I call this version 3.0
I took the underperformed "Flame Crasher" and knocked out the heat riser portion of the core and repacked cob to create a standard 4 inch batch box with a round heat riser. There is nothing fancy about this one. The numbers are straight off Peter's Batch Box chart. Here is the first burn as it was settling to coals.

It took a couple of minutes after tossing that half rotten and somewhat wet wood in the box for the smoke to clear.

Then I realized I was giving it too much air. A makeshift air inlet from some brick and block and I got a clear burn.

Even though I was not getting the perfect "ram horn" pattern the the flame crasher was doing I noticed a lot more heat was coming from the riser. I had to hold the camera at least 3 ft above the riser so I would not damage the camera (or burn my hand.)
