This step by step diy project is about octagonal picnic table plans plans. I have designed this octagon picnic table with an easy access to the seats so you can finally create that unique place for hanging out with the friends and family in your yard. This project can be completed in one weekend with common tools and materials you can find at any DIY store. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build an octagon picnic table
The first step of the project is to build the frame for the tabletop. Mark the cut lines on the 2×4 beams and then get the job done with a saw. Make 45 degree cuts to the beams, as shown in the diagram. Smooth the edges with 120-220 grit sandpaper.
Make 45 degree cuts to the orange supports, as shown in the plans. Use a miter saw to make the angle cuts accurately.
Fit the supports on a level surface and lock them together as shown in the diagram. First, drill pocket holes at both ends of the blue supports and then secure them to the center of the yellow beam using 2 1/2″ screws. Next, fit the orange supports, drill pilot holes and insert 2 1/2″ screws to lock them into place tightly.
Next step of the project is to cut the slats for the tabletop. Make 22.5 degree cuts to both ends of the 2×4 slats, following the pattern in the diagram. Drill pocket holes at both ends of the slats, so you can interlock them together tightly. Add glue to the joints and align the edges flush.
Build the central slat for the tabletop from 2×8 lumber. Make the cuts to the slat using the information from the diagram. Smooth the edges with sandpaper.
After assembling the tabletop with 2 1/2″ screws, you need to center the supports into place, as shown in the diagram. Next, drill pilot holes through the sides of the supports and insert 2 1/2″ screws into the tabletop slats.
Build the legs for the octagonal picnic table from 2×4 lumber, by making 30 degrees cuts to both ends. Smooth the edges with sandpaper.
Attach the legs to the frame of the tabletop, 4″ away from the end of the supports. Clamp the legs to the supports, drill pilot holes through both the legs and the supports and insert 3 1/2″ carriage bolts. Insert 2 bolts for each joint.
The next step of the octagon picnic table is to build the frame for the seats. Cut the 2×4 beams as shown in the diagram and make 45 degree cuts to the ends. Drill pocket holes to the straight end of the blue and violet components and secure them to the yellow beams with 2 1/2″ screws. Align the edges flush and make sure the corners are square.
Fit the seat supports to the picnic table, as shown in the diagram. Clamp the supports to the legs, drill pilot holes through both the beams and the legs and insert 5″ carriage bolts. Insert 2 bolts for each joint for a professional result.
Next, you need to build the seats for the picnic table. Start with the 2×8 base by making decorative cuts to the two corners.
Use 2×4 lumber for the seat slats. Make 22.5 degree cuts to one end of the slats and then lay them on a level surface.
Secure the slats together tightly with 1×2 supports and 1 5/8″ screws. Drill pilot holes before inserting the screws to prevent the wood from splitting.
Use 2×6 lumber for the diagonal braces for the seats. Use a miter saw to make 19 degree bevel cuts to the braces. Drill pocket holes at both ends.
The next step is to assemble the seats by locking all these components together. Use 2 1/2″ screws to secure the braces to the bottom slat and to the seat slats.
Notice how you should fit the braces into place.
Smooth the edges or use a router to round-over the exposed edges.
Fit the seats to the picnic table, as show in the diagram. Center the base of the seats to the legs. Drill pilot holes through the legs and insert 2 1/2″ screws into the base of the slats. Afterwards, drill pilot holes through the seat slats and insert 2 1/2″ screws into the supports.
Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and let them harden for a few hours. Smooth the surface with 120-220 grit sandpaper and round the exposed edges with a router. Apply a few coats of paint or stain to protect the lumber from the elements and to enhance the look of the octagon picnic table.
