Don't remember one where the current passed THROUGH the glue, but
there are any number of processes where the glue is set by using RF
current for heating, plywood aircraft were done that way in WWII and
the sulky company my dad worked for cured their laminated cart poles
that way. *Melamine resin glue and urea-based glues were a couple of

still laminated that way.
