Full Length Drum Rocket Oven

Hi, I don't know if someone has asked this before, but here it goes, will the rocket burner heat (evenly) a full length (minus 8 inches to fit the  chimney) steel drum, the one in the video is too short for my needs.

Or Can I build kind of Y in the heat riser to heat to points istead of the middle of the drum?

Have anyone done it?

Thanks.

Based on the way you phrased the question, I presume you are referring to a 55-gallon steel drum that is on its side?  If so, the quick answer to your question is "probably not", but it depends on the placement of the flue (exit) and whether or not gases are stratifying before they exit.  

Can you provide some kind of drawing of what you propose?

If it's a white oven,  I would think yes,  it's already built to circulate hot exhaust around the inner drum.
In a black oven,  a plate of thermal mass right in the exhaust stream can even out the heat distribution.

Yes I'm sorry, a 55 gallon on its side, I want a white oven.

Is it too crazy to place the heat riser on the front and then make some kind of spiral  between the inner and outer barrek, so the heat travel around it until it goes out trough the chimney.
