Well I really blew it this time... I converted our old Amana refrigerator to a dry-curing chamber with a MyPin TA4 temp controller and a WH8040 humidity controller. It was working well, so I screwed in some L-channel aluminum brackets and hung up some hams to dry. Everything was good. Then yesterday I decided to add a couple of PC fans to improve the airflow, one on each side. I got my 3" hole saw and cut two holes for the fans. All good. Then, when I went to drill a tiny little hole for a screw to hold the fan, I hit a Freon line! Woooooossssshhhhh! I wrecked my refrigerator! Doh! So now I have a non-functioning fridge with racks for hanging meat, it seems like my best option is to move this thing out to the barn and convert it over to a cold-smoking chamber. I'm sure somebody here has done one of these conversions before, so I'm looking for advice. Any tips on exhausting fumes out of the barn? How to build a firebox and connect it to the smoker? Do i need to strip the plastic from the inside of the fridge? What about the foam insulation? I'm pretty handy at rigging things up, but I don't need any more drama after this latest catastrophe, so any advice is appreciated!
