Basically, 1/16" thick slabs of wood are bent 14 degrees to make the head/neck transition. Then fiberglass is embedded in a rigid glue between the wood laminates. I use the urethane-glue-known-as-Gorilla because of its rigidity and availability. An epoxy would also do well here, but not necessarily better; it can be hard to find an epoxy of the appropriate viscosity, but Gorilla glue can be found anywhere.
This method eliminates the deadly grain run-out on the head/neck transition, which is the first spot a stringed instrument will snap when dropped or mishandled.
The fiberglass will handle most of the stress of the strings; this allows use of a lighter wood, creating a lightweight but extremely rigid neck, less fatiguing to hold, less susceptible to climate changes and ready for a lifetime of music.
