Rob, All and all....excellent job! Very detailed and the photos will help many. Good presentation. I do have a couple of observations. One, if the ceramic wool is loose in there, bits of it may find its way into the lungs. Find some sodium silicate (liquid glass) maybe at a pharmacy and put it in a spray bottle and soak the ceramic wool. When it drys, you will have a tough surface which will better survive abrasions. As it is now, the furnace would probably be better suited for shell casting as it won't take long to dewax the shell. Investment burnout will require maybe up to 16 hours at an ascending temp. of 150+/- per Hr. and temp gauges top and bottom. Congradulatios! Frank
