I wanted to build a small wood storage cart on wheels to safely store small cut sheets of plywood and masonite, and with a second side to contain cut dimensional lumber. I took my design from the Woodworking for Mere Mortals guy, only ours is smaller in both horizontal directions and lacks the shelves in the middle. We have a small garage/workshop, so we figured this would fit better in our space. Here is a link to the inspiration piece: http://www.woodworkingformeremortals.com/2013/01/make-rolling-lumber-cart.html
Well, it took the better part of a week, but much was learned, and our wood storage cart came out great! And we filled it up immediately.
