I stood on one of the 'long' ends and bounced up and down on the balls
of my feet. It didn't move. That design is one of the things I like
about it--plenty of room for me to clamp stuff to the edges, and get in
close to it without bumping into the legs. For slow TIG welding, I
could even get a stool right up the edge and sit on it with my legs
under the table. I'm still pretty wretched at TIG welding, so being
able to sit and brace myself without having to hover with my weight over
the work will be a help, I think.
The foot is maybe three feet on a side, also half-inch steel. It's a bit
like the old Mustangs--it's got plenty of 'road-hugging weight' keeping
it steady. :-)

That's sort of what I had in mind. I just need to find two large, true
I-beams and some really big clamps. How much overhang should I leave?
I want more than I think I'll ever need, but I want to support the top
enough not to sag again. The existing supports run diagonally from the
column towards each corner, and they probably stop about two feet from
the corners. I would have thought that would have been enough, and it
makes me want to go almost all the way to the edges...but I never want
to bump into a support with a clamp on the edge.

I'd like to weigh mine. Putting together a shop involves a lot of
creative, third-century B.C.-esque moving techniques. For the TIG
welder, I had to put the engine crane in the bed of truck, lower it onto
the ground, tilt it until I got pipes under it, then roll it over the
pipes until I got it where I wanted it in the garage. This table is
going to be like that.
