The first step in construction was to make the sloped panels, since I'm making three sections, I cut 3, 5 inch x 24 inch pieces of plywood and traced out the dimensions of the slope which is 4 inches flat in from each end and a diagonal line connecting the two points over the remaining linear 16 inches (4+4+16=24). The three panels were then taped together and I ran them through my band saw.
I then cut the rest of the side pieces out. Here's the full cut list:
2 x Slope pieces
1 x 4" x 24" 1/2 inch plywood
1 x 1" by 24" 1/2 inch plywood
1x 23.5 square piece of 1/4 inch MDF
Corner section (there will be two of these)
2 x Slope piece
2 x 1" x 24" 1/2 inch plywood
1 x 23.5" square 1/4 inch MDF
rabbet cut in them that will hold the MDF bottom panel.
I used a router to cut the rabbets.
I'm only using glue to hold the thing together but with the rabbet joint there is more than enough holding power. How do I know? Because a fully assembled panel fell off my workbench and suffered no damage. I, ummm, meant to do that by the way.....
The little cube you see in the bottom right panel are some 1/2 inch pieces I cut to reinforce the joints. I ended up only using a few of them as the panels were strong enough.
