Underneath the epoxy that was mixed with colodical silica is the 1/4 inch balsa. Once I placed and pressed the skin back on the overflow of epoxy would spill out. Also Note: I spread epoxy/colical silica on the skin before assembly.
80 Pounds of salt pressed and kept the skin in place.
One side with new balsa and the skin put back on. This side will next have the cuts beveled and glassed over with cloth.
