Step-By-Step Instructions

Begin by cutting the four legs for your picnic table. Use two pieces of 90×45mm treated pine timber for each leg. Measure and mark 10-degree angles on each end of every piece to ensure proper splay and stability. Carefully cut along these marks using your circular saw, then smooth out the freshly cut edges with sandpaper for a clean finish.

Next, cut the horizontal support pieces that will connect the legs and hold both the bench seats and the tabletop. The seat supports — where the bench planks will rest — should measure approximately 1500mm in length. The tabletop support should be around 750mm wide. To achieve a polished, comfortable look, round off the exposed corners of each support piece using a jigsaw.

Now it's time to bring the frame together. Attach the table and seat supports to the legs using coach bolts. Start by marking a "V" formation with each pair of legs, then position the supports across them at the correct heights. Pre-drill your bolt holes to prevent the timber from splitting, then secure everything tightly with your socket wrench. Double-check that all connections sit flush and square before moving on.

Measure and cut the planks that will form both the bench seats and the tabletop surface. A standard tabletop width calls for five planks cut to around 1800mm, while the bench seats typically need two planks per side at the same length. Be sure to sand down every piece thoroughly — nobody wants splinters during a cookout. A smooth, rounded edge on each plank makes for a much more comfortable seating and dining experience.

For added structural rigidity, you'll need cross rails and diagonal braces. Cut a long cross rail that spans between the two leg assemblies — this piece ties the entire frame together and prevents wobble. Then cut two smaller angled braces with opposing miters, roughly 450mm each, that will lock into position beneath the tabletop. These braces are the secret to a rock-solid picnic table that can handle years of use.

Secure one end of the cross rail to each seat support using screws. Then position the diagonal braces so they connect from the cross rail up to the tabletop support on either side. Mark your screw placements, pre-drill for precision, and fasten everything down firmly. Give the whole frame a good shake — it should feel solid and stable with minimal flex.

If you'd like the option of shade on hot summer days, now is the perfect time to cut an umbrella hole. Measure the diameter of your umbrella pole and use a hole saw attachment on your drill to cut cleanly through the center plank of the tabletop. A hole in the cross rail beneath will allow the pole to pass through and rest on the ground for extra stability. This small addition makes a huge difference in comfort during peak sun hours.

With the frame fully assembled, go back and drill proper bolt holes at the bottom of each cross rail and leg joint. Make sure each hole is the same diameter as your coach bolts so they fit snugly without any play. Countersink the bolt heads where needed for a clean, flush appearance. This final mechanical step locks the entire structure together with maximum strength.

The final step is all about protection and aesthetics. Apply a quality exterior stain or paint to shield the timber from rain, UV rays, and general wear. A timber stain will highlight the natural wood grain for a classic, rustic look, while paint offers endless color options. Apply at least two coats for lasting durability, allowing each layer to dry completely. Once finished, step back and admire your handiwork — your brand-new picnic table is ready for its first meal.
