  1. Measure the length and width of the existing tabletop and cut the sheet of plywood to that measurement.
  2. Take the overall length of the existing tabletop and divide that number in half. Cut two sections from the sheet of plywood at this measurement to create your new table extensions.

Tip: You can have a hardware store cut the wood for you if you don’t have access to a saw.

  1. Cut four 2x4 pieces of pinewood to half the length of your tabletop.
  2. Flip the table over so you can work on the underside.
  3. Measure 4 inches in from one leg, along the end of the table. Make a mark. Repeat for all four legs.
  4. Place one of the closed bar brackets on the table so the screw holes rest flat and the bracket is flush with the edge.
  5. With the brackets positioned in place, trace the drill holes with a pencil. Use the cordless drill, and drill four shallow pilot holes for the 3/8” wood crews. (Be careful not to drill through the table.)
  6. With the bracket in place, drive four screws into the wood on your marks, securing the bracket to the underside of the table.
  7. Slip one of the 2x4 wood pieces through the bracket. If it is too tight, loosen the screws until the 2x4 slides easily. Attach another bracket over the 2x4, 4 inches toward the middle of the table.
  8. Repeat steps 6-9 with 2x4s and brackets on all four corners where you previously marked.
  9. Cut two lengths of the piano hinge to the width of the table using a hacksaw.
  10. Attach one side of the piano hinge to the wide edge of the new plywood extension using the cordless drill and screws. Line up the other side of the piano hinge with the existing tabletop edge, and screw the hinge in place so that the hinge closes downwards.
  11. Wear a dust mask, and sand the existing finish as well as the new plywood extensions with 150-grit sandpaper until smooth.
  12. Wipe the dust off with a damp rag.
  13. Prime the table, and let the primer dry.
  14. Paint the table a semi-gloss color of your choice. Let the paint dry.
