I built mine using a 24"x36" service cart from Harbour Freight. I cut a hole in it for the fire pot, then lined it with 2" of homemade refractory. The blower is an a giant industrial 4-speed squirrel cage. It had far too much blast, so when my little brother was on leave from Iraq, he built an airgate for it. It works pretty good. I didn't buy the fire pot; I welded it up from 1/4" mild plate from Home Depot. The cart came with a push handle on one end, and I use that as a tool rack for the hammers, tongs, etc. that I'm using at the time. There are a couple of things that I'll do differently on the next one, but overall, it turned out pretty well. It was definitely an educational experience, and its very functional.
