I am building some telescoping covers. They are traditional metal on top of a wooden framework with plywood rabbeted inside the framework type. I plan to use galvanized staples through the sides of the cover and am not sure if this idea is better.
A woodworker, but not a beekeeper, suggested I use an adhesive, such as liquid nails, construction adhesive or other type of "glue" for metal/wood surfaces, instead of penetrating metal fasteners, such as staples, screws and nails, to hold the metal top onto the telescoping cover wood. This would be an adhesive on the top side of the plywood and bottom side of the metal. It would be away from the bees provided it doesn't leach through the wood. It would be applied as a solid perimeter around the top of the framework and maybe an "X" or so shape through the middle of the plywood. The adhesive would also make a complete seal around the perimeter which would block ants or other insects from nesting between the metal and wood (a minor nuisance I've occasionally had).
He said the advantages would be that it would (1) hold the top solidly onto the framework, (2) result in no piercings of the metal making the whole piece less vulnerable to moisture and rot, (3) would last "forever" because the adhesive is protected from the weather; or at least longer than metal fasteners that might fail themselves or that the metal immediately around the fasteners might fail. I did discuss with him the hot/cold temperature fluctuations telescoping covers experience.
Is this a good idea? If so, are there any recommendations for an adhesive?
