I made this yesterday and followed this guy's video using a 12" and 16" pot. I bought a drill bit/easyout for $6 to drill the smaller holes in stainless. I'll build another one using 16" and 20" pots. The Mainstays pots from Walmart now have glass tops so you'll have to make the skirt for the inside pot out of something else. I used a cookie sheet for mine. I sat mine up on a couple of bricks due to my wife's rug. This was for her so she can keep her legs and feet warm sitting outside drinking coffee and smoking her cigarettes.
It worked great and had little to no smoke after it got going. The fire would wick through the top holes as well.
