What is the best way to make a propane burner for a 55 gallon drum bbq grill w/standard lp valves?

Question:I made my old gas grill into a 55 gal. spit/grill. The replacement burners don't provide even heat distribution. I thought of making my own burner. I am just not sure of what materials are best. Steel type, hole size, ventilation, etc... The grill operates off of the stock dual lp valve control.

Answers:
Instead of being involved with a lot of piping and hassle, go to a BBQ cooker store, propane store, or a good hardware or home center and look at the replacement burners. There are lots of different shapes and varieties of hole patterns and they are all tested for gas and air flow.
