I recently finished the frame for a 2x4 bench/table using those metal connector brackets and screws available in most hardware stores. I was impressed by how close to square everything ended up (although I took pains to pick out the straightest 2x4's I could find.) At any rate, I haven't added a top yet. I was planning on slapping on 3/4 inch flooring grade plywood and call it a day - but then I thought I might like a nicer/smoother surface. This bench will be for miscellaneous garage type stuff, with only occasional woodworking application. I thought an alternative might be 1/2" ply with replaceable hardboard on top, something along those lines. I'm pretty weak on available materials out there, though - any suggestions along these lines? The bench is 24" wide supported by 2x4's around the perimeter. The edge of the top will be flush with the outer edge of the perimeter framing.
Thanks in advance, Al
