[Homeroast] BBQ drum roasting

I've experimented over the years with different buffers between the direct 
flame and the beans in a perforated drum.  What I've discovered is that the 
direct flame still roasts coffee well, as long as the drum agitation is 
adequate.  The end result is not as good as with a buffer to shield the 
direct flame from the beans.  I usually roast an 8 lb roast, and with 
ceramic perforated tiles covering the whole flame area, the roast is too 
slow.  I now use the perfed ceramic tiles only directly under the roasting 
drum, with plenty of space around the perimeter for the heat to rise.  Using 
a cookie sheet as a buffer did not work. The roast result was dismal.
