Carbon rods and Top fitting to sides

     Carbon rods for the top deformation prevention were installed. I have been using 10mm Carbon rods. Weight almost nothing for the Carbon rods. However, this pair of rods improve body robustness against strings tension. Virtually, all steel strings guitars require neck re-setting work in 30 to 40 years of use. However, Carbon rod installed guitar is virtually maintenance free from the view point of the neck action change due to the body deformation..
     I also completed top fitting to sides. Before fitting the top, I also completed the scalloping work for the X-bracing top. Jazz nylon model is more straightforward for the fitting work, because of the simple bracing pattern. You may see the beveled armrest for the Jazz nylon model. This time, I installed the beveled armrest on the Jazz nylon model. Usually, I do not use the beveled armrest for the Nylon models. However, I installed this particular model for a guitar show.

Solid lining install

     Solid linings including beveled armrest were installed. Solid linings were made from three layers of Spanish Ceder. Cur-a-way portion and beveled armrest portion were made from solid Spanish Ceder piece. Those solid linings make significant sound improvement. Although solid linings require a lot more extra time for making compared with the conventional kerfed linings, I have been using this technique. Slid lining are also invisible from outside. I still want to install them. Sound quality improvement techniques are usually invisible from outside. However, I have been installing all of possible techniques such as the double layer sides, solid linings, and lattice back bracing.

     Next week, I will install Carbon fiber rod braces for the body deformation prevention.

Radiusing sides

Radius-ing for sides has been done. I have been using the 30' radius for the top and the 12' radius for the back. For the radiusing, thickness for the side should be accurately controlled  to obtain designed final thickness. So, this process is relatively tricky. I will use planes quite actively to speed-up this radiusing process. After complete the side thickness profiling and radiusing, solid linings will be installed.
