WHAT IT TAKES
TIME: 4 hours
SKILL LEVEL: Beginner
Looking for a planter box that fits in just about anywhere? Then this sturdy and attractive planter box is what you need.
Its clever design means it can rest securely on a 2x4 or 2x6 deck railing or sit on a patio, porch or deck floor without tipping. Plus, it can be made just about any length you want. If that’s not enough to get you building, it’s easy to make, even for first-time woodworkers. You won’t need a boatload of tools, either. A table saw is a must, but if you don’t have one, perhaps a neighbor or friend can help. Spend a few extra dollars on cedar, redwood or cypress. These woods hold up better to the moisture they’ll face from watering flowers.
Enlarge the end pattern (See Figure B) to exactly 10-7/8 in. Cut two boards to a length of 12 in. and tape or glue the patterns onto the boards. With a jigsaw or band saw, cut each end (A) using the pattern as a guide (Photo 1).
Mark the length of your box on the boards four times, for parts B, C and D, avoiding knots at the ends; cut to length. The planter box shown is 24 in. long.
On a table saw, cut the bottom board (B), slats (C) and railing spacers (D) to width. See the Cutting List.
Cut the railing sides (E), putting a 35-degree bevel along one edge. Be careful here—remember one side is rough and the other smooth. You can have either side facing out, but be sure to cut the angles the proper direction so the finish you prefer faces out.
Stand each end with the top edge down on your workbench and space them apart the length of the bottom board. Center the bottom board on each end and drill pilot holes to avoid splitting the wood. Use waterproof construction adhesive on all joints (Photo 2) before nailing pieces in place.
Nail the railing sides to the bottom as shown in Photo 3. The bevel fits the curve of the end boards nicely.
Working from the top to the bottom (Photo 4), predrill and attach the side slats on both sides of the box.
The spacers should be attached to the inside of each railing side as shown in Photo 5. These spacers strengthen the railing sides and also allow the box to snugly hold onto a 2x4 deck rail.
If you’re applying a stain or sealer to help protect the wood, allow the adhesive to dry 24 hours.
In the meantime, go to the garden center for some potting soil and colorful flowers to brighten up your deck, patio or porch.
