Notes

  • Use a speed square to mark a triangle on both boards. The corner will be 90 degrees.
  • Use a miter saw to cut 45-degree angles on boards. The angle carries through two (2) pieces of wood in our case to make appx. a 20″ wide shelf. Depending on the thickness and the width of the wood the number of cuts will vary.
  • If possible, you would want to attach flanges to studs and not have to use drywall anchors.
  • You could also glue the boards together first to make the cutting triangular piece easier.
