Elegant Bench design.
I see this as an HO railroad modeler's "Basic Module" as described in many model railroad associations rules/specifiations. For this, the bench top would need to become a full 30" wide though, and there would need to be adjustment in deck height as well - usually to 40". Also this deck height must be adjustable by using height adjustment screws with a travel of around 3".
My second thought, and probably more lucrative/marketable, is to use the bench to develop a four (or maybe six?) module grouping for a work surface that would create a 51" x 72" work surface for wood working. I would see one bench module as the housing for a tail vise, one for a router table, one for tool storage, one for power distribution, one for dust collection, etc.
So I think that if I model this table, I would increase the height of the deck some, add vertical holes to accept leveling screws in the leg bottoms (that could double as caster mounts for those that insist) and leave the "burning man" stretcher/leg system elegantly supporting the modules of the project.
I almost always think of the final use of something like this as the "second use" of something else. In other words I will be thinking "packaging" of some relevant or related materials as the initial use of the bench...
