My son loves his big red wooden wagon. It made me remember when I had one, and wished I still had it. But a kid’s wagon is too small for yard work, landscaping and other things I would want one for, so I made my own from scratch. The top is a 2’ by 4’ sheet of ¾” Birch plywood and Poplar 1X4s. The framework is made from 1/8” steel angle and flat stock. The wheels were replacement wheelbarrow wheels bought new. The finished bed has a rosewood oil treatment and I am going to make the red sides soon.
