Dennis as usual has given the best advice. On the wood adjoining silver there is no way I would trust a glue to join the ends together. You would either have to solder a pin onto the silver and drill into the wood and glue or set the wood into the ends of the silver with a bezel which is quite advanced. I’m assuming that you’ll be turning the wood on a lathe for the sandwich version with sheet silver in between? That could either be glued or glued and riveted. I’m a fan of rivets!
