TotalBoat Clear High Performance Epoxy can be used to adhere metal to wood.

We recommend thickening the epoxy with TotalBoat Silica Thickener. Only add thickening agents or filler materials once the resin and hardener components have been blended thoroughly. Silica, including colloidal silica and fumed silica, acts as an adhesive thickener, adds sag resistance, is white in color, and will impart a milky color. Silica is also commonly used to prevent porous substrates from absorbing epoxy.

Be sure to follow the preparation instructions specific to the wood and metal type, which can be found here.
