I recently started making sausage and ran out of room in my small vertical smoker. I did some research on here and saw a few designs I liked and decided to give it a shot. I found a few designs from others on here that I liked, and decided to try out my own. Below is one that I modeled mine from.

Below are a few pictures to show my progress. I used tongue and groove wood siding from Menards, and put a stain/waterproofer on the outside to help with longevity.
I'm looking to add a brick firebox outside of the smoker so I can control the heat better, but will have to wait for warmer and dryer weather before putting that together. I am also thinking about lining the bottom of the smokehouse with with sheet metal to protect the wood where the heat will be coming into the smoke chamber.
Any suggestions that from others that have built one before would be much appreciated.
