Finally decided that the brinkmann was no good to use as a cold smoker, I was forever scrabbling around on t he floor so I built me a new box for the CSG recently purchased from Macsbbq.
The larger chamber is for the food the smaller one (right hand pic) is for the CSG. There is a hole between the 2 bits and holes in the bottom left and top right of the left and right box respectively.
I am beginning to think the vents I have (holes) are not sufficient, I have drilled around 40, 3mm holes on the left to feed air in and around 20 on the right to let smoke out. I posted elsewhere regarding the CSG going out, I am thinking this might be due to lack of air. I removed the door this morning for a test run and things seem to be going okay, over an hour later.
How big are the vents in any of the units you guys have made. The reason I went for multiple small holes was to keep creatures out, I think I may have to rethink and perhaps buy some gauze. Across the top of the main chamber is a piece of plastic to keep the weather out, fortunately due to the woodworking skills I have there is a nice gap at the top to let the smoke out, if I tighten up the nuts too much this starves the flow and seems to cause me issues, it is now loosely fitted, but hopefully still weather resistant.
Do you think I should drill some larger holes in the smaller door, I might even enlarge the hole between left and right side too.
