Wizard: I brought the wrong system.

Chapter 330 Making a Hang Glider

First, the 'fire ant steel' is made into a pipe shape. This saves materials and increases the hardness of the metal, preventing it from deforming during flight.

Just as Yaro was busy, little Heri also came over.

Saltpeter and sulfur are both things that cannot be exposed to fire, so even if she was in a hurry, little Heri would not light lamps for the servants to continue working in the dark.

After glancing at the flames burning in the furnace, Heri walked directly to the foot-operated bellows.

The general structure of the bellows is somewhat similar to that of a bicycle, and it's relatively easy to pedal at first.

"Sir, you've kept saying that the materials need to be crushed. To what extent should they be crushed to be considered acceptable?"

With ample oxygen, the fire in the furnace intensified, and the 'fire ant steel' placed inside melted faster and faster.

Yaro skillfully poured the bright red molten lava into rows of previously made grooves, casually replying:

"Of course, the finer the better, but before that, you need to dissolve and purify the white material several times."

Saltpeter dissolves in water just like table salt, so it can be purified by crystallization, just like table salt.

Saltpeter is called 'ice crystal' among wizards, and even the lowest grade of ice crystal inevitably contains some ice magic. Only through repeated dissolution and crystallization can it be cleaned more effectively.

"Those sulfur compounds cannot be dissolved in water."

“It doesn’t matter if it’s insoluble. Since sulfur is insoluble, it can naturally carry away other soluble impurities,” Yaro said, pulling open the gate next to him. Cool water from the water tower flowed continuously along the pipes, seeping into the grooves on the outside of the mold, and bursts of hot steam rose from it.

“Okay, I understand,” Heri said, sitting on the bellows and watching with curiosity as Yaro began to work on the metal pipes with various spells.

Just like watching someone else weld, even though she's seen it many times, she never gets tired of it.

Ideally, the pipes should be tempered and quenched to adjust the atomic structure inside the metal and make the pipes more stable. However, Yaro didn't have that much time, so he just made do with what he had.

Remove the metal pipe from the mold, measure its position, and then use a heat-melting technique to heat it until it softens, at which point it can be easily bent.

Using this method, the metal pipes are continuously adjusted and connected to eventually weave the general outline of the glider—two triangles joined together to form a large wing, with a small hollow tail with a tail fin at the back.

There is also a vertical pole more than one meter long in the center of the wing, which extends to the bottom of the wing to form a small platform.

This step is not complicated.

However, a specially made deluxe hang glider cannot be made entirely of one material, especially since it was the first time making one, and Yaro was not sure what to do with it, so he also needed some steel wire for fixing.

……

[3:00-5:00: Maintain breathing techniques to nourish and repair the body; free time (to craft various interesting devices)]

……

This was Yaro's past schedule. In the process of crafting various interesting machines, he naturally crafted many matching tools and some small items.

This includes steel wire.

Yaro's method of making steel wire was to heat the steel bar and then pass it through tiny holes repeatedly, compressing the steel bar into a thread through the holes.

It's not too difficult, but it takes quite a bit of time.

Fortunately, the castle had no shortage of manpower, and Yarrow didn't have to do it himself. After he made those tools, servants would regularly refine them to maintain the storeroom's reserves. "Heri, fetch some wire... Oh, right," Yarrow suddenly remembered something, "while you're at it, ask the assistant steward if there's any animal hide glue left in the storeroom, and if so, bring over a lot more."

Animal hide glue is similar in properties to fish glue, but it is harder in texture and can be used as hard plastic.

“I’ll go right away.” Hery nodded; she had done these things many times before.

The armory had long been turned into Yaro's laboratory, and no one was allowed to enter except for a select few.

Therefore, even items specially made for Yarrow could only be stored in the storeroom.

After Heri left, Yaro began to make detailed modifications.

First, holes are drilled at both ends of the pipe, and a pivot rivet is added to each hole.

The unfolded glider is too big to fit in the space ring, so it must be made foldable if it is to be carried around.

In addition to the two ends of the pipe, a joint structure that can slide up and down should also be made in the middle of the horizontal tail fin and wings, and holes should be drilled to serve as connection points for the steel wires.

According to the design drawings, small pulleys for connection are placed at the corners, and cooking oil is added to each location for lubrication.

After Yaro finished all that, Heli came running over, carrying all sorts of things and covered in sweat.

"Sir, the goods have been retrieved."

"it is good."

Yaro took the iron bucket containing the solidified animal hide glue and placed it on the stove to heat it.

Then pick up the steel wire and start connecting the holes that were just left.

Several steel cables are pulled from the tail fin and wings to a small platform below. Two levers are then made to tie the pulled steel cables to the levers, which become the controllers for the glider.

— Controlling a hang glider with your body is too strenuous, so Yaro made an attempt. If that doesn't work, the hang glider is not big, and you can still control its flight trajectory by relying on the strength of your body muscles.

Then, the small power core is inserted into the hole in the middle of the tail fin, just like the 'Eight-Mirror' was remotely controlled in the past. It is connected to the control console by a silver wire and embedded in the center of the control lever to form a silver button.

It's called a button, but it's actually just a solid silver dot, a conduit for magical energy.

The power core was originally installed on the spare Fiery Greatsword, but it was later moved to the spare heavy armor. This is the third time it has been moved to a different location.

It can generate about 100 pounds of thrust, but due to its size, the duration of continuous kinetic energy output is very short. It can only be used as a booster for gliders for short-term acceleration and speed-up.

It wasn't that Yaro was unwilling to create a new and larger power core; the main problem was that too many materials were unavailable in such a small place—even a skilled cook can't make a meal without rice.

So they could only use the spare heavy sword's power core, patching things up by taking things from one place and installing them on another.

……

After continuously adjusting the controllers to ensure that the force on each controller can be accurately transmitted to the wings, the previously prepared canvas can be laid down.

The glider body is made by using heat fusion and steel nails to secure it tightly until there is no room for the canvas to loosen.

Next, we'll build the control panel for the hang glider, which is also the only place on the hang glider where people can stay.
