Thatch Roofing in Miyama-cho, Kyoto Prefecture 茅葺屋根 京都府美山町

 Miyama-cho in northern Kyoto Prefecture is one of the few remaining locations in Japan where the tradition of thatch roofing continues.  Other popular locations are Shirakawago in Gifu Prefecture and Gokayama in Toyama Prefecture.
 Miyama is home to a number of professional roof thatchers, including one of Japan's largest roof thatching companies, Miyama Kayabuki. Another Miyama organization promoting roof thatching in Japan is Kayabukiya.
 This past summer the Miyama Thatch Roof Resource Center was re-thatched by Nishio-san.

Modifying and Securing Gypsum Mouldings

Using the straight and circular mouldings described in the previous post, the following describes how to cut and secure gypsum mouldings.

 

 Measure the distance of the desired moulding and cut the moulding at a 45 degree angle using a miter box.

 Check cut to ensure a 45 degree angle

Mark finish level with an ink-line

 Check fit of all mouldings, preferably at the same time to ensure clean joints

 

 Treat the back of the mouldings with a sealer to slow the absorption of moisture

 Paint on with brush

 Prepare gypsum based bonding plaster

 Add methylcellulose to improve workability and delay hardening

 Dry mix GL bond and methylcellulose, then add water

 Firmly apply a thin coat of GL Bond, then apply in thick globs

 Wet plaster, firmly apply a thin coat of GL Bond to the base coat, and then set moulding

 First the bottom, then sides

 Lastly, top.

 Check joints

 Adjust joints if needed.

  Set the circular moulding: In this case, equal spacing on sides and top.

 Ensure circular moulding is at the same level as the surrounding mouldings

 Check horizontally and diagonally

  Imperfections can be corrected with paintbrushes and plaster.

 Dip the brush in water and the edge of the gypsum powder, and correct the moulding

 

 After correction

 

 10mm for brown and finish coats

Circular Gypsum Moulding

Modifying the same moulding form from the previous post, the following describes how to create a circular gypsum moulding.

Cut thin metal strips and wrap around a radial handle.

Secure the metal strip: Pierce the metal and handle with a nail, and bend the nail on the opposite side to secure the metal strip.

Punch a hole in the metal strip to allow the radial arm to rotate around a central peg.

Intall the central peg: In this case a nail is pounded into the table and the nail head is cut off with pinchers.

Radial arm and central peg

Determine the desired radius of the circular moulding and attach radial arm.

 Draw outline of circular moulding

 Cut string for circular moulding to improve tensile strength

 Mix gypsum and secure string between moulding outline

 Pull mould form in circular motion

 Repeat

 After completion, remove circular moulding similar to the moulding described in the previous post.
