Foundation
The foundation is constructed out of 2×4 lumber and decked with 0.75 inch plywood. The only special feature iOS that it is designed to be in two pieces so it can be disassembled to fit through doorways. I was careful to spread out crossmember so they would not interfere with items later during the build.
