Yang Cong roughly walked around the ironworking workshop in Xuandachang, and his brows were almost frowned into the shape of Sichuan. 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 powerful tools that surpass the technical level of this era, he would be invincible.

Now it seems that his ideas are really too naive, because there is no industrial foundation in this era, and even if the advanced things are designed, they will be useless. The key problem is that they cannot be created.

This is actually similar to many backward places in later generations. Cars, trains, ships, and planes are very common in later generations. However, in many countries in later generations, they cannot be built. Not to mention cars, even cars cannot be built. Why?

The reason is very simple, because they don’t have an industrial foundation and don’t have any processing equipment!

Not to mention the Ming Dynasty, not only did there be no processing equipment, but there were not even many common materials in later generations. It seems that building an industrial foundation is the top priority. Without an industrial foundation, everything is a castle in the air.

Yang Cong sat alone in the grinding workshop and frowned and pondered, his expression similar to when facing the attack of tens of thousands of Tartar cavalry.

Wang Xuan and others did not dare to disturb him. It was obvious that the governor was in a bad mood. As for why he was in a bad mood, they didn't know why he was in a bad mood. They could only try their best to do the preparations and build the new musket as soon as possible, and try to make the governor feel better.

The next step is to grind after completing the casting. In this era, things with more complex appearances are generally chosen to cast, because if you make a blacksmith, you can't make any complicated parts, especially round things. No matter how powerful the blacksmith is, he can't make a standard round shape and can only rely on grinding.

At this time, the process of grinding the outer circle has actually been quite mature. For example, many gold, silver jewelry, jewelry and jade are quite round and smooth, which proves that the craftsmen now don’t know anything. They do things like grinding the outer circle very well, and they are already a bit close to the grinders of later generations, but it is still purely manual.

The grinding outer circle is a large disc, and then a wooden circular fixture is added to the center to sandwich the things that need to be processed in the middle, then turn the large disc and push various grinding stones against the workpiece.

The things that are ground in this way are quite smooth, but it takes a long time. The iron lumps need to be ground several millimeters or even one centimeter, and the time it takes can be imagined.

Yang Cong frowned again as he watched the craftsman's skillful movements.

These people use ropes to fix the workpieces!

He felt a little fainted. Not only was the slow speed of fixing the workpiece by the rope, the tightening was not enough. It was just grinding. If it was drilling, with such a large torque, can the workpiece be fixed with the rope?

He looked around and soon understood.

At this time, there were 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 threads yet!

After Yang Cong explained for a long time, he gradually understood that the meaning of this thread was roughly similar to the shell on the back of the snail. The circles of the circles were not straight, but oblique.

They can't help with this grinding anyway, and it seems that the grinding takes less than a little time. 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 to demonstrate.

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

These days, there are no machine tools that specialize in processing screws and nuts, and even taps and plate teeth. How can we make standard threads?

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

Fortunately, if the wooden model Yang Cong asked them to process was iron, they would probably not be able to make it for a day when they worked hard.

Under Yang Cong's guidance, several carpenters worked hard for nearly an hour and finally made a set of samples of screws and nuts. Yang Cong took a demonstration and Wang Xuan was stunned again.

How did this governor have a brain? He can think of this thing!

Of course he knew that using this thing to lock the clamp is much easier than a rope. This thing is tightened with just a little twist, and it is not like a rope, it needs to be tightened for a long time.

This screw sample was made, but it is quite difficult to achieve mass production. Even if it is made of wooden, it is difficult to produce mass production.

However, Yang Cong has not had time to consider this issue at this moment, because the outer circle of the rear half of the barrel, the bolt and the bullet shell have been worn out.

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

The craftsmen of these days are really not good at playing the skills. The things they grind out are almost the same as those grinding out from later grinders. Their appearance is as smooth as mirrors!

However, it is useless to polish the outer circle just by polishing it out, and you have to polish the inner circle too.

This inner circle cannot be ground immediately because a large margin is left during casting. You must first drill the holes and expand the holes almost before you can use them to grind them. Otherwise, the inner walls of a few millimeters thick will not be ground out in a day.

How to drill holes now?

Although Yang Cong had already seen the so-called "drilling machine" these days, when he saw the craftsmen actually doing it, his brows could not help but frown.

The "drilling machine" these days is a wooden table. The workpieces that need to be processed are tightened under the table. Then two craftsmen stand on the table, use a T-line drill bit to relay it and drill down hard.

This speed is slow, so it can make people squirt blood. Moreover, the drill bit is not spiral at this moment, but two edges and corners similar to blades are grinded out at the bottom of a square rod.

It is easy to imagine how difficult it is to drill a hole in this kind of drill bit.

Yang Cong stood there and looked for a while, and couldn't help but get hungry. It turned out that half a day had passed without realizing it.

After half a day, I only had to finish half of the process of three simple parts. This progress was so bloody.

Yang Cong finally understood what Wang Xuan said was that he could only make a few new muskets a day. At this speed, it would be great if dozens of skilled craftsmen could make a few new muskets a day together.

Anyway, I can only wait anyway. Except for the drilling craftsmen, no one else can get involved. Yang Cong simply took Wang Xuan and others to the canteen of Xuanhua Factory to try the food here.

During this trial, Yang Cong found that the food in Xuanhua Factory was quite good, with rice, steamed buns, buns and other things pretty good. There is one thing that the dishes here are generally light, and it can be said that the light makes people wonder if there is salt added.

Of course he knew what the reason for the light vegetables was, because the salt was too expensive at this moment, which was equivalent to one or two hundred yuan per pound in later generations. Except for the wealthy families, who dared to put salt into the vegetables?

This problem is easy to solve. He waved his hand and ordered someone to notify the Yang family shopkeeper to send hundreds of kilograms of salt to the Xuanhua factory every month and then it will be cured.
