Abstract
A fiber glass fabric reinforced wood sound board for a guitar is made by placing a sheet of wood in a shallow mold cavity with a layer of fiber glass fabric overlying an associated surface of the wood sheet, spreading a layer of liquid resinous compound over the layer of fabric to impregnate the fabric, providing a plate having a smooth surface, positioning the plate with its smooth surface in face-to-face engagement with the layer of liquid impregnating material to provide a substantial closure for the mold cavity, drawing vacuum on the mold cavity, and curing the liquid resinous material.
