Preparation
5- 1x6. 8ft.
1 - 1/4 inch piece of plywood. 8ft.
1 - 4x4 8ft for legs if raising
1 - 2x4 8ft for base support
Cut to your own specs.

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!
Instructions
Step 1
Cut your wood to desired lengths making sure to account for an inch on each side to allow for ends to fit flush. Also cut 2x4 to fit on bottum for added base support, unless not raising.
Step 2
Drill all pilot holes evenly spaced on edge of wood that will attach to bottum plywood base, and at ends of 1x6's to insure stability.
Step 3
Start by conecting side pieces to base followed by end pieces and then base support. After all are secure then connect legs if raising.
Step 4
Sand and add finish if you desire.
It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.
