After the oil came out, Zhao Hu did not dare to store it carelessly. The performance of this thing was extremely unstable and it would explode if it vibrated slightly. Moreover, it had to be stored at low temperature. If the temperature was too high, it would be dangerous.

The best way is to add a stabilizer to make it stable. There is also an alternative method, which is to mix charcoal, etc. to make Judithson. Once mixed successfully, the performance is absolutely safe, and it will not make random noises without detonating a detonator.

Stabilizers are plentiful along the coast, and the best ones are in Jilin, but they are not unavailable inland. There are earth mines in Chifeng, not far away. You can also find them in the surrounding mountains, but the purity is not ideal.

The amount used is not large now. Zhao Hu asked a few workers to go out and find some stabilizers containing impurities. They smashed them with scrubbing to remove impurities such as clay, sand and gravel, and obtained a small batch of high-content stabilizers, which were then mixed with oil.

Come together.

The output of finished products manufactured using this method has increased exponentially. One kilogram of sweet oil can produce more than ten kilograms of patent medicine. Of course, this kind of patent medicine can only be installed in weapons such as grenades and landmines, and is also used to make

Medicine packs or mining will do.

Taking apart a Japanese grenade, Zhao Hu found that it was filled with xanthate, also known as strong medicine. He didn't want to use small pieces of wood to slowly take it out, but directly put it into water to heat it.

As the water temperature increased, a small piece of butter overflowed, and gradually more and more butter came out. Zhao Hu picked up the grenade and took a look and found that all the medicine inside had melted.

Asking Zhang Laoshi to find someone to scoop the butter out to dry in another place or in the sun, Zhao Hu loaded a large amount of homemade medicine into the grenade, then installed the delayed ignition tube and the sounding tube, and then screwed on the firing device on the top.

A homemade grenade is considered finished.

At the back mountain shooting range, there are more than a dozen scarecrows wearing Japanese costumes, all gathered together, squatting or standing. There are also a few imitating Japanese machine gunners, lying behind a small piece of wood to imitate Japanese machine gunners.

Mingzhuang, who had been trained for a while, picked up the test object, pulled out the safety pin, and with a wave of his hand, the Japanese grenade flew out and landed accurately among the scarecrows. Then everyone lay on the ground and waited.

Unfortunately, after a long time, there was no sound. Wang Kaishan finally reacted and slapped Mingran on the head: "You didn't knock just now, did you? I've taught you how many times, why do you always forget?"

Ming Ran touched his head and said a little confused: "Didn't I knock it? It seems that there really isn't one. I'll go pick it up right away."

After saying that, a huge body jumped up from the trench, rushed to the middle of the straw men in a few steps, picked up the grenade and ran back. After jumping into the trench, he hit the grenade on the engineer's shovel hard, and then handed it over.

He said to Wang Kaishan: "Platoon leader, I have knocked this time!"

"Oh no, are you looking for death?" Wang Kaishan's face turned pale with fright, he grabbed the grenade and threw it out, and then slapped him clearly. Zhao Hu looked on beside him and couldn't laugh or cry. He even called this stupid guy over.

I don’t know if it’s a disaster or a blessing, but the only good thing is that I just listen to what I’m told.

There was a "boom", and the grenade more than 40 meters away finally went off. In addition to the pain in his eardrums, he actually felt something flying over his head, making a strange whining sound. Zhao Hu looked up and saw only gunpowder smoke.

During the ascent, a circle of straw men were blown around. Logically speaking, the fragmentation range of this grenade is less than 20 meters. How come something is flying by so far away?

However, at this time, they no longer cared about observing what was behind them. Zhao Hu, Wang Kaishan and others came to the explosion point and found that the grenade had been completely exploded. The broken shrapnel was inserted into the scarecrow's clothes and even the wood was in tatters.

The machine gun was also knocked over by the air wave. Although this does not mean that the grenade can knock off the real machine gun, there is no doubt about its explosive power.

"Okay, this batch of medicine has finally passed the test. Can it be mass-produced later? We engineers are waiting for good medicine." Wang Kaishan said with emotion while holding a piece of shrapnel.

Zhao Hu was also very happy that the first test was successful, but he did not want to use this powerful medicine to make ordinary grenades, which would be too disappointing for his own research.

Returning to the repair shop, Zhao Hu grabbed a handful of iron filings from the lathe. These were the grenade shells that the repair shop had made using the smoldering method a few days ago. After rough lathes, grooves were carved from the outside and left

The crumbs that fell down have not had time to be returned to the furnace.

A few workers had not yet mastered the smothering method. Eighty-eight of the ten grenade casings they produced were broken, and only two could be successfully machined out of the slot. Therefore, the scrap rate was really high. Zhao Hu did not blame anyone.

One, this was originally an emergency method. If you want to improve the yield rate, you need a large number of technicians and learn the American iron casting method to be effective. Now you can only make do with it.

The debris in his hand had different shapes, triangular, semicircular, flat, everything. Zhao Hu found some of the same size, most of which were irregular semicircles. When he came outside, Zhang Laoshi looked at the things in his hand.

When asked what it was used for, Zhao Hu said: "Our grenades have too few fragments. I am not going to use the casing. Do you know where I can find a glue that can stick these iron filings together?"

"Glue? Company commander, you mean to stick all these things on the outside of the grenade? Oh my God, this, this is too crazy, right?"

It is indeed crazy. Later, someone invented a kind of brutal thunder. Only steel balls can be seen from the whole body. The lethality cannot be underestimated. Zhao Hu saw that the shell of the grenade was difficult to make, so he came up with such a trouble-free method.

"If you are looking for glue, tree gum will do. There are mountains everywhere here, and there is a lot of gum exuding from the trees, but there are many types that cannot see water."

"It's okay. We'll just use this kind of glue. At worst, we can wrap it with a layer of waterproof paper on the outside. That kind of oil paper will do."

The oil paper is pasted into a ball shape, filled with Zhudi crude medicine, a wooden tube is placed in the middle, the lower half is the fire pulling device, and the upper half is hollow, with the fire wire placed inside.

The outside of the paper ball is brushed with gum, a layer of iron beads the size of soybeans is glued on, and a layer of kraft paper is pasted on the outside to become a grenade.

There is a cork at the mouth of the wooden tube. When using it, pull out the cork and tip it down. The porcelain ball in front of the lead will slide out. When the time comes, pull it and throw it away. It will make a sound in five seconds.

If the situation is urgent, you can also bite off the cork with your teeth, and throw it out before you have time to pull the wire. The porcelain ball can also pull the fire due to the centrifugal force, but this method should not be used unless it is absolutely necessary.

This little thing is simple to make, easy to operate with one hand, and its lethality is no less than that of a big thunder made by Jin. Therefore, this little yellow egg has been well received by the team as soon as it appeared. Although the waterproof aspect needs to be improved, this thing is

It's so light, with a 50-gram charge and more than 600 iron balls, the total weight is just over a kilogram. One person can carry seven or eight of them, making it a powerful weapon for close combat!

Because the appearance is khaki, and there are stinging things hidden inside, the soldiers call them golden prickly pears. Zhao Hu was not at ease during the experiment, so he threw a few prickly pears on the rocks and found that in addition to

Except for a dozen or so iron balls, most of them were not affected. It seems that this grenade was successful.

Then, he developed a vibrating egg placed in a wooden tube. The principle is the same as that of the two-kick kick. However, it took a long time to design the jumping height of the mine and the explosion duration of the detonator tube. This can be used as a basis for various troops.

The best defensive treasure, as long as the little devil steps on it, they are guaranteed to bloom.

Originally, Zhao Hu wanted to trial-produce roadside eggs, which are the kind of anti-infantry eggs. Unfortunately, the current Zhudi crude drug is a little less powerful, and the explosion distance is only six or seven meters. It seems very uneconomical to use a large amount of drug to make a broad sword, so

I only made some test samples and then put them down.

Violent explosives, grenades, and landmines took initial shape. Zhao Hu rested for two days and prepared to challenge the highest level of explosives, which is thunder explosion. This thing is too violent and harmful to the human body. It has to be handled with caution, so Zhao Hu put
Chapter completed!
