    I ended getting a wild hair up my butt this morning and did the mailbox mod. It is working like a charm. However, I am not getting enough air in the cabinet and all my smoke pours out the mailbox unless I have door cracked. When the door is cracked I could get tbs all day long. I am thinking I just need to add another vent in the smoker since the only one on my smoker is on the rear upper portion of the cabinet. So here is my question. Where should I put a new vent to where it will have the same affect as having the door cracked and it will help pull the smoke from the mailbox?

    I'd think any added exhaust will do the most good for air and smoke flow if it's in the top of your cabinet. You might try just expanding the size of the original vent...a larger diameter exhaust vent will surely increase your air flow. My thinking is, increase by a small amount to start, then test run it to see how it works. Then you can increase again if more is needed. Might seem like a pain, but remember that you can always make bigger holes, but you can't really go back to smaller if you end up with more airflow than you need.

    Don't know if that helps or not, but there's my .02...good luck!

    That sounds like a good start. Tonight I am going to bring the mailbox level with the cabinet and try to shorten the travel length for the smoke and see if that helps too

    Go to the search bar at the top and click on the smoker build section. When you find the type of smoker that you have, there should be a ton of folks to help you with the problem. Sorry, but I don't know anything about verticles.

    Good luck, Joe

    I don't know If I would start cutting the cabinet up... first try to make a stack for the exhaust vent to get it up over top of the cabinet and help create a draw... Also it looks like the holes in the mailbox could be bigger to get more air through there.... see what others have to say first....
     
  7. My thoughts are that if you bring it level "smoke rises" it may not travel into the box. you said if the door is open all is good, so some air flow near the bottom might be the answer ?? if you drill holes as said above maybe keep the lower holes the size of a cork so you can add or remove as needed.

    Again Just My Thoughts,

    Thanks for the help. Im not sure the best way to try and make a stack due to the style of my vent. I am kind of hesitant about drilling holes on the cabinet since I had to drill a big one for the smoke from the mailbox. If thats what I need to do then I will. Also, I was kind of thinking the same thing about drilling the holes about level with where the smoke comes in except on the opposite side of the cabinet

    Using a step drill, around the top of the side walls of the smoker, drill 8 holes.... 2 on each side... I would drill them about 3/4" of an inch in diameter and down about 1" from the top of the smoker... Refer magnets can be used to plug the holes that are facing into the wind... just in case you need to plug some....
     
  10. Freezer Magnets ,,,, What a great Idea! way better than a cork (more sanitary) Thanks Dave for the Tip.

    Do I have to use a step drill or will a hole saw suffive?

    Also, will I still be able to maintain heat fairly easy with all the holes?

    Yep......


    Probably easier than without.... Probably ought to drill holes in the bottom of the walls also... 1 hole in the bottom of each wall to help with the air flow...

    When you get all done and fire it up for it's first run, when done, you should notice better flavor in the food... just a guess....
