    Best Way To Seal an OJ?

    Hi All,
    I decided to take the jump to get into some low-and-slow smokin', and am awaiting delivery of an OJ Reverse Highland Offset. Things take a bit longer to get here to Melbourne, Australia! I just hope it's not floating around in a container in the Pacific!

    You might all think of it as a COS, but Downunder the RRP is 1,000 Australian Pesos, which is about 700 US bucks! Phew!

    Anyway, I've read everyones suggestions on mods - great info, thanks! I am planning on some sealing prior to first fire up and am wondering about types of sealant to use.

    I've got some Lavalock RTV650, 5/8"x1/8" firebox gasket tape and 5/8"x1/8" smoker seal gasket tape on order as well.

    I had planned on using the RTV650 on the joints between the firebox and smoker chambers, and between the two halves of the firebox chamber, as these joints don't really move or open. Then I was going to use the tapes on the doors.
    However, I have seen some suggest using tape between the firebox halves and between the firebox and the smoker instead of RTV650.

    Any thoughts?

    Tape it all up, as much as ya wish...
    It'll all burn off, in time, anyhow.
    I wouldn't personally recommend worryin too much about it, despite what th internet might indicate.
    Th firebox tape's been gone offa my OKJ Highland fer goin on two years.
    I cain't really see as how it cooks any different.
    I can generally still keep 5-10° balance from side to side, runnin straight up Hickory wood.
    Mebbe I could smooth it out some, runnin charcoal briquettes? I dunno, might try some time, when I'm powerful bored.

      This new map illustrates how the ducks went on to rule the high seas
      Scientists have been tracking the toys' movements for information about the great ocean currents, which affect the planet's overall climate.

      It all began back in somewhere in the middle of the Pacific Ocean a consignment of First Years bath toys, including bright yellow rubber ducks, were spilled from the Greek owned merchant ship Evergreen Ever Laurel during a storm.

      So with a little time and a nice salt brine your OJ might still show up.

      I recommend running it a few times before you put much work into sealing it. Because it's a mass produced piece, each unit will vary a bit on fit and finish. You may not need to worry about sealing or you may want to break out the RTV. Also, don't go overboard with baffles until you get a second thermometer in there and see what it does without any baffles. I went overboard making my own baffles and ended up not using anything but a 6" wide piece of steel slid all the way to the firebox end to block the direct heat. I consistently run within 5-10* from end to end. This is all on a Longhorn, not the reverse flow. I bet you'll get even better results from the factory on that. One piece of advice Mr B gave me is that this is a stick burner and just doesn't perform as well with using only charcoal. It's a great middle level smoker, enjoy!

        The only thing that I may say against that is that if he does want's to seal it, it will be easier before it gets grease and soot build up from cooking...

      Yes, I'm thinking it will be easier before smokin' and greasin' it up, then pulling it apart again...

        Well, I finally managed to get my smoker. Must have washed up on a beach somewhere!
        I sealed it up, did my first smoke, and wouldn't you know it: virtually too hot! I'm aiming at 105 deg C (225F), and it's hard to keep it that low. Have now added a minion maze, which seems to be helping.
        I was pretty happy with my first cook-up... Delicious! Pretty good for a COS!

        Now here in Melbourne we're in hard lock-down, not allowed out, curfew 8pm-5am. At least I can get some decent meats delivered! Nothing left but to do but start cookin' again!

        I got an Inkbird IBBQ-4T four-probe wifi thermometer - fantastic for following the meat from inside.

        If you have a Weber Kettle, you need the Slow 'N' Sear


        The Slow 'N' Sear turns your grill into a first class smoker and also creates an extremely hot sear zone you can use to create steakhouse steaks.

        The Good-One Is A Superb Grill And A Superb Smoker All In One


        The Good-One Open Range is dramatically different from a traditional offset smoker. By placing the heat source behind and under the smokebox instead of off to the side, Open Range produces even temperature from left to right, something almost impossible to achieve with a standard barrel shaped offset.

        Griddle And Deep Fryer In One


        The flat top does the burgers and the fryer does the fries. Use the griddle for bacon, eggs, and home fries. Or pancakes, fajitas, grilled cheese, you name it. Why stink up the house deep frying and spatter all over? Do your fried chicken and calamari outside. Blackstone's Rangetop Combo With Deep Fryer does it all!

        The Pit Barrel Cooker May Be Too Easy


        The PBC has a rabid cult following for good reason. It is absolutely positively without a doubt the best bargain on a smoker in the world. Period. This baby will cook circles around the cheap offset sideways barrel smokers because temperature control is so much easier.

        Our Favorite Backyard Smoker


        The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing.

        The Cool Kettle With The Hinged Hood We Always Wanted


        Napoleon's NK22CK-C Charcoal Kettle Grill puts a few spins on the familiar kettle design. In fact, the hinged lid with a handle on the front, spins in a rotary motion 180 degrees. It's hard to beat a Weber kettle, but Napoleon holds its own and adds some unique features to make the NK22CK-C a viable alternative.
