SSJ Complete

      SSJ making is completed. I set-up high-E is 1.9mm at 12F, and Low-E is 2.7mm at 12F. This guitar showed nice over tones with a bit brighter tonal character than the rose wood. This is due to the Padauk B&S and Adirondack top combination. Tonal character is in between RW and Mahogany. This guitar has very responsible touch. I installed the D'addario EJ16 phosphor bronze set. This set has quite bright tonal character. So, it may change the tonal character with other strings set. However, EJ16 is my reference string set for testing a new guitar. 

     The SSJ is in a Guardian CG-044-HD case. Fitting in the guardian case looks very good with nice holding. Before shipping this guitar, I will replace strings to a new set. I also will have a polishing session before ship this guitar.

Wet sanding, Polishing, and Bridge install

      2000-grit wet sanding and polishing works are done. I take only one 2000-grid wet sanding session after the final coat of the EM6000. 2000-grid wet sanding requires a little bit longer sanding time to make a perfect smoothness. However, this method makes the best polishing quality, due to the smallest possible sanding scratches. If I use the 1200-grid session, the following 2000-grid session is not able to remove the 1200-grid scratches easily. Therefore, I only have one 2000-grid session after the final coat spray. 

     I also completed the bridge installation. I have been using the Tight bond for the bridge gluing. I also have been using the vacuum clump for the bridge clamping. First clumping is approximately 7-minits. Then, I clean the excess glue using a wetted cotton fabric. I also remove the masking tape at the bridge portion. So, I can clean the surface near the bridge edges. Then, I resume the vacuum clumping additionally half hour. This bridge assembly process is the best for me.

Final coat spraying

 I completed 8-layers of the final coat apply. I applied four coats in the day one. In the day two, I filled some missing spots for the pour filling. I did three times of Epoxy pour filling sessions; however, there are some missing sots. I mixed between the EM6000 acrylic finish and the silica filler for creating a thick filling material. I filled all missing spots with this custom filler. In the day three, I took a 1200-grid wet sanding for the surface leveling. Then, I back to the additional 4-more finishing material apply. Total layers are eight. I have been using the Emtech EM6000 water base acrylic finish. I also applied the EM6000 to the bridge. I will wait 7-days for the final coat curing. Next week, I will start wet sanding and polishing work.
