5. Trace the
wastebasket onto the 3/4-in. plywood (W). Draw a second line about 1/2 in.
inside the traced outline. Drill a 1/2-in. starter hole and cut along the

6. Glue and nail the slats and spacers together to
make the grate. Drill 1/16-in. pilot holes for the nails to prevent splitting
the wood. Spread water-resistant glue on both surfaces and nail the slats and
spacers together with 1-1/4 in. finish nails. Clamp the completed assembly with
bar clamps and allow it to dry overnight. Trim the 23-1/2 in. grate to 23 in.
with your circular saw or table saw and sand the edge smooth.

8. Attach the fixed bench-top pieces (Q) with 1-1/4
in. Screws driven up through the bench-top cleats (U). Secure the bench-top
ends (P) and bottom shelf boards (V) by driving 1-1/4 in. screws through
predrilled and countersunk holes. Conceal these screws with wood plugs glued
into the recesses. Sand the plugs flush when the glue dries.
