I had some extra cedar boards laying around so I figured I'd build a planter box, which is something I've been wanting to make for some time now. I really loved the way it turned out but it was a very complicated process seeing as I didn't have a plan to begin with. But, most of my good ideas come from plans that I haven't fully thought out. Anyways, here's the process!
First, I assembled the base of the planter with plywood. I cut x4 12"x14" inch boards, and used a brad nailer to to assemble the box (although I highly recommend using screws) Then I measured the bottom and cut a piece of plywood that fit perfectly as the base and nailed it in. Then I drilled holes on the bottom for drainage, and spray painted it black. I used Rustoleum Charcoal Chalk Paint.
While waiting for the box to dry I decided I wanted to rip the 8" cedar boards I had into strips measuring 2" then cut each down x12 at 14.5" and x12 at 12". 6 panels for each side.
I used wood glue and a brad nailer to nail the panels onto the box. Nailing the 12" ones down first then the 14.5". This is where I should have done some more planning because the spacing between each panel was such a random measurement at like 7/16th an inch. It was very difficult to space each out so I kind of just eyeballed it, and it worked out fine for me. I did butt joints as well but for a cleaner look I recommend mitre joints.
Once assembled I attached the swivel casters on the bottom four corners and sealed with a couple coats of polyurethane. On the inside be sure to used 2-3 coats because the plywood will not hold water well over time. This planter should be used primarily for indoor use because of the plywood.
All in all this was a process but I'm excited to make more for my home.
