Yeah, roasting smoke becomes noticeable and smells change shortly before 1st crack starts (using heatgun). And yes, more smoke when entering 2nd, if I make it that far.

Yeah, I'm planning on building a cooler sometime soon. I have most of the parts. At the core is the coffee filter pan portion from a percolator coffee urn. There is a central tube which I'm going to run a bolt through, I have a motor that turns at a stately pace (field effect motor with gear train, not sure of the exact RPMs), and I plan to build a mixing blade out of a strip of oak I have. The fan I'll use is a like a 10" diameter muffin fan (round case). We'll see how long it actually takes me to find the time to build, but I have a plan, anyway. Just need to figure out how to attach the motor to the pan. If I do pull this off, I'll be sure to post pics :)

I have another percolator urn that I'm dreaming of turning into a roaster :D
