The swivelling casters look right at home at the bottom of each leg. Since the mounting base on the casters was wider than the bottom of the legs, I let the mounting bases protrude from the sides of the legs and used copper tubing to form a hoop that sits on top of the protruding bases. As I type this article, the copper tubing along the front is functioning as a footrest. Cool, huh? I'm typing this in my underwear, by the way. Seriously. I'd post a pic but the fan mail from all of the admiring girls would overwhelm my ISP's mailserver. Again.
