My SFB got a make-over!

post #1 of 6
Thread Starter 

So a few weeks ago I posted a thread about ideas of what I wanted to check out for a 250 gal tank I stumbled across. Since then I was able to make some changes to my SFB to make it into a Reverse-Flow. All of the pictures are posted here, http://s616.photobucket.com/albums/tt250/fobar22/Smoker%20ver%201/ but I will put a few in the thread as well.




I added a .5" angle iron to act as a drain channel for the drippings, they flow into the tube that goes to a steel can under the smoker.



You can see the cover I welded over the old exhaust hole, and the panels that were added to move the smoke across the bottom.




I brought the exhaust all the way down to the grate




I also made a jacket out of a wool blanket that I had laying around, this thing took the most time so far!


It took me two weekends to make all of the changes and I didn't finish till today (Monday) and I couldn't wait to use it so I went straight to my supplier and picked up two Boston Butts to go straight onto the smoker!


I am still relearning the smoker as the cook continues, but right now it is 65F and a little breezy, with the cover on the thing I am having a hard time keeping the temperature below 250F. I guess I can start using less fuel...


It took a while to warm up completely due to all of the bricks I have in there, 45 all together. They line the full length of the bottom, and the side furthest from the fire. There are also bricks in the firebox to help insulate that. Overall I am extremely satisfied!


Not too bad for working out of the bed of my truck in an apartment complex. I know there is a strict no-grilling policy that I keep ignoring, I didn't want to push the whole welding part, so I had to do that on the weekend when no one was around...

Wow!  Nice mods!  How ya gonna hide all the smoke from the "no grilling police?"  police2.gif  It's not like that thing is a tiny, inconspicuous rig!!!!

As for hiding it, I don't think that is possible. I have had a few run-ins with the maintenance guys, but I have dodged the bullet so far. But I'll be moving in about a month, so soon it won't matter. And it turns out that the fire inspector is a fellow smoker, so he doesn't mind it at all.


Thanks for the complements. There are a few things I'd like to fix based off last nights cook. I need to re-weld/rethink the fat drip tube, I have a sizable clump of fat hanging about half way down on the outside. So I must have a leak or something, I could only imagine what it looks like under the panels inside the smoker... Also I noticed that the temperature in the exhaust is a good 10 to 15 degrees hotter than everywhere else, I am thinking this is from the fire having direct line of site on the metal right under the exhaust inlet, I will add some metal to stop the radiant heat from the fire going directly under the exhaust tube.


Also I am still working on some electronics that will monitor the air temperature and adjust the air inlet every 30 seconds or so. The prototype is looking good, just a few more bugs to work out.


I might also increase the size of the air inlet. For the first 2-3 hours, I had to partially open the ash collection tray to let more air in, once everything warmed up though I was able to control the temperature through the smaller single air inlet. I figure doubling the size of it should be sufficient and easier than adding a second, because of the electronics and all.

Looks good. We have another member that has issues using a patio fire.gif
