I am looking at buying the
Oklahoma Joe's Longhorn 1,060-sq in Charcoal Horizontal Smoker from Lower. I would like to knwo of some MOds I can make to this smoker to make it better. I am open to any ideas

I just bought a Longhorn and I added a convection plate and a charcoal box and it seems to be working pretty good, not to much smoke leaking out. But if anybody knows something else I can do to make it better let me know.

I live in Missouri and they have a Horizon store in Kansas City. Horizon is the company that used to make Oklahoma Joe's until they sold the company. Apparently who of the owners started making smokers which are like Oklahoma Joe's The plate was 90.00 and the basket was 50.00. The store was called Kansas City Barbeque store. But I would look up a Horizon dealer in your area and go to him. Horizon's are almost double the price of a Oklahoma Joe's

lots of threads on mods here for the OK Joe


when I had mine I just made tuning plates that laid across the bottom of the cook chamber


no need to buy something for that kind of money when its easy enough to make your own


I have seen people use cookie sheets for baffles for instance

Still trying to decide between the Brinkmann Trailmaster LE and this OK Joe Longhorn...any fresh perspectives there would be appreciated. 


If I do go with the OK Joe Longhorn I was wondering if you could clarify a few details on the mods I have been reading about:


Did you purchase the 16" Convection plate?  Link:  http://www.horizonbbqsmokers.com/accessories-1/16-convection-plate


Also, did you purchase the 16" basket from them?  Link:  http://www.horizonbbqsmokers.com/accessories-1/charcoal-basket-for-16-classic

Haven't seen much talk about having to seal the OK Joe Longhorn like I have heard about the Brinkman needing to have done.  Can any of you Okie Joe owners comment on whether or not you use sealant between the firebox and cook chamber as well as the firebox halves (like Bigg Green Egg gasket or Rutlands)?  I was thinking it was a must, but when I looked at the smokers yesterday at Lowe's they all seemed to have a pretty good seal and no real noticable gaps??

You won't know it until you see it during a smoke. Usually you can spot the leaks when you "season" the smoker. I just added the felt gasket from the Large BGE to the cooking chamber. I put it on the chamber instead of the door using weatherstrip adhesive as I did have leakage around the door. Because of the gauge of the steel used in the OKJ, you're gonna get some warpage the amount of which will depend on usage and ambient temps.


When you season the smoker, observe both temps and smoke flow. You should see how well your airflow operates by varying the top and firebox dampers. Start with wide open at the stack and vary the intake at the firebox end. You'll see where your leaks are and should be able to deal with them effectively. 


Hope this helps!

Pop, I think that Horizon plates are sized the same as the CC. If you have a Bass Pro Shop close by, they sell all kinds of Horizon stuff. Good luck and good smoking. Please let us know how you come out. Thanks, Joe

I am the new owner of a Oklahoma Joe picked up for 125. It has none of the mods which you all speak of. I had one question i was gonna get some high temp silicone and seal up doors for starters what should i use to cut the grease but not inhibit adhesion of silicone. Thnks

I have heard of folks using brake cleaner from the auto supply store. I would think that acetone would be an excellent cleaner. Don't use paint thinner, it's a petroleum base and will leave an oily residue behind that will inhibit the sticking of your sealant. Don't use lacquer thinner as it will attack the finish of the smoker. I hope this helps. You should be able to get the acetone in the paint section of Ace, Lowes, or Home Depot. Good luck. Joe

Thank you for the quick response Joe. will give it a go and gonna give a fresh coat of high temp paint too. Just as a precaution.

Getting ready to put my Oklahoma Joe Longhorn together today.  I have been trying to find the best method for sealing in between the two fire box halves, but having found nothing perfect it occurred to me - why don't I just have it welded and be permanent.  Is there some reason that this would be a bad idea?  I haven't heard anyone suggest it on here is what makes me ask, but hoping it will be a good move??  Thanks in advance for any feedback!! 

post #19 of 55
good point. Not sure why no one has brought that up. Any welders care to elaborate? Or anyone
post #20 of 55
Hope to hear good things, dropped it off at the welders yesterday! Hope to have it back by midweek and ready to season this weekend!! I will post any feedback from what I find on my end. Wish me luck!
