RF 120 gal propane tank smoker trailer

[jpbsmoke]

Hello everyone I am looking to build a RF 120 gal propane tank smoker trailer. I want to make sure I have my measurements correct before I mess anything up. According to the feldons calculator I came up with this.
Fb 22x22x22=10648cu in. 115.2% size diff from recommended
4" pipe chimney 36.87" tall
Fb air inlet 3"x10" 1 opening
Fb to cc opening 14.73" half moon
I am confused about how to measure to cut my fb opening on the tank. Any help or suggestions would be greatly appreciated. Thanks Jon

Thanks that cleared it up for me I wasn't sure of what to put in for the circle calculator. But I think I have it figured out. I will draw it up and post some pics for some more advice

Can anyone tell me if these calculations are correct? This is if the tank wall is 3/16"
