Planter Box - Free Woodworking Plans

Now that most of the large trim has been attached to the planter box assembly, we'll cover the exposed plywood edges of the corners with outside corner trim.

Measure the distance on the box between the top and bottom trim, and cut one piece (with 90-degree end cuts) on your compound miter saw to this length. Align the piece to cover the exposed plywood edge of the corner that you measured and tack the piece in place with finish nails.

Continue around the four sides, trimming each corner in the same manner.

The last part of this step is to sand the entire project, although the plywood shouldn't need much sanding. Fill any nail holes or blemishes with wood filler and sand the filler flush while sanding the entire project. Focus your sanding on the trim boards, making sure that any rough edges or faces are addressed, as we'll begin finishing in the next step.
