so I looked all over the web and watched Youtube videos to try and find a good way to make a cold smoker. This went on for almost a week, I almost shelled out $70 for an attachment to my existing hot smoker. Well this morning I needed to start smoking, so I looked in my basement for something to just "get by" I grab a heavy metal deep junction box I had laying around. filled it 1/3 of the way with wood chips and hit the wood chips with a cutting torch for about 60 seconds. I then blew the fire out, then filled the rest of the junction box with wood chips and put it into my smoker. My smoker is powered off. This has been smoking like a Dead concert for a solid hour. The temp of the box is setting at 50 degrees. The total cost of my entire cold smoker... $1.38 I suppose I could also have used a large cardboard box to smoke in, instead of my smoker. as you can see it seems to work great. The smoker in the picture is a Masterbuild electric smoker. At this point, I may just use it keep temperature and use my junction box as the main smoking element of the smoker. It seems to work a lot better.
