I roast with a heatgun and stainless steel bowl, but I put a screen
colander inside the bowl. Much of the chaff blows out during the
roast.
To cool the beans, I cut a circular hole just large enough for the
colander in the end of a cardboard box. I put the open side of the box
next to a box fan and pull air through the beans in the colander. When
I think of it, at the end of cooling I turn the fan around so that it
blows air into the box and up and through the beans in the colander,
and that blows out the remaining chaff.
I do this out on the porch; it would b messy inside.

Roast outside. The chaff will fly out of the bowl and drift away.
I roast with a bowl within a bowl; much of the chaff actually collects  
between the bowls. Then I blow the HG between the bowls and create a  
chaff-storm for my kids :)
When I cool in a colander over a fan, any remaining chaff blows off.
