This was the 110 gal. fuel oil tank that came with my house. I filled it with water and a bottle of dish detergent and let it soak for a couple of weeks, cut it with a grinder. The firebox is a stainless DE filter from commercial pool connected to the cook box with three 1.5" steel pipes with two 45 deg connectors in between. The firebox is offset to the back side.
It maxed out at 225 to 250 deg. F. I could get it to 300 F if I pushed it.
Then I got to reading a bit in here and realized I was loosing my heat out the smokestacks and loosing the smoke too. So off to Home Depot for some 4" dryer vent, 3 - 4" connectors and 3 - 4" hose clamps. I centered them under the smoke stacks and ran them down to the cooking surface. The center directly to the back, the end ones to the front corners.
I did test burn yesterday. It came up to temp in half the time, increased my cooking temp by 30 - 50F and evened out the surface temp to between 5 and 10 F across the surface.
I have a pork tenderloin and a brisket in there now so we'll see. I already had to cut back on the air intake to keep the temp down.
Thanks folks for the info.
