Roofing

One of the events of the 2011 Takenaka Carpentry Tools Museum Exhibition [Roofing - Roofing made of grass and wood] was held at Gallery A Quad on the 1st floor of the Tokyo head office of Takenaka Corporation. Lecturers are members of the National shrines and temples and other roof construction technology preservation society.

First, how to make a cypress bark that had been peeled off from the cypress as a roofing material (this process is called "Koshirae"), a craftsman demonstrated I got it.
There were many questions from customers, and the craftsman carefully explained the question.

Next, there was a demonstration and experience of fastening the koshira cypress skin with bamboo nails using a roof hammer in the same way as when roofing the roof.

When roofing, the craftsman puts about 30 bamboo nails in his mouth, puts them out one by one, and fastens them with a roof hammer.
First of all, it's a demonstration of a craftsman.

Next, under the guidance of a craftsman, I had the experience of actually hitting bamboo nails.
Rotate the bamboo nails in your mouth well in your mouth and go out, pierce the sharp tip into the cypress bark, and hit it 3-4 times with a roof hammer.

It looks like after a bamboo nail is hit.
The bamboo nails that have been hit can be fastened so that the head is moderately crushed and the roofing material does not emerge.

It looks like the whole venue.
Everyone was very popular because they saw what they couldn't usually experience.
We were blessed with good weather on the day.
Thank you very much to everyone who came to the museum and to the lecturers who responded for a long time at the National Preservation Society for Roof Construction Technology in shrines and temples.
