The finished size of your screens defines the interior horizontal dimensions of the box. If yours differ from my 24" x 19" screens, add or subtract as needed from the following measurements.
Using the fine-toothed plywood blade on your circular saw, cut from the plywood:
- One 24"-wide and 28" high back
- Two 20" x 28" sides
- One 22" x 26" top
- One 27" x 27" door
- One 25" x 27" bottom panel
With the planer blade on the powersaw, from the 1" x 6" stock cut for the base:
- One 27" back board and two 23" sideboards
From the 2" x 6" stock, cut:
For the top and base frame boards, from the square stock, cut:
- Two 19", one 21", one 24", two 22", three 26", and two 28" lengths
For the screen-supports, from the quarter-round molding or more square stock, cut:
- Twelve 18" and six 22" lengths.
Assembling the Folding Box
First, connect the side panels to the back panel with piano hinges. Placing the best side of the plywood down, lay a side panel on each side of the back panel — long dimensions running up and down. Nudge long sides of the two side panels an even 1/8" away from the long sides of the back panel. Place hinges between back and side panels with the flat side of the hinges facing up, the mid-hinge bumps nestling into the space between panels. Use your steel rule to assure that top and bottom edges of the panels are even, so the box will set square. Tap panels as snugly together as you can without pushing the hinges up. Then insert the little wood screws that come with the hinges into 1/16"-wide, 1/4" deep pilot holes, drilled through the precise center of the holes in the hinge and into the plywood (use a centerpunch of sharp nail to center the drill bit). Tighten brass screws by hand, not with the power driver — too much torque can bruise the soft-grooved heads.
To locate the rack rests, scribe eight lines from side to side, across all three panels every 3" from and parallel to the bottom edge. Do not fix rails to the top or the bottom lines. Apply waterproof glue to one flat side of the six 22" lengths of quarter-round molding and center them with their top edges just below the lines on the back panel. Locate the 18" quarter-rounds with one end 1 1/2 " in from the outer edges of each side panel and glue in place even with the rails on the back. As you go, pilot-drill and set 3/4" brass screws through the belly of the quarter-round rails and into the plywood — one screw an inch from each end and one in the middle.
