just wanted to say wow, alot of knowlage here ! im in the design process and checking out alot of the builds here on this site.absolutley awesome! im hoping for input due to lack of math skills and never ever building one , basicllylong time smoker first time caller so to speak. i have a 125 gallon air compressor tank that im starting out with. its going to be a patio style roll around.. ive went on one of the sites for figuring the math and after reading a ton of the builds , cmae to the conclusion that its probably not 100% correct. so with that i want to ask for help with the calculations. any and all helpwould be great. i havent cut anything or welded anything yet and im thinking i need to cut the CC Door out so i can get actuall numbers. unfortuntley i blew out my right knee 3 days ago so getting to the tank and working on it is on hold. so lots of reading and surfing this site is all i can do for now .
