There are many good things in the arsenal warehouse. Now the troops know the benefits of cars. Every time they attack the Japanese, they will remove the cars and transport them, and they will not even let the tires go. The thing makes a flat-panel truck, load it with small cannons or shells, and don't pull it too fast.

The woodworking lathe is simple. Just build a pulley and drive a spindle. The turning tool is installed on it and then it will be beaten. The only constraint is power equipment. Now boilers are needed everywhere. Good horizontal boilers must first be used for generators, because the pharmaceutical factory urgently needs power supply, and the mechanical team also has to rely on boilers to build guns. Other departments are naturally supplementing with human or animal power.

There are more than a dozen car engines, but unfortunately this thing is made of oil. The Arsenal does not have so much gasoline, and it won’t take long to modify these things.

Zhao Hu focused on the car's shaft sleeves. These are seamless pipes and can be used as grenade guns, but now he can only do everything and build some power equipment first.

Boilers are big and small. The larger ones can generate electricity, such as train heads, and even smaller ones can be mobile, such as charcoal-burning cars. At this time, the domestic oil supply is tight. Most factories in mining areas still use coal-fired boilers as power sources. Unfortunately, these equipment are very large, and it takes a lot of effort to transport one to the mountains.

Zhao Hu first took a few workers to knock out the chimney and combustion chamber with the iron shell on the car. These two parts do not require pressure resistance, so the requirements are not high.

The difficulty is the steam room and the internal water pipes. These are all pressure equipment. For example, the hoop on the top is half water and half steam. The water below must be circulated up and down through the water pipe. The water in the hoop can neither be empty nor full, and must be kept at a certain water level.

Zhao Hu found the seamless shaft sleeves on the car and connected them one by one. This was a disadvantage of the base with a welding machine, otherwise he would not be able to ask the blacksmith to connect the pipes.

The hoop was rolled up with the car base plate and then welded. Since there was no test equipment, he tried to choose thick steel plates. Anyway, no one was here to calculate the cost, as long as the cylinder was not exploded.

The two large flywheels were directly used to use the wheel car of the 92-step cannon to get out of the belt groove. Anyway, the boiler only has ten horsepower, so this thing is enough, which is much better than the blacksmith who poured it out with pig iron himself.

Finally, Zhao Hu ran to the cave again, removed the pressure gauge on several planes, installed it on the hoop cylinder, and also installed several pressure valves on it. These were all secretly unloaded from the overturned train, but unexpectedly they played a role now.

Everything is ready, only the east wind is not available.

It was the turn of installing the liquid level meter, and Zhao Hu realized that this thing was not easy to work, because it was connected to the inside and outside, and it had to withstand temperature and pressure. The key was that it would not work if it was missing. If the boiler was dried, it would be a big accident. But this liquid level meter was not something that ordinary glass could do, so he had to find a logistics department and ask them to find a way to get two from another mining area.

Without saying a word, the comrade from the logistics department sent the soldiers to fight horses and ran out. He waited until the fifth day before he sent a few liquid level gauges, and even a few technical workers brought them.

Zhao Hu couldn't help but wonder that this thing was not something you could buy just by wanting to buy. The soldiers from the logistics department eased his doubts. It turned out that they found an underground party in the mining area and contacted the comrades in the mining area. While the people were inspecting and repairing, they removed all the small parts. Not only did they bring a liquid level gauge, but also several pressure gauges and pressure relief valves.

Zhao Hu was immediately happy when he saw this, and quickly dismantled the simple valve he had made and installed new components. With these precision instruments as a guarantee, the small boiler was finally completely completed.

Looking at his finished product, Zhao Hu couldn't help but shake his head repeatedly. He looked so ugly. The flywheel was on the cannon, the hoop was round or flat, the seal ring was cut by the car inner tube, the water pipe was welded by the shaft sleeve, and the steam pump was leaking when it was pumped. It was a serious product without any of the three products, but it was good to drive the machine tool!

As the pulley drives the rotation of the lathe shaft, the worker presses the wooden stick up. Within a minute, a round wooden handle is freshly released. Then, he puts the wooden handle on the second lathe. The turning tool in the middle of the large shaft turns in, and the wood chips fly, and the inner hole is quickly taken out.

A wooden handle can be produced in just two or three minutes, and the crowds around suddenly burst into warm applause. It is not easy. We can rely on it and use simple equipment to build machine tools. And with this method, no matter which armour station is in the future, we can build boilers and lathes by ourselves. Although it is still very simple, it finally solved whether it exists or not.

After solving the power problem, the bottle diameter will naturally be solved. The squads and guerrillas in various areas also sent a lot of iron ore flowing. The production task this time was so tense that everyone was in a heart. It seems that another war is about to start next year.

Zhao Hu straightened out the grenade production line and returned to the mechanical team. Now the superiors praised the Type 81 horse rifle, and the troops were even more urgently needed it. After all, this was the first rifle designed by our Eighth Route Army, and it would be more respectful to show it out.

Automobile steel, armored vehicle steel plates, all scrap guns and parts are melted into steel. These foreign steels are used as gun barrels, which are many times better than railway track steel, but they are not good for making bolt parts. They are all railway tracks and some worn parts that the troops have cut off from railways everywhere. Now the Second Institute of Ordnance has not yet smelted qualified steel, so they can only be made of materials. As for the self-produced white iron and black-hearted iron, they can only be used to make unimportant weapons such as mortar shells and grenades. It is impossible to achieve it in one step.

During this period, Zhao Hu also learned some outside news that this year, in addition to floods, our army has developed quite well, but it has also been envied by the south. At the end of the year, some people finally began to turn against each other, and some unsightly people began to create frictions. Our army carried out a targeted struggle with reasonableness and conciliation, and finally defeated the other party's conspiracy.

What is even more obvious is that some of the materials and military pay that could still be supplied to our army have gradually shrunk. It is estimated that if this continues, you will have to rely on self-reliance within a year.

Zhao Hu actually knew this news well, but he couldn't say it. He couldn't say it. He would have to fight a blitzkrieg at the beginning of the year. The big rooster of the Gaul was vulnerable. The surname Wang surrendered completely. Zao Yihui was defeated in the Warring States Army?

If you really say it, if you don’t talk about anything else, the bald man had to jump up first and take himself to the mountain city with a telegram. Even if he didn’t slice it, he might not be able to escape the Japanese bombing.

He was in pain and could not say anything. He could only build guns and cannons every day. The military region is now in a hurry to find that the rifle still cannot be opened, so he had to ask the second mechanical team to build some smooth-bore grenades first for emergency response. If the range is not enough, the cannon will be lengthened, and if the steel is not good, the cannon wall will be thickened. In the end, a grenade cannon is heavier than a 60 mortar. In this way, all of them were snatched away by various troops. Everyone was reluctant to use the Japanese grenades after seizing the Japanese grenades, and they were all used as grenades.

The sun and the moon were unknown in the mountains, and heavy snow fell one after another. When the New Year was about to come, Zhao Hu suddenly received good news that Political Commissar Wang was going to get married!

Following Lao Gan, who was promoted to the commander of the group, Zhao Hu was in a complicated mood. Lao Wang announced his marriage quietly. He was completely unprepared and was pulled by Lao Gan with him. It seemed that he had to discuss with Nurse Xiao Yu and prepare a gift for Lao Wang. Otherwise, this guy would have to arrange his own life.
