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.

Neck Making part 1

     I am making nick for the classic model. I made three neck blanks to select the best design. One neck blanks has the 5-ply configuration that is made from Spanish ceder + African BW + Ceder + ABW + Ceder. The other two necks are seven ply configuration that is made from Ceder + Block died maple veneer + Maple + Ebony + Maple + Black died maple veneer + Ceder. I have been using laminate neck for my guitars, because the laminate neck has the best stability and the best sound quality. My neck has the unique V-joint between the beck blanks and the head. Vee joint requires super precise trimming work. However, this joint makes the best beauty for me.
     I also made three different heads. One head is made from Catarox. Catarox is a super heard material. Other two heads are made from Spanish ceder. I am still thinking witch neck blanks and head combination will use for this Classic project. However, I already decide the neck material, and I will use the seven ply neck.

Side making

Side making for the Maple classic model is complete. Strongest and lightest configuration is required for the guitar side. To make the strong side, I have been using a laminate technique. My side is made by Maple and Yellow ceder laminate. Lining is also made by laminated Spanish ceder for the top side. Top side requires very stable structure for supporting the sound board. My neck side block has a very wide extension to support the finger board. This extension is designed for supporting two carbon fiber rods installation. Those carbon fiber rods makes another level of improvement for the guitar side. Wide extension also prevents the sound board clacking issue. This problem is very commonly observed in old classical guitars. Wide neck extension is able to avoid future issue.
