A work piece support assembly can be assembled in either an operating configuration or in a flattened coplanar configuration for storage. The support assembly includes a pair of leg assemblies, one each for the proximal and distal end portions of an elongated rail support member. Each end of the rail support member has a portion having two leg socket assemblies. Each socket assembly has a first and second socket with respective first and second centerlines that may be non parallel and intersect at a predetermined point. Each leg assembly has a stem assembly comprised of a first and second stem portion, which are both pivotally coupled to the rail support member through the first and second sockets of each socket assembly. In its operational configuration, the first and second leg of each leg assembly is transverse to the rail support member. In the flattened storage configuration, the leg assemblies counter rotate resulting in each leg assembly being coplanar to the rail support member.
