Getting the adjustments of the skirt, the right spacing between the stove and the pot and the skirt is very important and it may take a couple of tries. (The wok supports have round holes, you may tinker with it and discover whether you need them). You may also need some form of additional support under your larger pots, which is another thing to consider if you are building something. Once you know what you need, use that for a while, or have a local metalworker build it in steel (no galvanized). Stainless is prettier, more durable and more expensive.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:windowtext'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:windowtext'>OR you may decide that those wok rings are cheap after all.
