Prepare for Close Box

The side braces are ready to be glued.
In the preparation of the side braes, my saw teeth was destroyed.
To glue the side braces, they need to be inlet into the lining or peones itself.
This is to prevent the side braces from exerting weakness on the sides as it is basically a cross brace on the sides.
Luckily this is ABW which is a very stable wood.

Next is to prepare the backing for the sound port.
One thing have to be sure is not to mess up the position of the sound port.
It should be done at the side facing the player i.e. bass side.
Although one can argue to open 2 holes, but more sound port will cause degration to the low response of the sound.
So need to limit how many and size of sound port open.

The veneers were glued to the back of the position of the sides where the port will be opened.
A curved caul was made to ensure the veneers are clamp properly.

Next will be the cutting of the sound port itself.
The commissioner of the guitar prefers to have a star shape sound port
So but the problem of having a star shape is that it's not symmetrical.
So there need to be some form of orientation.
So I was deliberating the orientation of facing the player or straight with respect to the guitar.
Finally decision was to take reference to the guitar.

The hole was cut and file to shape nicely.
