I have been usoing a household oven to cure my projects for a while now. I decided to build a new bigger oven with attached spray booth. It is 8′ long 3′ tall (inside), and 25″ deep (front to back). I made a rolling cart so that I could shoot the parts , then roll them into the oven on rails made from metal stud baase plates. I am no sheet metal worker,so I’m sure it is not perfect. I was able to use the old ovens parts,including that glass and interior light. The door to the oven slides out of the way when loading the oven .
