Cut Plywood for the Bottle Supports
Knock out the bottom of the planter and remove any nails. Cut two pieces of plywood to the inside dimensions of the planter. Cut 1 inch off the top of the rear support so that it can be tipped into place, as shown in Step 6. On the front support, mark the center of the first bottle hole by drawing lines from corner to corner to form an X.
Mark the Centers of the Bottle Holes
On all four legs of the X, mark a point that’s 2¾ inches in from each edge of the support. These will be the center points of the bottle holes. Check to ensure that the marks form a square, with enough space to cut all five bottle holes.
Cut the Bottle Holes
Clamp both supports, with the bottoms and sides flush and the hole markings facing up, to a worktable on top of a piece of scrap wood. Center the hole saw over the middle of the X, and drill through both supports. Repeat for the remaining holes.
Paint the Interior Surfaces
To unify the materials and protect your wine collection from exposure to light, paint the interior surfaces of the planter and one side of the rear support in a dark color.
Cut the Front Support into Strips
Mark off strips of the desired width and spacing on the front support. (Ours were 2 inches wide.) Use a miter saw to cut along the lines; set aside the pieces you’re not using. Cut spacer blocks from a 1 x 2 to the desired gap between the strips. (Ours were 2 inches apart.)
Install the Front Support Strips
Nail the lowest front support strip to the inside of the lip. Lay spacer blocks on top of it, then nail the next support strip in place above it. Repeat until all strips are installed. Remove the spacer blocks.
Install the Rear Support
Apply wood glue along the perimeter of the unpainted side of the rear support. Tip the piece into the planter and pull it snug against the inside of the lip so that the glue makes contact.
Finish the Wine Rack
Use a damp rag to wipe away any excess glue from Step 7. Stand the planter upright on its back while the glue dries. Conceal the joints with wood filler. Sand the entire assembly, and finish with primer and two coats of satin or semigloss paint.
