Classical Project Complete

     I completed the classical guitar making project. I installed strings in 11/23/2019 first time. Strings action over the 12-fret wire is 3.4mm for the low-E and 3mm for the high-E. This is quite low action setting. I installed the D'Addario EJ45 normal tension strings. This guitar has been improving the sound quality day-by-day. Now, I have good confidence that this guitar has very nice bright sound character. Low-E string has very power full sound. I feel strong vibration in my stomach, when I hit the low-E string. This result is due to the graphite rod reinforcement in the last photo. Those carbon rods braces hold the neck very tight. Also, those braces are able to avoid future deformation issue for the neck angle change. Carbon braces are super light weight; therefore, the additional weight penalty is very minimum. I am very happy with this results.
     Please enjoy posted photos for the completed Classical guitar. The guitar specifications are shown in below.

Binding: Ebony
Tuning machines: Gilbert
Head plate veneer: Ebony (top and back)
Armrest: Black dyed maple

Finishing: Shellac (top) and Water based acrylic

Final Assembly

     Classical guitar project is completed. I installed a bridge, an armrest, and tuning machines. My bridge has 12-holes for the string install. The 12-hole bridge is able to make the highest possible strings angle to the saddle. This makes the brightest possible sound character due to the highest possible tension. The bridge has couple of Shellac coatings with steel wool mat finish. The bridge was installed using the vacuum clamping system for the best result. Tuning machines are Gilbert tuners. For me, the Gilbert tuners are the best on the market.
     This guitar has the Shellac finish on the top. Rest of surfaces are water based Acrylic finish. Shellac finish on the top makes brighter sound character. I installed D'Addario EJ45 normal tension strings.

Neck Shaping

I have been working on the neck shaping. First, I make the thickness profiling. This neck has 22 mm thickness at 0-fret and 24 mm thickness at 9th fret. The top of the neck profile becomes the reference plane. Second step is partially tapering the cross section. This shape becomes the other reference plane for my neck. I will never touch those two reference plane. This technique is able to make precisely straight neck. I already installed the finger board and the neck heal cap. The heal cap is Ebony and the Ebony heal cap matches to the ebony neck center laminate.

Neck Joint

Neck joint is complete. Neck heel shape was done before the neck joint. I selected Spanish style heel shape. This guitar is a traditional classical guitar. So, I selected the classical design. My neck joint is the mortise joint. After complete the mortise joint, I adds two wooden dowels to avoid neck dislocation issue. This method is the best for me to precisely align neck angle and precise fitting. Also, I installed a square carbon rod from the neck top to the body at the finger board end. You may see the maple cover over the carbon rod at the center of the neck. This rod improved neck robustness against strings pull. I will have the neck shaping work and the fingerboard install next week.

Binding install and Neck Joint

Ebony binding install is complete. Ebony binding makes beautiful contrast to the Maple body. This body also has an Ebony center strip in the back. After, install the neck. Laminated neck and the back center strip match very well. At this moment, the neck joint is temporary. It requires a lot of time to accomplish precise alignment for the angle and fitting. Also, before the final neck installation, the neck requires the shaping work. It still requires a long way to complete this guitar making project. 

Neck Making Part 3

Neck making has more progress. Neck head veneer for the top and back are installed. I selected Ebony to match the Neck laminate material. Also the top and back veneer makes better re-enforcement for the Vee neck joint. I also took photos with machine head. This time, I will use the Gilbert machine head. For me, this is the best machine head for nylon strings guitarist. This machine realizes super good tuning stability for real processional guitarists. This neck has a 650mm scale African black wood fingerboard. ABW is the best fingerboard material, because ABW is one of the hardest wood species. For me, Ebony is way too soft for the fingerboard application. ABW is very hard to work for the finger board shaping. However, after polishing the ABW, it makes super smooth surface for the best play-ability.

Neck making part2

I completed neck head making and Vee joint. Neck head already has holes for machine head. I made Vee joint cuts for the neck blanks and the head. Then, glued together between the head and the neck blanks. Now, the neck is ready for shaping. Before the neck shaping, I need to cut a finger board, and head veneer gluing. I will use Ebony for the peg head veneer to match the ebony neck center laminate.
