How is it plumbed in on your timberline 850? Is it the pellet tube or the full setup? Pictures?
In the case of my Timberline 850, I drilled a 1 1/8" hole on the left side, lower left. Believe me, I was not thrilled about drilling into a brand new Timberline. But that's how the SmokeDaddy works -- you need a hole to route the smoke into the grill. I got the drill bits, made a brace from an old 2x4 -- and bit the bullet -- drilled in -- and it worked.
Then you insert the SmokeDaddy (Big Kahuna, in my case), and install the (included) air pump.
Fill the SD with charcoal and wood chunks -- and boom -- perfect smoke for 1.5 hours or so. Easy to refill to keep going. The air from the pump blows across the top of the SD and down into the SD -- and essentially forces (lots of) smoke into the Timberline.
Is it ideal? No.
Does it give an intense smoke profile? Yes.
Is the profile similar to a Pit Barrel or UDS or Weber Smokey Mountain (I own an 18" WSM -- and built a Big Poppa drum from scratch several years ago)? Yes.
I messed around with pellets -- Lumber Jack, Cookin', Traeger -- but none of them came close to the smoke flavor from the Smoke Daddy.
I messed around smoking tubes and triangles and rectangles -- and while they're good (and they do work to some extent) -- the smoke from these portable things is not comparable to the SmokeDaddy cold smokers.
If there's a better way to get smoke and smoke flavor in a pellet grill -- I'm all ears. But for me -- the SD Big Kahuna worked perfectly.
Plus, SmokeDaddy is a pleasure to deal with. I had an issue with a missing part -- and they sent it out -- no questions asked -- 24 hours later, FedEx.
No affiliation with SmokeDaddy -- just happy to have the Timberline 850 (which works fine after 50+ smokes -- zero issues -- including wifi) with the SD.
My next smoker -- without a doubt -- is gonna be the new SD Pellet Pro vertical smoker. Gotta wait a bit -- maybe a year or so -- but that's gonna be my next smoker. Then a Backwoods.
