Step 5Cut the pieces for the front and back beams
First break down a box so that it can be laid our flat.
The front beam is 20.0 x 5.0 x 1.5 (in) . To form this beam cut approximately 12 rectangular sheets that are 20.0 x 5.0 (in)
The back beam is 20.0 x 23.5 x 2.0 (in). To form this beam cut approximately 16 rectangular sheets that are 20.0 x 23.5 (in)
You will be cutting lots of these beam sheets. It's helpful to find a good straightedge like a yard stick or as you may notice in my photos we used a whole foods catering tray that I pulled out of the trash :)
Also we wanted to avoided having creases in our sheets, so we cut off flaps and stray pieces to leave a nice rectangular sheet of cardboard. Don't recycle those scraps just yet! We will reuse them in later steps!
Tip: When we cut the rectangular pieces we cut the edges so they aligned with the corrugation pattern of the cardboard. When you cut a rectangular piece you will notice that two adjacent sides have a different appearance when viewed from the side. One side reveals the zigzag pattern. The other side, the non-zigzag side, will look more like two sheets of paper with a small gap in between. I would recommend cutting your 20 dimension so that it is the non-zigzag side. This will make the edge that people see show the zigzag patterns. It looks cleaner and perhaps aesthetically looks stronger than the non-zigzag pattern.
