First, make the 'Huoma Steel' into a pipe shape, which can not only save materials, but also increase the hardness of the metal to prevent metal deformation during flight.
While Yaro was busy, little Heli also came over.
Saltpeter and sulfur are things that cannot be ignited. No matter how anxious she was, little Heli could not light a lamp and let the servants continue working when it was dark.
After taking a look at the flames burning in the furnace, Hurley walked directly to the pedal-type blower box.
The large structure of the blower box is somewhat similar to that of a bicycle, so it is quite easy to ride on it at first.
"Sir, you have always said that those materials must be crushed. To what extent do they need to be crushed?"
With sufficient oxygen in the stove, the fire becomes stronger and stronger, and the 'fire steel' placed inside dissolves faster and faster.
Yaro skillfully guided the bright red molten slurry into the rows of previously made grooves, and replied casually:
"Of course, the finer the better, but before that, you have to dissolve and purify the white material several times."
Saltpeter is as soluble in water as table salt, so it can be purified by crystallization like table salt.
After all, saltpeter is called 'cryolite' among wizards. Even the poorest cryolite inevitably contains some ice magic power. Only after many times of dissolution and crystallization can it be better washed away.
"As for the sulfur, they can't be dissolved in water."
"It's the same thing if it can't be dissolved. Sulfur can't dissolve, so it can naturally take away other soluble impurities," Yaro said, opening the gate on the side, and the cold water in the water tower continued to flow along the pipe, and poured into the ditch outside the mold. In the tank, bursts of hot mist evaporated from it.
"Okay, I understand," Hurley sat on the blower box and watched curiously as Yaro began to use various spells to process the metal pipes.
It was like watching other people welding. Even though she had seen it many times, she never got tired of it.
In fact, it is best to temper and quench the pipe to adjust the atomic structure inside the metal to make the shape of the pipe more stable. However, Yaro did not have so much time, so he just started making it.
Take the metal pipe out of the mold, measure its position, and then heat it with hot melt until the pipe becomes soft, then you can bend it easily.
According to this method, the metal pipes are continuously adjusted and connected, and finally the rough outline of the glider is woven into a large wing composed of two triangles, followed by a small hollow tail with a tail fin.
There is also a vertical rod more than one meter long in the center of the wings, which extends to the bottom of the wings to form a small platform.
This step is not complicated.
However, it is naturally impossible to use the same material for a specially made luxury version of a hang glider. Especially since it was the first time it was made, Yaro was unsure, so some fixing wires were needed.
…
[3:00-5:00: Maintain breathing method to nourish and repair the body, free time (refining various interesting equipment)]
…
This was Yaro's schedule. In the process of refining various interesting instruments, he naturally refined many supporting tools and small items.
This includes steel wire.
Yarrow's method of making steel wire is to heat the steel bar and then pass it through small holes again and again, relying on the holes to compress the steel bar into silk threads.
It’s not difficult, but it’s quite time-consuming.
Fortunately, there was no shortage of manpower in the castle, and Yaro didn't have to do it himself. After he made those tools, there were servants who would often refine them and maintain the reserves in the warehouse.
"Heli, please bring some wire... Oh, by the way," Yaro suddenly thought of something, "By the way, ask the deputy housekeeper if there is any animal hide glue in the warehouse. If you have any questions, bring more."
The properties of animal hide glue are somewhat similar to that of fish glue, but it is harder in texture and can be used as a hard plastic.
"I'll go right away." Heli nodded. She had done these things many times in the past.
The weapons depot has long been turned into Yaro's laboratory, and no one is allowed to enter except for a few specific people.
Therefore, even things specially made for Yaro can only be kept in the warehouse.
After Heli left, Yaro began to make detailed modifications.
First, drill holes in two sections of the pipe, and add shaft rivets to each hole.
The unfolded hang glider is too big for the space ring, so if you want to carry it with you, it must be foldable.
In addition to the two sections of the pipe, a joint structure that can slide up and down must also be made in the middle of the transverse tail and wings, and holes must be drilled to serve as connection points for the steel wires.
According to the design drawing, small pulleys are installed at the corners, and cooking oil is added at each position for lubrication.
After Yaro finished doing these things, Heli ran over holding various things and sweating profusely.
"Sir, the things have been brought."
"good."
Yaro said first, taking the iron bucket containing the solidified animal hide glue and putting it on the stove to heat.
Then pick up the steel wire and start connecting the holes you just reserved.
Several steel wires were pulled from the tail and wings to the small platform below, and then two pull rods were made, and the pulled steel wires were tied up to become the controller of the glider.
——It is too strenuous to control the hang glider with the body, so Yaro also gave it a try. If it didn't work, the hang glider was not big and he could still rely on the strength of his body muscles to control the flight path of the hang glider.
Then the small power core is inserted into the hollow in the middle of the tail wing, just like the 'octagonal mirror' was controlled from a distance. It is connected to the console with silver wire and buried in the center of the control lever to form a silver button.
It is said to be a button, but it is actually a solid silver point, a transmission end for magic power.
The power core was originally equipped on the spare heavy fire sword, but was later changed to the spare heavy armor. This is the third position it has been replaced.
It can produce about one hundred pounds of thrust, but due to its size, the continuous output of kinetic energy is very short, so it can only be used as a booster for gliders for short-term acceleration and speed.
It's not that Yaluo is unwilling to make a new and larger power core, the main reason is that there are too many materials that are not available in such a small place, and it is difficult for a clever woman to make a meal without straw.
So I could only take the power core of the spare epee and build the east wall to supplement the west wall. This part was dismantled and installed on something else.
After constantly adjusting the controllers to ensure that the force on each controller can be accurately transmitted to the wings, the canvas prepared earlier can be laid.
Use hot melt technology and steel nails to fix it carefully. Only when there is no loose space in any part of the canvas can the main body of the hang glider be made.
Next is the hang glider control station, which is also the only place on the hang glider where people can be treated.
