[QUOTE="DaleH, post: 482642, member: 15636"] Yes =D> , that is called the 'mushroom' technique and was popularized by West Systems when they 1st developed or applied epoxies to wooden boats or to FRP boats with wood used in the construction. Epoxy cures and adheres via a [u]chemical bond[/u] and the intent of sandwiching a material between 2 layers of epoxy in effect also makes a [u]mechanical bond[/u] or 'locking feature' with the parent material. That actually is a technique that should always be employed with epoxy for the best bond! Examples include roughing up the surface/hole prior to gluing, or like where I've used it to repair broken forends on rifle stocks, I'll embed a graphite arrow shaft in a hole through to join the 2 pieces.
