Step 3: Cut the deck
The deck should be 24 inches wide, and approximately 26 inches long. So cut this out of your plywood sheet using your table saw or circular saw.
The next issue to overcome is the curve of the deck. Honestly, I figured that 3/8" plywood would easily bend to the curve on its own. I was wrong. However, before I started, my wife advised me that I should score the back of the deck to allow it to flex. Yeah, she was right.
So here's how to do it. Set your table saw, or circular saw to a depth of 1/8" and cut lengthwise channels approximately 1" apart on the back of the deck.
