Tried to use saw horses and a sheet of plywood for a workbench but it was not stable. I decided to build (assemble) one using 2X4 Basics hardware ordered from Northern Tools. It was easy to assemble using precut 2X4 from Home Depot. Used standard 4' X 8' plywood for the top and bottom shelf. I added a middle shelf later (5/23/09) for additional shelving space for parts and tools.
