After you’ve built this portable workbench, you’ll wonder how you lived without it. Finished in a day with simple hardware and only two sheets of plywood, here’s a work space that’s huge and accessible from all sides yet folds up and stows away easily. If you don’t have room for a full-size permanent workbench but really need space to spread things out, this portable workbench is perfect for you. It opens to a solid 4 x 7-ft. surface with both wings up, yet closes and rolls into a small 4-ft. x 18-in. spot in a corner of the room, perfect for a garage workbench or woodworking bench in the basement.
