By changing the height of the furnace to 20 meters, and by the fact that the dwarves did the most difficult powdering of magic stones, the upper part of the furnace was also ready in a day.
If it was true, it would have been done in half a day, but it took a day because the Haberdashers made fine adjustments.
However, the furnace that was built just by sticking to the boulder was very beautiful. It is perfectly symmetrical, and the smooth curve from the bottom of the furnace to the top and the circular shape of the cross section in the furnace are perfect.
"...... Alright, it's inside!"
Hmm, that's a lot!
After checking all the corners of the furnace, Habel and the others put their arms together and said that. Apparently, it was satisfactory.
As soon as Haberdasher and the others were convinced, they discussed the windbox.
"There are eight wind holes in the lower part, four in the middle, and four in the upper part. I'll open and close it according to the furnace conditions."
It's better to leave all the lower parts open.
"If you send too much wind, it may cool down, but there's probably no problem with the lower part that gets hot." I'll always send the wind so as not to block the wind hole. "
"How many wind boxes do you make?" After all, should we make four of them? "
That's right. If you make four of them, you can move two of them, or you can move four of them.
It seems that the Dwarf furnace uses manpower to burn the inside of the furnace. I would have called it a wipe in Japan.
A dwarf air feed box is a device that feeds air by increasing or decreasing the volume of air in an airtight container fitted with an intake and exhaust valve.
The windbox was well thought out, and in the middle of the box, the room could be divided into two parts and the wind could be blown in alternately. Heavy as it is, he will be able to send the wind as long as his health lasts.
But it was still a tough task. Looking at the blueprint I just wrote and listening to Haber's explanation, I wondered if I could do more.
Speaking of automatic operation, it is electricity, wind power, and hydro power. There is always water flowing from the river in this village of Ceato. Then, is it hydropower that is used?
"...... maybe I'll try to remodel it a little bit"
When I muttered that, Hubbells leaned their necks toward the eyebrows.
Ahn?
"What are you talking about?"
The havels made such a reaction with their jaw-dropping faces. No, half of them were stunned and looked at with ridiculous eyes.
If you don't take this a bit seriously, you may be involved in the ticket as a lord.
I decided to use the water drawn from the river to make a trick. [M] I tried to use the water wheel to alternate the two wipes. Rather than increasing or decreasing the volume of air by stepping on it, it is a form of blowing air by moving the wall from left to right and increasing or decreasing the volume of air.
By making the structure like a pedal of a rowing boat, air can be sent to the furnace by the power of water.
When they actually made it, Haberdasher and the others kept their eyes wide open and silent. In the meantime, we'll leave the immobile handles alone and make a pipe to the wind tunnel. A sealed box was made to store the wind supplied from the water wheel, and a valve that could be opened and closed manually was installed there. Beyond that, there are a number of pipes that extend around the furnace.
Where do you build a wind tunnel?
When I turned around and asked Haber and the others, I saw a dazed face with my arms together.
"... it's really against the rules."
I can't stand it.
"I want that magic too."
The dwarves said something about bumps, but Habel hits himself in the face before calling out.
"Hey! I'm building a furnace now!" Let's think about the location of the wind hole! "
When Havel said that, the dwarves struck themselves in the face and swarmed toward the furnace for some reason.
"The lower and upper parts are fine."
The wind hole in the middle is slippery
"Yeah, that's a lot of wind."
"Hey, put a mark on the furnace wall."
While arguing noisily, the dwarves draw a black circle on the furnace wall.
Okay, this is it, isn't it?
I wonder if it's finished at all. Haber looked up at the furnace and said so. And the dwarves nodded.
Yeah, it's all right.
This is a lot of stuff.
It's very, very noisy. Does that mean you can do it well?
With that in mind, I made something like an iron straw. [M]
So, should we install this kind of wind tunnel?
Asked questions to confirm, the dwarves changed the color of their eyes.
"No, no!"
"Don't cut the tip of the wind hole at a right angle!" It'll clog up in no time! "
"In the middle, you should narrow it down and spread it out deliberately." It prevents backflow. "
"In six months anyway, the tip has melted and been replaced." Iron and stone will melt away. "
After listening to such conversations, I wondered if I could somehow protect the area around the wind tunnel, and I processed it and looked at it.
Now make a bigger straw and try to stiffen the surroundings with the same material as the furnace wall.
"Oh? You're doing something interesting." But that's no good. If only the metal part melts, it will clog the wind hole. "
Oh, why don't we make this out of the same materials as the furnace walls?
When they heard that, the dwarves roared with a hard face.
"Of course I tried, but after using it for a long time, it gradually collapses." So, the metal melts and comes out of the outlet, but if a part of the furnace wall breaks down, it doesn't melt, so it gets clogged. Then we have to shut down the furnace and put out the fire. If that happens, I won't be able to use the furnace for two months. "
Mixed in a sigh, the dwarf replied so.
After the fire is extinguished, it is cooled, and then it enters the furnace to clean and repair it. The wind hole will also be rebuilt. It seemed that it would take a lot of time to get into the fire.
That said, it's a hassle to shut down the furnace and rebuild the hole every six months.
"... All right. Then let's study the wind tunnels that don't need to be rebuilt."
Murmuring that, Habel and the others immediately reacted.
What?
It can't be that easy.
"I think the dwarf nation has been studying for hundreds of years."
Listening to the skeptical gaze and words, I laugh in dismay. [M]
"I could do experiments that I couldn't do in a dwarf country."
After that, the havels hardened for a while and shouted.
