Since the legs will attach to the base of your DIY dining table (not the tabletop) you’ll need to build the base first, using some wood glue, a power drill, screws:
Begin building the base by first centering the first two legs on the long side using a 3/8-inch spacer underneath.
Once the legs are centred, you can drill two pocket holes at each joint with a brad point.
Next, you’ll want to glue the joints together, then screw in the two pocket holes for added stability.
Finally, repeat the same process for the other side of the table.
To ensure your base is square, apply clamps to clamp your base together. For added stability, use two pocket holes on each joint as well as wood glue.
Once you’ve completed this process, simply screw the small sides to the legs for your table base.
