The old things I repaired have become fine

Chapter 37: New Uses of the Copper Plate Technique

Oh, it seems that I can't be lazy. No, wait, be patient, and say it again. Maybe it will take time for Modou to react?

In order to save himself the trouble, Shen Le patiently explained it again.

Seeing that the inkstone had no reaction, he simply put the inkstone on the table, took another wooden ball, took a pencil, and started drawing stroke by stroke.

Draw a vertex, draw an arc down the sphere, and then draw another arc until the two arcs intersect. Find the north and south poles, and draw several lines at the south pole to divide the sphere roughly into equal parts;
Then extend the longitude downwards, divide the longitude into several equal parts, and draw the latitude lines...

I painted like this for half an hour without looking up, and finally I had roughly, possibly, and approximately drawn the wooden ball.

As for the accuracy, don't worry about it. You can adjust it when drilling later...

Well, if we continue to work like this, we should be able to make a ghost ball. Shen Le gave himself a thumbs up, turned his head, and looked in the direction of the ink fountain——

The smile instantly solidified on his face.

The lead weight was pointed up, holding a small wooden ball, steady and stable. On the wooden ball, the warp and weft were clearly visible, and each line was clean and neat.

In comparison, his pencil drawing, with its repeated strokes and corrections, and its crooked, overlapping and dirty lines, was like a donkey pulling coal standing in front of a Ferghana horse.

Shen Le: T_T
If you are willing to work, just say so!

Just say something!

Oh, you can't talk. Then you can use the lead weight to knock on it, or use your base to knock on the table to remind me?
In any case, the wooden balls have been marked with spots and cannot be wasted.

Shen Le fixed the wooden ball on the woodworking clamp, held the clamp firmly with his left hand, picked up the pen-shaped electric drill with his right hand, and selected the thinnest drill bit to replace it:
"Zi..."

The drill bit rotated rapidly, going deeper into the hole, and sawdust poured out of the hole like snowflakes.

Shen Le held his breath, steadied the electric drill, and let the thin, pen-tip-like drill bit move in a circle along the pre-drawn arc.

After one circle, I saw that the surface of the wooden ball was drawn with a drill bit into a perfect, slightly concave circle...

Based on this circle, drill down and drill inward. Drill out a circular plane, remove a small cylinder, remove the drill bit, and change the tool:

"Well, it turns out that only blade sharpening can take on this important task..."

The blade grinder, as the name implies, is a tool used to sharpen a chisel. A small disc is connected to the top of the drill bit, and both sides of the disc are extremely hard and rough.

In the past, there were no such disc-shaped sharpening blades, so we could only turn the very thin straight blade sideways and cut inwards little by little;

Now that we have a sharpening blade, we can press the sharpening blade to the bottom of the cylinder, close to its edge, and let the blade rotate rapidly, and it will naturally cut inwards:
“Swish, swish, swish… swish, swish, swish…”

The umbrella blade moved slightly, wood chips flew, and the inner and outer layers of the wooden ball separated naturally.
Le controlled the direction of the blade, sticking to the edge of the cylinder, turning it one circle, one circle, and one circle again. The cut was getting deeper and deeper, and after cutting all around, the wooden ball inside could rotate...

"oops!"

Terrible!

The outer shell was cut through!

This ghost ball failed at the first step...

My hands are so clumsy!

Shen Le hung his head in dejection, lamented his own carving skills, and then tried again.

There are 12 round holes marked on a wooden ball, which means he has 12 chances to make mistakes. Whether it is cutting or digging, all 12 holes must be drilled!
Then, Shen Le performed a variety of tricks that were never repeated:
"Ah! It's cut through again!"

"It's been cut through again!" "Ah, the second layer has been cut off!"

"It's cut too deep, the third layer is gone!"

"This hole is crooked!"

"Oops, the ball fell out..."

To drill 1.5 holes and hollow out three layers on a wooden ball with a diameter of 12 cm is a task far beyond Shen Le's craftsmanship.

If the woodworking and carving skills of ordinary art college students are 1, that is, they can cope with homework and occasionally get 80 points from teachers;

Then, after three years of testing, Shen Le's skills in cultural relics restoration can reach level 2.

After all, he would occasionally carve a wooden window frame or a wooden bracket, on which there would be dragons, phoenixes, unicorns, pavilions, figures, flowers, birds, auspicious clouds, and sometimes even works by famous masters.

However, carving a ghost ball, even a three-layer wooden ghost ball, requires a level of craftsmanship of about 10.

Shen Le played 12 holes and failed 12 times; he changed the ball and played another hole and failed 12 times again...

"It seems... using an electric drill doesn't work. I still have to do it manually. The electric drill goes too fast, too fast, and it's hard to control..."

Shen Le sighed, put down the electric drill, replaced it with the smallest wood chisel, paused for a moment, and then replaced the wood chisel with a curved blade with a 7-shaped blade.

Along the gap between the first layer and the second layer, cut in fine detail, bit by bit.

"Back then... the person who made this ghost ball didn't have an electric drill... he had to cut and polish it manually, bit by bit...

As expected, chasing girls is the biggest motivation. He is willing to challenge his craftsmanship and make a ghost ball... What do I want?"

Oh, after I restored it perfectly, the copper sheet gave me super powers, so it’s fine now…

Fortunately, making a ghost ball is indeed a very interesting challenge. Shen Le is immersed in it and never gets tired of it. He broke one wooden ball, broke two wooden balls...

After working hard for several days, until he had used up a bag of wooden balls for practice, he was able to make a three-layered wooden ball that could roll inside.

Although the two inner layers are not smooth and will get stuck when turning, Shen Le can already say with confidence:
I made a ghost ball!

After using up the wooden balls for practice, the next step was to start working on the jujube wood beads. As soon as the carving knife went down, Shen Le screamed:
Help!

The hardness of jujube wood and this wooden practice ball, which may be the hardness of pine or fir, are really completely different things!

For pine or fir, he would hold the wooden ball in one hand and the carving knife in the other, and he could carve it easily.
Jujube wood. With one cut, the blade sank deeply into the wood, and the back of the knife sank deeply into his fingers...

There is a deep red mark on the fingertip!

Shen Le's facial features twitched, and he rubbed his thumb with the joint of his right index finger a few times, rubbing the red mark on his thumb a little. With a bitter face, he carved again, carved again, and carved again...

"No, if this continues, my finger will be ruined before the ghost ball is carved out! At the very least, I'll get tendonitis or something..."

By the way, after repairing it to this extent, can the ink fountain be considered repaired?"

　The cat is a huge handicapped cat.

　　Watching the video of someone making a ghost ball, holding an electric drill and moving it along the drawn circle on the surface of the ball, a very smooth circle is carved out - and that's with a constantly vibrating electric drill;
　　The cat picked up the pen and drew a circle on the surface of the ping-pong ball. It was crooked and the starting and ending strokes didn't overlap at all, not to mention the shape of the circle...

　　Please save your guaranteed monthly tickets for May until Monday, May 5th, so that we can rush to the new book list together. Thank you!
