The woods that will be used in the 12-string guitar. Sitka “Bear-claw” Spruce sound board and Macassar Ebony back and sides
In Phase 1 the raw woods for the guitar sound board, back and sides are sanded down to their final thickness. The sound board and back are aligned for symmetry and glued to form a single board.
A home-built thickness sander is used to reduce each board half down to a uniform thickness of about .1” to .11”
The joining edges of the sound board must be sanded perfectly straight on a sanding stone.
When hand held together against a strong light, if no light can be seen to creep through the joint, the edges are straight enough to glue together
