So I built a heatermeter last year for my crappy sidebox smoker grill. After realizing the heatermeter worked beautiful and my issue was all the heat loss in my crappy smoker i upgraded to the WSM 18 yesterday! This thing is beautiful so i really don't want to cut and drill it to much but I want to pair the heatermeter/roto with it. Looking for some ideas of what others have done. thinking i could run pipe into the 3 small holes on the stock vent and hook the heatermeter up to that sort of like a manifold. not sure if I'll get the desired air flow tho. Thanks guys
