Laminated linings out of Spanish cedar install.
I laminate these using the sides propped in the mold as a form. Packing tape is on the inside of the sides so I can remove the linings once they have set up. Then the profile is sanded onto the inside edge and they are finally glued to the side of the guitar.
In the lower bout the linings are wider than in the upper bout because there will be an arm rest bevel there.
