I was going to build a small 2 x 2 ft table but the metal supplier had a 2' x 4' x 1/4 " plate for 25 dollars so I decided it would be a bettter size and cheaper than if they cut it. I used an old bed frame for legs welded directly to the bottom of the diamonds on the bottom side. The shelf braces are the bed frame cross bar ends. To keep it from bowing in the middle I used 2 three foot pieces of scrap 3/4" black iron pipe to keep it straight. The wheels were from Harbor Freight 2 swivel locking and 2 straight.
