First thing I did after studying Keith's site was to come up with the plans. I drew these plans up in Visio. The steel for the frame is 1 1/2" x 1/8" square steel tubing. The steel for the keg seats is 1/2" square solid bar. I bought the steel from my local welding shop. ("The Welding Shop" in North Bend, WA).
My original plan was to have a friend of mine weld it for me. However, at the last minute, he was forced to back out. I had no choice but to weld it myself, so I went out and bought a Mig welder, and started practicing. [Note: My hat is off to anybody who welds for a living. It is a LOT harder than it looks. My "flat" welds came out ok looking (thanks to the angle grinder), but the interior angle welds look like crap. Oh well. This is the main reason I changed my design so that no downwards shear would be held together by one of my welds.]
I decided that I would simplify my plans from what Keith had in two areas:
