"Who was next"

"You're an expert in stone molars."

When I check the order with Claudio, I get an answer right back.

"Ishimori."

Rotating stone molars are used for powder production using water wheels.

In the case of vertical water vehicles, the rotating stone molar can be moved by rotating horizontally using gears and the like.

If this is a horizontal water wheel, the difficulty is reduced by using the water wheel rotation as it is.

"What announcement will you make?"

To be honest, I don't know much about stone molars.

For once, the principle was confirmed in a small stone molar, but the machining required hardness and precision.

The three experts who came forward to make the announcement were quite small when compared to surveyors and waterwheel experts.

In your hands, you look like you have some stones, fleas and other tools.

"Ladies and gentlemen, my name is Pilhonen, and I am a stone locksmith. I was called to a seat like this and honestly worried a lot about what to say. Because I'm plain nature like this, I'm going to start by introducing our work without decorating it as it is."

Other experts seem to have taken a liking for Bill Honen's undecorated attitude.

Experts are a thorough gathering of practitioners, so they weigh their work more than flashy and strong words.

The expression of the opinion that the only way to introduce a job is to introduce a job, is also the words of those who take pride in their own work, saying that introducing a job is enough to make them know who they are.

When Bilhonen signaled, a chunk of round rock rolled from behind the seat making a gobbly, low noise.

Will it be nearly 50 cm in diameter?

That's two.

When those two cross sections were arranged so that they could be seen here, Billhonen began to explain.

"This stone mold is a stone mold in production that was at my place. It was cancelled at the convenience of the other party, and I brought it because it is just right for this kind of use. It is very heavy, so I used a riverboat, but I had a hard time transporting it by road. Like the deputy said, construction is convenient when it's along the river. I felt it in me."

There is a low laugh in Bill Honen's explanation.

Indeed, the stone molars are heavy. In the first place, it is heavy and natural because it is the role of stone molars to mill wheat by its weight.

If there is a construction site along the river, stone mortars produced in distant workshops can be brought directly in by boat.

In other words, manufacturing and transportation costs can be lowered.

I am convinced that the emphasis on this world, on water transport, without trucks, cranes, etc., was not wrong.

"Now, the stone molars are made up of two parts. It's the bottom molar and the lid molar. The bottom molar is fixed to the ground and the lid molar rotates over suspended from the top. What I want you to see here is the section where the molar contacts."

When Bill Honen turns it so that it can be seen by one audience of stone molars, everyone's gaze concentrates.

The stone molar is beautifully carved with geometric lines that run from the center to the outside.

"In this way, the muscle (zipper) is dug in the stone molar to carry the wheat outside the molar while it is being milled. When this muscle is beautifully and regularly carved, it is said that the flour can also be grained. As soon as the muscles are too fine, they are less polished and more conspicuous, and if the muscles are too deep and coarse, it affects the powder that can be done."

Everyone listens to Bill Honen's specific description.
