i have a 120 gal tank I am in the beginning stages of a build with. The tank is 23”x67”. My firebox will be 24” square...which i know is overkill but it is what i had. I made a 250gal 5 years ago using feldons calc and the build turned out great. The calc tells me i need a 19” diameter half moon firebox to cook chamber opening. I am not sure i will have enough of an opening on the CC for that? The tank is only 23” wide at center and if i go 4-5” below center for the plate. If i remember correctly if I do a 16” diameter half moon FIrebox to CC opening that would be 8” radius right? I dont think I will have 8” of room. Could i extend the diameter to cut down on the radius?
Also, i have some 6 3/4” od pipe for chimney. Calc tells me to use roughly 19”. That doesn’t seem like much?
I like chimneys that go straight up from the cooker and not out from the side but with this tank having the “flatter” caps and not the big rounded caps I do not think I will have room to bring the chimney straight off the cooker. Has anybody every come off the cooker st a 45 and then up? And does the 45 aka elbow count towards the length of chimney?
