The work table surface is formed by a pair of horizontally spaced apart horizontally disposed members secured to the outer longitudinal vertical surfaces of the leg members which provides space therebetween sufficient to allow work tools to operate therebetween on work pieces supported on the top support surfaces of the horizontal members. A horizontally disposed shelf is pivotally connected to the table in one position and in a second position extends over the top of the horizontal members to provide a solid top work surface.
