BBQ Grill Coffee Roaster

Parts list:

1. a 4-burner grill
2. a square-rodded roasting drum with agitation fins inside. I used a perforated stainless wastebasket, some stainless sheet for the fins (pop-rivited inside) and a steel strap to locate the square rod. The square rod came from a rotisserie set.
3. a 30rpm AC motor (excellent speed - no scorching ; got the motor from McMaster Carr) mounted on a a couple of pieces of wood to achieve the right height for lining up with the rod/motor
4. some cheapie quick-release clamps to lock the motor to the grill when needed. CLamps eliminate drilling holes in your grill sidetable.
5. a Lovejoy spider coupler for a quick mate/release between square rod and motor. Very sweet little piece of hardware, the Lovejoy spider coupler. It'll give you +/- a few degrees of slack if your alignment is imperfect. You could probably do the same with a U-joint from a socket set.
6. a vac or blower system strong enough to cool and de-chaff a couple of pounds of beans. I use a 5-gallon shopvac, a 30-gallon cardboard drum and a bif, coarse-screened strainer from Target. Shopvac is nice for quick change between vac and blow; also good for cleaning the inside the grill after it cools off.

I already had everything laying around except the motor ($30 approx) so out of pocket was low. Old vid:

Many, many very neat ideas here, by the way:
