Good afternoon, Been lerking for a while but finally decided to join and ask a few questions. This will be our first smoker. Husband family had always used a side firebox, but it seemed to use a lot of wood, and we had to move meat around otherwise it would crispy by the fire box. Result they often wrap the meat in foil which seems to defeat the purpose of smoking After doing research on here we've decide to give RF a try. He found a 250 gal propane tank, we've cut the rounded ends off (plan to make fire pits and sell them). CC is 30x70 = 49500 cu in FB is 29x24x24 = 16700 cu in Plan to put the RF plate 10" from the bottom Using the half moon the FB to CC would be 205 sq in These seem to all be in line with the numbers I've found on the forum. here are the questions I have so far. Chimney - does it need to be round or can it be square. Math wise a square would allow the chimney to be shorter since a 3 in sq has more area then a 3 in circle. Doors - do the doors have to open at the top, I've always had an issue with not being quite tall enough to get the door to flip over, or to be able to reach the handle to shut the door. Opening from side would make it easier, but it's a 28ish door. Hinges - is there any advantages to a three piece hinge where one is on the door fits between two on smoker with a pin through it, verse an l shape. I'm sure I'll have more questions but that's all I can think of at the moment.
