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.

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.
