As for the number of turns the cotton thread needs to be wrapped when tying the pen tip, there is actually no clear regulation.

Usually, it is usually wrapped around two circles or calculated, and some masters who specialize in making brushes generally circle around two numbers.

For some larger-sized brushes, at least four or even higher turns are needed.

As for the number of turns of the cotton thread, it can be said to be very simple to judge.

For example, if you want your brush to have a longer service life and prevent it from shedding easily, then you need to prick it a little more.

You know, the hair in the center of the brush, which we called the refill before, is called life hair in the Kingdom of the Sun.

If only a few hairs on the cover of the pen, that is, the softer hairs, were lost, it would not have much impact at all.

However, if the innermost refill loses even one hair, it will be a disaster for the entire brush!

Because, as one hair falls off, this process will continue until all the hair on the refill has fallen off completely.

Moreover, the famous calligrapher Liu Gongquan once said something related to this, such as: If the tip of a pen is tied very tightly, it will only come out with a hair, and it will not be abused.

In other words, as long as another hair on the pen tip at the refill position falls off, the entire pen tip will become loose. As a result, the entire brush will be difficult to control, and it may even be impossible to continue at all.

Used!

Therefore, in some production processes, in order to prevent the above situation from occurring, cotton thread is first used to simply bundle the pen core inside, and then the entire pen tip is finally bundled.

Because the brushes made by Xu Wen and others are not very expensive, and they are just for monkeys to practice.

If the main use of brushes is mainly for practice, then there will be a very large demand for brushes.

This is also the reason why Xu Wen did not fix the pen core again just in case.

"Boss, do you think my pen is up to standard?"

Just when Xu Wen was deep in thought, the monkey group put the pens in their hands in front of Xu Wen.

It has to be said that these little monkeys have made great progress in controlling their own strength.

At the very least, the pen tip they bundled this time already has the basic shape of a brush tip.

As for the shape of the pen tip, it is actually not easy to describe it in words.

If we use some more influential objects as an analogy, it would definitely be bullets.

After all, no matter whether the pen tip or the bullet, the overall shape is a sharp and narrow image at the top and thicker at the bottom.

"The tip of the pen is stuck but it's pretty good. I just don't know what you can do with the subsequent fixation."

Although binding with cotton thread is indeed not a simple task, the subsequent fixing process requires relatively more care from the monkeys.

"The charcoal we need is mainly charcoal that has some warmth on it or looks red!"

"Also, never use charcoal with open flame residue on it!"

After saying this, Xu Wen directly used his iron sword to pick out a piece of charcoal that was still emitting scorching heat from the stove.

Although there is no trace of an open flame burning on this piece of charcoal, it can be seen just from its red appearance that it has a high temperature!

If there is even a little bit of open flame on the charcoal, it is very likely that the entire pen tip will burn instantly.

If this happens, all the previous work will be wasted!

"The next step is to gently place the base of our pen tip on top of the charcoal."

"Although, some places no longer have that red color, and it even looks like there is no warmth at all."

"However, the location we want to place it is this kind of place. Never place it in a red location!"

After saying this, Xu Wen directly dipped the pen tip in his hand lightly on the charcoal.

This feeling is like a dragonfly touching water, and it seems that it will not have any effect at all.

However, at the moment when the tip of the pen came into close contact with the charcoal, the monkeys could clearly see it, as if there was a vague flame flashing past.

Fortunately, this flame only existed for a moment and did not have any irreversible consequences for the entire pen.

Immediately afterwards, as the fire disappeared, a somewhat pungent smell and white smoke gradually rose from the contact location.

"As long as you ask about this smell, or see very obvious phenomena like smoke or fire, it means that our work has been completely completed!"

For the monkeys, they always thought that this kind of work would continue for a while.

After all, as mentioned before, I am afraid that this kind of superficial operation will not have any effect at all.

And this behavior is like when we are frying some French fries, we just pass the potato strips in the oil pan, that is, after putting them in, we take them out within a few seconds.

"Look at the root position of the pen tip. Is there any change?"

While saying this, Xu Wen turned over the pen tips in his hand one by one, so that the root position rushed towards the monkeys.

"Hey, the length of this pen seems to have shortened a lot!"

"That's right, the cotton thread just now was still above the root, but now it's directly at the bottom!"

"Also, the whole root looks black now!"

"No, don't you think these hairs have completely condensed together now?"

The monkeys observed the test object and kept moving their paws at the base.

If it were placed in the past, as the monkeys move, these hairs will definitely return to their original positions one by one, and the overall feeling is also a very soft feeling.
