Carbon fiber rod install and the sound board final shape

     I completed carbon fiber rod install. Carbon fiber rods are for preventing the body deformation over long time. Also, the carbon fiber rods improves the side rigidness for crisp sounds. Laminated side, solid lining, and the carbon fiber rods reinforcement are the best recipe for the best sound board vibration. This rock solid side maximizes the sound board vibration with minimum enagy loss. This is the most advanced steel strings guitar configuration.

     I also completed the final shaping for the sound board. I have tried different bracing patters. Now, my bracing pattern is quite traditional shape. I think the X-bracing is the best bracing design for steel strings guitars. After complete the sound board shaping, I applied two coats of shellac for improving the moisture sensitivity. I have been using the shellac coating for inside of my guitars.

Beveled armrest and solid lining

I installed the beveled linings for the armrest and the neck joint. I also installed the solid lining. Beveled linings is made from Spanish cedar. The solid lining is made from three layers laminated mahogany. Making the beveled lining is a bit tricky work. I always use a band saw for the 45-degree angled cut. Also, glueing work for the beveled lining is a tricky work. I created custom designed cauls for holding the beveled object. This device works pretty good for this tricky work. The sound board side lining install work is completed. Next week, I will install carbon fiber rods for improving the body rigidness. 

Block making and side assembly

I made head and tail blocks using Honduras mahogany. Also, I completed side assembly. This MD model will have a bolt on neck joint. Also, the MD will have a Carbon fiber rod body reinforcement bracing system. So, the block making is a little bit complicated work. Head and tail blocks were required to add many holes for the neck joint and carbon fiber reenforcement rods. 

Before installing blocks, I precisely shaped blocks to match to the side shape. Now, the guitar side assembly is done. I will shape the side thickness to the designed number. Next step is the lining and the kerfing install.

Side bend and laminate work

Side bending work was completed. Bended African black wood and Yellow cedar were epoxy laminated for the MD body shape. Both African BW and Alaskan yellow cedar were thinned to 1.5mm thickness. I have been using an old electrical lump based bending machine. The machine still works good. For the Epoxy laminate work, I use at least 10-pcs of cast iron heavy duty C-clumps. Laminated side showed a perfect flatness and shape for the MD body.
