The old things I repaired have become fine

Chapter 94: How can I repair this palm-sized piece of furniture? ! (Subscribe)
Without a scanner, Shen Le had to do it manually. Draw two strokes and take a vernier caliper to measure;
Make two more strokes, then take the vernier caliper and measure;
After measuring the length, width and height, you also need to measure the inner and outer diameters of the chair ring. Due to the inevitable errors in hand-made production, the chair ring has slight variations in thickness:

The thickest part is in the middle, and it becomes thinner and thinner on both sides of the armrests. The thickest part of the chair ring is one-fifth larger in diameter than the part where the armrest and the gooseneck are mortised...

These must be recorded one by one for restoration. Make a sketch first, then make the front view, side view, and top view on the sketch;

Then, based on the three views, draw detailed drawings one by one, especially the chair ring, backrest, goose neck, and connecting rods, which are special curved components;

Every component has many, many dimensions to be marked...

Shen Le measured and drew, and was busy for a whole morning before he finished this CAD drawing.

The backrest of this damn armchair is arched backwards at the top and forwards at the bottom. The side curve of the backrest is formed by two tangent arcs, and the radii of the arcs are not the same.
The connecting rod is thin at the top and thick at the bottom, with the diameter of the top and bottom being almost twice as large, and the overall curve has a smooth transition;

And the part protruding from both sides of the handrail, the thing called "eel head", its arc diameter, its length, its landing point...

After drawing all the details and letting the CAD software run a complete drawing by itself, Shen Le fell back in the chair and gasped.

No, there are dozens of miniature Ming and Qing furniture like this on the tray. If I make them one by one by hand, it will take me forever!

[Seniors, please recommend a reliable and easy-to-use 3D scanner, not too expensive...]

Shen Le decisively sent a WeChat message for help. When he came back from dinner, the WeChat group had a ding-dong sound, and several purchase links had popped up.

There are ones priced at 2499 to yuan, some priced at to yuan, and the cheapest one is yuan.

By the way, here are the names and links of some 3D scanning software that can be downloaded on your mobile phone.

Note: The accuracy may not be high enough, the scope of application may not be wide enough, and there may be various problems. Please explore on your own.

…So what was I working so hard for, measuring and drawing?

Shen Le carefully placed an order for a 3D scanner worth yuan, downloaded a scanning software on his mobile phone, set it up and let it work.

Then, he freed his hands and took the miniature armchair, looking at it up and down, and over and over again.

Watch, remember, and mark on the diagram:

"Clip tenon... shoulder tenon... dovetail tenon... wedge tenon... angle tenon..."

Each type of mortise and tenon structure must be understood clearly so that we know how to disassemble them and in what order to disassemble them so as not to damage the mortise and tenon structure inside.

Shen Le looked, remembered, and found pictures of armchairs and videos of disassembling and assembling armchairs on the Internet, comparing them one by one. Alas, relying on human observation and memory comparison is too tiring!

It would be great if there was an ultrasonic scanner. With just one scan, it could measure the mortise and tenon structure inside and its dimensions for you exactly!
Shen Le complained while trying to record and draw. After recording and marking everything, he finally picked up the armchair and began to disassemble it gently:
Remove a component and attach a sticky note;

Remove another piece and stick another sticky note on it;
Take it apart again... Hey!

Can’t take it apart anymore!

Don't worry if you can't take it apart. If you can't take it apart, it's usually because the glue inside the mortise and tenon is stuck. There's nothing that traditional woodworking glue can't get rid of with a pot of boiling water. Pour!

The boiling water poured down. Soon, the woodworking glue in the mortise softened, and Shen Le quickly started to dismantle it.

Some places, such as the chair seat and the chair legs, can be directly pulled out along the mortise and tenon joints.

Some places, such as the chair ring of an armchair, are made of three arc-shaped parts. Two sections of the arc-shaped material are made into hinge shapes, and the tenons at both ends are inserted into the mortise holes of the other party, and a pin is driven in the middle.

At this time, you have to use a small rubber hammer to gently knock the jack pin out of the pin hole...

The palm-sized small armchair and the armchair used in daily life are only different in size. There is no difference in the number of parts and mortise and tenon structure.

Shen Le sweated profusely after disassembling an armchair into more than 30 parts. Without even taking a breath, he quickly wiped it clean and blew it with a high-power hair dryer.

Blow off the moisture and dry the furniture parts to prevent the boiling water from causing more damage to the wooden parts!
This work was a race against time. Shen Le blew all the parts clean in one breath, then spread his hands and feet, leaned back in his chair, and let out a long sigh:

Finally done!
My God, these parts are as big as seven or eight centimeters long, and as small as the size of a fingernail. It is not convenient to use force when taking them apart, and I am even afraid of leaving marks from my fingernails.

How did the people who made them make the mortise and tenon structure on the tiny woodworking parts...

Oh, these mortise and tenon holes still need to be repaired and the stains cleaned...

Shen Le sighed deeply. It was fun to choose a topic. He finished the crematorium. Before that, he repaired the ink fountain, puppets, and oil lamps, which took no more than a month. Now, this dollhouse?
Can it be done in half a year?

If we start now, we may be able to get it done; if we don't start now, we will never get it done. Shen Le concentrated and calmed down, and began the next steps:
First, wipe it with a soft cloth to remove as much dust and dirt as possible;
The second time, use a brush to clean the mortise and tenon holes to remove the dirt and residual glue in the mortise and tenon holes;

The third time, use the smallest needle knife and ear pick to clean the mortise hole thoroughly bit by bit...

This job is not hard, but it is extremely detailed and tedious.

Even if Shen Le was wiping a full-size armchair, it would only take him ten minutes to finish. However, it took him half an hour to wipe the parts of the miniature armchair.

He had to wipe every turn, every groove, and every tiny part. After wiping it once, even if he set the air conditioner to 22 degrees and even if he had experienced the test of the ghost ball, he was still sweating.

Well, it was mainly because Xiaoling was out at work and not by his side. Otherwise, even if Xiaoling couldn't help him clean every detail, at least she could pass him tools and talk, right?
Shen Le sighed and continued to work hard. Next, he cleaned the mortise and tenon holes to remove the residual glue.

The tiny needle knife and the tiny stick turned over and over again on the 0.5 cm thick parts and in the mortise holes of one or two millimeters...

"Boss, what were you thinking when you made these things?"

While Shen Le was working, he complained in his heart:

"Some things can be fixed with glue, why do we have to make a mortise and tenon structure... It's just a dollhouse, just a dollhouse!"

It took Shen Le half an hour to clean it up, but it took him a full hour to clean all the mortise and tenon structures. After finishing everything, Shen Le was already impatient, so he grabbed a glass of iced cola and gulped it down:
"so annoying!"

To restore cultural relics, one needs to remain calm, have a mind as clear as a mirror, and hands as firm as a rock.

Sitting at the workbench for an entire morning, using tweezers to piece together a shattered painting bit by bit, or repeatedly comparing and searching among the vast number of porcelain pieces to find the one that belongs to the same vessel.

Choose one thing and stick with it for the rest of your life. Once you start working, everything in your heart will be quiet, and you will only see joy and peace, without any anxiety or irritability.

Shen Le once thought he could do it. But now it seems that he still can't do it. At least, in front of this miniature furniture, he failed...

Throwing down the empty Coke can in his hand, Shen Le heard it spinning around on the concrete floor, making a squeaking sound. He felt annoyed, took a few quick steps, and stepped on it:
"Squeak-"

It's even noisier!
So annoying!

Shen Le walked from the workbench to the studio door, and then from the studio door back to the workbench, making two circles in a row.

There are dozens of these miniature furniture with mortise and tenon structures in the dollhouse, in addition to various miniature electrical appliances, miniature pots and pans, miniature chandeliers, and clothes for the dolls.

With so many things to do, how long will it take him to finish repairing them?
How long can he endure this kind of manual work that is done bit by bit, slowly, with the progress bar so slow that it is almost non-existent?
Shen Le took a few deep breaths and forced himself to calm down. Being angry was useless, and throwing things was even more useless. Did he regret it and not repair the doll house?

no way!

Then I have to force myself to calm down... Come, sit on the single bed next to you and meditate for a while!
Shen Le slowly calmed his mind, regulated his breathing, and entered the state of practicing Qigong. His mind gradually calmed down, and the heat flow surged up little by little, circulating around the body and reaching all parts of his body...

He floated in a dark state of concentration, using his mind to feel and capture the points of light in the darkness, pressing them into himself, feeling the heat flow growing stronger bit by bit.

Finally, when I opened my eyes again, I felt a sense of peace and tranquility. The irritability and impatience I had just felt had completely disappeared.

The level of spiritual cultivation is not enough!
We need to work harder!
By the way, can I maintain a state of mind similar to that of practicing Qigong and force myself to calm down while working? If I can, I won't be troubled by the irritable and trivial mood when I work in the future...

Shen Le felt ashamed, and returned to the workshop, picking up the cleaned parts. He snapped them back together, and it was a little loose and shaky, but not much.

It seems that the main reason for loosening and deformation is that the wood undergoes natural deformation over a long period of time.

Of course, there was a very small amount of rot in the mortise, but it was a very easy fix to put a little pad in the mortise.
Shen Le was ready to start. He prepared the woodworking powder, woodworking glue, and woodworking clamps. He picked up the woodworking glue and was about to apply it to the mortise and tenon when his hand suddenly paused:
He had a feeling that using wood glue was not the best method. The repair would not be good enough, not perfect, and would cause some damage...

Very important stuff...

What was it? Shen Le didn't know. He subconsciously opened his spiritual eyes to see, and saw a faint aura flowing through the parts of the miniature armchair he had disassembled;
Even if it was disassembled, put in order, and cleaned from top to bottom, that layer of aura still penetrated every part, forming a naturally flowing aura...

So, will using wood glue block this aura?
In other words, will the use of modern chemical products hinder the flow of this aura and prevent the further growth of the consciousness of this dollhouse?

How to verify it?
Shen Le spent four years in college and three years as a graduate student. He did countless restoration work, read countless monographs and papers, and naturally, wrote at least a dozen papers.

However, none of these monographs and papers, not a single sentence, told him:

When repairing cultural relics, how should we choose materials to better bring them back to life, or to make old objects that have already come back to life have stronger spirituality?

"So I still have to do the research myself... Well, design the experiment, control the variables..."

Fortunately, this was not difficult. Shen Le quickly found a wooden stick, and after rummaging in the box for a while, he found a small piece of leftover fish bladder glue.

I sawed off four pieces of wood from each stick, and then sawed off two pieces of wood from each stick. I put two sticks and one piece of wood in a pile. I put a stick of chemical wood glue on one pile and a piece of fish bladder glue on the other pile, and then I sighed:

"So traditional glue will be eliminated..."

Even when they were repairing ancient buildings in the past, if the objects were not very important and did not require reversible repairs, they would be lazy and use modern woodworking glue and never use traditional glue!

He picked up four short sticks, walked to the third courtyard on the west side, and stretched his hands upward. Void grabbed a handful of the aura from the small building, attached it to the short sticks, and wiped, wiped, wiped -

It was not until the four short sticks were infected with the same aura and no difference could be observed with the spiritual eyes that he returned to the studio.

Okay, now let’s see which one is better at guiding these auras, modern wood glue or traditional fish bladder glue!
