This is a completely custom design that I put together to fit the needs of someone with a growing shop occupying a small space. With a section of solid top, two flipping stations and lots of storage, this bench allows for a tremendous variety of uses without giving up any more of a footprint than a standard workbench would. 
More than likely you found these plans via my multiple YouTube videos documenting my build process. If by chance you haven’t seen those, make sure you check them out for a very detailed look at how to assemble one yourself. Watch YouTube Videos
