The initial fire up was awsome! a propane plume of flame 9"in dia & 20" long!! after a slight adjustment I let her pre heat for 10 min. I didn't have (the patence to make)the oil feed tank ready yet so I am pouring oil into the top oriface for the test.

In the second photo you can see some trailers from the oil burning(yes the longer it burned the more cracks develop from the uneven heat build up in the clay body)

the 3rd photo is less than a pound of pressure on the propane & mostly oil combusting! the goofy thing seems to work. back to the drawing board though & make a more flexable unit & improve that heat exchange for better  "self sustaning" performance. No smoke to speak of (not counting the pool of hot oil flowing out of the body of the unit:-) 

biggest disapointment? the flame is still thick & bright yellow (very bright as the irus of the camera showes) boo. i wanted a "Blue Flame"!
