We've designed these wooden box shelves for heavyweight storage and incredibly easy construction. Use them for hats and gloves, books, games and toys, or even laundry supplies. Custom-size them for whatever space you have available and for whatever it is that needs a home.
You'll be able to build one large box from a sheet of plywood and have a bit left over for another box. Any veneered 1/2-in. plywood will work, but we suggest birch because the grain doesn't show through paint. Buy a quart of woodworker's glue, and 3/4-in. and 1-in. brads for your nail gun. If you don't have a nailer, you can hand-nail, but it will be a bit of a struggle. You'll also need fast-drying wood filler. Buy a quart of B-I-N or KILZ primer and a quart of latex enamel paint in the color of your choice. If you choose a gloss finish, be aware that if you don't pay attention to filling and sanding, every single imperfection will proudly display itself. Also pick up some mini rollers (Photo 6) for applying the finishes. And finally, a flush-trim router bit will speed up the final trimming (Photo 4). That way you can cut the outer panels a little long and achieve perfectly flush ends without the hassle of precise cutting.
It's easiest to rip the parts on a table saw, but you can use a circular saw and a ripping guide. If that's your plan, use a crosscutting guide (Photo 1) when you cut the lengths. Use fine-tooth crosscutting blades for both types of saws. After deciding on the size of your box, you'll need to rip two different widths for the box panels. Rip the four inner panels 1/2 in. narrower than the final box depths, and rip the four outer panels to match the final depth. Be sure to rip enough material to get all of the parts made. If you like adjustable shelves, drill the peg holes before assembly. Measure the inner box after assembly to get the dimensions for the back panel. Cut the back 1/8 in. overlong in both directions and rout off the excess as we show in Photo 4.
Assemble the outer box with glue and nails. As you glue and nail on the back, bend out any bows in the sides (Photo 2).
Cut the top and bottom outer panels to length, 1/8 in. longer than the box. Apply a bead of glue about 1/4 in. in from the edges and a second bead in a zigzag pattern in the middle (Photo 3). Align the panels flush with the front and with equal overhangs at the ends.
Nail the parts together with 3/4-in. nails. Be careful. It's tough to fix the damage from nails that miss the mark. If you have clamps, use them to squeeze closed any gaps. A tight joint will reduce the amount of sanding and filling you have to do later. For a perfect edge, shave the overhangs with a flush-trim router bit (Photo 4). As before, cut the side panels 1/8 in. longer than the box sides, and then apply and trim them as you did with the top and the bottom.
Sand the exposed plywood edges until they're smooth, first with 80-grit paper and then 120-grit. Then work wood filler into all of the edge grain, nail holes and dents (Photo 5). After the filler sets, sand everything flat with 120-grit paper.
Brush primer into the inside corners and then roll primer onto the rest of the box (Photo 6). After it dries, voids that didn't get filled will be very apparent. So fill anything you missed, and then sand and prime those spots again. Brush and roll on two coats of paint, lightly sanding between the coats with 220-grit paper.
It's imperative that you screw these boxes to at least two wall studs; no wall anchors of any kind will pass muster. Use at least two 3-in. deck screws near the top and two more at the bottom into separate studs. If more studs are available, use those, too. In Photos 7 and 8, we show you an easy way to position and drill pilot holes so the screws will hit the studs when you mount the boxes.
