Bonding Aluminum to plywood and/or veneers
got 2 questions regarding aluminum and wood.
now they are not the usual 2 items glued together but my project requires that they be fixed.
first project is a 60" x 26" surface that i need 1/8" thick aluminum 3003 glued onto a 1/2" mdf core or veneer core plywood.
i've read folks having some success using epoxy to a well prepared and etched aluminum surface... but my concern is their different reaction to temperature changes.
the flat surface will be kept in my basement, at stable <50% humidity... and temperature is pretty constant throughout the year.
the 60x26" sheet will also be fastened to a table top using countersink machine screws at 12" x 12" intervals.
so, should i just forego the gluing or instead of epoxy, use something more flexible such as contact cement?
secondly, i have some paper backed veneers that need to be fixed onto aluminum sheets that are <1/8" thick. should i also bypass the epoxy here?
all applications are for indoor products.
thank you in advance for your replies.
