Made a mobile welding table for home use a couple months back. It measures 30"w x 60"d x 36"h. Probably weighs about 500lbs plus 3-400lbs of scrap metal in the base. Sits on 6" casters w/brakes rated at 900lbs from grainger for $25/each. Made with w-beams, angle iron and c-channel laying around our shop. We also have a 9' x 12' x 3/4" piece of flat plate we removed from a freight elevator. I'm gonna see how i like the w-beams for clamping first before cut the plate for the table top. The w-beams flanges are nearly 3/8" thick, more then stout enough for anything I'll be making at home. The legs, 3" angle iron and base, 5" angle iron are 5/16" thick. I recently came across some 2 1/2 x 1/4" thick box tubing so I decided to make mounts for a vise, bench grinder, etc - tow hitch style.
