I'm also working on a smokehouseOK, I’m starting a project of building a smokehouse out of an old refrigerator,too. About a year ago I got and old refrigerator gave to me, under the assumption that it work, and I’m sure it did when they took it out of the kitchen. Well when I got it home it didn’t work, I kept it with the idea of a few different projects, and the one that seemed to have won out is a smokehouse for cold smoking. It has some plastic inside but the sides are metal, so my plans are to remove the freezer and plastic out, and cut a 4” hole in the top and bottom of one of the sides. I have a used 16 gal oil drum that I will clean up, cut down to make a smoke box out of using an electric hot plate and saw dust pan or chip box, also going to put a hot plate in the bottom of the refrigerator for a heat source.
For now I’m going to just manually control the heat with an external switch and temperature gauge. With near future plans of adding a thermostat controller to it, as soon as I find a old oven to use the controller out of or save enough money to buy one.
I’ve studied several different web sites on building a smokehouse out of a refrigerator, but all seemed a little incomplete. I keep asking myself if I’m forgetting something, so I’m asking for any ideas or suggestions that might be out there.
