Final polishing

I have done final polishing work and bridge making. Both nylon models are completed final polishing with 2000-grit water paper. Bridges are also completed three coats of Shellac apply with a light sanding session. Next week, I will do the bridge install, fret wire leveling, and oil finishing for the fingerboard. So, both guitars will be able to complete before the La Guitarra California 2015. I will show both guitars for the festival. La Gutarrra will be in between September 25 and 27. If you are closer to the San Luis Obispo, please come and check those guitars.

Finishing work is done

Final spray for the finishing work is done last week. I also finished the bridge making this week end. Those guitars need final sanding and polishing. I will start the sanding work this week. Water based Acrylic finish is fairly soft for the sanding. So, I will star the 1200-grit for the Orange peel removing. Then, I will take 2000-grit sanding. Then, I will take hand polishing. I do not use the machine buffing, because the machine buffing makes heat that damages the final coat. Bridges are made by the Madagascar rosewood. So, it looks exactly like Brazilian rosewood. Next week, I will start final assembly.

Filler apply and Arm rest making

     Filler apply is started. I have been using an Epoxy with Silica powder mix as a pour filler. This works pretty good for Water based Acyclic finish. Epoxy filler is also very easy for sanding. I still need approximately 4 hours for one sanding session before final coat apply. However, it is relatively short compared with conventional filling process using classic sanding sealer and filler combination. After apply the Epoxy filler, the body and the neck show beautiful flames. Myrtle body and Maple neck are amazingly beautiful already.
     I also completed the arm rest making. The arm rest is made by flamed maple. My arm rest has a floating design that is mechanically isolated from the top. This design maximizes the top vibration. I will black die the Maple arm-rest before final coats apply.

Fret wire install and final sanding

Fret wire installation and final sanding are completed. So, all wood working jobs are done. Next week, I will apply Epoxy filer and sanding. It might need two sessions to fill the Mahogany neck. Myrtle is able to fill one coat, and Malaysian black wood is also need one coat. However, mahogany/Spanish ceder neck requires two coats with sanding sessions for the pore filling. During the Epoxy filling sessions, I also will make arm rest for both models.
