The old things I repaired have become fine

Chapter 98: Little Modou, you have become a bad person! You actually mocked me! (Subscribe)
Therefore, Shen Le really didn't know how to apply paint. Combining the knowledge he had heard in class before and the results of searching for information, he figured out one thing:
First soften the patent leather, and then stick it on with a specific glue.

As for what to use to soften patent leather?
Different monographs and papers give different answers. For example, using steam to soften patent leather -

I only mentioned this sentence. As for how much steam? How much distance? How long is the softening time? What should I pay attention to during the operation?
Sorry, I didn’t say anything.

Another paper talks about mixing propylene glycol, ethanol and water in a ratio of 5:3:2 by volume and soaking them until softened.

However, the formula of this softening agent is suitable for paint leather that is stored for a long time in the high temperature and high humidity environment in the south, and has thicker and more brittle paint skin.

The cabinet in front of Shen Le has been stored in the Jiangsu and Zhejiang regions for a long time, where the temperature is relatively low and the paint is not thick. God knows whether this softening agent can be used and whether it is effective.

Shen Le was particularly helpless and tried to find a solution. On the one hand, he hugged his senior brothers and sisters, asking them for advice and information;
Secondly, try to practice on your own...

Fortunately, a batch of old furniture and old wood were dragged back from the mountain village.

Shen Le rummaged around and found a wooden table with a broken leg. The tabletop was covered in mottled red paint, and was quite similar to the cabinet he was going to repair.

Shen Le perked up and mixed propylene glycol, ethanol and water in proportion, trying to soak the paint that had been knocked off the wooden table. Xiao Ling helped him while mumbling and asking:
What is propylene glycol?

"Oh, bring me that bottle of glycerine over there. - the pharmaceutical grade one! Not the one I use to wipe my hands!"

[Okay. This is propylene glycol, and this is ethanol.] Xiao Ling picked up a bottle and brought it over, then picked up another bottle:
[By the way, where is the water? I saw it said to use deionized water... How do I get deionized water? ]

Oh, Pinocchio has made great progress and can actually read papers.

Although the level of his paper reading is still debatable, in terms of following the clues, he is already as good as a complete layman with a pure liberal arts background.

Oh no, Pinocchio can read papers now. Doesn’t that mean she has become more proficient at watching videos and browsing Taobao?

What if she uses my account to buy a lot of clothes for her? The clothes for babies on Taobao can cost tens of thousands of yuan each!
We need to think of a way, for example, to require fingerprints for payment...

Shen Le collected his thoughts and began to instruct the puppet to work. You can learn a lot from reading papers, but you can't understand some of the little tricks that only experts know.

Deionized water actually needs to be prepared using ion exchange resins, reverse osmosis membranes, etc. However, Shen Le's use of it does not require this.

"Go, bring me that bottle of Wahaha purified water... the unopened one!"

Yes, the answer is Wahaha purified water.

The level of purified water is basically purified water -> distilled water -> double distilled water -> deionized water (triple distilled deionized water) -> ultrapure water. Wahaha drinking purified water is ultrapure water...

It is prepared in the laboratory itself, and those with poor skills cannot even compare to the pure Wahaha!

Xiao Ling grunted and brought back pure water. Shen Le recorded, mixed, stirred, and experimented:

"Hmm... it doesn't seem to be going well? Try a different recipe?"

He tried one formula after another for two days in a row, until the lacquer, fish bladder glue, various pigments, and various tools and materials arrived, and then he pulled his head out of the seventeenth version of the formula:
"Huh... According to the paper, this thing needs to be soaked for nine days to achieve the best softening effect. The waiting time is terribly long. Forget it, let's fix the cabinet structure first..."

He skillfully pasted a strip of masking tape on both sides of the crack between the cabinet top and the cabinet body, leaving only the crack exposed. Then, he dipped a rattan stick in the heated fish bladder glue and applied it into the crack:

"A little less... a little less... too little, add a little more... No, a little less..."

Too much is not good, it will easily overflow, penetrate into other areas, and affect the drying of the glue;
Too little is not enough, otherwise it will not play a good reinforcement role.

The speed is too fast, which will cause uneven application.

If the speed is too slow, the fish maw gelatin will freeze when it cools down, and you have to cook it again...

Even though Shen Le had cooked many times before, he was still sweating profusely this time, and he dared not breathe heavily. While he was working, a thin voice suddenly sounded beside him:

[You are too slow! Apply faster! ]

Shen Le turned his head and saw that the inkstone had already appeared, holding the lead weight high and "staring" at the cracks he had painted. Shen Le was speechless for a moment:
Well, the level of the little inkstone was inherited from its owner, one... maybe two level eight workers.

Although the two of them made molds on a daily basis, as carpenters, they must be proficient in all kinds of skills. There is no reason why they would not be good at painting and applying glue.

Besides, if people in that era had some skills, who wouldn’t make a set of furniture for themselves?
The old couple's entire set of furniture seemed to be made by themselves...

"Then you come?"

He simply handed the cane over. The lead weight rose, touched the cane from his hand, pulled it back, and touched the cane again -

The cane was motionless and unresponsive. Obviously, this thing had not been soaked in the aura of the ink fountain for a long time, so it could not be controlled.

The ink thread twitched once in anger, then twitched again, and flew back to the next room with a whoosh. Soon, a cane wrapped around it flew back quickly and dove into the fish bladder glue. Swish, swish, swish. With a few light and smooth movements, the glue application work was completed.

The ink line flew away and returned to the cane. Then, it flew back again, circling and twisting in front of Shen Le, forming a ball. It even made a contemptuous gesture...

Shen Le was stunned.

Zheng Mo, you have become a bad person!

You actually know how to make this gesture!
What did you do during the time I left you alone in the house?

Who taught you this?

Or did you secretly watch TV that you shouldn't have? !

However, Shen Le did not have time to pursue these matters. While the fish bladder glue was still wet, he quickly placed a piece of cloth on both sides of the cabinet panel to protect the cabinet body.

Place a piece of wooden board of medium thickness on top of the cloth to bear the pressure.

The metal clamp part of the woodworking clamp is on the outside of the wooden board. Clamp both ends and start tightening the screws:
“Squeak… squeak…”

Shen Le listened attentively to the slight creaking sound and slowly turned the screws one by one. He couldn't tighten them all at once, but had to tighten them slowly so as not to use too much force and damage the cabinet.

During the twisting process, listen carefully to the sound of the wood moving to help determine whether the cabinet top plate has moved back to the correct position...

[Almost there! Keep going, keep going! ]

Modou shouted. As he shouted, he raised the lead weight, turned it on the side of the cabinet, folded it, and let it hang down again.

Shen Le saw a very short horizontal ink line on the side of the cabinet, which gradually shortened with each turn of the screw...

Very good, little ink bucket, you can help with the work now!
With your observation from multiple angles and help in measurement, I won't over-tighten the screws and damage the cabinet!

But that's not a reason for you to mock me or make weird gestures at me for no reason, right?
In any case, with the help of Xiao Modou, Shen Le applied glue to the cracks and displaced parts of the cabinet, clamped them with woodworking clamps, and declared that the repair of the main structure was preliminarily completed.

Next, it’s a long wait:
The time required for fish bladder glue to dry is much longer than that of chemical wood glue. Chemical wood glue usually dries completely within 24 hours, but what about fish bladder glue?
Same temperature, same humidity, 72 hours of walking!

"So how can we blame fish bladder glue for being replaced by chemical glue? It's not as convenient to use, it works slower, and it's more expensive. When you calculate everything, the cost and work efficiency are four or five times worse!"

In addition to these cultural relics restorers and some enthusiasts, such as those who like to make bows at home using ancient methods...

The users of fish bladder glue have basically become extinct.

Shen Le sighed and clapped his hands. He was about to continue repairing when his phone suddenly vibrated. Mo Dou rolled up the phone and handed it to him. The puppet jumped up to help him scratch the screen.

Hey, when did you guys even remember my unlock password!

If you continue like this, are you going to forge my fingerprint and place the order yourself?

Shen Le didn't have time to question them, as the WeChat call was connected. Gu Yulin on the screen spoke anxiously, looking behind him as he asked:

"Mr. Shen, where are you now?"

"At home?" Shen Le turned his head reflexively, trying to calm down the inkstone and the puppet and pretend to be normal objects.

I turned my head halfway and then I remembered that the person opposite me was a member of the Special Affairs Department - that's fine, just do whatever you want:
"what happened?"

"It's like this. The old lady, the former owner of the doll cabinet, went missing today. Do you have any clues?"

"clue?"

Shen Le was at a loss. That person is your senior, you know her situation better, what clues can I have?
But he was more concerned about the fact that he was lost. After all, he was an elderly person, and a sick elderly person, old and frail.

In the news, there are often reports of elderly people with Alzheimer's disease walking for more than ten hours and dozens of kilometers. If they are found too late, who knows if anything will happen to them.

He shook his head, frowned and asked back:

"Lost? When did he get lost? Have you not found him yet? Have you searched everywhere you can?"

"She went missing early this morning. Her grandson lived with her, and when he came back at noon, he found that the old lady was missing." Gu Yulin looked sad:

"We checked the surveillance footage and found that she went to the old house and left the house soon after. There was no surveillance footage for the next section of the road, and then we lost track of her... Do you have any clues?"
