I put together a cold smoke attachment for the smoke vault & it's working great so far. It really puts out the smoke. Used a $5 stainless tea pot from Walmart & drilled some hole in the bottom of it for air. I used some 1" pipe I had in the shop with a T. Threaded a piece of 3/8" pipe into it & hooked up an old fish tank pump to it to push the smoke into the smoke vault. The nice thing about using the teapot is that it has a big opening and I am using chunks of wood instead of chips or pellets. Just set it on a hot plant & I was in business. Cold smoked some lox & about 5# of cheese this afternoon & first taste was really good.
