Next, I will watch his performance alone. The electric grinding wheel is brought out, and the sharp sparks rub against each other with lightning. blood tank.
Then light a gasoline blowtorch to heat the part that has just been polished. Use an infrared thermometer to monitor the temperature to reach more than 800 degrees. Put it in water to quench it. After the temperature drops, heat it to about 200 degrees with a blowtorch, and put it aside to cool down naturally. .
Hong Tao's major is metal heat treatment, and he is very familiar with this kind of steel brazing made of 45 medium carbon structural steel. Water quenching is to maintain the hardness, but if the temperature is too fast, the inside of the component will generate a lot of stress due to uneven cooling and heating.
Reheat to about 200 degrees, use low-temperature tempering to eliminate this part of the stress, so that the metal will not be hard and brittle in a certain part, and soft and tough in a certain part, which is easy to crack and deform.
Of course, the tools and materials he used did not meet the technical requirements, so it was just enough, even if he had an electric furnace and quenching oil, he didn't have that much power available. The steel drill treated in this way is a very good gun head, not to mention the skull, it can be used to chisel reinforced concrete.
But how should such a bare steel braze be installed on a wooden pole? It can't really be tied with a rope like Zhang Ke said. Indeed, even if you tie Hong Tao up with wire, it¡¯s too foolish, and it will fall apart after a few strokes. It¡¯s okay for others to use it, but you must be responsible for your own use.
The method he adopted is actually the same as the method of installing the shovel handle on the shovel head. He puts an iron ring on the wooden handle, puts a thin bolt through it if he is particular about it, and nails a nail if he is more unrestrained. Anyway, as long as the wooden handle remains intact, don't plan to take off the gun head.
But how to install the iron sleeve behind the steel drill? Not only Zhang Ke couldn't figure this thing out, even Chu Qiu couldn't figure it out. Could it be that the tail of the forged steel brazing had to be burned red, and the landlord has changed to a blacksmith again!
"Thrillingthrillingsizzling" Hong Tao is not a blacksmith, and he doesn't know how to forge, but he can weld.
Get four pieces of iron and weld a sleeve at the end of the steel braze, then you can install the wooden handle. What? Not round! I'll give you a lung, it doesn't matter if it's square or round, if you can put the wooden handle in and fix it, it will be fine.
But the electricity is cut off, can the welding machine still be used? The answer is still this pile of batteries. If there is a high-power inverter, the welding machine is of course not a problem, and this is not much work, and it will be finished in a few clicks.
However, Hong Tao's high-power inverter happened to be broken, and the power of the 3000-watt inverter can only be stabilized at about 1500 watts. The current is too small to drive the welding machine.
The answer is the battery! There is a trick. When welding small workpieces, there is actually no electric welding machine. You only need welding tongs and ground wires.
Specifically, connect four 80A car batteries in series, connect the welding handle wire to the positive and negative electrodes of the ground wire, and clamp the welding rod to start welding. Although it is not as good as an electric welding machine to start the arc, it is no problem to click a few more times.
Kindly remind everyone, if you want to try it after reading it, it is best not to try it with a new battery, but to find an old one. This method can only be emergency, not the norm. It is equivalent to short-circuiting the positive and negative poles of the battery, and the instantaneous high current will cause great damage to the battery. The time should not be too long, or the battery will explode.
However, if you are driving across the wilderness and suddenly a part is broken and there is no replacement, you can try to connect the batteries of several cars in series, which is also a means of self-rescue.
"Come on, how about a try!" After two hours, the three bare spears were ready. Don't look bad, but it's powerful enough. As long as he aimed and smashed down, Zhang Ke didn't dare to say that Chuqiu's strength and the weight of the steel drill itself were enough to cut through the coconut shell.
"Hiwow" Holding the white wax rod in his hand, Zhang Ke lifted it up with great effort and pointed it at the pickle vat in the corner, but the spear fell into the vat and shattered.
"Damn boy, what can I use to try? I'm going to use it to pickle pickles and salted duck eggs tomorrow. Don't eat it then!" When Hong Tao didn't pay attention, one of the pickle jars in his collection broke. It hurts to step on it.
"Grandpa, this is not a spear, it should be called Ge?" Zhang Ke curled his lips, a little contemptuous of the weapon in his hand. The power is enough, but the appearance is too ugly, the tip of the spear is not forward, but downward.
"Nonsense, it's all about stabbing, how hard you can pierce the skull! Have you studied physics? Zombies don't put their heads on the wall for you to poke, it's moving! Early autumn, is the leather armor sewn up "
Hong Tao really didn't make a spear, and he couldn't pierce the cushioned skull with his arm strength alone. It would be more reliable to smash it down if he wanted to kill him with one blow. As long as the gun body is longer than the zombie's arm, you must aim one at a time. If you want to say that I can't even aim my head, then it's useless to give you a rifle, pure waste.
"Okay, okay, try it on!" While Hong Tao was making a weapon,In time, Chuqiu went to No. 52 courtyard to find two pairs of thick leather boots, and used an awl and tire thread to sew a set of arm and leg guards for Zhang Ke. Put on thick clothes, a hard hat and goggles, and it is estimated that it can withstand two bites from zombies.
If no one comes to rescue after two bites, take the initiative to let the zombie bite again, it's much more comfortable than biting the face, at least you didn't get disfigured, and you have to die with dignity, right?
"Remember, don't be obsessed with fighting. If you miss a hit, back away quickly. When you run, pay attention to your feet, and don't let the stumbling rope trip you. If you really can't run to the car, circle around the car, and take the time to close the door. Open. Those guys won't close the doors, let's smash them while they stop!"
At nine o'clock in the morning, a man, a woman, and a woman, wearing protective gear and leather armor, a helmet, a helmet and a mask, and carrying a two-meter-long spear, or Ge, stepped out of the courtyard gate with great arrogance.
When passing by the No. 52 courtyard, I went in and searched first, and after confirming that no zombies slipped in, I closed the courtyard door with a binding tape to prevent any more zombies from running in. Then I turned into the alley next to it and went to the No. 56 courtyard.
Along the way, Hong Tao still did not forget the trick, but this time he used electric poles and walls as anchors, and arranged three wire tripping cables in a row starting from the entrance of the alley. Finally, I told him about the precautions before cutting off a few straps tied to the gate of No. 56 courtyard.
"Boom Boom Boom Kacha Crash" In fact, just as the three of them turned into the alley, the zombies in Courtyard 56 heard movement or smelled the breath of living people . The sun was gone, and he went crazy immediately, banging the courtyard door.
It's a pity that the courtyard door is pushed inward, they can't pull the door, they can only slam it. When the binding belt was cut, the courtyard door lacked a fixed point, and the range of movement became larger and larger, and soon one door collapsed, bringing down a lot of masonry and soil from the gate tower.
"Let's go! Hey ah" The first zombie died injustice, it was pushed out by the companions behind, and its feet got caught in the threshold. As a result, as soon as he fell on the door, his head was gouged with two large holes and a small hole by three steel brazing rods. So, don't be afraid that the enemy is powerful, but be afraid that your teammates will cheat you!
The first strike of the new weapon is both success and failure. The success is that Zhang Ke can use it to cut through the skull of the zombie. No matter how big or small the hole is, it is a good job if it can destroy the brain. What failed was that all three of them aimed at one target, which was the easiest one to hit. They all had experience in the project of being lazy.
"Don't worry, aim and hit!" Hong Tao didn't have the time to direct who hit which head. He used the longest white wax rod, and it was the most difficult to swing, but the striking distance was the longest. Then don't pick up the cheap ones that fell on the ground, just aim at the guy behind.
Enemies are extremely jealous when they meet each other! Sangou, you fucking fell into my hands. Let you throw garbage bags on my roof! Let you chop stuffed cabbage under the back window of my house early in the morning! Let you puncture my tires! Today we both settle the old and new enmities. Chu Qiu and Zhang Ke swung up and down, but Hong Tao used his strength to change to a sideways swing, from left to right to hit Sangou's face in a circle.
"Wuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuutou To say that the steel drill is hard, and it didn't take much effort to break through Sangou's face door. The skulls were all blown up.
It's a coincidence to say that when Sangou fell on his back, the other half of the courtyard door was also crushed and collapsed. Without the barrier of the courtyard gate, the zombies rushed out in a file, stepped on the corpses of their companions, and rushed towards the living people with big strides, no matter what was thrown at their heads.
