Caution “Kiura is not exposed to the public”
The properties of the members of logs differ depending on where they are cut out.
For example, when the board dries, the Kiura(heart-side) protrudes. If you do not know this property and provide a groove for the Sikii / Kamoi, which is a board material, on the Kiura, the fittings will be pushed up and down, and the opening and closing will be hard. Be sure to install the groove on the Kiomote(sap side).
