365 Measurement and Formation

 Steel becomes harder than normal when it is enchanted with the cheat's ability. The hardness contributes to the sharpness of a knife or the durability of a shortsword.
 Hardness is also important for armor. Of course, hardness alone is brittle, so a certain degree of flexibility is also necessary.

 The day after Helen asked me for advice. The next day, after Helen's advice, I set to work on the armor. Most of the deliverables were ready, and it wouldn't be a problem if I spent a few days working on other things.

What about Rike?
"I'll watch.

 "I'll observe." Rike said he didn't have anything urgent to do. He said he had no urgent work to do, so he should ask for a day off, but he didn't.

Uh, well, can you measure Helen for me, please?

 Helen, Rike, and Anne, who had been beckoned to me, retreated toward the house. There's no point in measuring her here. .......
 Anne was probably helping. Helen is tall, so it would be better to have Anne, who is also tall, help her. I asked Rike to help because she knows how to do that kind of measurement.

 In the meantime, I started preparing the sheet metal for the breastplate. The sheet metal is of a certain size, but it is not enough to make the breastplate.
 The sheet metal is rectangular. Stack two of them on top of each other, heat them, and beat them on an anvil. They do not need to be tightly adhered to each other, so they are beaten without borax.

 When the sheet metal becomes twice as wide, make a crease in it with a soldering iron, and then bend it. Now that you have a piece of sheet metal that is twice as thick, add another sheet of sheet metal to it, and repeat the process of heating, beating, and folding in the same way.

 When we finally start to stretch the sheet metal that we've folded several times, or rather, that we should call a lump of iron, Helen and the others come back. There shouldn't be too many places that need to be measured, but it took quite a while.
 We don't use it often, but we have a little paper and writing utensils for just such occasions. If I had used a cheat, I could have made the shape accurate just by looking at it, but I left the fact that I had measured it to claim that I had done it.

 The paper he handed to Rieke had some numbers on it. I heard that the units of weights and measures are slightly different between the Kingdom and the Empire, but the scale in my house is the Kingdom's, so the numbers must have been measured with it.
 It seems to be correct even if I check it with a combination of installation and cheat. I glanced at the paper and took out a lump of iron from the fire, which was just getting hot.

 From here, I made the shape. There are two types of armor, one with separate chests and one with separate chests, but this time I'm going with the one with separate chests.
 In order to make it function as an armor, the center part should be thicker and thinner toward the edge.
 First of all, stretch it out on a regular anvil, and when it is about 4cm thick all over, make a steel plate that is about 2-3cm thick in the middle and a little thinner at the edges. The thickness of the steel plate should be 2 to 3 cm in the middle and a little thinner at the edges.
 Finally, it was time for lunch before forming the chest part ....... I paused my work.

How do you like it, master?
"Well, steel is steel, so there's no big problem at the moment. Changing the thickness was not as difficult as I thought it would be. Changing the thickness wasn't as hard as I thought, though the molding of the chest may become a problem in the future.

 Rike asked me this as we were leaving the forge for lunch, and I answered him honestly.
 In fact, even though I needed to change the thickness for now, it was nothing more or less than making a steel plate. It's not a very difficult task.
 My answer seemed to have met his expectations, and he didn't ask for any more details.

 Shaping a curve is a little difficult with an ordinary anvil. I brought a small, round anvil from the corner of the forge and set it next to the usual anvil.
 I placed the part to be bent on it and beat the steel plate as if it were wrapped around me.
 I had to shift the position of the hammer a little at a time, otherwise it would actually be wrapped, so I shifted it to get the shape I wanted and swung the hammer down again and again, making a high-pitched clanking sound and sending off bright red sparks so that it would be filled with magic power.
 Slowly, slowly, the steel plate changed its shape, as if in response to my wish.
