I'm having an offset smoker built, and I'm checking my numbers on the Feldon calculator. The calculator says I need a 45.25 sq. inch opening. My builder thinks this is too small. I have read good reviews on the calculator and think I should go with its number. What are the thoughts of forum members that have experience with builds?
