Thanks DCman i appreciate your feed back. One moor question for you when you run 2-1.5" intakes how do you set your dampers on the intakes to hank around 225 i'm not planing to run it hot just low and slow so i was just curious thanks. ya that is what happens when your curious i know. LOL
Depends on wind and every cooker is different...but typically it's one intake closed and one cracked about a quarter to halfway open… Is usually pretty good
If you can't fix it by sheer force or cursing......then it can't be fixed.....
Ok Thanks DC. So the second intake is for coming up to temp faster/higher temp cooking i also have a 3" gate valve that should give the air of the 2- 1.5" valves/dampers or more. The way i understand it is that for example a 2"pipe will flow 4 times the volume as a 1" pipe but im not a expert in hydrodynamics. Also i do not know if that holds true only under your fluid being under pressure[ air behaves as a fluid ] or if it flows less when it is under a draft. Im trying to build this smoker with as much matiral as i all ready have so i have something to use wile i build my next bigger smoker. My Dad wanted my First RF that i built and i think im having bbq smoker withdraw right now. LOL
i have two 1.5 inlets on my drum, and when starting i have them both open, when i get near where i want, i close one, and the other is open 1/4 of the way, settles in at 250 and stays there, but like DC has said, each drum is different, and as RC said, you can use all the air you want coming up to temp. You better be able to shut them down as well
