How to make it

Safety

Wear eye and hearing protection and a dust mask at the router, and always anchor tall furniture to the wall.

  1. Step 1: Cut the parts
    1

    Cut the parts

    Cut 2 sides at 47 in from one 8 ft board. Cut 3 shelves at 31 in from the other, and a 4th shelf from the 4 ft board. Cut the toe kick at 30 1/2 in.

  2. Step 2: Lay out both sides together

    Lay out both sides together

    Clamp the sides edge to edge, inside faces up, bottoms flush. Mark the bottom edge of each dado at 3 1/2, 17 3/4 and 32 in from the bottom.

  3. Step 3: Test the bit

    Test the bit

    Rout a test dado in scrap and slide a shelf in. You want a snug push fit, not a hammer fit.

  4. Step 4: Rout the dados

    Rout the dados

    Clamp a straightedge to guide the router. Cut each dado 3/4 in wide and 1/4 in deep in 2 passes, across both sides at once.

  5. Step 5: Rout the top rabbet

    Rout the top rabbet

    Cut a 3/4 in wide, 1/4 in deep rabbet across the top inside edge of each side for the top shelf.

  6. Step 6: Glue up the case

    Glue up the case

    Glue the shelves into the dados and rabbets. Nail through the sides into each shelf, then check that the diagonals match.

  7. Step 7: Add kick and back

    Add kick and back

    Glue the toe kick under the bottom shelf, set back 1/2 in. Cut the back to 32 x 47 in and nail it on every 6 in. The back squares the case.

  8. Step 8: Finish and anchor

    Finish and anchor

    Sand, condition, stain and add 3 coats of poly. Anchor it to a wall stud with the anti-tip kit before loading books.

Edie's tip

Pine 1x10s often measure a hair under 3/4 in. Measure yours and match the dado to the board, not the label.
