Robert O'Brien built his shop with dedicated, mobile stations for each machine. These carts not only serve as mobile storage space, holding all the accessories, tools, and hardware for that machine, but they also serve as auxiliary work surfaces and temporary infeed and outfeed tables. The tops of all carts are 3⁄4-in. phenolic plywood, with a non-stick surface that looks and wears like plastic laminate. A layer of 3⁄4-in. MDF below adds mass. In O'Brien's shop, he has one cart for hand tools and hardware, one for sanding and sharpening, and one each for the tablesaw, dovetail jig, drill press, chopsaw, and router table.
