Make several copies of the exploded drawing and carefully cut out the elements with a razor or exact knife.
Cut a piece of thin fiberglass sheet larger than the design to be used as a scrim backing and tape it down to the piece of melamine.
Starting with one of the larger paper elements, glue it to a piece of the wood. Select a piece that seems best to match the design. Look closely at the grain, direction of the grain, color, and etc. in making your choice. Cut this piece of the design out using a jewelers saw frame or a scroll saw. Using jewelers files, refine the edges to exactly duplicate the outline of the drawing, keeping all edges at a 90 degree angle to the surface. Glue this first piece to the fiberglass sheet with super glue. Continue making up the other elements an gluing them in place until the whole design has been assembled.
