I recently got a new tank, which is around 35" in diameter and the straight part is 51" long. I'm going to cut the FB end off and weld a new end plate, since I've found out that it's much easier to work around that flat end. Naturally I'm going to keep the other end to allow for good airflow.
I have a question for the RF gurus, Dave, Rib, ... How much I should adjust from the Feldon's calculations since this is a short and fat tank?
For my previous build which was "standard shaped" I adjusted as suggested, 150% for area under the RF plate and for the gap to CC.
I have not adjusted for the FB to CC opening, should that be also done? My cooking style is mostly hot and fast at around 325F if that affects "tuning".
I have a lot of space, so I could theoretically still use 1.5 what Feldon says, but I'm going to run into ground clearance problems with the FB.
What is the minimum height for firebox that would still work okay? I think I'm going to make my FB as wide as the tank and pretty long, but it could only be maybe 15-18" in height. For the vents I'm going to make one lower main vent and one upper vent for better heat transfer to CC.
Any other advice for short and fast tank? Would you make double doors on both sides even if the racks were slide out?
