To make assembly of the water feature float along, we’ve provided two animations that will help you visualize the steps. Watch the videos for some soothing assembly instructions.
From a 1 x 12, cut the sides (A) and top (B) to length (Project Diagram). From 1 x 4 boards, cut the bottoms (C), cross rails (F), and side rails (G) to length. From a 1 x 8, cut the wave boards (D) and front (E) to length.
Water Feature Frame:
Assemble the outer frame--the sides, top, and bottoms--using glue and 2-inch deck screws (Drawing 1, Project Diagram).
Print the wave board patterns and trim them to size. Attach the four parts of the pattern to one of the wave boards using spray adhesive (Drawing 2 & Wave Board Patterns, Project Diagram). Use a jigsaw to cut the wave boards into front and back halves. Trace the profile from the first cut wave board onto the remaining board and cut to shape.
When using a spray adhesive for mounting patterns to a board, use a light coat; the pattern should come off easily after you cut the part to shape. If the paper pattern sticks and is difficult to remove, wipe the pattern with mineral spirits and peel the paper off. (Wear rubber gloves when handling mineral spirits.)
Lay the frame assembly on its back and secure the back halves of the wave boards into position using glue and 1-1/4-inch screws--use 1-1/2-inch-thick scrap material to position the back edge of the wave boards off your work surface.
Set the aluminum screen into position. Start by attaching the bottom edge flush with the bottoms of the wave boards using #6 x 1/2-inch screws. With the help of a friend, gently press the aluminum over the wave boards to form the curve. Use screws to secure the aluminum to the wave boards every 8 inches along the curve.
Place the front halves of the wave boards in position and secure to the sides with screws and glue (Photo 3).
Install the remaining internal parts: the front (E), side rails (G), and cross rails (F) (Drawing 2 & Wave Board Patterns, Project Diagram) and driving screws through the sides into the parts.
Apply masking tape to the screen adjacent to the wood and apply an exterior stain with a brush. When the finish has cured, remove the tape.
Apply silicone sealant to any drain holes in the bottom of the window box and set aside to cure.
Water Feature Plumbing:
Cut two pieces of 1/2-inch CPVC pipe to 21-1/4-inch and 4-1/2-inch in length. For the longer section, drill 1/8-inch drain holes 2 inches apart along the length, then clear the debris from the pipe.
Apply CPVC primer and cement to one end of the 21-1/4-inch pipe and install the 1/2-inch CPVC cap; install a 1/2-inch elbow on the other end (Drawing 4, Project Diagram). Twist the pipe so the holes are slightly angled toward the back of the water feature. Insert the 4-1/2-inch long pipe into the elbow and then add a 1/2-inch wing elbow to the end of the pipe. Use primer and cement at each connection.
When applying primer and cement to plastic pipe, use the swab applicator that comes with the can, it's attached to the inside of the lid. Apply the primer to the inside of the fitting and the outside of the pipe. You need to prime only about 3/4-inch of the end of the pipe. Then close the primer can, open the adhesive container, and swab the cement onto the outside of the pipe and inside the elbow. Immediately push the pipe all the way into the fitting, hold for 15 seconds, and then wipe off the excess glue with a paper towel. Repeat for the remaining fittings.
With the top pipe assembly complete, turn the water feature assembly upside down on your workbench and fit the assembly into the box; secure the pipe assembly into the case by driving stainless-steel screws through the wing elbow into the top (B).
Cut the 1/2-inch aquatic hose to 37 inches in length, and then attach it to the 1/2-inch CPVC wing elbow and pump using glue and primer. Run the hose behind the wave board and secure to the side (A) using tubing straps and screws.
Turn the water feature upright, attach the other end of the aquatic hose to the pump, and place the water pump in the window box.
Wash the marble stones to remove any debris that could clog the pump, and run the cord out of the planter. Fill the planter with the stones, slip the window box into the water feature assembly, and set outside. Fill the window box with water and plug in the pump. Now relax to the sounds of your newest backyard creation!
