 Using masonry bits, drill holes into the bottom of your largest and smallest pots. This is for air intake to stoke the convection currents. Make sure you drip water onto the pot as you drill to keep the blade/bit from getting too hot.

 Using a masonry disk or tile cutting bit on a dremel (or an angle grinder), cut the bottom off your middle sized pot. This will be the lid, as shown here. Again, as with the holes in the bottom, make sure you drip water on the pot as you cut. This will save your blade and reduce particulate matter in the air (dust, etc).
