My new project. The name of it right now (The Project)
PDT_Armataz_01_18.gif

My dad heard about a smoker advertised on our local party line for $300 on a trailer. So he gave me a call so I could check it out. Sounded promising. So I went and seen the guy and could see real quick that it was going to need alot of work and TLC. I offered $200 and he took it. Called my dad back and he said he would pay for it as long as I would cook him some Q every now and then. **DEAL**

Wohooo..

The bottom seems to be rusted out pretty bad so my father-in-law (who is a good welder) and I are going to fix that first. Then, the next step will be to add a firebox on the rounded end in the back. The question I have is, should I make it a reverse flow system or standard? I would like to do reverse flow but I have no idea of the specifications. If anyone has ever built one or has any information on one that would be greatly appreciated. Either way I am going to move the smoke stack to one end or the other.

Like I said if anyone has any ideas that would be great.
Thanks for reading and wish me luck.
 
I would say talk to steve he did just build his mini reverse flow, something tells me he will be along shtorly to jump in. Also if you need some more pics of a reverse flow let me know what your looking for and I will take some of the lang.
 
Looks like a fun project! I like the reverse flow because thats what I have, so I am biased, I guess.

If you know your diameter and length, plus the thickness of your steel, then we can compare it with the other reverse flows and ballpark some measurements for you as to the size of your firebox, and the location of a baffle, etc.

Talk Later,

Steve
 
Ok, thanks steve. I'll have to get those measurements tomorrow and will post them then. I appreciate all the help.

Walking dude- I normally do check google for everything but I posted the original message at work and did not have time before I left. Thanks for the links though

That would be great Neens. get me some from the grate area and maybe the end opposite the fire box so I can see how far the baffle stops from the end.

Did that make sense?

Thanks.
 
Ya I get it. I will get them as soon as I can but I have rain coming for the next 3 days it looks like and the smoker is outside covered. If its not raining tomorrow when I get home from work or sat. during a break I will get some good pics for you. I will throw a tape measure in there for you also to make it easyer.
 
Alright steve here are the specs. It is 6.5 feet long and 3 feet across, the steel is about an 1/8th in thick. From the looks of some of the other threads, the baffle needs to be a slight V shape and about 5in from the main grates. That is just what I took from the other threads. Anyother suggestions are very welcome.

Thanks for the help
 
Without doing any research, I will wing it and guess some here---I will try to look into this further for you, but, my first thought is that the steel(1/8") may be a bit thin for such a large diameter, although if you you make the baffle thicker, maybe that would help you with heat losses.

I have never touched a Lang 84, but I think it is similar in size(30" diam), your diameter is 6 inches deeper, so I think the smallest size firebox you could do is 24" square(which is on the 84), but possibly bigger.

The 5" spacing from the grates to the baffle seems a bit high. Again, I am winging it and its bed time for me, I will try to follow up for ya this weekend:-)

Any 84 owners out there who know the diameter of the chimney pipe and the average space from the grate to the baffle plus confirm the diameter and length, please let us know. We can always set up ratios as well to calculate a scaling of your unit.
 
Ok, thanks Steve. The steel might be a bit thicker I didn't ecaxtly measure that part of it. I was thinking on the Baffle the lowest point in the V to be 5" from the grate and the the top to 2" or 3". That is totaly a guess. Any idea on how far down the barrel the baffle should run, not quite sure on that part.
Alright - thanks for the info so far.
 
The baffle runs down the barrel until the tank starts to curve, this is where the propane tanks have the head ends welded. In the case of the Model 60, it is about 7.5 inches from the center of the curve to the baffle end.

The bottom grates actually set on the baffle weld where it meets the outside tank wall and then of course, the grates are level and the baffle is not because it pitches to the center. At the point in which the steel plate is welded to the center drain angle iron is about 2.5 to 3 inches from the top of the grate on a 60, so maybe a bit more on the 84. To summarize---I think what you really need is the angle or the pitch of the baffle which is about 1 inch per foot towards the center. It might be helpful to lay it all out on graph paper:-)

The baffle location is roughly 2/3 the way down the chamber. In other words, the level line drawn from the baffle weld where it meets the outside tank is about 2/3 the way down the vertical line(diameter).

Talk later,

Steve
