Here is the external layout of my forge body right now. Internally I was planning on making the workspace an oval shape cause I have read it will help the heat move more evenly. I have never tried this before so I really don't know how necessary that is. I was keeping the cavity small by design ( 5 inches, at the widest point on of the oval) just to keep the volume down but that size and shape are really both flexible right now. I wanted to wait until I had a good interior design before i fit any burners or poured my refractory. Thank you for your time and Input Frosty, it is much appreciated.
