DIY Modern Raised Planter Box // How to Build – Woodworking
With the outer walls of the planter box attached, I could go ahead and get to work on the bottom. The bottom is made up of 2×6 pieces, and first I measured to confirm the length of the pieces I needed.
Over at the miter saw station, I could go ahead and cut the boards to length, making sure to clean up that factory end on the first board.
The bottom pieces are attached to the panels with pocket screws, so I went ahead and drilled three pocket holes into the end of each board. Getting the settings worked out here were a little tricky, but I eventually landed on having the jig set to the 1 ⅜” setting and the depth stop collar on the bit set a little bit deeper than 1 ½”.
To install the bottom boards, I just lined up the bottom edge of the 2×6 with the bottom edge of the panel, clamped it in place, then drove in a few 1 ¼” pocket screws. On this first board, I used these pocket hole clamps, but they actually left dents in the Cedar, so I switched to parallel clamps for the rest of the boards.
With one board installed and my jig settings dialed in, I could drill pocket holes in the rest of the boards. This pressure treated lumber was so wet that it was clogging up the bit, but I got through it, it just made a mess.
Once all of the pocket holes were drilled, I could install the rest of the bottom boards. As you can see, there is a roughly 1 ¼” gap between each of the boards to allow for drainage. You don’t need to go nuts trying to get this measurement precise, since it doesn’t really matter. I just worked my way in from the ends, leaving a small gap and clamping the boards in place while I drove in the screws.
DIY Modern Raised Planter Box // How to Build – Woodworking: I built these simple yet beautiful modern planter boxes using Cedar from the home center and a few pieces of angle iron. I do have detailed plans available for this project here, which include a materials list, cut list, and SketchUp file.
