Has anyone ever built their own gravity fed smoker? If so, any good pics of how it all works?

Jerry has...hopefully he'll chime in soon...he's got a Gravity Fed Stickburner that is pretty slick.

I love mine! Wish I had done it years earlier.

But does it give that stickburner flavor?

Whether or not it does, I sure do like it. One of the slickest offsets I have ever seen.

did you ever give its well deserved coat of paint?

First we need some definition of the parts.

1. The ash box and fire grate.


This one is 1/4" steel with 5/8" rebar grate

2. The heat transfer tube



This one is 2" by 4" by .105 304 stainless steel.

3. Then we need a chute.


This one is tapered 3" by 5" to 3.5" by 7". The chute is made of .105" 304 stainless

4. Heat transfer tube is connected to chute.



The chute and the heat tranfer tube is finished.

5. Re-inforce the the lower section of the chute with 1/4" stainless steel.



6. Attach the Chute and Heat Transfer Tube to the Ash Box.



Almost done.

7. Some finishing touches and a view of what the inside looks like.



This component is done.

The fire burns in the bottom of the chute. The top of the chute is covered with an airtight door which prevents combustion from moving up the chute past the top of the heat transfer tube. The chute is filled with charcoal all the way to the top of the chute. Heat and smoke move through the Heat Transfer tube into the cooking chamber. Ashes drop down into the ash box.

This is just another application of the basic Fire Triangle. We limit and control the amount of fuel. We allow a free flow of air with only minor controling needed to achieve complete and clean combustion. A thin Blue smoke is a no brainer.

Gravity moves the charcoal down the chute and replentishes the fuel supply. Ashes fall out the bottom.

Air flow is from the ash box up the chute and out the Heat transfer tube.

Thanks goes to the Smokin Okie for the help understanding the fire triangle and how to get that much covited thin blue smoke.

I generally add wood in the bottom of the ash box and mix flavors as the spirit moves me. It has a wonderful smoke flavor. I use only lump oak charcoal. Brickets have too many additives and are naturally self smothering which leads to smoldering fire and white smoke. White smoke tastes bad!

Sorry that it took me so long to get you an answer.
