Unfortunately, having a hard time getting my hands on a good clean tank. Might be doing a rebuild on a conventional offset first if i cant find one. Thats why I was interested in this style. It would be easy to convert it since it needs a new firebox . Got it for free
Have you ever tried recessing the firebox partially under the CC and cutting the hole in the top of the firebox so the air goes straight up into the CC? I always wondered if that would work better on those jambo style cookers
Next virgin 250 gallon tank I can get will be turning into something like this. I want to collect the heat lost off the top of the firebox , helping it be more efficient . Also need it to be easier to clean out that a reverse flow thats why the pipe instead of plate.
If you raise the exhaust stack up to fix the first concern, now your dumping all your heat, making it very inefficient due to no mass absorbing the heat before it can exit.
Same if you try to divert the air flow up and over the meat to keep from browning or sooting it up.
Just my concerns with...
Ive always wanted to do a build as you describe, but always had two concerns;
With such a low exhaust pipe, the stail air and moisture build up on the top inside of the CC might give the food too strong a flavor for my taste.
And with the firebox dumping into the CC so close to the food I...
I think its a good thread. My only argument is the formulas dont give a minimum or maximum diameter and just feel giving a recomended diameter to volume would eliminate confusion assuming length has very little effect ( with in reason)
Im just thinking it mau be easier to just give them a chart that says cc between this and this size should use pipe between this and this size? Maybe less complicated for the average joe.
Inkjunkie, in response to your remark. Please tell me how its any different to just tell you what size pipe you should use rather than using a fancy formula? Its all still based on experience of what usually works and what has not. One may "feel" more scientific to you, but its not.
I dont like these formulas at all. A guy that has a two inch piece of pipe laying around will think he can use it on a 100 gallon tank as long as he makes it long enough, same with a guy with a piece of 10" pipe if he makes it short enough. But neither of those cookers will be worth a darn. A...
I have always believed that the diameter is more important than the length, and only consideration I put into what length to use was how it looked and if it got the smoke above eye level or tent level.
