Widen a workbench with extension slides

Though my old workbench worked well enough for most ordinary tasks, it just wasn't large enough to accommodate large sheet goods. At least it wasn't until I mounted a salvaged set of 24" table extension slides to each end. The 2×4s screwed on edge, as shown, provide a worksurface with gaps wide enough to cut between without damage. With the extensions in the closed position, I simply lay a sheet of plywood atop the 2x4s to make a solid, gap-free worksurface.
