10 - 1x3 Boards, 8 feet long
6 - 1x3 @ 18" (Porthole sides)
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!
The most difficult part of this project is going to be getting those boards cut just right - namely this circle. Cut your six boards straight, as shown above, 18" long. Lay out with 1/4" spacing between the boards and draw a 5" circle on the boards. Then cut the circle parts out of each board with a jigsaw. You will need to do this on both sides.
Now space the remaining side boards out, 1/4" appart as shown above. Notch the bottom out 1/2" up as shown above with a jigsaw so that the table will sit flat, despite uneven surfaces. You will need to do this on both sides.
A picnic table that looks like a pirate ship! Add an umbrella and every day dining is literally a breeze.
To the top board, add the top cleat as shown above.
Now it's time to assemble the sides. Start at the top and work your way down, keeping a 1/4" gap between all of the boards as shown above.
Seat cleats. Add the seat cleats as shown above. If you want to be extra fancy, you can cut the seat cleats at a 15 degree angle. Glue and screws would do the trick.
Now we need something to keep the ends in place. Add the angled cleats as shown above, and the cleats around the portholes. Again, 1 1/4" fasteners and glue.
If you have a Kreg Jig™, consider building the top and seats first, and the adding to the top. But if you don't, here's how you can still get those breadboard ends. Screw (predrilled holes) and glue the breadboard ends to the top as shown above. The top will overhang 1/2" on both ends. Seats will sit flush.
Now join the two sides together using the base support boards as shown above. Screw to the cleats and also to the sides.
And finally, attach all of the top boards as shown above. Carefully predrill holes and use 2" screws and glue. Adjust for square.
