I Can Do That: Dimensional Lumber Bench

Planning a logical sequence for assembling the parts is important. I attached the front and bottom together and glued and nailed them to the ends as a single unit.

Planning a logical sequence for assembling the parts is important. I attached the front and bottom together and glued and nailed them to the ends as a single unit.

The shortest piece of 1 x 12 I could buy was 4′ long. This length allowed me to cut between knots to get a clear piece for the top, seen in the photo at right, and I used the extra to make the 3/4″ x 3/4″ cleats that hold the front and back panels to the ends. I cut the top 1/8″ shorter than the front, back and bottom to provide clearance when it opens and closes.

The two end pieces and the front and back panels were left at their full width; only the top and bottom need to be ripped to finished size. After cutting the ends to length, I marked out the feet at the bottom, made the cuts with the jigsaw, and cleaned up the saw marks with a rasp. I then used my combination square to mark the position of the front and back panels. I placed the panels against my marks as shown in the top photo at right to determine the exact location of the cleats.

To get the last piece positioned exactly where I wanted it, I used a couple clamps to pull the parts into alignment.

When I was sure that my layout marks for the top edges of the front and back panels were 1″ below the top of the ends, I cut the cleats to length, allowing space for the bottom. I then put glue on the cleats and nailed them to the end panels. While the glue was drying, I glued and nailed the bottom to the lower edge of the front panel. I then put this assembly on one end panel, gluing and nailing it to the cleat using 3d finish nails. Before putting the back panel on, I attached the other end as shown in the photo at near right.

I then placed the box face down on my bench and attached the back panel, using a couple clamps to keep the assembly square and lined up with my pencil marks as shown in the photo at far right. After setting the heads of the nails below the surface with a nail set, I was ready to attach the top to the back panel with a piano hinge.

With the top overhanging the back panel, I had room to surface mount the piano hinge. I used an awl to make pilot holes for the screws, and attached the hinge with just a few screws at first to be sure it opened and closed properly. Then I removed the screws and hinge and got the bench ready for paint.

I eased all the edges with my block plane and a rasp, then sanded with #100 grit paper to remove milling marks. If you use a randomorbit sander, stay away from the inside corners where the front and back panels meet the ends. If you get too close, the edge of the sanding disc can dig in. It’s better if you stay an inch or two away with the sander, and work into the corners by hand.

I primed the bottom of the hinged top and the bottom edge of the ends first. When this had dried, I put a screw into the end of each foot to hold the ends off the surface while I painted the rest of the bench. PW
