    My first tank type RF Smoker

    Most of the calculators available online are set up for standard airflow configurations.   Lets just say mine has been tweaked to suit reverse flow.    The length of the pipe that is suggested is what is exposed outside of the cook chamber.  I would take the pipe down into the chamber to about...

    Brisket was always 14 to 15 hours in my Ole MES as well.    Hope you have a great meal tomorrow!

    My first tank type RF Smoker

    The size of the air inlets, and the gap at the end of your RF plate will depend on the size of the exhaust.  My spreadsheet (modified for RF smokers) says you want to use about 18 inches of five inch diameter pipe.  that will mean you will need 30 sq inches of air inlet, and 25 sq inches of gap...

    Another First Brisket Smoke - 01/28/12 - Follow Along With Me

    190° might be a bit shy on the internal temp.  Every piece of brisket is different, but typically they pass the tenderness tests between 194° and 197° for slicing.  Use a 2 prong BBQ fork and slide it in the middle of the brisket against the grain.  When you pull it out it should come out with...

    Little nervous

    The distance between the rack and the RF plate has a lot to do with the thickness of the RF plate, the size of the smoker, and the use of the smoker.  The thicker the metal you use for the RF plate the closer you can get.  We use mostly 3/16 for the RF plate, and in patio size smokers we run it...

    Round vs Square Firebox

    As long as you don't short yourself in cubic inches ( 1/3 the volume as the cook chamber ), the round fireboxes are more efficient at transfering heat into the cook chamber.  As previously stated the clean out becomes more difficult, but you can make yourself a scraping tool with a radius that...

    Reverse Flow Smoker Build!

    The gap on the end of the RF plate should be about 25% more the the area you have in the exhaust.  If you are running a 5 inch pipe you have about 20 sq inches of area, so you want at least a 25 sq inch gap at the end of the plate. To find the area of a pipe you use Radius X 2 X 3.14.

    Trailer Mounted Reverse Flow with added Goodies

    You can put the top flange inside the smoker.  Weld it to the cook chamber so it sticks out a half inch and the door will close into it.  Otherwise you will need to do the fingers like the previous post shows.

    First smoker build + a few Q's

    I agree with Solar.  I would go with 3/16 on the RF plate, and make it so that you can adjust the lower food rack so that your an inch or two from the RF plate for when your going to do your "radiant" cooking.  Then move it up to 4 to 5 inches off the plate when your using it as an RF smoker. ...

    First smoker build

    Best place to start is with the various smoker calculators online.  They are excell sheets that you plug in your information, and it will tell you what you need as for size of firebox, and diameter and length of stack..  ect. This will give you an idea of where to start.  The rest of the...

    Reverse Flow Smoker Build!

    What we have found is that it is difficult to control the temp without the insulation between the two.  The box would get up to 350° without any airflow.  You could actually cool it down about 50° by opening the smoke vent from the main chamber. lol  Large fresh air vents along the bottom so...

    Reverse Flow Smoker Build!

    Things are looking good!  Did you insulate between the firebox and warming box?    I would look for a torsion axle for the trailer.  Very easy to install, and even new they are typically 3 to 6 hundred depending on configuration.  Get double what your estimated weight is.   Make sure you have at...

    275 fuel tank vs. 100 gallon propane tank

    The fuel tanks can be pretty thin, but it may be worth checking out.  Another option is to look around for yards that sell rolled steel.  You can typically get rolled steel pipe for 50 bucks a foot or less for 24 inch diameter.   For the size parties yur talking about you could easily do what...

    Smoking in Winter

    Packing blankets work well and are available for cheap at harbor freight type places.  Get a couple of hand clamps to hold it to the smoker and your set.   A lot of us smoke during the winter.  My smokers have insulated fireboxes and 3/8 inch steel on the cook chamber.  Even with that we will...

    My first smoker build . Temp help!!!

    ok so here is my take on this..   It's just a matter of airflow, which I don't think you have enough of.  Based on some rough estimates for 55 gallon drums, you have way to small of exhaust pipe.   My spreadsheet says you need 20 square inches of air inlet to the firebox (adjustable), 50 square...

    One of a kind

    It had more to do with the length of the stack, and not the diameter.  A stack that long would increase the velocity of the air so much, that I am sure it was sucking air right past the fire before it had a chance to heat.  With 6 inch pipe, the length would be around 12 to16 inches or less for...
