The old things I repaired have become fine

Chapter 63 Brother, are you even more unreliable? What did you promise me before?
Shen Le burst into tears.

In the field of ancient building restoration, several of his fellow students were forced to study for a second degree in architecture at the neighboring Q University - which can be said to be the best architecture department in the country.

God knows the requirements for a sophomore degree at Q University are not low at all. You have to take classes and take exams with students majoring in architecture.

From thesis to design, there is no aspect where the requirements are lower than those for students of this major!

Poor them, the major of cultural relics restoration, half of the courses are taken with the Academy of Fine Arts, and half of the courses are taken with the Academy of Chemistry. Suddenly they have to study architecture, and everyone is complaining bitterly.

However, they were studying for a second degree in architecture with their junior female students from the medical school of their own school. They felt embarrassed that they were not as good as the medical school, so they had to bite the bullet and work their way through...

Even if they read it, they still have to calculate the mechanical structure on the computer! The instructor actually calculated it by hand! Calculated by hand!!!

They are a bunch of young people, not even as good as their 63-year-old mentor...

Shen Le calmed down and worked hard all day. It must be said that he didn't return to his residence until the sun set and started to deal with the small oil lamp:

"Zizi, zizi, zizi..."

The first step is to disassemble the various parts of the kerosene lamp!

Fortunately, the structure of this kerosene lamp is quite simple. It only uses three rivets to fix it at the lifting rod of the windshield, and the others are fixed by nesting with each other, so it is very easy to disassemble.

Shen Le took a small handheld electric grinder from his senior brother, aimed it at the rivet head, and pressed it down. There was an unpleasant sizzling sound, which made the two junior brothers upstairs run out to see:

"Shen Le, what are you doing? Getting your teeth fixed?!"

"No, I'm repairing a kerosene lamp." Shen Le raised his new collection. The junior shook his head and retreated back to the room. Instead, the instructor walked out and took a look:
"Repair something for fun?"

"Uh-huh!"

"That's great. In our line of work, we must keep our passion!"

Shen Le nodded repeatedly. With his mentor's words, he felt no pressure at all and could work with all his strength. He ground off the rivet head, replaced it with a round punch, aimed it at the other end of the rivet, and hammered it repeatedly:

when!
when!
when!
With every knock, the ash from the earthen stove, the grease accumulated in the kitchen, and the rust fell off.

Shen Le carefully controlled the force, trying to knock the rivet out of the hole without causing too much deformation of the component. Fortunately, the rivet rod had no threads, otherwise, he would never be able to knock it out even if he tried for ten thousand years.

when!
The first rivet is pushed out!

very good!

After removing the first rivet, the protective bracket can be lifted up, and then the glass cover can be removed!

Shen Le was greatly encouraged. Next, he followed the same method to fix the second and third rivets, carefully dismantling all the components and placing them one by one on the table:

The main frame is covered with rust.

The outside of the fuel tank base is covered in rust, but inside... I shone a flashlight on it, and it seems to be okay?
The exterior protection frame, which is the wire ring covering the outside of the windshield cover, is the part that needs the most careful repair. If you use a heavy hand, the rusted wire will break in front of you.
The protective glass cover has cracks and needs to be carefully cleaned. In addition, you need to check how to repair glass cracks;
The hand-held lifting ring and the exterior protection frame are almost rusted. Don't laugh at me, brother. The lifting rod was also knocked crooked during the disassembly process.
The burner part was also rusted inside, and the wick couldn't be raised or lowered. Shen Le gritted his teeth, twisted it for a long time, and finally gave up:
Rust removal!

Let’s remove the rust first!

Dissolve the rust inside first, then turn the knob! I don't believe it, it won't turn when the time comes!
Shen Le rolled up his sleeves and started to wash the workpieces roughly, trying to remove the oil, carbon dust, etc. While washing, he shouted: "Brother! - Where is the rust remover!"

"Sorry, I didn't bring it. Just make do with whatever you have!"

What?
Are all the tools you promised me before?

Brother, can you dare to be even more unreliable?

After severely complaining about his senior brother, Shen Le immediately rolled up his sleeves and started to work on his own.

When working outdoors, you have to adapt to local conditions. People like them who work on building protection may go to any wilderness, and they can't wait until conditions are met before working!
Shen Le found a large basin, poured clean water into it, and poured in baking soda. No matter how poor the mountain village was, there was still baking soda, and the amount was quite large. He poured in a large spoonful, without feeling sorry at all;
Then, he took out the power adapter of the laptop, plugged in a thumb-sized terminal, and screwed the stripped copper wire into the terminal.

At the other end of the wire, wrap the positive pole around a metal rod and throw it into the solution; find a copper wire, wrap all the workpieces around it a few times, connect them together, and throw them into the solution, and connect the copper wire to the negative pole of the wire.

Then, plug it in and watch the bubbles come out!
Gulp, gulp, gulp…

Electrolytic rust removal is very effective. Once the power is turned on, bubbles rise quickly, spreading with light brown rust;
After soaking for 30 minutes, the clear and transparent baking soda water turned dark brown, looking like a basin of muddy water, and the bright metal material was exposed on the surface of the parts;
After soaking for an hour, a thick layer of baking soda floated on top of the water...

"Eh... I've seen it so many times, but it's still so disgusting..."

Shen Le wrinkled his nose and turned off the power. On top of the baking soda water, there was a layer of something that looked like the mold in the grease tank that had been growing for half a year, or like the black skin on a vinegar jar that failed to brew.

Just stir it and it becomes very viscous with a little dark brown foam, which is clearly the rust produced by electrolysis.

Take out the workpieces and take a look:
"Perfect!"

I'll give them some rust prevention tomorrow and then I can start the restoration!

Shen Le rinsed all the parts with clean water, placed them on the table, and let them dry naturally. He yawned and lay down on the bed:

"We can start repairing it tomorrow... This will be repaired very quickly... Huh?"

Why is there a power outage again!

Even though we are in the mountains with low temperatures and no air conditioning or even electric fans blowing all the time, we are not too hot to sleep, but we cannot live without electricity!
Without electricity, how can they charge their laptops? How can they charge their mobile phones?
Nowadays, if your cell phone runs out of battery, can you still live?
Also, if their 3D laser scanner is not fully charged, it will not be able to work tomorrow!

This one is even more heavyweight!
"Hurry up and call! Ask the electrician to come and fix it! - By the way, can you let the electrician stay here? The electricity keeps breaking down!!!"

Half an hour later, the electrician Xiangyang rode his electric bike up the hill again. This time, his face looked very ugly:
"What's wrong with this electricity? I checked it yesterday and it's not broken!"
