A friend had a smoker/trailor built....looks to be half of a 150-200 gal tank ..and being the great friend he is..gave me use anytime.. (he is out of town on vacation so I can't ask him questions but I do know, he is new to smoking and has never used it.

Tonight is the third time I have fired it up, but the first time I have r eally taken the time to try and figure things out.

It is a crossflow type and everything looks right to my untrained eyes..firebox looks low enough, stack looks long enough. .


1st time I used it I got asked to do a cook for a benefit/fundraiser...I have done a lot of smoking(mainly with smaller units) so day of event..I build a fire and wait for the heat to come up and then get the 9 briskets ready to go on....2 hours later and have a nice bunch of coals...and 190 degrees! We had 20 mph winds with gusts almost 30 and was raining off and on....I thought the wind/weather must be robbing my heat... so I broke out a fan, aimed it in the firebox...and hit 250 fast and cooked away...kept heat right by using fan ..


2nd time was a couple days ago...new a few folks wanted some meat smoked....gather up meat....built a fire......just under 200 degrees (according to gauge in top of smoker....shelf in the middle was running about 10 degrees higher on the end away from fire box..25/30 degrees end near firebox..

Lots of smoke no heat....so pulled out another fan

Open fireboox door wood flames up in 30 seconds or so..shut dor flames die in about the same amount of time....

I will try and figure out how to post pics cause I know you will have to see it

Borrowed it tonight to play with and heat up a precooked ham for the mother in law...

Open fire box door...load it up and build a fire....200 degrees...

There is a round vent door below the main firebox door.....wide open
There is a sliding gate in the bottom of firebox (not sure if this is for airflow or empting ash) played with it...no change in burn that I can tell
Is there something I am missing/ doing wrong? Is there sometging to check or test? Any ideas welcome while I play with fire and tey and figure out how to get pics on here

Thanks in advance

Looks to me like not near enough intake, and ash buildup doesn't help either. The experts will be along soon....

If heat is coming up when you open the door then your air intakes are probably undersized. Use the door for the air intake and vary the size of the opening to maintain temps. Your firebox to smoke chamber opening looks either a little small to me or that it is too low if the smoke is coming out under the smoke chamber, but it could just be a visual thing. More pictures of the right size would help.

That right there seems to me to be the culprit of your troubles. The FB to CC opening looks much smaller than I think you would need, and the heat is hitting the vertical deflector plate and rolling in your FB.

Measure your volume of both the CC and FB, then use the calculator to figure out what your FB to CC opening should be. Remove the vertical deflector plate and make it sloped into the RF plate.

This is just my opinion and I'm sure the regulars will be on shortly for more advice. Good luck and smoke 'em if ya got 'em.

Yep X1 ..... You will need to cut into the cooking chamber (about 10 inches) and install a curved deflector welded to the bottom adjustable RF plate. This will allow the heat to enter the chamber and still move along the bottom of the RF plates.

Imagine the top curved part of a 20 gal propane bottle.... That type of slope.

Agreed on the firebox to cooking chamber opening being to small as well as the intake. I would also look into a larger diameter shorter exhaust. I would like to see some pics of the cooking chamber below grate level before I said how to proceed with my opening.

Okiecowboy, from what I am seeing you need to increase the opening into the cook chamber and raise the R/F plate to that height. This will mean a new plate but in the end the cooker will perform as it should.
I will be glad to run the numbers for you if you like. I will need the cooking chamber size as well as the firebox size.

Thank you all for the advice and help...

And KAM this may sound dumb..but what measurements do you need of cooking chamber...length, width, diameter? Is that it?

The diameter and length of the firebox.
The diameter and length of the cooking chamber.
Another measurement that would help is the distance between the top of the firebox and the bottom door cut. I noticed the door is hinged on the bottom.
