Cut two, 45" x 45" squares from 3/4" thick plywood or MDF
Cut two, 8-1/4" x 42-1/2" face panels and four, 8-1/4" x 41" sides panel from 3/4" thick plywood or MDF. Cut the remaining scrap into 8-1/4" lengths of material and various, random widths.
Cut an entire 2' x 4' x 1/4" plywood or MDF "hobby panel" AND an entire 2' x 4' x 1/2" plywood or MDF "hobby panel" into 8-1/4" lengths, at random widths.
Align the lower box face on the top of the bottom panel. Allow a 1-1/4" set-back from all edges. Secure in place using glue and 1-1/4" screws through pocket holes.
Align the lower sides flush to the ends of the lower face. Allow a 1-1/4" set-back from both sides. Secure in place using glue and 1-1/4" screws through pocket holes.
Align the upper face on the underside of the Top. Allow a 1-1/4" set-back from all edges. Secure in place using glue and 1-1/4" screws through pocket holes.
Connect the upper box sides to upper face and the underside of the top. Allow a 2-1/8" set-back from top edges. Secure in place using glue and 1-1/4" screws through pocket holes, as well as 2-1/2" screws driven from the face. The sides will be set in 13/16" from the ends of the face board.
Laminate (glue together) three, 1 x 3 boards, face-to-face. Once dry, cut into five, 8-1/4" lengths. It is much easier to glue and clamp full-length boards together and allow to dry before cutting into shorter lengths.
Connect leg pairs together with remaining stretchers. Secure in place from the underside using glue and 1-1/4" screws through 3/4" pocket holes
Align the center leg 8" from the open side of the lower box panel. Pre-drill into the top of the leg and secure using two, 3" screws.
