Free plans to build a truss style coffee table from ana-white.com
3 - 2x6 @ 8 feet long
3 - 2x3 @ 8 feet long
For attaching, you can use countersunk screws (3" wood screws) or 2 1/2" PH screws and glue.
4 - 2x3 @ 16 3/4" (legs - both ends cut at 10 degrees off square BEVEL long point to short point, ends ARE parallel)
4 - 2x3 @ 19" (end stretchers)
1 - 2x3 @ 37 3/4" (bottom stretcher - both ends cut at 10 degrees off square ANGLE long point to long point ends are NOT parallel)
1 - 2x3 @ 33 3/4" (top stretcher - both ends cut at 10 degrees off square ANGLE long point to long point ends are NOT parallel)
2 - 2x3 @ 20" (truss detail - cut down to make up truss parts - if you saw cuts 55 degree angles, you can also cut these with ends parallel at 55 degrees off square, long point to short point, 15" long)
5 - 2x6 @ 48" (tabletop)
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!
First, build your two leg ends. They will be identical. You can use 1 1/2" PHs on each end of the aprons and 2 1/2" screws to attach, or you can attach from outsides with screws and glue. If you choose to countersink, first drill a hole the size of your screw head 1 1/2" into the leg. Then attach your screw, countersinking the head into the leg 1 1/2".
NOTE: If you plan to attach top with pocket holes (see step 5) then drill 1 1/2" PHs facing upward on insides of top aprons.
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.
