Pork belly is nearing it's time in the cure. In the past I have used both the Egg and the RF for cold smoking. Worked well but....want to hang the belly this time. I have a mailbox, a 3" dryer tube, an AMNPS and a spotless lined 55 gallon drum. Also have some hanging hooks. Plan is to pop a hole in the bottom of the drum for the dryer hose. Connect the mailbox to the other end. Hang the meat from some wooden dowels. Was just going to drill a 4" hole in the lid for exhaust. Last I looked we are supposed to be having rain/snow over the 4 days I am planning on cold smoking. So I am thinking.....grab some 1" black floor flanges (biggest I can find local on short notice) and using short nappies with 90* elbows to keep the moisture out. How many of these 1" flanges should I use? I am thinking 3 would be enough? A member on another site has suggested just placing some angle iron across the top of the drum and putting a piece of plywood, larger than the drum with a block on top of it. I may just go this route....hell of a lot easier.
