Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
And then simply follow instructions to add the leaves to the sides with the hinges shelf supports. Take care to make sure the overall height of the leaf tops are flush with your saw deck.
Some ideas - add 2x2 with a appropriately trimmed yard stick on top as a quick measure fence for your miter saw to the tops of the leaves.
