Well been plugging away. got the CC doors mounted,All the 1/4 plate welded on the cc door and end and back pieces to make square doors, hinges on. Looks really good
Well, got this far. Got a little to go. I appearantly smashed gasket to much as I am getting some smoke out the door. I will address that next chance I get.
Hmmm, I got a question for the experts, I fired it off today using the method in the stickies above, and it came up to about 240 or so and I let it ride for a bit. It held fairly stable and then I decided to try and let it stretch its legs and get hot to clean it out a little more, but it really struggled and wouldn't climb any higher. I started with the 80 gallon tank, squared the doors, added the 20"x20"x20" fire box that was about 115% which is a little large, and used a 3.5" ID pipe 36" long for the exhaust, it shows to be about 6" short on exhaust. Is the low temps a correlation to short exhaust? Thanks
Edit: this happens to be the same picture ID posted on page 1....sorry
The 80 gallon build I just finished has about the same size fire box.. It also has about the same size squared off doors. What do you have for the intakes on the firebox?
For what it's worth.....My exhaust is a 4" square iD about 27" tall with 2- 2 1/4 x 8" firebox dampers. That smoker will run 375-400 when I open it up. The fire basket is smaller so I can only use 14" lengths of wood but 4-5 3" diameter pieces with dampers open, will get it up there
Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life
An easy test for inlet air is crack the FB door open. To test the stack length add cardboard roll to the stack top if you don't have anything preventing you from doing that. I wonder if you are using an fire basket? How about letting us see some picks and maybe we will see something.
Current Smokers: Backyard RF Offset and Hybrid RF Offset trailer rig with Cowboy cooker and fish fryer, always room for more........
I am using a fire rack made from angle and expanded metal. My cook chamber opening is exactly the size the calculator suggested. I will add a cardboard extension tomorrow and see if that helps. I will get more pics tomorrow and see if we can figure it out. The top of my firebox showed 425 degrees with an infrared thermometer and cook chamber showed real close to the thermometer readings in the door.
Something to think about is the placement of the air intakes. Rod r after has a good point to crack the fire box door. But it can lie to you. If the intakes are not positioned correctly you will draft above or beside the fire and actually stuck the heat out of the fire. Your air needs to enter the fire from the bottom. This is a very common problem when you can't get temps up high.
Same thing today. Won't climb as I thought it Would. Tilted rack to gain bottom clearance and nothing. Added extension to exhaust and nothing. Struggled to 250. Going to measure my FB to CC opening to see if that is an issue. Agh!!!!
Cant figure out how to get pics right... lol
