly similar to the shell on the back of the snail, and the circle was not positive, but oblique.

They can't help with this grinding anyway, and it seems that the time required for grinding is not a little bit, Yang Cong simply took Wang Xuan and others to the small workshop for making wooden molds, and prepared to use wood to make screws and nuts out to demonstrate.

He explained to the craftsman inside for a long time, and they finally understood what it was, but soon, Yang Cong encountered the same problem as before, the meaning of the screw and nut is understood, but this thing is difficult to make!

In those days, there were no machine tools for machining screws and nuts, not even taps and dies, so how could you make standard threads?

It's still the old way, you can only rely on your hands, slowly chisel, and slowly pick.

Fortunately, the wood model that Yang Cong asked them to process, if it was iron, it was estimated that people would not be able to make it in a day's work.

Under the guidance of Yang Cong, several carpenters worked for nearly an hour, and finally made a set of samples of screws and nuts.

This governor has a long brain, he can figure this thing out!

Of course, he knew that it was much easier to use this thing to lock the clamp than a rope, and this thing would be tightened as long as it was slightly twisted, and it would be like a rope that would be pressed and tied for a long time.

The screw sample was made, but it was quite difficult to achieve mass production, even if it was made of wood, it was difficult to mass-produce.

However, Yang Cong didn't have time to think about this problem at this time, because the outer circle of the back half of the barrel, bolt and bullet case had been grinded.

Yang Cong took the three parts and examined them carefully, showing a shocked expression for the first time.

The level of craftsmen in these years is really not blown, and the things that are ground out are almost the same as those ground out by the grinders of later generations, and the appearance is as smooth as a mirror!

However, it is useless to polish the outer circle, and the inner circle has to be ground out as well.

This inner circle can not be ground immediately, because there is a large margin when casting, and the hole must be drilled first, and the hole is almost expanded, so that it can be used for grinding, otherwise, the inner wall of several millimeters thick can not be ground out for a day.

How do you drill a hole at this point?

Although Yang Cong had already gone to see the so-called "drilling machine" in recent years, when he saw the actual operation of the craftsman, his brows couldn't help frowning.

In those days, the "drilling machine" was a wooden platform, and the workpiece to be processed was fastened to the bottom of the platform, and then two craftsmen stood on the platform and used a T-shaped drill bit to relay it round and round to drill down.

This slow speed can almost make people squirt blood, and the drill bit at this time is not spiral-shaped, but the lower end of a square rod grinds out two edges and corners similar to blades.

This kind of drill bit, to drill a hole, the difficulty can be imagined.

Yang Cong stood there and watched for a while, his stomach couldn't help but get hungry, it turned out that unconsciously, half a day had passed.

Half a day, processing three simple parts, can only be half completed, this progress, is simply blood-spurting.

Yang Cong finally understood what Wang Xuan's concept was that he could only make a few new muskets a day, and at this rate, even if dozens of skilled craftsmen could make a few new muskets in a day, it would be very good.

At this time, he could only wait anyway, except for the craftsman who drilled the hole, no one else could intervene, Yang Cong simply took Wang Xuan and others to the canteen of the Xuanhua Factory, ready to try the food here.

In this trial, Yang Cong found that the food in the Xuanhua factory was okay, rice, steamed buns, buns and so on were not bad, but there was one point, the dishes here were generally light, and it can be said that the light ones made people wonder if there was salt.

Of course, he knew what the reason for the light dish was, because the salt at this time was too expensive, equivalent to one or two hundred yuan a pound in later generations.

This problem is very easy to solve, he immediately waved his hand and ordered someone to notify the Yang family shopkeeper to send a few hundred catties of salt to the Xuanhua Factory every month and it will be over.

However, the problem of this industrial base is not so easy to solve, because the industrial base is basically equal to zero!
