Another visual data point, assuming this GIC link comes through in
usable form: <http://galootcentral.com/index.php?option=com_copperminev-

        The top is a chunk of ~3x12 pine beam that I found in my barn
        some years back. The slot in the middle of the top can be used
        as a carrying handle, but is large enough to accomodate the head
        of a Jorgensen-style bar clamp for cinching work down as needed.
        Legs are 2x6 scraps set into mortises that leave the top
        unbroken, secured by two long screws. Braces are one-by scraps.
