Slow motion reverse flow 300 gal.

Discussion in 'Reverse Flow' started by dragons breath, Feb 16, 2012.

  1. Woo .....  Look what I just got!


    My wife said I'm going to build one for my son. He's already happy.

    This one looks like about 300 gal. more or less. it's 30" diameter and about 117" long including domes.

    Any help in laying out the end cutout is welcome. I think I'll do a more conventional reverse flow smoker.

    The trailer is a 28" camper with 3500# axles. Plenty heavy enough for this build.

    I'm also planning to have a grill at least 4' x 4' at one end, probably the front.

    Still have to locate at least 2 sheets of 1/4" plate, but it will come.

    I am 100% in and following this. I don't know how you gonna top your other build but I gotta watch and see. [​IMG][​IMG][​IMG][​IMG]
  7. Thanks everybody for the moral support. This one will be slow because I have go to work. Last build I took off over 2 months. Makes a lot of difference. We been talking it over and the center fired unit works so well that I'm probably sticking to that design.

    It'll be fun though.

    WOW! you a glutton for punishment. I can't wait see you start on this one. You'll probably top your first one.  I too want bigger one.

    Good Luck

    I'm tuned in to this build!
  12. Wait a minute! Hold on! Woe woe woe!!!

    This is your wifes idea? Really?

    How can we go about introducing my wife to your wife?

    All I get from mine is: NOW what are you doing?
  13. Unbelievable huh?   Oh btw you don't want your wife to get together with mine.

    I'm also excited to see where you go with this one.  As for your fire box lay-out, I have two ideas for you.

    1.  Cut the dome completely off and weld a 30" + wide piece of plate steel that extends both above and below the tank.  This will facilitate having a warming oven above the firebox.  Of course while the end is off, you can easily install the plate for the reverse flow, but I would not weld the plate until the end plate is on to avoid warping.  The dome is not scrap!  You can use this for a large BBQ grill.  Check out the website below for some ideas.  As for the depth and width of the Warmer /firebox, I would make mine large enough to accommodate two steam pans sitting side by side on a single shelf.

    2.  You can use a laser that emits a level line to cut the horizontal notch  and a pipe-fitter's pipe wrap around to mark out your longitudinal line around the tank.

  15. This should be a good one.
  16. Thanks for the ideas subvet. Using a laser level to layout the cut out lines is a great idea I hadn't thought of. I'm still kicking around some ideas and it's good to think it through before the plasma hits the metal. A warming box is definitely in the mix as of now.

    Dragons Breath, morning.....  When I built a boat, I learned to transfer dimensional measurements to a curved surface using a plum bob....   With the tank level, plum, square.... draw the dimensions of the piece to be attached on the ground or the trailer bed.... with a plum bob following the dimensional lines, mark the tank using chalk....  worked for me....  Then you can reverse procedure once the tank is cut out.....  Lay the piece of steel under the tank....  using the plum, trace the cut out and transfer those marks to the steel plate....  Both vertical and horizontal dimensions will readily transfer.....  kind of like using a "compass" pencil type, to transfer dimensions...  I think there are probably "new" ways to do what you are seeking...  this is "old school" to say the least.... I'm an old school fan myself.......  Dave
  18. Thanks Dave. I understand what your talking about. I do sheet metal layout and what you're talking about is essentially triangulation which uses math to get the same result. Old school works just as good as new school and because it is full size layout you have less chance of error. My son kind of likes the mid located firebox at this point so we'll see what happens. We even found a solution to a mid mounted warming box. The unit gets large but with this trailer that's not an issue.

    Liking this. Looking forward to more!
  20. I'm finally getting started. Here's a photo of the hinge I'm putting together.

    I'm using 1" as the hinge pin size. It'll never wear out.

    Wouldn't you know it, as soon as I get started it starts to rain, but I'm used to working outside These mobile umbrellas come in handy.

    The support beam on this side is a little low and my head found it.

    I have decided to build a similar smoker to the last one as it works so well.

    Planning on smoking around 15 turkeys for Thanksgiving.This is uncharted territory for me. Gonna require a lot of BTUs.   Wish us luck.
