I got a Smoke Hollow 30166E at a close out deal a few months back. I bought this one for the convenience of an electric, small cooks, jerky. There is really no air flow in this cabinet, there is no air intake aside from holes in the base and leakage around the door. The top has a very small vent less than 1/4" diameter.
I had some 3" exhaust pipe in the shop and matching hole saw so I went to work.
3"air intake on cabinet lower left side
3" exhaust / stack on cabinet top rear right
Made flanges from some #10 sheet, tacked pipe to flanges and sealed with some high temp sealant
Fabricated a butterfly valve for the air intake so I could close off cabinet if I needed it and control air.
A few sheet metal screws and more red sealant under the flange.
Sealed inside as well. Had to bend the bottom grate out of the way. It's attached by bolts in each corner.
Still thinking of an easy way to make this bottom grate easily removable for cleaning.
Top stack with sliding "door"
$7 Walmart mailbox for my AMNPS from Todd.
All put together!
First jerky run!! Cracked pepper / garlic turned out great! But this smoker is TOO small only can do 5-6 lbs at a time.
Made heat deflector out of an old sheet pan. Cut and turned up one side and brazed the corners.
You can see it just above the bottom grate. I put about 15 3/4" holes in this pan to allow air / heat circulation.
I still want to work on door seal as it leaks a bit. Maybe will add some felt / ribbon gasket.
So far I've done jerky, beef ribs and a few butts. All with good results, but I'm still learning. The AMNPS from Todd runs great
good smoke and long burns. I run the intakes wide open and close down the top vent to about 20% open. This helps retain heat
and gives me a good TBS.
Thanks to all of you who have posted your mailbox mods and shared your experiences!!!
