Hello to all. I'm new to smoking(the real BBQ). But I've been grilling for years. I read a lot about smokers on the web. I decided to find me a used ECB(el cheapo Brinkman)Brinkmann Sportsman and use a Weber Smokey Joe as my Firebox. I want to share my project with all of you because it may help someone out there who is thinking about doing the same thing. Some details for this little project: used brinkmann: $20 used Smokey Joe: $5 When I first tried the smokey joe as my firebox. the temps was so high because of the large gap that the smokey joe had with the larger Diameter brinkmann. So i decided to find a solution. Solution: Coiled copper(soft) tubing: 3/4 OD - 4 Ft length (found at Orchard Supply Hardware. sold by the foot $3.72/ft) I'm not sure how the soft copper will hold up the temperatures inside the smoker. I left the ends of the coiled copper open, to let trapped air escape(i may seal it up later and just drill holes to the underside of the tube) Riveted to the Outside lip of the Smokey Joe - using aluminum rivets. Modded Smokey Joe inside the Brinkmann Sportsman. It's a pretty good fit. I'd say it's almost flush. The only thing is that the flat head screws for the Legs do rub on the copper piping when you lower the Brinkmann down. But not to the point that you can't slide the Brinkmann down. I hope this helps someone out there trying to seal the gap of the Brinkmann Smokey Joe Hybrid smoker. All this is to help achieve the ability to control the temps in the ECB.
