"Okay, oh, by the way, Principal Bai asked me to participate in the science and technology competition of the Children's Palace, saying that I was going to make a work, I almost forgot, I went to find some ......materials first" As soon as Hong Tao heard that his father was about to start a large lecture again, he immediately found an excuse to hurry up, otherwise he would have to listen for another hour and a half.

When Hong Tao was training in the afternoon, he thought about what work he should make to participate in the competition, this thing must not only reflect the highest level of primary school students, but also not too advanced, the materials used must be easy to find, and people must be able to see at a glance that they are better than other works, so as to get an award or something for the school.

Originally, he planned to make a microwave oven, this thing he got when he was in college in his last life, and it was not difficult to make, that is, two boxes with iron sheet metal, one was a box for microwave ejectors, and the other was an oven. When you use it, put the two boxes in line with each other, and it's no problem to boil an egg or heat a meal, and there will be basically no radiation leakage.

But he pondered again, it seems that elementary school students are too early to make this thing, and high-power microwave ejectors are also difficult to find, even if they can be found in the real room of the university through guò's father's teacher friend, I don't know if it can be used, and the price is not low, it is not cost-effective.

So he changed his mind and decided to make a large model airplane, which is not new among elementary school students, and there is a model airplane class in the Children's Palace, making some simple rubber band-powered airplanes or something. Of course, he must be better than them, or how can he win the award, so he plans to make a model aircraft carrier, not only to be realistic in appearance, but also to add a power plant. It's best to add a remote control system, if this can't win the award, then Hong Tao is gone.

Hong Tao is an expert in miscellaneous studies. In my previous life, I also played with models for a period of time, both bought from the Internet and then brought back to assemble by myself, as well as looking for drawings and materials by myself, and made them by hand little by little, and then everyone began to play with methanol motive model airplanes, as well as various competitions, and he thought that thing was too expensive. It's too much energy, so I don't play much.

He also made the aircraft carrier model by hand, which was modeled after the Midway during World War II. It took about one and a half years before and after, and as a result, the hull was ready, the surface spraying was finished, and the carrier-based aircraft and various details were arranged. For example, the villain on the ship, the flag, the anchor chain or something. His interest faded, and in the end, this big guy more than one meter long was invited to the trash can by his daughter-in-law as a rag......

This time this aircraft carrier model, Hong Tao did not plan to make so much effort to get a simulation model that was strictly scaled down, which was not allowed by time. Second, there are no ready-made drawings and materials to refer to, and now there is no computer and network to provide this convenience. There is no material on the details of the aircraft carrier in the library.

According to Hong Tao's plan, the size of this aircraft carrier can still be so big, because the smaller the model aircraft, the more troublesome it is to do, if you want to make a 3o cm long simulation model, then many parts of the ship have to split the toothpick into four petals, too fine, slightly larger, more convenient to process. But the details are all up to their own memory and imagination, what proportion is not proportional, as long as it looks almost the same, it will be over, and it is impossible for those teachers in the Children's Palace to see what the aircraft carrier is like.

If he has time, he also plans to get a few small motors to put in, and then get a battery box to stuff in the belly of the boat, and if he can buy a servo motor, he can also use a simple remote control system to control the rotation of the motor, the direction of the rudder blade, etc., so that it will be perfect.

When Hong Tao asked his aunt to help him find some dried paulownia wood, the aunt thought that he was going to use shoddy paulownia wood to decorate his private restaurant with paulownia wood as hardwood.

"It's not used here, I use it myself, the school asked me to participate in the competition, I plan to make a this, and when the time comes, I have to ask these carpentry masters to help me a little favor, breaking a board, gluing and fixing the work, I can't play alone. Hong Tao is like a big engineer, still holding a roll of drawings in his hand, after opening it densely painted with various components, dimensions and structural drawings, this is his father from the school other teaching and research departments to get him professional drawing paper, as long as his son to the learning side, even if his father to steal, but also to meet his son's wishes, for this competition, Hong Tao has to raise his hands and feet in favor!

"What is this? bathtub?" the eldest aunt took the drawing of the hull part of the ship, turned it over and turned it over, and didn't understand what this thing was more than a meter long, wide at the top and narrow at the bottom.

"You're really funny, where is there anyone who takes a bathtub to participate in the competition, look at this, it's a boat!" Hong Tao's nose was almost crooked, and the drawings that took a week to draw were actually said to be bathtubs, which was too devastating to his self-esteem.

"Hahahaha, what kind of ship are you? Why is there a plane on it? You have to do it, I can't keep up with your brain, you can toss it yourself, if you have something, you go to Master Wang and ask him to help you, I'll buy you wood first, half of it is enough, right?" The eldest aunt looked at the renderings drawn by Hong Tao, his mouth was crooked, in his opinion, there were several planes on a ship, this is not nonsense!

"Don't buy so much! I don't make furniture! Two boards and two five-by-five recipes are enough!" Hong Tao couldn't communicate with his aunt anymore, and the interlacing was like a mountain.

"Master Wang, you can make me a two-meter by one-meter five-meter workbench, just put it in the empty room next to it, and by the way, you can help me take a look at this...... These two boards need to make an arc, if you can't make it, can you splice out an arc?" The eldest aunt didn't plan to continue communicating with Hong Tao, he had already opened the door and left, Hong Tao took his pile of drawings, and went to harass the carpenter master who was renovating the restaurant, and said that the old master grinned, don't look at it as a model, it is more troublesome than making furniture.

From this day on, the empty house above the small building became Hong Tao's studio, and he was the only one who had the key, and in the middle of the room was a makeshift workbench, except for the planed and smooth countertop, the rest of the place was unprocessed wood. On this workbench, there are more than a dozen small wooden sticks inserted to fix the whole of the ship model, which is a small craft taught to Hong Tao by the old carpenter Master Wang, how to shape the wooden board. Of course, only paulownia wood is soft and has long fibers to be suitable for this method, and most ordinary wood can't do this, which is why most of the wood used to make model airplanes is paulownia wood, one is that it is light in weight, and the other is that it is plastic.

Hong Tao has to come here every day after school, little by little to add bricks and tiles to his ship model, large parts can be taken to the next room, processed with carpentry tools, small parts have to be carved little by little with a small carving knife, especially the superstructure of the aircraft carrier, although it does not have to be done 100% proportional, but Hong Tao is still willing to make them closer to reality.

After a lifetime of tempering, Hong Tao has reached the level of sitting on the edge of the reservoir for a week, not a single fish can be caught, and he is not in a hurry, so he is still sure of making this boat.

Now the problem is the servo motor, ordinary toy motor department stores are sold, more than 3 yuan a piece, as long as it is equipped with a simple set of gear sets, you can use it by reducing the rotation. There is a place to get the gear set, and there are a lot of waste clocks and other things in the scrap station, which can always be dismantled and picked up, but this servo motor Hong Tao has turned several large shopping malls and electromechanical stores, and he has not bought it. In the end, Hong Tao had to ask his father for help, asking him to find the old friend who taught physics at the normal university to see if he could get two out of their university's real room.

Time is under Hong Tao's small carving knife, day by day, and summer has entered in a blink of an eye. Hong Tao's aircraft carrier model has basically been completed, the hull of one meter and two lengths, from the bottom of the ship to the top of the mast, is more than 70 centimeters high, not only 7 or 8 MiG-15 fighters are parked on the deck, but even the catapult device and arresting cable, and there are several small wooden people holding small flags standing in different places as deck flight officers.

Now Hong Tao is carrying out the last step, outfitting, that is, painting, this job is also very troublesome, at this time there are not so many colors of paint can be used, and there is no canned spray paint, all the colors have to be adjusted by themselves with several colors of paint. Once adjusted, it has to be brushed at one time, because the human brain is not a computer, and no matter how close the color of this adjustment is to the color of the next adjustment, there is also a color difference. And in order to prevent the soft texture of the paulownia wood from absorbing the paint unevenly, it is necessary to brush a thin layer of varnish first, and then brush the colored paint on it after it is all dry.

No matter how troublesome it is, before the holiday, Hong Tao finally finished his work. This big ship was painted by Hong Tao with red paint on the bow of the ship with the name of the Dongfang Hong, the port number OO1, and a large five-pointed star was drawn in the middle of the flight deck, with two small five-pointed stars in the front and rear. Hong Tao pondered, this should be regarded as red and specialized, from the name to the painting, there is no shadow of the American emperor at all. As a matter of fact, even if US naval experts came, they would not have recognized that this was a US aircraft carrier, and whose aircraft carrier still had torpedo launchers and large-caliber main guns installed on it?
