    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    Got past a busy period at work, hoping to be able to post a version of this that you can access from my webserver in a few days, so that folks without Windows can try the tool. I do have the visual representation part done, so it shows you the dimensions of the tank, to give a better idea of...

    Ground up a batch of deer meat for burgers, fell apart

    I definitely am picky.  As much deer fat as possible is removed, all bloody sections as well.  On the deer and even the pork butts, I look for the glands to remove them.  Some butchers seem to remove them, and others do not. I think next time I won't do the 5/32" grind, but run it once through...

    Ground up a batch of deer meat for burgers, fell apart

    When I shot the deer, the temperature was relatively warm out, we had to get it processed pretty quick.  After butchering, I let it soak in a cooler with ice on top (and the drain open) for several days.  My in-laws who have more experience preparing deer meat suggested that For all my deer...

    Ground up a batch of deer meat for burgers, fell apart

    So, you might run only 30% venison to pork in your case for burger?

    Ground up a batch of deer meat for burgers, fell apart

    I added 30% pork trimmings.  If you figure it isn't 100% fat, I guessed it ended up at about 75% lean. I did not try pork shoulder this time, that is what I usually use for my sausage, and I have often done 60% pork to 40% venison (in a 25 pound batch, 15 pounds of pork to 10 pounds venison)...

    Ground up a batch of deer meat for burgers, fell apart

    This isn't precisely smoked (although I have smoked some hamburgers that tasted quite fine), but I'd like to be able to successfully grind my own hamburger meat, venison, or otherwise. I've had other meats do this to me (when I ground up some other beef for hamburgers), so I'm guessing it has...

    novasbc's 250 gallon propane tank build

    Yes, thise calculations are what I have been going by, and as you see later in the thread, I dhared the program I built in order to try and make it easier.

    Thanks, that is a good explanation.  I think I'm going to work something up in my calculator, and include the basic ideas in a help popup or something.

    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    It's easy to overanalyze, especially for me, I like to do things as right as possible the first time.  However, this is a lot of firsts for me, first pit to build, first time welding, cutting metal, etc.  I ended up just buying the metal to finish up the frame, and some expanded metal to put on...

    novasbc's 250 gallon propane tank build

    I think I didn't do this right, doesn't make any sense, more late night math. I have the value of the "Area required at the end of the RF plate in square inches" (266.53 sq inches),  from DaveOmak's thread.  Do I have to calculate this with the ends of the tank as part of the equation, or do I...

    By the way, if it would be better for me to start a new thread rather than adding to this one, let me know, I don't mind.  I figured I'd discuss it here because this is all based on the calculations in post #1.

    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    Thanks, that helps a lot!  I guess it would be helpful to include in the description what the baseline is, that you need to watch for a 15% deviation.  I went and measured my father-in-law's tank, and while it was different than mine (my ends are much closer to flat than his), the diameter of...

    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    So, the point of the calculation is to get a value for the size of the opening from the firebox all the way until it gets into the cooking area.  This size should remain the same throughout, too small, and it gets restricted, and too big, it likely causes currents. I can see that a longer tank...

    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    Yeah, apparently I shouldn't be doing math at 1:00 in the morning after driving.  It is patently obvious in the morning that it is the same as doing π*r²*h, but since you are using the diameter instead of the radius, it would end up with quadruple the value it should be, hence dividing PI / 4. ...

    novasbc's 250 gallon propane tank build

    I've given up the idea of putting this into some sort of CAD program for now.  Here is what I am tentatively planning to do: Just recently on another thread here, I realized that I have a "wide/fat short CC", because of my tank design (previously I didn't connect the dots).  I may have to...

    Standard Reverse Flow Smoker Calculator... by DaveOmak and others... Ready to use.. rev5.. 6/19/15.

    How much of an increase or decrease are you talking about, and of which number?  I assume raising or lowering the value of 0.7854 you use initially, to calculate the volume in cubic inches?

    Short and fat 250 gal. reverse flow, advice on adjusting parameters for airflow?

    How would you quantify this to be a general application? His tank dimensions sound similar to mine and I hadn't altered any od my calculations based on it. If I were to update the calculator I posted later in your thread, is 15% a magic number for what I presume is true for the older tank...
