Consistency across the smoking chamber - simple mods

    I did a lot of reading up on pellet grills before purchasing my Rec Tec and I did note that many people have problems with actual temps vs set temps, consistency across the grates, and getting a good smoke on the meat.  I just did a long smoke this weekend on some butts and had great results.  I had read a lot about a downdraft mod that people are purchasing for around $100 and this intrigued me.  The mod is supposed to help in the areas mentioned above.  I wanted to test the theory and after seeing a mod from Pelletheads, I purchased a $3 3" elbow and used it to pull out exhaust air closer to the middle of chamber rather than from the top.  One other mod I made is pouring about 20# of fullers earth in the bottom of my chamber.  That does two things, sucks up any residual grease that misses my grease tray and helps me hold / maintain temps a bit better in sub freezing weather.

    I had it set at 200 for about an hour while putting some smoke on the butts and the steaks in the pic above.  After pulling the steaks and doing a reverse sear on them on my gasser, I bumped the temp to 230 and let the Rec Tec do it's thing.  Early on in the smoke, there is a bit of a difference from set/actual temp, and grate temp (I have a maverick prove in the rear left corner just behind the elbow.  I think the temp of the meat has a bit of play in this.  The following were smoker set temps, grate temps and meat temps at different stages:

    Set temp - 230

    Grate temp - 221

    Meat temp - 81

    Set temp - 230

    Grate temp - 221

    Meat temp - 115

    Set temp - 230

    Grate temp - 226

    Meat temp - 122

    Set temp - 230

    Grate temp - 232

    Meat temp - 160

    I then foiled and raised the temp to 240.

    Set temp - 240

    Grate temp - 245

    Meat temp 200

    I am more than ok with these temps.  I can go to bed on overnight cooks and not have to worry about my actual vs set temps.  This unit is rock solid and is very consistent across the chamber.  I think the mods have helped.  The nice thing about the elbow mod is that I can remove it in literally 5 seconds - the downdraft hood for $100 looks good, but is bolted to the chamber.

    The results:

    Happy smoking!

    I use something similar in my GMG Daniel Boone! Good mod and a decent fix for the price.
  3. I know this was posted a while ago, but I have a Daniel Boone and am wondering how the elbow is attached.  I can't tell from the pic, (I know it isn't a DB.)

    I've been using one on my DB for a couple yrs now. It definitely does help, but its not a fixall.
    I cut a very narrow "v" in the crimped end of the elbow. It allowed me to squeeze that end for a easier fit into the opening of the smoke stack.

    I also added a 6" length to bring the pipe down to grate level. However, with the additional piece, the 2nd shelf wont fit. So i use only the elbow when i need to use the 2nd shelf.

  5. Thanks! I tried crimping the end in but it still doesn't fit. Wanted to ask before I got too off the deep end, lol.
