Title: Exhaust chimney for smoker to increase draft
Post by: Lonzinomaker on August 18, 2018, 04:10:19 PM
I had been using a piece of 2 in aluminum flex tubing for an exhaust chimney to help draft a little and to keep the smoke out of the smoking area. It fit over the top vent of the smoker fairly well, but it wasn't very steady. I have been trying to figure out a way to make it steadier and heavier at the base so it would stand up. I also wanted it to look nice. 
While I was plumbing a new drain for my sink, I saw the perfect pieces that when put together looks nice, is heavier at the base and not very expensive.  I used a brass 1 1/2 in adapter and a 2 in X 5 in long chromed slip joint extension. Put together and tightened a little keep them together.  I also cut a notch in the bottom so it won't pinch the thermometer cables and not wobble.
The first pic shows the complete chimney with notch on bottom/side. Second pic is closeup of notch.
Third pic is my Amazin tube with a 2 in ground clamp on it. The clamp elevates one end and allows better airflow around it so it stays lit better when doing cold smokes.  I could use two, but one works just fine.

Nicely done. Has the quality of the smoke improved?

Overall the quality of the food is the same, except when using the Amazin tube for cold smokes (think cheese and jerky), then it is better because the tube stays lit better.  The chimney also helps keep the smoke away from my thermometer that I like to sit on top of the smoker and lets it disperse away from the smoker area better.

Does this help with standard smoking( ie at 225) in regard to keeping the Amazon tube or similar devices lit and smoking? 

I was unable keep an A-MAZE-N-PELLET-SMOKER smoking for more than about 20 minutes in a Smokinit Model 3

Thanks

Both ideas helped my tube stay lit. But it wasn't until i raised the end that the tube stayed lit consistently.
