I agree that it seems like it sit's to high. Mayne it'll make sense once it's explained? I do think that the fire box is really big for a chamber that size...especially considering it's insulated. Maybe the explanation of the height of the inlet will explain both?

Well, the firebox should've been about a 24" cube (according to the calculators); this one is 26" cubed. It is a bit bigger than called for, but it won't have a negative impact on performance.
EDIT: the recommendations say the firebox should be 1/3 of the chamber. If you think about it, our chamber is 72" long and 28" in diameter. The 26" cubed box is more or less 1/3. If it's bigger, it's a mundane amount. It's about perfect..basically rounded up. This is a Jambo clone..which is why the bottom of the hole was cut at about the "equator". If you have the chance to look inside a Jambo (some of the Jambo owners may be able to lend a hand here), you'll notice that this hole is above the main level grate (which is about halfway up the chamber). There is a baffle of sort directing the heat. The position of the smokestack will draw the heat back down by the time it reaches the far end of the chamber creating an arch. This arch will be somewhat minimal, which helps to eliminate the hot spots across the chamber. It's "unorthodox" but it seems to work well. The smokestack outlet will basically be flush with the main level grate also (the bottom of this opening will start about 1.5-2" below the main level). The placements of the inlets/outlets are virtually identical to that of the Jambo. From what I have seen, our firebox is actually insulated just a tad bit better, too.

See...thought the explanation would make sense and explain both questions!!! It does seem like a big fire box though. Must be the extra steel to encase the insulation.

Yeah. it's thick steel with a 2" gap. That's about 2.5" deep from the inside of the inner box.
Here are a few more updates: The first three are shots of the table. Constructed the frame. Added it to chamber. Placed stainless top on frame. We'll either remove it before painting or wrap it. On the last pic, you can see the stainless flanges on the inside of the chamber. This is a quick shot of the smokestack hole. 6x6. The next two are shots of the grease trap/valve. We have this coming down through the bottom of the trailer.. keeping it out of site. This last one is a shot of the whole rig..Man...it's starting to take shape more and more.. I'm getting excited. We'll probably be cooking out of this bad boy in a weekend or two.

That's a great looking build. I too have some concerns about the height of the firebox hole, I think I would put the exhaust on the same end as the firebox and direct the smoke down underneath and distribute it with tuning plates. JB

The firebox outlet won't be an issue. It was placed at that level for a specific purpose. The exhaust is already cut, so this would be problem one. The second problem with making a rf with this build is the height; as you can see, if we tried to do this, we would run out of room. The tuning plates, cooking surface and exhaust would all have to fit above the firebox outlet for that to work. We didn't want a rf build. The layout we chose will disperse heat evenly across the entire cooking surface. We paid a lot of attention to the science that goes with building an efficient smoker. One of these days we'll have results to share!

TWSSB, it looks great. We need to get you some rolling stock underneath her though. You don't want to be stuck on the side of the road this summer with this rig! I am guessing you are going to be pushing 2400lbs right now. Interesting to see how the weight comes out. I wish I could have found a dual axle bunk like you scored there. Its really coming out nice!!

Looks great brother. I'm curious as well to see how that firebox exit performs being so high. Never seen or used a jambo so I'm in the dark on this one. Off the top of my head it seems that the top racks would end up being a lot hotter than the bottom racks. Well more so than normal I guess. Quite interested in this design. Great build so far. That firebox design is intense!!!
Cheers

Brought the wife out with me today...When her and my stepmother get together, they make a pretty nasty team. We had a few distractions so we didn't get as far as we wanted, but I'll always make sure we have something to feed you guys! One thing is for certain; when we are finished, you will have seen every single step along the way! Here we go: FB door isn't finished, but I wanted to show you what we're doin' here. All we have to do is cut the vents on the door and add some handles.. Made the elbow for the stack out of some leftover tread plate. It measures 9"x9" on both ends. the stack is 6" in diameter and 36" tall...stainless steel. Here are a couple shots from the inside.. We started on the framework for the storage/utility spaces. We scored the square pipe to get a good bend around the corner. This will make it look much better when we put the skirts on. This is just a random shot... Didn't get the doors done like we wanted to..I know..it's a let down.. When we cut the doors, pressure was released and the arc got wider..now we have to find a way to bend it back without jackin' it up.. Once again, I'll make sure we always have something to share. I like to keep you all updated !

Very impressive. You'll be cooking in it very soon. Can't wait to see it in action. I bet you're past ready to see it in action too. You're almost there.

It looks great and I really like how the firebox came out here. Having studied the Jambo's as well, I think you have it nailed. Its gonna cook great. Get yourself some cheap biscuits and start testing the temps on that sucker. Be sure to shoot some pictures at night with the firebox lit up. It will look great!!
