Once the floor piece has proven ready, set the floor in place, marking at least one spot so that you can place the floor in again, in the exact same position. Drill pilot holes directly through the plywood and into the bottom of the walls, spacing the holes about four to six inches apart.
Remove the floor. Spread glue on the bottoms of the walls. (cotton swabs or rolled paper can work effectively as spreaders.) Replace the floor, in the correct position so that the pilot holes match, then screw the floor to the walls. As you can see in the photo above, I used a Phillips head attachment on my drill in order to set all the wood screws.
Once the main frame is completed, add 1 x 3 bracers on two sides and on the back of the table. The side braces can be parallel to the ground, but at the least, the back bracer should be set at an angle to improve the wedging table's stability. Again, use both wood screws and glue for the strongest possible joints.
