wheeled carts for overwinter containers
I plan to spend part of Thanksgiving building some sturdy wheeled platforms for my mother and father in law. They have a great collection of plants that spend the warm months on their big deck, but in winter they keep them in the garage to protect them from frost. On warmer days (40s or 50s are common in NC winters, esp. lately) they open the garage and drag each huge plant out into the sunshine. That takes time, and I am concerned that back injuries are inevitable. So 2 or 3 wheeled platforms would allow them to easily push the plants in and out of the garage.
I have solid carpentry skills and tools. I am going to use decking techniques, basically. I'd like some thoughts on size (4x4', 3x5', etc), materials (pressure treated, plywood, plastic composite), and any features something like this should have. Thanks!
Also, is there another forum that this should go in? I'll crosspost in tools.
