Hey guys,
First, they changed photobucket and I don't know what size to make the pictures, in fact I have never figured out how to put an avatar picture up? sorry

I had a place build this for me down south in July and I have tried to get it up to temp twice and no luck. I will not call the builder out here unless you think I should. I wanted to be able to smoke whole hogs and thought it would be a good idea to be able to have a lower temp in the middle, so the loin and ribs would cook slower and also be able to set it up reverse flow for other cooks. I gave them my ideas and this is what they came up with. I sent them an email last week and have not gotten any response yet. I work 80 plus hours a week and really haven't had time to figure this out until now. It may be me, but? I added a Guru set up to monitor and steady temps before I even fired it up. It pulls the smoke through but it's not pulling hardly any heat. I started it with the vents wide open and have adjusted everything in every way I believe and no success. I had suggested that the fire box be directly attached square to the cooking chamber. I have customers that ask for things that won't work for them and I always make sure to let them know before they have a problem with their order. I sure don't send it out and let them deal with it. It's called customer service. I hope you all can help me out with this. I have an angle grinder and a capable welder here. I was hoping I was avoiding some trial and error by paying somebody that knew what they were doing. I set it up with tuner plates and a water pan just above the intake. I was thinking maybe longer stacks or the fire box lower?

I would say the firebox needs to be lower. As you know heat rises and with the transfer tube coming out the bottom of the firebox I could see it having trouble drawing heat over.

Longer stacks may help some.


Of course I am no expert.

Thanks, I was thinking longer stacks might help the draw and the lower box as well, without the 45 degree throat. I just figured I would get some input before I get the angle grinder out. The two drains also don't have shut offs either.

I would build a lower more rectangular firebox something like a DP has. I would leave the exhausts at the height they are I do not think adding to them will help your problem.

It does have some design flaws and like what has already been said, a near horizontal draw is difficult at best. I have a solution that will work, but you may not want to do it. Bottom line ...... the firebox is just too high.

I like to keep things simple when troubleshooting a cooker so lets first take a look at your draw. To test draw problems you will first need to pressurize the firebox. That sound difficult but it is really quite easy. Here is what you do......

#1 GO to Walmart and buy you a 4 inch personal fan (metal cage and blade) it will cost you $10
#2 Close all your intake except one door intake and fire up your smoker .
#3 Place the fan about 8-10 inches away from the wide open air intake and turn it on low blowing into the firebox.

This should take care of your problem. If you need to put the fan on high then you have bigger problems.

If it works great then two things can be done without moving the firebox.

#1 Mount a fireplace stove blower to one of the door intakes and PM me as to which one and how to make it adjustable.

#2 Mount a 90 degree 5 inch elbow from the top rear of the firebox to the middle of the crossover channel. This should increase your temperature but will not do a lot for your draw.

Having the exit of the firebox so low effectively reduces the useful volume of your firebox.
As others have said The firebox needs to be lower in relation to the cook chamber so that the smoke exits at the top of the fire box.
You may find it easier to raise the cook chamber instead of lowering the firebox to achieve the same goal.

As you have already done it, you simply need to add a small fan instead of changing position of fire box.
50 CFM Fan, $10, AC/DC adapter $10, air mail $10, total $30

or you can buy a Li-Ion battery from eBay, 12 VDC 4000 ma.h price is around $10, charger $10。 You may need a potentiometer too, price $10

I think I'd go with raising the cook chamber enough to make that snout come out higher on the firebox, assuming that you want to keep that configuration.

The best plan would probably be KAM's original thought -- lower and more rectangular firebox.

I took a look at this with my local welder/friend, who is so busy making trailers that I wasn't going to bother him with the R&D of a smoker, and we came to the conclusion that we would need to raise the cooker as to not interfere with the integrity of the trailer portion. Then square up the fire box. So much for skipping the expense of R&D. I will need to totally chop this up with the plasma torch in order to make things right. January's project along with the food truck interior. Thanks for the input. I kinda new the solution. Just wanted to see if anyone might have a more clever solution.

Charlie,

If you're gonna raise the cooker up, I don't think you necessarily need to square up the firebox. I kind of like that look. If you raise the cooker up, it will most certainly draw better which may fix your problem. Depends on how much fiddling you want to do with it.

Good Luck,
Ed

I still believe a shorter longer firebox will line right up on the back without tearing up anything.
