Hello guys! First time posting on a forum ever. Been reading this forum for a while and finally found/purchased my first 120 gallon tank to start my offset build. I’ll cad/draw it all up and read as much as I can before I ask for recommendations. Any guidance will be appreciated. So far I’m thinking one door, 2 inch 8th inch thick square tubing for the frame, and 6 inch stack diameter with a collector design. I’m apprehensive about whether or not to insulate my firebox due to steel prices and tank door cut location. Are they at 12 and 3 o’clock on 120 gallons 24 inch diameter tanks too or just 30 inch diameter tanks? Thanks for the opportunity to ask you guys these questions.
