Remember that old rusty sink I pulled out of the woods?stove I bought and repaired?
Well, I painted and reinforced the inside of the sink.
Then I screwed an old rusty commercial cookie sheet to the wall to protect the wood from any grease and flames.
It's a pretty tiny space to cook in, but it works just fine because of the layout.
And I don't need a vent fan. Even when I fry bacon.
