I'm making 6 large drawers (514x720x150mm) for the bedroom, with 20mm thick walnut sides (didn't realise quite how expensive that timber would be...! ) and 8mm plywood for the base.
The drawer sides are joined with mitre lock joints done with a router, and the base will fit into 8mm deep dados in the drawer sides.
I'd like to glue the base into the dado grooves, and I realise that plywood is dimensionally stable, what I'm not sure if is whether walnut is sufficiently stable for me to glue the base in snugly without fear of damage from expansion/contraction?
