You tube is your friend on this. More videos on stove designs and tutorials than I can count.
Small diameter pots bring their own set of snags to the equation. While a top burner with a stand seems the obvious choice, a side burner is not out of the running.
A small diameter pot just means a small diameter stove. If you can use a scissors and a hole punch, you can make a cat-food style stove out of the bottom 2 inches of a Barbasol trial size shaving cream can found in most any local box-mart. Pre warm it and you don't need a pot stand. Cut deep ridges along the top and you don't even need to prewarm it.
Stability becomes the issue then. Anytime you build up instead of out, you run into support problems. Then the option of incorporating a windscreen as a pot stand/stabilizer starts to look appealing. Which brings up the most important aspect of R & D for your MYOG stove, and that is creating a "system" instead of just building a stove.
Some stoves work awesome with their accompanying windscreens, but switch out one of the components and you might not even get a boil, or worse, the stove could overheat and boil out alcohol and create a real disaster. When first starting out building your own stoves, be sure to excersise caution and only test over a safe area. Tipping over an unstable stove with an ounce of flaming alcohol on to your kitchen floor probably wouldn't end well.
With all that being said, the hunt for the perfect setup can be rewarding, addicting and quite therapeutic as well. It can be surprisingly thought consuming as you work through all the nuances of your "design". Of course any pop can stove and tin foil windscreen will boil water, but optimizing efficiency and streamlining design for packability, durability and reliability are the hooks that keep the "stovies" doing what they do.
Well anyway, have fun and good luck!
