Island Forge: Part 3 – Roof

This series of photo essays will document the preparation, construction, and set up of a simple swordsmith style kajiba (鍛冶場, forge building) from the ground up. The main inspiration for aesthetic, form, and technique is the humble Japanese inaka farm building style of a century ago.

Framing & Sheeting

The roof was assembled on the second of three days of clear weather between snowfalls and the sheeting was installed on the third. Galvanized metal “totan” style sheeting is attached to horizontal purlins running across the rafters.

Still plenty of finishing work to be done but the main structure is standing and covered.
The next steps will be to enclose the sides with yakisugi.
