Hi all, I am new to the forum, I picked up a commercial freezer and started hacking the guts out of it to make a hot/cold smoker. I'm going to strip the foam insulation out of it this weekend and replace with rock wool insulation and reline the inside with 20ga 304 ss and tig weld all the seams. This is the easy part for me, the hard part is all the little things to add and trying to make sure there is even heat throughout (no hot spots). Is there any thing you wish you had put in your smoker that you didn't or done different? is there a way too make even heat throughout? What size vent? (I have some 4" 304 tube that I can fabricate one out of) Does it matter where the vent exits? Do I need to have air inlets? The only thing I'm pretty sure of is the 220 heating element and the AMNPS smoke generator. I've been doing so much research that my brain is on smoker overload, sorry for all the questions. Thank you in advance for input. I will up date the progress as I go along!
