A new role for nails in project assembly
To assemble tricky-to-clamp projects, say an oval frame or a three-sided flag box, use nails to temporarily hold workpieces in place while the glue dries. First, dry-assemble the project parts on a piece of ¾" plywood. Once you’re satisfied that everything fits, apply glue to mating surfaces and drive finishing nails ¼" or so into the plywood to hold the workpieces in position. Use painter’s tape or waxed paper to prevent the assembly from sticking to the plywood. Gently remove the nails after the glue dries.
