Looking to create a sturdy, long-lasting picnic table? This detailed guide is based on the woodworking project by CaptainBerz.This picnic table will not only serve your family for years but also withstand various weather conditions.
Materials and Tools Needed
- 5 pieces of 2x10x8 lumber
- 4 pieces of 2×6 lumber
- 2 pieces of pressure-treated 2×8 lumber (for legs)
- 2 pieces of 2×4 lumber
- 4-inch screws
- 2.5-inch screws
- 3.5-inch stainless carriage bolts
- Danish oil (light walnut)
- Oil-based spar urethane (satin finish)
- Liquid nail adhesive
- Sandpaper (150 and 220 grit)
- Miter saw
- Drill
- Clamps
- Level
Step 1: Prepare the Tabletop
Start by laying out the tabletop. Place your five 2×10 boards edge-to-edge, ensuring the best-looking surfaces are facing down. Use nails as spacers between the boards to maintain even gaps.
Step 2: Cut and Attach Cleats
Next, cut three 2×4 cleats to 32 inches long. Miter-cut both ends at 45 degrees and sand the edges smooth. Apply liquid nail adhesive to the bottom of the tabletop where the cleats will go. Secure the cleats with 2.5-inch decking screws.
Step 3: Cut the Legs
Using the pressure-treated 2×8 lumber, cut the legs at a 28-degree angle. The height of the legs should be around 32.25 inches to accommodate a comfortable seating height. Make sure the edges that will touch the table are not rounded.
Step 4: Assemble the A-Frame Legs
Cut and fasten a 2×8 cross brace between each pair of legs to form two A-frame assemblies. Position the legs so that they are aligned with the cleats on the tabletop. Use clamps to hold everything in place while you drill and secure with screws.
Step 5: Attach the Legs to the Table
Once the A-frame assemblies are complete, attach them to the underside of the tabletop using 4-inch screws. Mark the positions carefully to ensure they are level. This is crucial for stability.
Step 6: Prepare the Benches
For the benches, cut two 2×6 boards to 96 inches long. You will also need additional 2×4 pieces for support. Sand the edges to ensure they are smooth, especially where people will sit. Pre-drill holes for screws to avoid splitting the wood.
Step 7: Assemble the Benches
Attach the bench boards using 2.5-inch decking screws. Ensure the benches are securely fastened to the cross braces. This will provide additional support and stability.
Step 8: Sand and Finish
Sand the entire picnic table and benches with 150 and then 220 grit sandpaper. Focus on the tabletop and edges to ensure everything is smooth to the touch. After sanding, apply a pre-stain conditioner followed by Danish oil for coloring. Finish with several coats of spar urethane for weather protection.
Step 9: Final Assembly
Once the stain and finish have dried, flip the table over and check for any rough spots that might need additional sanding. Ensure everything is secure before using it.
Congratulations! You’ve built a bomb-proof picnic table that can withstand family gatherings and outdoor dining for years to come.
