I am in the planning stages of building a reverse flow 80 gallon air tank smoker. I have put all the numbers in the Feldon calculator, but I dont understand the half moon diameter. On the numbers I entered its says. 12.77 inches for a half moon. Do i cut a half moon out of 12.77, or do I cut a half moon out of 6.385 circle??? 12.77 seem really huge. Thanks
