Thanks. A little disheartening to me. I build my basket almost the exact same way you do, but I use lump charcoal and just dump it on top of the unlit rather than in a cavity like yours. 6 chunks of wood just like you place them. But I get at minimum an hour of white smoke. And any time I raise the temp I get more white smoke. Somebody suggested using a lot less wood (1 or 2 chunks), and somebody else suggested loading the chunks into he chimney at the start. But you seem to use 6 chunks just fine. I guess I'll try making the cavity for it next time.
