Step-by-Step Instructions

Follow these steps carefully to build your own sturdy and attractive picnic table.

Step 1: Cutting the Lumber

Precise cuts are crucial for a well-built table. Use the cutting list below as a guide. Always double-check your measurements before cutting.

* **Tabletop Boards (2×8):** Cut two boards to 72″ long.
* **Bench Boards (2×8):** Cut two boards to 72″ long.
* **Tabletop Supports (2×6):** Cut three boards to 27″ long.
* **Bench Supports (2×6):** Cut four boards to 14 1/2″ long.
* **Legs (4×4):** Cut four boards to 29″ long. (Adjust this length if you desire a different table height. Standard table height is around 30 inches. The 29″ leg length plus the thickness of the tabletop board will yield approximately 30.5 inches.)

Step 2: Assembling the Tabletop

1. **Position the Boards:** Place the two tabletop boards (2x8x72″) side by side on a flat surface, with the best sides facing down. Ensure they are aligned evenly.
2. **Attach the Supports:** Position the three tabletop supports (2x6x27″) perpendicular to the tabletop boards. One support should be centered (36″) and the other two should be positioned 12″ from each end of the tabletop. This leaves roughly 12 inches of overhang on either end of the tabletop.
3. **Secure the Supports:** Using 3″ exterior wood screws, attach the supports to the tabletop boards. Pre-drill pilot holes to prevent the wood from splitting. Use at least two screws per board, per support.

Step 3: Assembling the Bench Supports

1. **Attach the Bench Supports to Legs:** Take one leg (4x4x29″) and two bench supports (2x6x14 1/2″). Position a bench support so that the top edge is 16 1/2″ from the *bottom* of the leg. This height positions the bench at a comfortable sitting level. The inside face of the 2×6 should be flush with the inside face of the 4×4. Attach the bench support to the leg using 3″ exterior wood screws. Pre-drill pilot holes to prevent splitting. Use at least two screws. Repeat this process to attach the other bench support to the *same* leg, placing it on the *opposite* face, also at 16 1/2″ from the bottom.
2. **Repeat:** Repeat step 1 with the remaining three legs and bench supports. You will now have four leg assemblies.

Step 4: Attaching the Legs to the Tabletop

1. **Position the Leg Assemblies:** Carefully flip the tabletop assembly over so that the tabletop boards are facing up. Position one leg assembly at each corner of the tabletop, ensuring that the tops of the legs are flush with the tabletop surface. The bench supports should be facing *inward*, toward the center of the table.
2. **Secure the Legs:** Attach each leg assembly to the tabletop supports using 3/8″ x 3″ carriage bolts. Drill a hole through the 4×4 leg and through the 2×6 tabletop support. Insert the carriage bolt, add a washer and nut, and tighten securely. Use two carriage bolts per leg, placing them diagonally from each other for maximum stability.
3. **Ensure Squareness**: Double check the squareness of each leg to the table top before fully tightening the carriage bolts. Use a carpenter’s square to ensure the leg is at a 90 degree angle to the top.

Step 5: Attaching the Bench Boards

1. **Position the Bench Boards:** Place one bench board (2x8x72″) on top of the bench supports on one side of the table. Center the board so that it overhangs the supports equally on each end. Aim for an overhang of approximately 3 inches on each end.
2. **Secure the Bench Boards:** Attach the bench board to the bench supports using 3″ exterior wood screws. Pre-drill pilot holes to prevent splitting. Use at least three screws per support.
3. **Repeat:** Repeat steps 1 and 2 for the second bench board on the opposite side of the table.

Step 6: Sanding and Finishing

1. **Sanding:** Use sandpaper to smooth all surfaces of the picnic table. Start with a coarser grit (80-grit) to remove any rough spots or splinters, and then move to a finer grit (120-grit or 220-grit) for a smooth finish. Pay particular attention to the edges and corners.
2. **Cleaning:** Wipe down the entire table with a clean, damp cloth to remove any sanding dust. Allow the table to dry completely.
3. **Staining or Painting (Optional):** If desired, apply an exterior wood stain or paint to the table. Follow the manufacturer’s instructions for application and drying times. Multiple coats may be required for desired color depth.
4. **Sealing (Recommended):** Apply a wood sealer to protect the table from the elements. This will help prevent water damage, rot, and fading. Follow the manufacturer’s instructions for application and drying times. Consider applying multiple coats for enhanced protection.

Tips for Success

* **Choose Quality Lumber:** Opt for pressure-treated lumber that is free of knots and warping.
* **Accurate Measurements:** Double-check all measurements before cutting to ensure accurate assembly.
* **Pre-Drilling:** Always pre-drill pilot holes before driving screws to prevent the wood from splitting.
* **Square Assembly:** Use a carpenter’s square to ensure that all corners are square and that the legs are perpendicular to the tabletop.
* **Secure Fasteners:** Use high-quality exterior wood screws and carriage bolts for a strong and durable connection.
* **Proper Finishing:** Protect the table from the elements by applying a wood sealer or paint.
* **Work in a Well-Ventilated Area:** When staining, painting, or sealing, work in a well-ventilated area to avoid inhaling harmful fumes.
* **Consider Adding a Center Hole for an Umbrella**: If you plan to use an umbrella, drill a hole through the center of the table top *before* assembly. Reinforce the hole with a metal ring to prevent wear.
* **Adjust Dimensions:** Feel free to adjust the dimensions of the picnic table to fit your specific needs and space.

Maintenance

To keep your picnic table looking its best, follow these maintenance tips:

* **Regular Cleaning:** Clean the table regularly with soap and water to remove dirt and debris.
* **Inspect for Damage:** Periodically inspect the table for any signs of damage, such as cracks, splinters, or loose fasteners.
* **Tighten Fasteners:** Tighten any loose screws or bolts to maintain the table’s stability.
* **Reapply Sealer:** Reapply wood sealer every year or two to protect the table from the elements.
* **Winter Storage:** If you live in an area with harsh winters, consider storing the table indoors or covering it with a waterproof tarp to protect it from snow and ice.

Alternative Designs and Customizations

While this guide provides instructions for a classic picnic table, there are many ways to customize the design to suit your personal preferences:

* **A-Frame Picnic Table:** This design features A-shaped legs for a more modern look.
* **Round Picnic Table:** A round table is great for socializing and can accommodate more people.
* **Attached Bench Picnic Table:** The benches are permanently attached to the table for a more integrated design. This version can be more difficult to get in and out of for some people.
* **Folding Picnic Table:** A folding table is ideal for small spaces and easy storage.
* **Kid’s Picnic Table:** Scale down the dimensions to create a picnic table that is perfect for children.
* **Use Different Wood**: While pressure-treated pine is the most common and cost-effective choice, consider using cedar, redwood, or even reclaimed wood for a unique look. These woods are naturally rot-resistant and offer a beautiful aesthetic.
* **Stain or Paint in a Unique Color**: Don’t be afraid to experiment with different colors and finishes to create a picnic table that reflects your personal style. Consider using a two-tone color scheme for added visual interest. You could paint the legs a different color than the tabletop and benches.
