Project Resources


This project requires, a bifold door kit, one 36-inch furniture round, and a couple of dowels. Build it before lunch, paint it, and you can install it before the weekend is over.

Make the Shelves

Step 1

Cut two 1 x 4 scrap boards 24 inches long and clamp them to the surface of your workbench (Project Diagram, Drawing 1). With the help of a framing square, adjust the boards to form a 90-degree corner.

Step 2

Mark the disc.

Set the 36-in round pine disc into the corner of the two boards and draw a line on the disc and on the boards where they meet (Project Diagram, Drawing 2), these points will be 90 degrees apart. You will find the center in a later step.

Step 3

Rotate the disc 90 degrees until the first mark on the disc meets the second mark on the boards, and then draw the new intersecting point on the disc (Project Diagram, Drawing 3).

Step 4

Rotate the disc a second time and mark the fourth point. You may need to make some slight adjustments to the marks to get them perfectly spaced.

Step 5

Cut the round into four shelves.

Draw two lines across the disc to form four quadrants (Project Diagram, Drawing 4). Draw a line 1/2 inch from each side of the two crossing lines and place a strip of painter’s tape between them. Jigsaw the round along the edges of the tape to make four equal-size shelves. Sand the faces and the cut edges of the shelves with 180-grit sandpaper.

Good to Know

Don’t worry about getting the edges perfectly flat after cutting them with a jigsaw. Because you will be painting the doors, you can use construction adhesive to bond the shelves to the doors. After the shelves are glued in place, fill any voids with paintable caulk before adding the paint.

Assemble the Shelf

Step 1

Add square dowels to the edge of a door.

Remove all hardware from the bifold doors to separate them. Drill pilot holes, glue, and use 2-inch screws to attach the two 1-inch square dowels along the edge of a door flush to one door face (Project Diagram, Drawing 5). When aligning the dowel with the face of the door, place the dowels so they are flush with the sides of the doors that have no holes left by the hardware.

Step 2

Glue and clamp the door with the dowels to the remaining door and secure with screws to form the back of the shelf.

Step 3

Attach the shelves to the doors

Mark the locations of the shelves (Project Diagram, Drawing 6) on the assembled doors. Drill pilot holes and secure the shelves to the doors with glue, secure with finish washers and screws. Just drive the screws enough to make the joints close, the finish washer will help prevent you from driving the screw through the thin door skin.

Step 4

Apply primer and allow to dry. If necessary, apply a paintable caulk to any gaps between the jig sawn edges of the shelves and the doors to get a clean finished look. Now apply two coats of paint to the finished project.
