These patio fire places are a great idea to have a nice quick relaxing camp fire outside on your patio or deck. I have found that if there is no breeze outside and the air is still its hard to keep a fire going.
I spent many nights fanning a newspaper trying to keep it going which kinda took the fun relaxing part out of it so this is a idea i came up with .

Step 1: Main Pan

First i took the main pan and drilled a 5/8s hole in the center.

Step 2: Brackets

I cut 2 pieces of angle iron 1 1/2 by 1 1/2 by 2 inches. Drilled a 1/8 inch hole in one side on both pieces and 5/8 hole in the other 2 sides.

Step 3: Air Tube Parts

All parts are 5/8 black iron piping. 1 tee,2 4 inch nipples, 2 end caps, 1 90 degree elbow, a 6 inch nipple and a 8 inch nipple.

Step 4: Drilling Air Flow Holes

I drilled 10 1/8 inch holes evenly down the length of the tube and tee

Step 5: Assembling the Brackets

I cut slots in the 5/8 s holes on the 2 brackets to make it easier to center the tube .and for welding it together .I used two 1/8 inch by half inch screws and bolted the 2 brackets 3 inches from either side of the center hole.
